The European Central Bank (ECB) dropped a bold warning on May 7, 2025, about the European Commission’s plan to slash sustainability reporting rules for businesses. While the ECB is all for making life easier for companies, it says the Commission’s proposal to exempt 80% of firms from mandatory reporting under the Corporate Sustainability Reporting Directive (CSRD) could spell trouble for investors, the economy, and the EU’s green goals.

What’s the Big Deal?

The Commission’s Omnibus I package, rolled out in February 2025, wants to lighten the load on businesses by tweaking major regulations like the CSRD, Corporate Sustainability Due Diligence Directive, Taxonomy Regulation, and Carbon Border Adjustment Mechanism. The CSRD, meant to upgrade the old Non-Financial Reporting Directive, was set to make over 50,000 companies (up from 12,000) share detailed info on their environmental impact, human rights, and sustainability risks using new European Sustainability Reporting Standards (ESRS).

But the Omnibus plan flips this on its head. It suggests limiting CSRD reporting to only companies with over 1,000 employees and €50 million in revenue, kicking out 80% of the firms originally covered. It also aims to cut the number of data points in the ESRS, making reporting less detailed.

ECB’s Red Flags

The ECB gets the need to simplify, but it’s worried this goes too far.

“Reliable, standardized sustainability data is crucial,” the ECB stated, emphasizing that investors need this info to funnel money into green projects and price risks like climate change impacts.

Without it, bad investment calls could pile up, and the EU’s push for net-zero by 2050 could stall.

The ECB’s role in keeping banks stable and managing money also relies on this data. Climate risks—like floods or energy price spikes—can shake up the economy and banks, and the ECB needs solid info to stay ahead. Cutting 80% of companies from CSRD reporting could hide key details, especially since big polluters, like some fossil fuel firms, might slip through the cracks. Even smaller banks and companies, currently reporting under the old rules, could go dark, despite facing big ESG risks.

A Smarter Fix

Instead of slashing the CSRD to cover only 1,000-employee giants, the ECB suggests keeping companies with 500+ employees on the hook but giving them simpler, tailored reporting rules. This would balance the load for smaller firms while keeping vital data flowing. The ECB also nixed the Commission’s idea to make non-EU companies report more, warning it could put EU firms at a disadvantage and create data gaps.

The EU’s plan to let smaller companies report voluntarily sounds nice, but the ECB sees risks—like only the “good” firms opting in, or others cherry-picking data to look greener than they are. On the ESRS data cuts, the ECB wants to keep key climate and biodiversity metrics, crucial for understanding risks like storms or deforestation.

Why Sector Rules Matter?

The Commission’s decision to scrap sector-specific reporting standards got a side-eye from the ECB. These rules help compare companies in industries like energy or transport, showing who’s ready for the green shift. Without them, investors and banks lose clarity. The ECB suggests sector-specific guidelines to fill the gap, ensuring consistent reporting.

Why It Matters?

The EU’s green ambitions—think 55% emissions cuts by 2030—lean on businesses sharing clear sustainability data. Investors, with 83% demanding eco-friendly options per a 2024 PwC survey, need this to bet on the right companies. Weakening the CSRD could also spook markets, as banks and insurers rely on this data to dodge climate-related losses, estimated at €1 trillion by 2050 by the ECB.

What’s Next?

The ECB’s opinion is a loud nudge for the Commission to rethink its plan. Keeping more companies in the CSRD, with lighter rules for smaller ones, could save the EU’s green cred without overwhelming businesses. As the EU juggles growth and sustainability, this debate will shape how it tackles climate change and keeps investors in the loop.
