EU REPORTING FRAMEWORKS

Europe flirts with ditching its own reporting standards for ISSB

In a surprise move, the European Commission is considering replacing ESRS with the ISSB’s global baseline standards—a potential earthquake for thousands of companies currently building CSRD reporting strategies.

  • What’s at stake: ISSB uses single (financial) materiality; ESRS requires double materiality covering impacts on people and planet. ISSB Chair Emmanuel Faber proposed a compromise: use ISSB for financial reporting and top up with GRI for broader impacts
  • The politics: German MEPs back the switch. A French business group calls it “fuzzy” and warns it could make reports more complicated, not less
  • Timeline: New EFRAG Chair Kerstin Lopatta takes over May 1. She inherits this decision on top of the Omnibus I simplification that already exempted approximately 80% of companies from CSRD reporting requirements
CARBON BORDER POLICY

Europe’s carbon border tax goes live at €75.36 per tonne

The EU published its first-ever CBAM certificate price this week, setting Q1 2026 at €75.36 per metric tonne of CO₂e. But the real story is in the details.

  • The data gap problem: Importers without verified emissions data must use default values — which assume worst-case emissions. A highly efficient steel plant in India or Brazil gets treated like the dirtiest facility in its region. Those defaults rise by 10% in 2026 and 30% by 2028
  • UK following suit: The UK released draft CBAM regulations targeting January 2027, designed to be interoperable with the EU system; consultation runs until May 21
  • Bottom line: If your supply chain touches CBAM-covered products—steel, aluminum, cement, fertilizers, electricity—verified emissions data just became a competitive advantage, not just a compliance box
CARBON MARKETS

Microsoft hits pause on carbon removal—and the market shudders

Microsoft — which has purchased more than 70 million tonnes of carbon removal since 2020, roughly 90% of the entire market — told suppliers this week that it is pausing future purchases. The move sent shockwaves through the nascent carbon removal industry.

  • Scale of impact: Microsoft bought 40 times more carbon removal than any other buyer or coalition. Without its demand, startups from direct air capture to biochar face an existential funding gap
  • The walkback: CSO Melanie Nakagawa said the company may “adjust the pace or volume” of procurement but insisted the program has not ended and ambitions remain unchanged
  • Why it matters: If the world’s biggest corporate climate spender can go wobbly, it raises hard questions about whether voluntary markets alone can scale carbon removal to the levels needed. MIT Technology Review called it a “pivotal moment” for the industry
ENVIRONMENTAL STANDARDS

ISO 14001 gets its biggest update in a decade

The world’s most widely used environmental management standard just received a major overhaul, and for 670,000-plus certified organizations, the clock is ticking.
  • What’s new: Life cycle perspective is now required in EMS scope; stronger emphasis on climate change, biodiversity, and resource efficiency; new change management requirements for planned changes affecting EMS outcomes
  • Transition window: Three years to comply—all ISO 14001:2015 certificates must transition by May 2029
  • Why it matters: Research links ISO 14001 adoption directly to improved environmental performance and emissions reductions. The new edition is designed to be “smoother to implement”, particularly for smaller organizations
CORPORATE CLIMATE COMMITMENTS

Delta walks back climate targets—net zero now just an “aspiration”

  • The reason: Delta cited slow SAF development and limited supply—a fair point, but one conveniently timed with the broader corporate trend of quietly softening climate language
  • Pattern recognition: Delta joins a growing list of companies recalibrating climate pledges. When a net-zero commitment becomes an “aspiration,” it’s the corporate equivalent of “we should get lunch sometime”
  • Silver lining: Delta still describes SAF as the most important decarbonization lever for aviation. The targets may be gone, but the direction of travel hasn’t changed—it’s just slower than promised

Corporate climate action

SBTi Trend Tracker: Validated net-zero targets grew 40% in 2025, with Asia driving 53% of new growth. Japan leads with 2,091 companies—more than the U.S. at 943.

Standards and reporting

ISO and GHG Protocol announced a new working group for product-level GHG accounting to create globally consistent product carbon footprint measurement—a key enabler for CBAMs worldwide. Webinar scheduled for April 24.

