As the world races to discover solutions for reaching net zero carbon emissions, a PNNL analysis quantifies the economic value of the existing nuclear power fleet and its carbon-free energy contributions.

Methane emissions from coal mines are likely higher than previously calculated, largely due to emissions from abandoned mines.

Earth systems scientist Brian O’Neill has been named the new director of the Joint Global Change Research Institute. The institute is a partnership between PNNL and the University of Maryland in College Park, MD.

New open-source software mimics complex global hydrological models with extraordinary computational efficiency.

The vast reservoir of carbon stored beneath our feet is entering Earth's atmosphere at an increasing rate, according to a new study in the journal Nature.

Open-source tool helps connect high-resolution sectoral models and broader integrated human-Earth system models.
