Climate & Environmental Regulation
The EU Green Deal has reshaped environmental law into a binding decarbonisation framework. With 12+ major legislative acts now in force or adopted, climate compliance spans every sector -- from carbon pricing and methane limits to nature restoration and mandatory disclosure.
The European Union has turned its climate ambitions into binding law. Under the European Green Deal, the EU must cut greenhouse gas emissions by at least 55% by 2030 (compared to 1990 levels) and reach net-zero emissions by 2050. These are not aspirations -- they are legal obligations written into the EU Climate Law. In April 2026, a 90% net reduction target for 2040 was formally added to the same law.
To meet these targets, the EU adopted a package of over a dozen laws known as "Fit for 55." These laws touch nearly every part of the economy: energy companies must use more renewables, manufacturers face stricter pollution limits, importers pay a carbon border tax, and large companies must publicly report their environmental impact. A Social Climate Fund of up to EUR 86.7 billion will help households and small businesses manage the transition costs when the new emissions trading system for buildings and road transport (ETS 2) starts in 2027.
For businesses, new compliance obligations are arriving on a rolling basis. Some are already in force -- mandatory sustainability reporting under the CSRD and carbon pricing for heavy industry under the EU ETS. Others kick in over the next few years: the Carbon Border Adjustment Mechanism entered its definitive phase in January 2026 (with certificate purchases beginning in 2027), and ETS 2 for buildings and transport launches in 2027. Around 50,000 companies now fall under EU sustainability reporting rules alone.
This page tracks the full landscape of climate and environmental regulation in the EU and US -- the key laws, their current status, upcoming deadlines, and what they mean for different types of companies. Whether you run a factory, manage a supply chain, or work in finance, the rules covered here likely affect you.
Climate and environmental regulation has undergone a profound transformation in recent years, moving from a niche area of environmental law into a central pillar of corporate governance and financial regulation. The European Green Deal, launched in 2019, set the EU on a path to climate neutrality by 2050, and the European Climate Law made this target legally binding. In the United States, environmental regulation centres on the Environmental Protection Agency's authority under the Clean Air Act and Clean Water Act, supplemented by emerging climate disclosure requirements from the Securities and Exchange Commission.
The breadth of affected industries is staggering. Energy producers, manufacturers, transport operators, agricultural businesses, construction firms, and financial institutions all face overlapping environmental obligations. In the EU, the Fit for 55 legislative package introduced or strengthened more than a dozen regulations and directives aimed at reducing net greenhouse gas emissions by at least 55% by 2030. In the US, EPA regulations govern criteria pollutants, hazardous air pollutants, and greenhouse gas emissions from power plants, vehicles, and industrial facilities.
Key obligations vary by jurisdiction and sector but include emissions monitoring and reporting, compliance with emission limits or cap-and-trade schemes, energy efficiency requirements, waste management obligations, and increasingly, climate-related financial disclosures. The EU Emissions Trading System (ETS) is the world's largest carbon market, requiring covered installations to surrender allowances corresponding to their verified emissions. The Carbon Border Adjustment Mechanism (CBAM) extends carbon pricing to imports, preventing carbon leakage to jurisdictions with weaker climate policies.
Disclosure requirements are rapidly expanding. Under the CSRD and the EU Taxonomy Regulation, thousands of European companies must now report detailed climate and environmental data, including taxonomy-aligned activities and transition plans. The US SEC Climate Disclosure Rule, though subject to ongoing legal challenges, signals a similar direction by requiring publicly traded companies to disclose material climate-related risks, governance processes, and greenhouse gas emissions.
These regulations do not operate in isolation. The EU Taxonomy provides the definitional framework that underpins CSRD climate disclosures. The Renewable Energy Directive drives the energy transition, while REACH and RoHS address chemical and hazardous substance risks. For businesses, the convergence of climate, environmental, and financial regulation demands integrated strategies that align operational transformation with reporting obligations, investor expectations, and evolving legal requirements across jurisdictions.
