The Office of Environmental and Energy Coordination (OEEC) has released the 2025 Climate Action Progress and Highlights Report, documenting another year of significant gains toward reducing greenhouse gas emissions and building a more climate-resilient Fairfax County.
The report outlines progress across county operations and the broader community, including major steps forward in clean energy, sustainable development, climate-ready infrastructure, and support for residents most vulnerable to the impacts of “warmer, wetter and weirder” weather.
While overall greenhouse gas emissions in Fairfax County have decreased by 4.2 million metric tons, or 28%, since 2005, emissions rose slightly between 2020 and 2023, according to the latest inventory from the Metropolitan Washington Council of Governments. This uptick is largely due to vehicle travel bouncing back from the reduced levels seen during the 2020 pandemic.
“Despite a challenging policy and funding environment at the federal and state levels, Fairfax County continues to move forward on climate action,” said OEEC Director John Morrill. “The progress we’ve made is the product of strong partnerships across county agencies and alongside community organizations, businesses, and residents.”
