Environmental Accounting Trends for Climate Action

Contrary to prevailing sentiment, greenhouse gas inventories are dramatically inadequate tools for climate target accounting. Traditional GHG reporting was designed to capture static snapshots of emissions estimates across company activities and value chains. They are definitively not designed (and are mostly unable) to reliably track the impact of mitigation actions that companies apply in their supply chains. Inventory accounting wasn't designed to distinguish between an emissions drop caused by a divestiture, a procurement decision, and a deliberate mitigation action. When all of that gets folded into one inventory number, the signal gets lost. That's one of the core problems TCAT's Mitigation Action Accounting and Reporting Guidance (MAARG) was built to solve. Task Force for Corporate Action Transparency just published a piece walking through exactly how this framework works and why the separation of inventory accounting from impact accounting is long overdue. The MAARG introduces five distinct reporting statements -- Physical, Contractual, and three Impact statements. These statements let different types of information live where they actually belong, rather than being collapsed into a single figure. One statement for your baseline footprint. One for how contractual instruments (RECs, SAF certificates, etc.) adjust that picture. Three more for the actual climate impact of the actions you've taken: in your inventory (captured as emissions impact that would otherwise not be visible in your footprint) in your sector, and beyond your value chain. On paper, five statements sounds like more complexity. In practice, it's the opposite. We drew from our experiences building the MRV architecture under the Paris Agreement to inform how this works in the guidance, and it's an essential set of distinctions to make if we really care about separating the impact of intentional climate action and the MANY changes in inventories that occur as a result of wide range of things that sustainability teams have functionally zero influence over.

The world isn’t ready for what’s coming next in sustainability data. We’re quietly living through the creation of a financial infrastructure for sustainability—and it’s happening faster than most realize. Over 2,000 sustainability regulations have emerged globally in the past decade, with a 155% surge in ESG-related rules since 2018. This isn’t just about compliance—it’s a fundamental shift in how we define value, risk, and performance. What’s driving it? • EU: CSRD & ESRS will impact over 50,000 companies, embedding double materiality. • India: BRSR Core is mandatory for top 1,000 listed firms. • China: CSDS expands carbon reporting in high-impact sectors. • California: SB 253/261 reshape U.S. climate disclosures. • Australia: AASB S2 aligns with IFRS S2, effective in 2025. • Brazil: CVM 193 adopts IFRS-aligned sustainability standards. • And more: Japan, Canada, Singapore, Nigeria, Turkey—all aligning with global standads. We’ve entered a phase where climate, nature, and transition risks are becoming embedded in financial decision-making—from underwriting and M&A to risk pricing and insurance modeling. In the real estate sector, GRESB has made third-party verified performance data (GHG, energy, water, waste) a best practice. ESG metrics are now more embedded in due diligence for loans, equity, and new acquisitions. Yes, today’s data is often backward-looking. And yes, we still need science-based thresholds and stronger assurance. But this foundational work is what allows us to get there. Without reliable, standardized, machine-readable data, we can’t scale action, track progress, or hold anyone accountable. Just as GAAP and IFRS created trust in financial markets, IFRS S1/S2, CSRD, and the GHG Protocol are setting the stage for credible, comparable sustainability data. It will not be a “parallel system.” in the future. We are building the groundwork for full integration into the global financial system. This shift will transform: • How we price risk • How capital is allocated • How resilient companies are rewarded • How we define long-term value creation It’s messy. It’s political. It’s imperfect. But it’s also historic. If you’re in this space, you’re not just reporting data—you’re helping build a new operating system for business and capital markets. One that rewards transparency, resilience, and climate alignment. Let’s keep building—with more rigor, more ambition, and more impact.

The world is changing, is the GHG Protocol following? What is happening from now until 2028? I often hear from potential customers: “These climate and sustainability rules change so much. I’d rather wait and invest when things become stable.” But the reality is waiting is riskier than acting. The Greenhouse Gas Protocol (GHG Protocol) the global baseline for corporate climate disclosure is about to undergo its biggest reset in decades. And it will redefine what credible and compliant emissions reporting looks like. What’s changing (2025–2028): 2025: Land Sector & Removals Guidance (after years of delay) 2026: Drafts of Corporate Standard, Scope 2 & Scope 3 2027: Final versions published 2028: New guidance on Actions & Market Instruments Why it matters: - Tighter rules = less flexibility, more comparability - Scope 3 & carbon market claims under tougher scrutiny - Closer alignment with IFRS Foundation S2 & EU CSRD - Closing loopholes & raising the bar for credibility - Think of this as the IFRS moment for climate disclosure, a reset of the global accounting standards for carbon. What are the top 4 things leaders should do NOW: 1- Audit your reporting: spot weak assumptions in Scope 2 & 3 2- Engage the Board: this is as much governance as sustainability 3- Invest in data & suppliers: stronger data quality = stronger trust 4- Stay close to the process: follow drafts, anticipate impacts early Companies that prepare today will not only survive stricter rules, they’ll win investor trust, attract capital, and lead in credible climate action. This is not disruption, it’s transition. And it’s your chance to turn compliance into competitiveness. A decisive decade for climate action can also be your decisive decade for credible disclosure.

