The U.S. Environmental Protection Agency (EPA) released its final state implementation plan (SIP) Requirements Rule for implementing the 2015 National Ambient Air Quality Standard (NAAQS) for ground-level ozone. These requirements apply to states and tribes with nonattainment areas as well as the 13 northeastern states that currently comprise the Ozone Transport Region. This rule will assist our state and tribal partners in developing their implementation plans to meet the 2015 ozone standards, while providing the greatest flexibility possible.

When the phone rang at 5 a.m., Graham Tapley felt the bottom of his stomach drop.

Urban planning decisions from decades past are likely a contributing factor to the rise of right-wing populism, a study from the University of Waterloo has found.

Labour abuses, including modern slavery, are ‘hidden subsidies’ that allow distant-water fishing fleets to remain profitable and promote overfishing, new research from the University of Western Australia and the Sea Around Us initiative at the University of British Columbia has found.

We’ve heard it ad nauseum from our political leaders and the media: We can’t do anything about climate change because it would cost us jobs and jeopardize our future.

Two highly motivated academics – Professors Gail Fraser, in the Faculty of Environmental Studies at York University, and Angela Carter, a political scientist at the University of Waterloo – joined forces to press for changes in the offshore oil industry after their study showed that a lack of regulatory action places seabirds’ lives at risk due to their attraction to lighting on oil rigs.

The ozone hole that forms in the upper atmosphere over Antarctica each September was slightly above average size in 2018, NOAA and NASA scientists reported today.

A new study of the Deepwater Horizon response showed that massive quantities of chemically engineered dispersants injected at the wellhead—roughly 1,500 meters (4,921 feet) beneath the surface—were unrelated to the formation of the massive Deepwater oil plume.

Humanity and the way we feed, fuel and finance our societies and economies is pushing nature and the services that power and sustain us to the brink, according to WWF’s Living Planet Report 2018. The report presents a sobering picture of the impact of human activity on the world’s wildlife, forests, oceans, rivers and climate, underlining the rapidly closing window for action and the urgent need for the global community to collectively rethink and redefine how we value, protect and restore nature.

Methane is a climate pollutant that leads to the production of ozone with serious health and environmental impacts
