Department of Defense

The Department of Defense reported total emissions of approximately 54.77 billion kg CO2e in 2019. This follows approximately 55.41 billion kg CO2e in 2018, and approximately 58.39 billion kg CO2e in 2017. Emissions have consistently decreased since 2010, when they were approximately 76.52 billion kg CO2e. The available data does not specify Scope 1, Scope 2, or Scope 3 breakdowns.

The Department of Defense has set various climate commitments. They aim to achieve net-zero Scope 1 and Scope 2 emissions by 2050, through initiatives such as transitioning to alternative fuel and electric vehicles. The Army Reserve specifically targets 100% Zero-Emission Vehicle (ZEV) acquisitions by fiscal year 2027 for both Scope 1 and Scope 2 emissions. Additionally, the Department is committed to achieving net-zero emissions across its portfolio of buildings, campuses, and installations by 2045, covering all scopes. In terms of intensity, the Department achieved a 20.9% energy intensity reduction from a 2003 baseline to 2021 for Scope 1 and Scope 2. For near-term absolute reductions, specific initiatives at locations like Joint Base Lewis-McChord aim to reduce traffic congestion and air emissions (Scope 1) by 85% by 2025, and stationary source air emissions (Scope 2) by 85% by 2025, from a 2020 baseline.
