<h2>Understanding Emission Data</h2>If you’ve ever been responsible for an annual emissions inventory, you know the feeling.You spend weeks gathering fuel data, throughput numbers, operating hours, emission factors. You reconcile spreadsheets. You double-check formulas. You answer follow-up questions. You finally submit the report.And then… the file gets archived.Twelve months later, you start the process all over again.For a long time, that was normal. Emissions data existed to satisfy regulators. Once the report was submitted, the job was done.But over the last few years, I’ve seen something shift.The same data companies collect for compliance is now being requested by:<ul style="list-style-type: square;" data-mce-style="list-style-type: square;"><li>ESG teams</li><li>Corporate sustainability groups</li><li>Investors</li><li>Banks</li><li>Supply chain partners</li><li>Executive leadership </li></ul>And suddenly, what used to be “just a regulatory exercise” becomes a strategic conversation.The problem is: most systems weren’t built for that.<figure id="figure-w466igc37ormlvcvsqr"><img id="w466igc37ormlvcvsqr" src="https://cdn.durable.co/getty/9BYg5dzuFxEcAFcw3IQOJiI4DRp93WvjMbhQoag5hapEwVV1kV3CQC85Bca44Klh.jpeg" alt="emission data analysis" class="object-cover bg-gray-100 rounded-lg md:rounded-xl lg:rounded-2xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/9BYg5dzuFxEcAFcw3IQOJiI4DRp93WvjMbhQoag5hapEwVV1kV3CQC85Bca44Klh.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure><h3>From the User Side: “We Have the Data… But It’s Locked in Files” </h3>When I talk to environmental managers, the story is often the same.They do have the data.Scope 1 calculations? Done. Combustion totals? Available. Tank emissions? Calculated.But the data lives in:<ul style="list-style-type: square;" data-mce-style="list-style-type: square;"><li>Separate spreadsheets by site</li><li>Consultant-owned calculation files</li><li>Archived PDFs</li><li>Email attachments</li><li>Desktop tools </li></ul>So when leadership asks:“What’s our five-year trend?” “Which facility is driving the increase?” “Can we model a reduction scenario?” “Can we align this with our ESG report?” The answer isn’t immediate.It turns into another mini-project.The issue isn’t lack of effort. It’s structure.The data was prepared for submission — not for reuse.<h2>Where Compliance Systems Fall Short</h2>Most traditional reporting processes are linear:<ol><li>Gather data</li><li>Calculate emissions</li><li>Generate report</li><li>Submit</li><li>Archive That’s it.</li></ol>There’s no intentional design around:<ul style="list-style-type: square;" data-mce-style="list-style-type: square;"><li>Long-term trend analysis</li><li>Multi-site rollups</li><li>Cross-report reuse</li><li>Real-time visibility</li><li>Executive dashboards </li></ul>Spreadsheets are flexible, but they don’t create infrastructure. They create snapshots.And snapshots don’t scale.<figure id="figure-r0ov05b9r9mlvcvwhu"><img id="r0ov05b9r9mlvcvwhu" src="https://cdn.durable.co/getty/fT8BJKhhnzi44oEh7dZzIPuiXXHgCuMVV7DIiCcQYwFPqkfWCntg16qm2UB6RuZ6.jpeg" alt="sustainable business practices" class="object-cover bg-gray-100 rounded-lg md:rounded-xl lg:rounded-2xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/fT8BJKhhnzi44oEh7dZzIPuiXXHgCuMVV7DIiCcQYwFPqkfWCntg16qm2UB6RuZ6.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure><h3>From a Digital Solution Perspective: Design for Reuse, Not Just Submission</h3>When we think about environmental data platforms today, the question shouldn’t be:“How do we generate this year’s report?”It should be:“How do we build a system where this data continues working for us?”That means designing around a few core principles:1. Capture Once Activity data — fuel use, throughput, operating hours — should only need to be entered once.From there, the system should:<ul style="list-style-type: square;" data-mce-style="list-style-type: square;"><li>Apply approved emission factors</li><li>Store calculations consistently</li><li>Preserve historical versions If you’re retyping or reformatting the same numbers for different reports, something is wrong in the architecture.