Clean air at risk in United States

July 2026

Air pollutants, measured as ozone and particulate matter, cause more than 100,000 premature deaths each year in the United States and affect the health of millions of people. In a controversial move, Lee Zeldin, administrator of the United States.

Environmental Protection Agency (EPA), announced that the agency will no longer consider these health costs when drafting new regulations.

Democratic lawmakers have strongly opposed the change. The following week, members of the United States Congress sent a letter to the EPA warning that ignoring health benefits when setting air quality standards could lead to weaker protections.

“That EPA may no longer monetize health benefits when setting new clean air standards does not mean that those health benefits don’t exist,” the letter reads. “It just means that you will ignore them and reject safer standards, in favor of protecting corporate interests.

Campaign to weaken EU methane rules gathers pace

The EU Methane Regulation (EUMR) has come under mounting political pressure in recent months. Following an intensive lobbying campaign by the US government, Qatar and the fossil fuel industry, several member states have called for delays or changes to its implementation. So far, however, the European Commission has refused to reopen the legislation.

Air quality in the EU is improving

Air pollution across Europe continues to decline. However, a large majority—94%—of the urban population still lives in areas where levels of fine particulate matter (PM2.5) exceed the World Health Organization (WHO) guideline values. PM2.5 is considered the air pollutant most harmful to human health.

Europe issues first joint roadmap for seagrass restoration

More than 50 scientists from 17 European countries have published the first continent-wide recommendations for protecting and restoring seagrass meadows. Developed by the European Seagrass Restoration Alliance (ESRA), the guidance outlines eight priority actions to help reverse decades of habitat loss and support implementation of the EU Nature Restoration Regulation.
