The Difference of the One and the Many

Why the Repeal of the US Endangerment Finding Needs a Fast Response

Dipl.-Ing.(TU) Werner P. Bauer

In February 2026, the US government took a step with far-reaching consequences: the Environmental Protection Agency (EPA) repealed the 2009 Endangerment Finding, the science-based determination that greenhouse gases such as carbon dioxide and methane pose a threat to public health and well-being and must therefore be regulated. This decision removes the legal and scientific foundation for nearly all US climate regulations – from emission standards for vehicles, power plants, and industrial facilities to methane requirements for landfills and oil and gas infrastructure.

Despite the historic significance of this measure, the international response has been remarkably muted. Although scientific and civil society actors have voiced criticism, there has been little opposition from states themselves, with China being the only exception.

What does the repeal mean in concrete terms – and why does it directly affect waste management in the United States?

The Endangerment Finding was not only a legal foundation, but also a symbol: it represented the commitment of the world's largest economy to regulate greenhouse gas emissions. Its repeal means that:

• the EPA is no longer required to regulate greenhouse gases;
• all climate regulations under the Clean Air Act lose their legal stability and can be reversed; and
• the US can avoid any form of greenhouse gas regulation in the future without being held accountable.

The consequences are particularly serious for waste management, both nationally and globally. Without regulatory requirements:

• there is no obligation to reduce emissions from landfills, which are among the world's largest sources of methane, or to limit other emissions from waste treatment processes; and
• there is a lack of transparency regarding emissions data, which was previously generated through EPA reporting.

Despite political fluctuations, the US has been a key player in the Global Methane Pledge, which aims to reduce global methane emissions by 30% by 2030. If the largest economy in the world erases the scientific basis of its climate policy, the agreement loses credibility — and thus effectiveness.

Why has the international community remained so silent?

The muted response from international politicians is surprising, but not inexplicable. Although the EU is pursuing ambitious climate targets, it has itself made numerous concessions in 2025 and 2026 – including opening up to international offsetting, reducing reporting requirements, and delaying the implementation of key Green Deal instruments.

An analysis of the European Green Deal rollback also shows that, in view of geopolitical and economic upheavals, many member states have long been prepared to restrict environmental and climate protection in favour of competitiveness.

Might some governments feel more relief than alarm as the US – once again – withdraws from global climate policy? It remains to be seen to what extent other countries will stand their ground and continue to base their goals, measures, and laws on scientific and research findings in the future.

What does this global shift mean for the waste sector?

The repeal of the US Endangerment Finding is more than just an internal US deregulation project. It

• removes the scientific basis for climate-oriented waste policy,
• eliminates key regulatory instruments for greenhouse gases,
• undermines political pressure to reduce methane, and
• slows down innovation and progress in waste management – worldwide.

This ‘return to arbitrary climate policymaking’ thus threatens key advances in an industry whose solutions – from landfill gas extraction and recycling to the development of WtE structures – are crucial to achieving global climate targets.

For waste management, standards for refuse collection vehicles and incentives for modern, low-emission fleets would effectively be removed, resulting in higher emissions and less innovation in logistics solutions for the circular economy.

Even more than in traditional waste management, the goals and measures of the circular economy are shaped by cultural, political, and structural factors.
The EPA’s decision shows that political narratives can override scientific evidence overnight. As cultural barriers and misperceptions can quickly take hold, it is essential to emphasise social values, which often have a greater impact on waste management than technologies or regulations.

WasteCulture calls for action to close emerging gaps now

When scientific principles are called into question, it is important to emphasise and consolidate the significance of independent findings. The founders of WasteCulture call on stakeholders in waste management, science, civil society, and politics to:

• highlight case studies from waste management practice that have been developed on the basis of scientific findings;
• jointly advocate a position that recognises climate protection in conjunction with waste management and the circular economy as a key measure to address the global crises;
• actively support the restructuring of international agreements such as the Global Methane Pledge (GMP) and work towards the reform of GMP member states. The institutional framework should be robust enough to continue operating with 158 participating countries without the US, and even see this as an opportunity to reach decisions more quickly;
• openly defend the value of science-based policy and practice;
• and repeatedly affirm cultural values.

Silence is not an option – face what is, don’t look away

The repeal of the Endangerment Finding undermines the crucial scientific foundation and the key reference point for global climate policy, and, unless it is clearly opposed, risks damaging its credibility at its core. Without a broad and unambiguous response, we risk allowing this step back to become normalised in the short to medium term.

Climate policy depends not only on laws, but also on attitude. We are convinced that you know best where and how you can put this attitude into practice.