</li></ul>&nbsp;2. Structure the Data Properly Reusable data must live in a structured database, not scattered files.When emission sources are standardized across sites, you can:<ul style="list-style-type: square;" data-mce-style="list-style-type: square;"><li>Roll up totals automatically</li><li>Compare facilities consistently</li><li>Track year-over-year trends without rebuilding models</li></ul>That’s when environmental data becomes analyzable — not just reportable.3. Build Governance Into the System Another major gap I see is governance.If you can’t clearly answer:<ul style="list-style-type: square;" data-mce-style="list-style-type: square;"><li>Who entered this data?</li><li>When was it changed?</li><li>What was the previous value?</li><li>Who approved it?&nbsp; Then the data may satisfy a regulator, but it won’t inspire confidence at the executive level.</li></ul>Reusable data must be defensible data.That requires:<ul style="list-style-type: square;" data-mce-style="list-style-type: square;"><li>Audit trails</li><li>Version history</li><li>Approval workflows</li><li>Data locking after review</li></ul>Without those controls, every reuse introduces risk.<h2>What Changes When Data Becomes Reusable</h2>When environmental data is structured and governed properly, something interesting happens.Annual inventory season stops being a crisis.Instead of rebuilding numbers, you’re reviewing them.Instead of scrambling, you’re analyzing.Instead of reacting, you’re planning.And beyond compliance, you gain the ability to:<ul style="list-style-type: square;" data-mce-style="list-style-type: square;"><li>Provide instant responses to ESG questionnaires</li><li>Support sustainability-linked financing discussions</li><li>Identify high-emission assets</li><li>Benchmark sites</li><li>Track reduction progress quarterly instead of annually The data stops being static.</li></ul>It becomes operational intelligence.<figure id="figure-kepiweos5dmlvcvzym"><img id="kepiweos5dmlvcvzym" src="https://cdn.durable.co/getty/13nwbbtntsvY8cwUZyQEd9ELrdlPINkhDn4Lh9vg8LqNU2rEz7kp7kqaLLEsDNev.jpeg" alt="technology in emissions" class="object-cover bg-gray-100 rounded-lg md:rounded-xl lg:rounded-2xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/13nwbbtntsvY8cwUZyQEd9ELrdlPINkhDn4Lh9vg8LqNU2rEz7kp7kqaLLEsDNev.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure><h3>The Real Competitive Divide</h3>In my experience, the difference between companies that struggle and companies that move confidently in this space isn’t expertise.It’s infrastructure.Both may have capable environmental teams.But one relies on manual files and fragmented systems.The other has built a digital backbone that allows data to flow across reporting frameworks without being recreated each time.The second group isn’t working harder.They’re working on top of better architecture.<h3>A Simple Shift in Mindset</h3>Instead of asking:“How do we finish this year’s inventory?”Start asking:“How do we make sure this data serves us next year — and beyond?”Because environmental reporting isn’t getting simpler.Requests are increasing. Transparency expectations are rising. Scope boundaries are expanding.If the data isn’t reusable, the workload will keep growing.If it is reusable, each reporting cycle becomes easier than the last.<h2>Final Thought</h2>Environmental data should not expire after submission.It should compound in value.<figure id="figure-jkyhk0fxusmlvcw58s"><img id="jkyhk0fxusmlvcw58s" src="https://cdn.durable.co/getty/19Dvg8QNfEgT9Dj7OkQmJhsiTsuUtzDPi3BCimzc0GICJU5oAlAVNGf5YWJUuMUW.jpeg" alt="future of sustainability" class="object-cover bg-gray-100 rounded-lg md:rounded-xl lg:rounded-2xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/19Dvg8QNfEgT9Dj7OkQmJhsiTsuUtzDPi3BCimzc0GICJU5oAlAVNGf5YWJUuMUW.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure>When captured properly in a structured digital platform, the same dataset can power:<ul style="list-style-type: square;" data-mce-style="list-style-type: square;"><li>Regulatory reporting</li><li>ESG disclosures</li><li>Internal dashboards</li><li>Reduction planning</li><li>Executive decision-making</li></ul>Compliance will always be required.But with the right system in place, compliance becomes the foundation — not the finish line.