For a long time, climate action felt like filing taxes: a tedious compliance exercise. In 2026, the metaphor has shifted, and carbon is now a currency with a fluctuating exchange rate. It appears simultaneously as a cost, a compliance requirement, and a competitive advantage. The capital is moving. Global energy investment is projected to hit $3.3 trillion, with a massive $2.2 trillion flowing specifically into clean technologies like renewables, EVs, and efficiency. But the trade map is being redrawn by carbon math. Borders have become balance sheets. With the EU CBAM entering its definitive regime and remaining non-negotiable in the new India-EU FTA, decarbonization has officially graduated from a CSR initiative to a mandatory market-access license. India is moving from pilots to hard policy, evidenced by the multi-billion dollar push for Green Hydrogen and CCUS and a tightening Carbon Credit Trading Scheme. We are moving past feel-good offsets and finally paying for the heavy machinery needed to clean up steel and cement; the hard-to-abate sectors that drive appx 15% of emissions. With over 25 satellites tracking methane from space and companies like Microsoft contracting for millions of tonnes of carbon removal, the market now demands proof. Measurement, Reporting, and Verification (MRV) is the new gold standard. No guesswork for emissions. Yet, we must take note of a global paradox: the world started with good intent, but today, many are holding back from making drastic policy decisions for short-term gain while ignoring carbon warnings. What will be the catalyst and courage to act? The global climate tech ecosystem is massive, with Net Zero Insights tracking over 20,000 active organisations. While energy remains the dominant category at 34% of funding, the ecosystem has splintered into specialised players, including a rapidly growing cohort dedicated purely to carbon accounting and environmental monitoring. India’s climate tech story is rapidly maturing, with the market projected to reach $1.29 billion in 2026. But the system is buffering. The transition isn’t seamless; we have the cash and the ambition, and the software is still loading. The RBI delaying climate disclosures for banks proves that while we want to save the world, our institutional back office isn’t quite ready to handle the paperwork. The catalyst for courage will likely be the realisation that carbon is a currency you cannot afford to devalue. The companies that learn to count, save, and trade will be the only ones to survive the transition. #Environment #ClimateTech #Technology

TLDR:🔍 The reason for this is simple: the climate transition is now a financial transition. Under new regulatory regimes, sustainability information must meet the same rigour as audited financials. Finance leaders have long managed materiality, assurance, and investor engagement – precisely the disciplines environmental, social and governance (ESG) reporting now demands. CFOs are becoming “the new stewards of sustainability data,” responsible for ensuring that carbon metrics stand up to audit scrutiny in the same way as financial KPIs. ✅ A new generation of CFOs is learning how to translate carbon and climate metrics into financial risk, cost of capital, and valuation. The result is a hybrid professional class – finance leaders who understand climate science, and sustainability specialists who understand balance sheets. As the sustainability function integrates with finance, the future belongs to professionals who can move fluently between both worlds. 🖊️ CFOs are also uniquely positioned to drive collaboration. They sit at the nexus of investor relations, audit, and governance – the very functions that need to align for credible climate disclosure. When finance leads the sustainability agenda, the discussion moves from aspiration to execution: how climate goals are funded, monitored, and delivered. ☑️  This is not just a compliance exercise; it’s a cultural inflection point. When CFOs start to own emissions, the tone of climate conversations will change – from ambition to accountability, from pledges to performance. And that may be exactly what the next phase of the climate transition requires. The climate transition won’t just be engineered by scientists or advocated by sustainability teams. It will be modelled, costed, audited, and financed – by CFOs. 🆕 Microsoft’s finance team now oversees sustainability reporting, integrating emissions data into enterprise financial systems to prepare for third-party assurance. Apple has tied executive compensation, including CFO Luca Maestri’s, to carbon and environmental performance metrics - embedding climate into financial governance. #CFO #sustainability #ESG #climatetransition

