Department of Defense

The Department of Defense reported total emissions of approximately 54.77 billion kg CO2e in 2019. This follows previous years with emissions of about 55.41 billion kg CO2e in 2018, 58.39 billion kg CO2e in 2017, and 59.31 billion kg CO2e in 2016. In 2015, total emissions were approximately 62.60 billion kg CO2e, and in 2014, they were about 61.88 billion kg CO2e. Earlier data shows emissions of around 63.60 billion kg CO2e in 2013, 69.33 billion kg CO2e in 2012, 74.43 billion kg CO2e in 2011, and 76.52 billion kg CO2e in 2010. The available data does not specify the breakdown of Scope 1, Scope 2, or Scope 3 emissions for these years, but notes missing data points for all scopes, as well as for Scope 3 categories such as purchased goods and services, business travel, and employee commute.

The Department of Defense has several climate commitments. It aims to achieve 100% Zero Emission Vehicle (ZEV) acquisitions for the Army Reserve by fiscal year 2027, covering both Scope 1 and Scope 2 emissions. The Department is also committed to achieving net-zero emissions across its portfolio of buildings, campuses, and installations by 2045, encompassing all scopes. Furthermore, a strategy is in place to transition gas-dedicated vehicles to low greenhouse gas (LGHG), alternative fuel, and electric vehicles, with a long-term net-zero goal for Scope 1 and Scope 2 emissions by 2050. The Department has already achieved a 20.9% energy intensity reduction from 2003 to 2021 for both Scope 1 and Scope 2 emissions. Additionally, there are near-term absolute targets to reduce traffic congestion and air emissions (Scope 1) by 85% by 2025 and to reduce stationary source air emissions (Scope 2) by 85% by 2025, starting from 2020.