<h2>The Importance of Emission Reporting</h2>For many organizations, annual emission inventory reporting is one of the most time-consuming and stressful parts of environmental compliance. Data must be gathered from multiple sources, calculations must be consistent, assumptions must be documented, and everything must stand up to internal and external review.Yet despite increasing regulatory scrutiny, many companies still rely on spreadsheets, emails, and legacy desktop tools to complete their annual inventories. The result is often duplicated effort, inconsistent data, and a lack of confidence in the final numbers.Digital environmental data management platforms are changing this process entirely. By centralizing data, automating calculations, and enforcing governance, modern platforms simplify emission inventory reporting while improving accuracy and audit readiness.<figure id="figure-09p7zwwu2mkbkd3qg"><img id="09p7zwwu2mkbkd3qg" src="https://cdn.durable.co/getty/1b5QLlZ9FW3Hnq7eUYCYed5t3IjFm6XFsJ4DjJcSbAZZuUR4R8jTXIggspBWd35k.jpeg" alt="emission reporting" class="object-cover bg-gray-100 rounded-lg md:rounded-xl lg:rounded-2xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/1b5QLlZ9FW3Hnq7eUYCYed5t3IjFm6XFsJ4DjJcSbAZZuUR4R8jTXIggspBWd35k.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure><h2>The Complexity of Annual Emission Inventory Reporting</h2>An annual emission inventory is rarely a single report. It is the culmination of months of data collection across multiple emission sources, sites, and teams. Common challenges include:<ul><li>Collecting activity data from different departments and facilities</li><li>Applying consistent emission factors and calculation methodologies</li><li>Managing revisions, approvals, and late data updates</li><li>Responding to internal QA/QC reviews and external audits</li><li>Reusing the same data for regulatory, corporate, and ESG reporting</li></ul>When these tasks are managed manually, errors are difficult to detect and even harder to trace. Small inconsistencies can cascade into major reporting issues, especially for multi-site organizations.<figure id="figure-wie8bqgwyimkbkd86e"><img id="wie8bqgwyimkbkd86e" src="https://cdn.durable.co/getty/2067vZaGuL09h8QEgWOHcTII2SimxxCShZ8MFCvDptH8FDBpXmtJjyc8OF4PFC6B.jpeg" alt="digital tools" class="object-cover bg-gray-100 rounded-lg md:rounded-xl lg:rounded-2xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/2067vZaGuL09h8QEgWOHcTII2SimxxCShZ8MFCvDptH8FDBpXmtJjyc8OF4PFC6B.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure><h2>Centralizing Environmental Data in One System</h2>One of the biggest advantages of digital platforms is centralization. Instead of maintaining separate spreadsheets for tanks, engines, fugitives, and utility usage, all emission data is stored in a single, structured system.This approach provides:<ul><li>A single source of truth for all emission sources</li><li>Standardized data fields across facilities</li><li>Controlled access based on user roles</li><li>Immediate visibility into missing or incomplete data</li></ul>With centralized data, teams no longer waste time reconciling versions or searching for the “latest” file. Everyone works from the same dataset, reducing confusion and rework during reporting season.<h2>Automating Emission Calculations</h2>Manual calculations introduce risk. Broken formulas, copy-paste errors, and inconsistent assumptions are common when spreadsheets are used year after year.Digital platforms simplify reporting by automating emission calculations based on approved methodologies and emission factors. Once activity data is entered, emissions are calculated consistently across all sites and sources.Automation delivers several benefits:<ul><li>Reduced human error</li><li>Faster completion of inventories</li><li>Consistent methodology across reporting periods</li><li>Easier updates when emission factors change</li></ul>For example, storage tank emissions, combustion sources, or process emissions can all be calculated using standardized formulas that align with regulatory guidance, eliminating guesswork and manual manipulation.<figure id="figure-t1bztrgeinmkbkdcvi" class=""><img id="t1bztrgeinmkbkdcvi" src="https://cdn.durable.co/getty/26cGiooxBLJdLCbwXtVZGsGopBmiUFtD2zdQpipaiM7xy9bE307sUkS5brYZvwTr.jpeg" alt="cloud computing" class="object-cover bg-gray-100 rounded-lg md:rounded-xl lg:rounded-2xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/26cGiooxBLJdLCbwXtVZGsGopBmiUFtD2zdQpipaiM7xy9bE307sUkS5brYZvwTr.