EU Locks In 90% Emissions Cut by 2040: Ambition, Contradictions, and What It Means for the Planet

The European Union has taken one of its most significant steps yet in the fight against climate change. EU member states gave final approval this week to a legally binding target to cut greenhouse-gas emissions by 90% by 2040 compared to 1990 levels — a milestone that sets the trajectory toward the bloc’s 2050 net-zero goal and sends a long-term signal to businesses, investors, and trading partners worldwide.

Yet the same week that delivered this landmark environmental policy achievement also brought a series of developments that complicate the picture: weakened corporate accountability rules, a faltering global fossil-fuel exit agreement at COP30, and a major hydrogen project shelved by one of the world’s largest oil companies. Taken together, they illustrate the uneven, often contradictory pace of the energy transition in 2025.

A Strong Climate Target — With a Notable Asterisk

The 90% emissions-reduction target is not symbolic. It is legally significant, meaning EU institutions and member states are now bound to align policies — from renewable energy deployment to industrial transformation — with this trajectory. For sectors like steel, cement, transport, and agriculture, the message is clear: deep decarbonisation is no longer optional.

But in the same legislative cycle, EU countries also approved a substantial scaling back of the Corporate Sustainability Due Diligence Directive (CSDDD), reducing obligations for companies to assess environmental and human-rights risks across their supply chains. The move, driven by business lobbying and pressure from several member governments, has drawn sharp criticism from environmental and human-rights organisations who argue it undermines the very accountability frameworks needed to make ambitious targets credible.

The contradiction is hard to ignore: setting a bold 2040 climate goal while simultaneously reducing corporate responsibility for pollution, biodiversity loss, and labour abuses in global supply chains sends a mixed signal — to markets, to civil society, and to international partners watching Europe’s commitment to environmental policy.

COP30 and the Global Fossil-Fuel Fault Line

On the international stage, climate negotiations at COP30 in Brazil are proving equally fraught. According to Reuters, the latest draft agreement has dropped an earlier proposal for a global fossil-fuel exit — a clause that had been seen as a potential breakthrough following COP28’s historic language on “transitioning away” from fossil fuels. Talks are expected to extend into the weekend, reflecting deep divisions between major emitting nations, fossil-fuel producers, and climate-vulnerable countries.

There is, however, a meaningful signal from China. Beijing announced plans to cut its carbon intensity by 17% during its current five-year plan — a faster pace than the previous 2020–2025 period. While carbon intensity targets differ from absolute emissions cuts, the acceleration matters: China remains the world’s largest emitter, and its policy direction has outsized consequences for global conservation efforts, air pollution reduction, and the overall feasibility of limiting warming to 1.5°C.

When Business Reality Slows the Energy Transition

Perhaps the most telling development of the week came from the private sector. Exxon Mobil halted plans for what would have been one of the world’s largest green hydrogen production facilities, citing weak customer demand. The decision is a reminder that renewable energy and clean-technology investments — however essential — do not scale on ambition alone. They require stable policy frameworks, reliable offtake agreements, and market conditions that make capital commitment viable.

Hydrogen has been central to Europe’s industrial decarbonisation strategy, particularly for hard-to-abate sectors. Exxon’s withdrawal underscores a recurring tension in the energy transition: the gap between long-term climate targets and the short- to medium-term investment signals that actually move capital.

What This Means for Citizens, Businesses, and Policymakers

For European citizens and decision-makers, this week’s developments carry several practical implications:

• Businesses now have greater long-term certainty on the EU’s climate direction — but less regulatory pressure on supply-chain transparency, at least for now.
• Investors in clean energy and low-carbon infrastructure have a stronger policy anchor in the 2040 target, but demand-side risks remain real, as the hydrogen case illustrates.
• Policymakers face growing pressure to close the gap between headline targets and implementation — on corporate accountability, on fossil-fuel phase-out, and on creating the market conditions that make clean investment attractive.

The key takeaway: Europe’s 90% emissions-cut target is a genuine and important commitment. But climate ambition is only as credible as the policies, rules, and investments that back it up. This week showed both what is possible — and how much work remains.
