THE BIG STORY

 

The EU Omnibus Directive Enters Into Force This Week — Here’s What Happens Now

On March 18, 2026, the EU’s Omnibus I Directive officially enters into force, marking the single largest rollback of sustainability regulation in European history. Published in the Official Journal on February 26 as Directive (EU) 2026/470, this is no longer a proposal. It is law.

The threshold has been raised to companies with more than 1,000 employees AND more than €450 million in net turnover. Both conditions must be met. The European Commission estimates around 80% of companies previously subject to CSRD reporting are now exempt. Mandatory datapoints have been cut from 1,073 to approximately 320.

For “Wave 2” companies — those originally due to report for FY 2025 — the obligation has been pushed back to FY 2027, with first reports due in 2028. Member States must transpose CSRD amendments into national law by March 19, 2027. The revised European Sustainability Reporting Standards are due from a Commission Delegated Act by September 18, 2026. The Omnibus also scaled back the CSDDD — compliance now required only from July 2029, with the harmonised EU civil liability regime removed.

Why it matters

The EU has gone from leading the world on mandatory sustainability disclosure to creating a two-tier system. But the market’s response tells a different story. LSEG launched a new ESG ratings framework covering 16,000 companies this same week — using 220 standardised indicators and a 0–5 scale across 12 themes including climate transition and biodiversity. Capital markets are building their own data infrastructure regardless of what Brussels requires.

And here’s the counter-signal regulators didn’t expect: an osapiens survey of 403 senior decision-makers found that 90% of companies no longer in CSRD scope plan to maintain or expand their sustainability reporting anyway. 86% say they can continue at CSRD-equivalent standards. The driver has shifted from compliance to investor and customer demand.

Monday morning action

Check whether your company still falls within the revised CSRD scope — you need more than 1,000 employees AND more than €450 million in net turnover (both required, no balance sheet test). If you’re newly out of scope, don’t stop preparing — LSEG, MSCI, and the EU’s incoming ESG Rating Regulation (effective July 2, 2026) will still demand comparable data.

AI x SUSTAINABILITY

 

The Iran Energy Shock Just Made AI’s Carbon Problem Worse

Oil has surged past $100 per barrel for the first time since 2022, driven by the US-Israel war on Iran. The IEA called it the “biggest oil supply disruption in history” — roughly 8 million barrels per day removed from global supply. Strait of Hormuz shipping has dropped roughly 90%. UK gas prices have doubled. Thirty-two countries released 400 million barrels of emergency stockpiles — the largest coordinated release ever.

For AI infrastructure, the timing is brutal. Data centres running on grid electricity in gas-dependent regions are watching their operating costs explode. Companies with long-term renewable PPAs are suddenly sitting on a competitive moat. The strongest argument for clean energy infrastructure just shifted from climate obligation to economic survival.

Sustainability angle: Every Scope 2 emissions calculation just changed. If your company’s AI or cloud strategy depends on grid electricity, your emissions trajectory and your cost trajectory are both moving in the wrong direction.

EIA Warns Data Centre Boom Will Increase US Fossil Fuel Generation

The US Energy Information Administration projected US electricity demand will hit record highs of 4,260 billion kWh in 2026 and 4,388 billion kWh in 2027, driven largely by AI data centres. The critical detail: a 7.3% increase in natural gas-fired generation between 2025 and 2027 in its high data centre growth scenario, compared with 1.7% under baseline forecasts. Against $100+ oil and the Iran supply shock, those gas-dependent projections look even more precarious.

REGULATORY & POLICY

 

Trump Administration Sues California Over Vehicle Emissions Standards

What changed: Federal government directly challenging state-level climate authority through litigation, following the EPA’s February 12 repeal of the Endangerment Finding

Who’s affected: Automakers in California and the 17 states following its emissions standards

Key date: March 12, 2026 (filed)

What to do: Scenario-plan for a fragmented US regulatory landscape. California will fight this.

EU Bans Offset-Based “Carbon Neutral” Marketing Claims From September

What changed: First EU directive to explicitly prohibit offset-based environmental marketing claims

Who’s affected: Any company marketing to EU consumers, regardless of domicile

Key date: September 27, 2026 — rules take effect

What to do: Audit every consumer-facing environmental claim. Any claim relying on carbon credits for “neutrality” must be restructured or withdrawn.

Singapore Sets Climate Risk Expectations for Financial Institutions

What changed: APAC’s benchmark regulator sets supervisory expectations on climate transition planning — with an explicit engagement-over-divestment principle

Who’s affected: All banks, insurers, and asset managers supervised by MAS

Key date: September 2027 (effective after 18-month transition)

What to do: If you have Singapore operations or investors, align your climate risk management with MAS expectations.

Apple Wins Greenwashing Lawsuit — But the Rules Are Changing

A US federal judge dismissed a class-action lawsuit against Apple’s “carbon neutral” marketing claims for its Apple Watch on February 20. Judge Noël Wise ruled the plaintiffs failed to plausibly allege the claims were false. Apple says it reduced lifecycle emissions by over 60% since 2015, with remaining emissions offset through forest conservation projects.

But the legal win may be short-lived. The EU’s ECGT Directive (see above) would prohibit exactly the kind of offset-based “carbon neutral” claims Apple has made — for EU consumers from September. US courts give companies the benefit of the doubt on environmental marketing. EU regulators ban offset-based claims outright.

MARTIN’S TAKE

 

Something happened this week that tells you more about the future of sustainability than any directive or court ruling.

The EU’s Omnibus entered into force, exempting roughly 80% of companies from mandatory reporting. Days earlier, LSEG launched ESG ratings covering 16,000 companies. And when osapiens surveyed companies that just lost their reporting obligation, 90% said they’d keep reporting anyway.

The lesson is clear: regulation is no longer leading the sustainability market. It’s following it. The investors, lenders, and supply chain partners who need ESG data haven’t stopped needing it because Brussels changed a threshold. If anything, the Omnibus concentrated their attention on the data that matters — while the companies outside mandatory scope discovered that their customers and capital providers still expect exactly what the regulation used to require.

Meanwhile, oil at $100 is doing more for the energy transition business case than a decade of climate policy. Every company reviewing its energy procurement this week isn’t doing it because of CSRD. They’re doing it because their electricity bill just doubled.

The companies that will lead from here are the ones that stopped treating sustainability reporting as a compliance exercise years ago. For everyone else, the Omnibus offered a convenient off-ramp. The market didn’t take it.

“The strongest regulatory signal this week didn’t come from Brussels. It came from a ratings agency, a survey, and an oil price.”