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure><h2>Built-In Data Validation and Quality Checks</h2>Annual emission inventories often fail QA/QC reviews due to incomplete or questionable data. Digital platforms address this by embedding data validation rules directly into the system.Common validation features include:<ul><li>Required fields for critical inputs</li><li>Range checks to flag unusual values</li><li>Automated completeness tracking by site or source</li><li>Visual indicators for missing or unapproved data</li></ul>These controls help identify issues early, long before final reports are generated. Instead of discovering problems weeks later during review, teams can resolve them in real time.<h2>Simplifying Review, Approval, and Audit Readiness</h2>One of the most overlooked challenges in emission inventory reporting is governance. Regulators and auditors increasingly expect clear documentation showing who entered data, who reviewed it, and when changes were made.Digital platforms simplify this by providing:<ul><li>User-level change tracking</li><li>Time-stamped audit trails</li><li>Data locking after approval</li><li>Clear separation between draft and final data</li></ul>Once data is reviewed and approved, it can be locked to prevent accidental changes. If updates are required, the system records exactly what changed and why. This level of traceability builds confidence in the reported numbers and significantly reduces audit stress.<figure id="figure-q84ufmpp5nmkbkdic9"><img id="q84ufmpp5nmkbkdic9" src="https://cdn.durable.co/getty/2d78SnoZJ8356F09nflNWkUQi0mHMwt7wHZkriIbGU44ETW2d4CMzl6zGw5r7rPl.jpeg" alt="software customization" class="object-cover bg-gray-100 rounded-lg md:rounded-xl lg:rounded-2xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/2d78SnoZJ8356F09nflNWkUQi0mHMwt7wHZkriIbGU44ETW2d4CMzl6zGw5r7rPl.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure><h2>Multi-Site Reporting Made Manageable </h2>For organizations with multiple facilities, annual inventories can feel overwhelming. Each site may follow slightly different processes, timelines, and data formats.Digital platforms standardize reporting across sites by:<ul><li>Using consistent templates and methodologies</li><li>Allowing centralized oversight with site-level ownership</li><li>Rolling up emissions automatically for corporate totals</li><li>Comparing performance across facilities</li></ul>This not only simplifies annual reporting but also enables better insights into emission trends, high-impact sources, and opportunities for reduction.<h2>Reusing Data Beyond Compliance</h2>Another major advantage of digital platforms is that emission inventory data doesn’t have to be recreated for every new request. Once data is structured and validated, it can be reused for:<ul><li>ESG and sustainability reporting</li><li>Corporate dashboards and KPIs</li><li>Consultant deliverables</li><li>Internal planning and benchmarking</li></ul>Instead of treating annual inventories as a one-time compliance exercise, organizations can turn them into a foundation for broader environmental and sustainability initiatives.<h2>From Annual Burden to Continuous Process</h2>The most successful organizations are shifting away from year-end scrambles toward continuous emissions management. Digital platforms support this shift by allowing data to be entered, reviewed, and validated throughout the year.When reporting season arrives, the inventory is already largely complete — reducing stress, overtime, and last-minute errors.<h2>Conclusion</h2>Annual emission inventory reporting doesn’t have to be painful. Digital environmental data management platforms simplify the process by centralizing data, automating calculations, enforcing governance, and improving audit readiness.For organizations and consultants alike, the result is faster reporting, higher confidence in results, and a stronger foundation for compliance and sustainability goals.Modern tools like DREEM Solutions help turn emission inventory reporting from a manual obligation into a streamlined, reliable, and repeatable process — year after year.<figure id="figure-z6uget3izqmkbkdn56"><img id="z6uget3izqmkbkdn56" src="https://cdn.durable.co/getty/34QOMnoJPr2kCJ3RWEcSNQil2uAYhqCH2v5ADYysSWLzgBLvbWWKSXgM3MB7kKnv.jpeg" alt="sustainable technology" class="object-cover bg-gray-100 rounded-lg md:rounded-xl lg:rounded-2xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/34QOMnoJPr2kCJ3RWEcSNQil2uAYhqCH2v5ADYysSWLzgBLvbWWKSXgM3MB7kKnv.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure>

