In 2024, Boulder’s community-wide emissions decreased 8% from 2023 and were 29% below the 2018 baseline. Boulder has continued to reduce emissions since the adoption of its first Climate Action Plan in 2005.
The drop in community emissions was driven primarily by the cleaning of the grid and the reduction of energy usage (electricity and natural gas) in residential, commercial and industrial buildings. Emissions from vehicles also saw a sharp decline due to lower vehicle trips and increased adoption of electric vehicles.
Boulder’s largest emissions sources are electricity use, natural gas use, on-road transportation and aviation. This demonstrates the continued importance of moving away from fossil fuels and adopting cleaner sources to power the energy grid, such as solar and wind. Boulder must also accelerate the transition to efficient, electric technologies and cleaner modes of transportation.