For years, climate action in business was defined by commitments, pledges, and ambition statements. That era is ending. We're entering the age of climate performance accountability — where GHG emissions, supply chain impacts, and operational footprints are becoming subject to the same rigor as financial reporting. On February 10, the New York State Senate passed the Climate Corporate Data Accountability Act (#S9072A). The bill requires companies with over $1B in annual revenue doing business in NY to publicly disclose Scope 1, 2, and 3 emissions. The first report — covering 2026 emissions data — is due June 2027, with third-party verification required by December 2027. Here’s what leaders need to understand: • Entities operating in NY that meet reporting thresholds — including fuel and energy suppliers, electricity generators and importers, waste haulers, fertilizer suppliers, and facilities emitting ≥10,000 metric tons CO₂e annually — must report emissions data. • Larger emitters must obtain DEC-accredited third-party verification. This is not a niche environmental rule. It is a signal that climate performance is becoming a core business metric, alongside financial risk, supply-chain resilience, and regulatory compliance. Mandated disclosure with verification isn’t just transparency. It’s credibility. At the Global Network for Zero (GNFZ), we’ve been preparing organizations for this shift — because disclosure without integrity doesn’t reduce risk or unlock capital. Verified climate performance does. The era of reporting because it’s voluntary is over. The era of reporting because it matters — and can be trusted — has begun. The question for leaders is no longer, “What are we reporting?” It’s: “Can we prove that it’s driving real performance?” That is the work ahead.

  Keeping up with proposed changes and additions to notable climate and nature standards from organizations including (but not limited to) the Science Based Targets initiative, Greenhouse Gas Protocol (GHG Protocol), Global Reporting Initiative (GRI), Science Based Targets Network (SBTN), ISO - International Organization for Standardization and so forth is time-consuming. Developments over the past few weeks alone include a call for input about the next three years of standards priorities by the Global Reporting Initiative’s Global Sustainability Standards Board focus. Elsewhere, the Science Based Targets initiative (SBTi) seeks feedback on its net-zero standard for automakers until March 22. The EV sales slowdown makes it increasingly likely that many big companies will walk away. To make the task simpler, I assembled a timeline of highly anticipated updates or public consultations for voluntary net zero, carbon accounting, nature and circular economy standards from — both established guidance and emerging alternative frameworks.

Today, I am pleased to share a new article I have co-authored with Professor Jürgen Ernstberger and Professor Gunther Friedl, both from Technical University of Munich, titled "How Carbon Accounting Supports Corporate Decarbonization." Our work, now published in Foundations and Trends in Accounting's special issue on Perspectives on Carbon Accounting and Reporting, explores how transactional carbon accounting can power more effective corporate decarbonization. As businesses face mounting pressure to reduce their carbon footprint, we propose leveraging traditional financial management systems as a robust foundation, not only to track emissions across Scopes 1, 2, and 3, but to allocate them precisely to products and services via product carbon footprints (PCFs). This level of granularity is critical to support decision-useful insights and transparent reporting across value chains. By integrating PCFs into ERP systems like SAP S/4HANA, companies can assess and manage emissions at the transaction and product level, linking environmental data with financial metrics. This enables the path to a Green Ledger, where carbon is treated with the same rigor as money in corporate decision-making. At SAP, this approach reflects our commitment to embed PCFs into core enterprise systems and elevate them as a strategic lever for both compliance and transformation. This method not only enhances internal steering and external accountability, but it also aligns with emerging regulatory frameworks such as the EU CSRD and SEC climate-related disclosures. Many thanks to my esteemed co-authors for their collaboration.

Net-zero has become the headline every company wants. But the authenticity of those commitments' rests on a credibility gap that’s widening fast. Carbon accounting, the backbone of climate disclosure, isn’t keeping pace. Standards are fragmented, supplier data is unreliable, and the gaps are widening. Deloitte found that 46% of FTSE-100 companies had to restate their sustainability disclosures, with nearly 9 in 10 tied to emissions data. It’s a signal for a strategic blind spot. If the numbers don’t hold, neither do the promises. If carbon data lacks integrity, leaders are steering multi-billion-dollar strategies with unreliable instruments. It can and will lead to regulatory penalties, investor skepticism, and reputational damage that can erase years of progress and customer trust. This is where leaders need to reset their priorities. Net-zero strategies are meaningless if the data can’t withstand scrutiny. Carbon data must be treated with the same discipline and auditability as financial data. That means investing in end-to-end traceability, standardizing methodologies across supply chains, and building rigorous verification systems. The future of net-zero won’t be written by the companies with the boldest targets. It will be decided by those whose numbers can stand up to the test. Those who embed accuracy, transparency, and trust into their carbon accounting will define which companies and which leaders are still standing when scrutiny sharpens. #CarbonAccounting #SustainableBusiness #RiskManagement #CorporateSustainability #SupplyChainCompliance