Streamlining Emission Reporting with Digital Platforms

<h2>Understanding Emission Calculations</h2>As environmental regulations tighten and ESG reporting gains global traction, accurate emission calculations have never been more important. Yet, even with the best intentions, many organizations still fall into the same traps — inconsistent data, outdated methods, and poor traceability.Whether you’re managing emissions for one facility or dozens across different regions, avoiding these pitfalls is key to credible, defensible reporting. Let’s explore the three most common issues and practical ways to overcome them.<figure id="figure-wg5kxx0qlhmhxqiwtt"><img id="wg5kxx0qlhmhxqiwtt" src="https://cdn.durable.co/getty/2e5xhoPEghAQhx1HyojzdaOwyHpx1a3mI8n4DmOb23hChiwjgSnibkTLvi3hzWud.jpeg" alt="emission calculations" class="object-cover bg-gray-100 rounded-lg md:rounded-xl lg:rounded-2xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/2e5xhoPEghAQhx1HyojzdaOwyHpx1a3mI8n4DmOb23hChiwjgSnibkTLvi3hzWud.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure><h2>1. Using Outdated or Inconsistent Emission Factors</h2>One of the most frequent — and most damaging — errors in emissions reporting stems from inconsistent or outdated emission factors.Many facilities still rely on legacy spreadsheets or old EPA reference data that hasn’t been reviewed in years. Even a small discrepancy in a VOC emission factor or storage tank throughput assumption can drastically alter reported totals. When regulators or auditors review the calculations, these inconsistencies can lead to costly rework or even compliance violations.Example: A company using the EPA Tanks 4.09d program may continue applying default emission factors that don’t reflect current fuel specifications or local atmospheric conditions. When compared to updated AP-42 or site-specific data, the differences can be significant.How to avoid it:Maintain a centralized emission factor library that’s regularly reviewed and updated. Use system-enforced version control to ensure every calculation references the same approved dataset. Implement audit trails so users can see when and why a factor was changed. Modern environmental platforms — such as DREEM — make this simple by storing emission factors in a controlled database that can be referenced across all sites and projects. This ensures accuracy and consistency, no matter who performs the calculation.<figure id="figure-fhbhysiplmhxqj089"><img id="fhbhysiplmhxqj089" src="https://cdn.durable.co/getty/32DD8YfjKJ4l5ZyVAnKN8OKxYkT341moapUCdkjj86jTdgefvjo3J4Yequ0OHsgn.jpeg" alt="data collection" class="object-cover bg-gray-100 rounded-lg md:rounded-xl lg:rounded-2xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/32DD8YfjKJ4l5ZyVAnKN8OKxYkT341moapUCdkjj86jTdgefvjo3J4Yequ0OHsgn.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure><h2>2. Spreadsheet Chaos and Manual Errors</h2>Spreadsheets are powerful tools, but when it comes to regulatory data, they’re also risky. Manual data entry, broken formulas, and version mismatches are among the leading causes of misreported emissions.In a typical setup, you might see multiple Excel files shared via email — one for each emission source or site. By the time data is compiled, reviewed, and submitted, there’s no clear record of who made which change or which file version is the “official” one.Why it matters:Manual edits can overwrite validated data without notice. Reviewers spend valuable time verifying numbers instead of analyzing results. Regulators increasingly expect digital traceability for reported data. How to avoid it:Move calculations and data collection into a centralized cloud platform where all users access the same data source. Automate repetitive calculations to reduce manual intervention. Require user authentication for all data entries and updates. DREEM replaces fragmented spreadsheets with a secure, structured system. Each update — from a throughput value to a calculation factor — is tracked by user and timestamp, eliminating the guesswork and ensuring transparency across all contributors.