Sustainable finance

Canada launched its Sustainable Finance Taxonomy Council with 17 members tasked with defining “green” and “transition” criteria for six sectors by 2027. The country needs an additional $115 billion per year in green investment.

Policy & politics

U.S. Treasury Secretary Scott Bessent called climate change an “elite belief” at the World Bank spring meetings, pushing to redirect lending away from climate finance toward critical minerals and fossil fuels.

Energy transition

Solar panel sales surged 50% across Europe as the Iran conflict pushed Brent crude past $116 per barrel. Heat pump and EV inquiries also spiked.

Science

New research in Nature Communications Earth & Environment found the Gulf Stream has shifted approximately 50 kilometers north over 30 years—a pattern that preceded AMOC collapse in simulations. The 25-year warning window before collapse could shrink to “almost nothing” under accelerated warming.

Frequently asked questions

It would represent a fundamental shift in the philosophy of European climate disclosure. ESRS requires double materiality—companies must report both on how climate affects the business (financial materiality) and how the business affects the climate and society (impact materiality). ISSB uses only financial materiality, meaning impacts on people and planet are only reported if they affect enterprise value. Replacing ESRS with ISSB would significantly narrow the scope of what European companies disclose and would effectively align EU requirements with the global ISSB baseline already adopted in the UK, Japan, Australia, and elsewhere. For companies with established CSRD reporting strategies, this creates real uncertainty about which standard to build to.

The EU Carbon Border Adjustment Mechanism (CBAM) is a carbon tariff on imports of carbon-intensive goods entering the EU—currently covering steel, aluminum, cement, fertilizers, electricity, and hydrogen. The €75.36 per tonne price is based on Q1 2026 EU Emissions Trading System allowance auction results and represents the price importers will pay per tonne of embedded emissions starting February 2027. Companies without verified supplier emissions data will be assigned default values that assume worst-case emissions—creating a direct financial incentive to invest in accurate Scope 3 supply chain data now. The UK’s parallel CBAM, targeting January 2027, adds further urgency for companies with UK exposure.

Microsoft’s pause is significant because it exposes the fragility of voluntary carbon removal markets when a single buyer represents roughly 90% of demand. For companies that have incorporated future carbon removal into their net-zero pathways, it raises practical questions about supply availability, pricing stability, and the long-term viability of removal as a compliance strategy. It also reinforces the priority of actual emissions reductions—via energy efficiency, renewable procurement, and supply chain decarbonization—over removal-dependent net-zero architectures. Removal has a role in reaching net zero, but the Microsoft situation illustrates why it cannot be the primary lever.

ISO 14001:2026 is the first major revision to the world’s most widely adopted environmental management standard since 2015. Key changes include a requirement to incorporate a life cycle perspective into the EMS scope, stronger emphasis on climate change, biodiversity, and resource efficiency as part of environmental context, and new change management requirements for planned changes affecting EMS outcomes. Organizations currently certified to ISO 14001:2015 have until May 2029 to transition. Recertification is required—companies should begin gap assessments now, particularly those with complex supply chains or significant Scope 3 reporting obligations.

Beyond the reputational dimension, the downgrade has direct implications for supply chain sustainability. Delta is a CDP Supply Chain Member, meaning its suppliers are subject to requests for emissions data and sustainability performance. Companies that have built supplier relationships or ESG positioning around Delta’s stated climate commitments should monitor whether the weaker language translates into reduced rigor in supplier requirements. More broadly, the trend of companies softening climate language increases the importance of verified, third-party-assured emissions data over voluntary pledges—both for companies managing their own credibility and for those assessing supply chain climate risk.

The new ISO and GHG Protocol working group on product carbon footprint measurement is directly relevant to CBAM compliance. CBAM requires importers to report and verify the embedded carbon content of specific products—which requires a standardized, globally consistent methodology for calculating product-level emissions. Without that, companies face the risk of using default values that systematically overstate emissions and increase their CBAM liability. A jointly developed ISO-GHG Protocol product carbon footprint standard would provide the credible, internationally recognized methodology that both regulators and auditors require for verified product-level disclosure.