<h2>3. Lack of Data Governance: No Locking, No Audit Trail</h2>Even with good data and sound calculations, a lack of governance can undermine the entire reporting process. If records can be changed after approval — or without proper documentation — the data cannot be trusted.Many organizations find themselves in a difficult position during audits when asked to explain when certain values were modified and by whom. Without built-in change tracking or data locking, proving data integrity becomes nearly impossible.Why this happens:Traditional spreadsheets and older desktop tools like Tanks 4.09d lack built-in version control. Teams often rely on “naming conventions” (v1, v2, final, final-FINAL.xlsx) instead of secure, structured records. Environmental data is spread across different users and departments, increasing risk of accidental overwrites. How to avoid it:Implement a data locking mechanism once calculations are reviewed and approved. Use audit logging to store every version of each record. DREEM’s platform was built around these principles. Once a record is approved, it’s automatically locked to prevent unintentional edits. Every data change is logged with user information and timestamps, creating a full audit trail that satisfies internal reviewers and external regulators alike.<figure id="figure-xjttmuk8cemhxqj3hk"><img id="xjttmuk8cemhxqj3hk" src="https://cdn.durable.co/getty/7k9CpJIVcxrcUC3r0Gc3wVFii7BBBKQQL7CMjiiPpoHRI2tAIgxROzPhYBdGijTK.jpeg" alt="regulatory compliance" class="object-cover bg-gray-100 rounded-lg md:rounded-xl lg:rounded-2xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/7k9CpJIVcxrcUC3r0Gc3wVFii7BBBKQQL7CMjiiPpoHRI2tAIgxROzPhYBdGijTK.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure><h2>Bonus Pitfall: Ignoring Scope 3 Emissions Planning</h2>As global reporting frameworks expand, more companies are being asked to account for Scope 3 (value chain) emissions. Even if it’s not mandatory yet for your business, planning early can save time and resources later.Building Scope 3 readiness means having systems that can integrate supplier data, manage assumptions transparently, and maintain clear documentation for every input.DREEM’s modular design makes it easier to grow into this space — you can start with Scope 1 and 2 emissions today, and seamlessly extend to Scope 3 when your organization or clients are ready.<h2>Building Confidence in Your Emission Calculations</h2>Accurate emission reporting isn’t just about compliance — it’s about credibility, efficiency, and reputation. Regulators, investors, and stakeholders are increasingly focused on data transparency, and that starts with getting the basics right.Avoiding these pitfalls comes down to three core principles:Standardization – consistent factors, formulas, and methods. Automation – reduce manual work to limit errors. Governance – track, lock, and verify every data change. Environmental compliance software like DREEM empowers organizations and consultants to manage these steps seamlessly, ensuring every calculation is consistent, traceable, and defensible.#EmissionCalculations #EnvironmentalCompliance #SaaS #DataIntegrity #Scope1 #Scope2

Three Critical Emission Calculation Pitfalls

<h2>Understanding Subpart W GHG Emissions</h2>Greenhouse gas (GHG) emissions have long been a critical concern in global discussions about climate change. Subpart W of the Greenhouse Gas Reporting Program (GHGRP) focuses specifically on emissions from the petroleum and natural gas systems, sectors that are significant contributors to overall GHG levels. As the world continues to grapple with climate change, tracking these emissions has never been more crucial.<figure id="figure-1a1udmapxmgtpogm4"><img id="1a1udmapxmgtpogm4" src="https://cdn.durable.co/getty/11UrWp5I4Bi2YIA3MJVaRw1jGhfQyW0pO9khAU9qvUyL3RnrETfSBdoFZhZgOZBq.jpeg" alt="oil refinery emissions" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/11UrWp5I4Bi2YIA3MJVaRw1jGhfQyW0pO9khAU9qvUyL3RnrETfSBdoFZhZgOZBq.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure><h2>EPA Proposed Changes</h2>In eptember 2025, the U.S. Environmental Protection Agency (EPA) announced a major proposal to scale back its Greenhouse Gas Reporting Program (GHGRP),&nbsp; a move that could pause or even eliminate GHG reporting for many industries. While this proposal is still under review, it has already created uncertainty for operators and compliance teams across the oil and gas sector.But one thing remains clear: tracking greenhouse gas (GHG) emissions,&nbsp; especially under Subpart W, is more important than ever.Even if federal reporting obligations are delayed or suspended, emissions data remains critical for state programs, investors, and international markets that continue to demand transparency and accountability.&nbsp;What’s Changing: EPA’s Proposed Revisions to the GHGRP Under the EPA’s proposed rule:Reporting obligations for 46 of 47 GHGRP source categories would end after the 2024 reporting year. Subpart W (Petroleum and Natural Gas Systems) reporting would be suspended from 2025 through 2033, with obligations resuming in 2034. The Natural Gas Distribution segment would be permanently removed from GHGRP reporting. These changes are linked to updates in the Clean Air Act (CAA), which delayed implementation of the Methane Waste Emissions Charge (WEC) until 2034. Although the proposal aims to reduce administrative burden, the EPA acknowledged that companies may voluntarily continue collecting and maintaining emissions data — a prudent move for any operator preparing for future regulations and stakeholder scrutiny.<h3>Why Companies Should Continue Tracking Emissions</h3>The potential pause in federal reporting does not eliminate the broader need for accurate, verifiable GHG data. Here are key reasons why continued tracking under Subpart W methodologies remains essential:1. State and Regional Programs Still Depend on EPA Methodologies Many state-level GHG programs — including those in California, Colorado, Washington, and New York — use the EPA’s Subpart W calculation methods as their technical foundation. Companies that stop tracking emissions could struggle to meet state or local reporting requirements, losing consistency and compliance readiness.2. Investor and Financial Market Expectations Are Not Retreating Despite the proposed rollback, ESG-focused investors, lenders, and insurers continue to assess companies based on GHG performance.Investors rely on verified emissions data to evaluate climate-related risks. Creditors and insurers increasingly factor emissions intensity into financial terms. ESG rating agencies continue to rank and compare companies on carbon transparency. Companies that fail to track and disclose credible data risk being penalized in capital markets and losing the trust of investors and customers.3. Global Trade and Carbon Border Policies Require Transparency International policies such as the EU Carbon Border Adjustment Mechanism (CBAM) require exporters to demonstrate verified emissions data. For companies engaged in global energy, LNG, or chemical trade, accurate emissions tracking under Subpart W methodologies remains a strategic necessity for maintaining market access and competitiveness.4. Operational Insight and Risk Management Beyond compliance, robust emissions data enables better decision-making:- Detecting leaks and inefficiencies in real time - Establishing reliable baselines for emission reduction targets - Supporting internal sustainability initiatives and performance tracking - Maintaining credibility with communities, partners, and regulators - Strong data governance today ensures auditability and readiness for the next&nbsp; &nbsp; &nbsp;phase of climate regulation.<figure id="figure-37o5xb2w2mgtpolx9"><img id="37o5xb2w2mgtpolx9" src="https://cdn.durable.co/getty/18Ht5axPGteBFrirX12nb6Y2kov1F8Rtxd1KLpp4TG5p6OXOQsZNSNY0kgFqaeEV.jpeg" alt="environmental regulation" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/18Ht5axPGteBFrirX12nb6Y2kov1F8Rtxd1KLpp4TG5p6OXOQsZNSNY0kgFqaeEV.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure><h2>Lessons from the 2024 Subpart W Updates</h2>Before the 2025 proposal, the EPA had already finalized major updates to Subpart W to improve accuracy and transparency. These included:Adding new source categories (e.g., produced water tanks, crankcase vents, large release events) Requiring more direct measurement where feasible Aligning data requirements with other EPA programs such as NSPS OOOOb These updates represent best practices for emissions tracking — and many organizations are continuing to use them as their standard, even if federal reporting pauses.<h3>The Path Forward: Stay Ready, Stay Accountable</h3>Companies that continue tracking emissions will be better positioned for the future, both operationally and reputationally. Best practices include:Maintaining Subpart W-based monitoring and data management systems even if reporting pauses. Implementing third-party verification and audit trails to preserve data credibility. Monitoring state, regional, and investor disclosure requirements to stay ahead of emerging rules.

<h3>EPA Tanks 4.09d: Shortcomings and Modern Alternatives for Accurate Storage Tank Emission Calculations </h3>For years, EPA Tanks 4.09d (commonly referred to as Tanks 4) was the standard desktop software used to estimate volatile organic compound (VOC) and hazardous air pollutant (HAP) emissions from storage tanks. It was widely adopted by facilities and consultants to help meet EPA and state air quality compliance requirements.The program could estimate emissions for multiple tank configurations, including:- Vertical and horizontal fixed-roof tanks - Internal and external floating-roof tanks - Domed external floating-roof tanks - Underground tanks However, the EPA has officially discontinued support for Tanks 4.09d, acknowledging that it no longer aligns with current regulatory methodologies or data accuracy needs. This has created a growing need for modern, accurate, and user-friendly alternatives to ensure ongoing compliance and reliable emissions estimation.<figure id="figure-nzl9t6i8njmh2hygvm"><img id="nzl9t6i8njmh2hygvm" src="https://cdn.durable.co/getty/2tPYhlIdhzOOJjURjWVD9bAvvVLpPfAwq740wvl1l78WvOr8gFiuj5WYlHNoH9C7.jpeg" alt="environmental regulations" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/2tPYhlIdhzOOJjURjWVD9bAvvVLpPfAwq740wvl1l78WvOr8gFiuj5WYlHNoH9C7.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure><h3>The Limitations of EPA Tanks 4.09d</h3>Although it served the industry for decades, Tanks 4.09d contained several critical shortcomings that often led to inaccurate VOC and HAP emissions results. Below are some of the key issues that users and regulators have long recognized.1. Oversimplified Bulk Temperature Calculations Tanks 4.09d used the average annual ambient temperature of a tank’s location to estimate the liquid bulk temperature for non-heated tanks. This method ignored monthly temperature variations, leading to over- or under-estimations of emissions — particularly when calculating monthly totals.2. Temperature Limitations for Heated Tanks The software capped vapor pressure interpolation at 100°F, even though many heated tanks operate above this temperature. As a result, vapor pressure and emission estimates were understated for tanks running hotter than 100°F.3. Unrealistic Full-Insulation Assumptions Tanks 4.09d assumed that all heated tanks were fully insulated, which set standing losses to zero by default. In reality, partial insulation or uninsulated roofs lead to measurable standing losses — which the program failed to capture.4. Missing Parameters for Floating Roof Tanks The tool lacked an option to indicate whether the liquid in a floating roof tank was heated or not. This omission caused misleading emission results when calculating losses for heated floating tanks.5. No Calculations for Roof Landing or Tank Cleaning Tanks 4.09d did not include features to calculate emissions from roof landings or tank cleanings, which can contribute significantly to total annual VOC and HAP emissions.In short, while the software provided a useful foundation, it is now considered technically outdated, inaccurate, and incomplete for today’s compliance and reporting standards.<figure id="figure-6iqtbv9bgsmh2hymfy"><img id="6iqtbv9bgsmh2hymfy" src="https://cdn.durable.co/getty/9P2WRdyoDhpL8XTnPR4Diif5CWBwJnN1IDVUr35zBkj35CVdtUAwZimUa41UKwQz.jpeg" alt="industrial tanks" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9;" data-mce-src="https://cdn.durable.co/getty/9P2WRdyoDhpL8XTnPR4Diif5CWBwJnN1IDVUr35zBkj35CVdtUAwZimUa41UKwQz.jpeg" data-mce-style="aspect-ratio: 16/9;"></figure><h3>A Modern Alternative: DREEM Solutions</h3>Recognizing these industry challenges, DREEM Solutions has developed a powerful and accurate alternative to EPA Tanks 4.09d.
