The U.S. military’s emissions are greater than many countries, its twelve-digit annual expenditures greater than most countries, and it is the largest energy user in the United States. It is also a huge investor in advanced energy research, a significantly growing user of renewables, and per the U.S. Department of Energy the Defense Department has seen energy usage fall almost 50% since 1975.

U.S. Senator and Presidential Candidate Elizabeth Warren (D-Massachusetts), and Representative Veronica Escobar (D), have introduced the Department of Defense Climate Resiliency and Readiness Act (pdf). The broader purpose of the document (section by section summary – pdf) is to use to heft of the military to drive clean energy adoption, while also readying the U.S. Military for future environmental shifts that will affect readiness.

The meat of the legislation requires the Defense of Department (DoD) to achieve net zero energy, in the aggregate, by ‘non-operational’ (fixed military infrastructure not supporting combat operations, or combat vehicles) assets globally by 2030. Within a year, a written strategy to meet this goal must be submitted, and every two years thereafter a progress report on meeting said goals must be submitted.

The document also makes quickly escalating appropriations for the research, development, and demonstration programs for microgrids and electric grid energy storage of:

2020 – $10 million

2021 – $25 million

2022 – $50 million

2023 – $75 million

2024 – $125 million

2025 – $200 million

2026-2030 – $250 million annually

The microgrid R&D program must prioritize integrating renewable energy sources, such as wind, solar, and hydropower; additive manufacturing; energy storage; location generation of zero-carbon fuels; developing and using fuel-efficient engines; empirical and science-based industry standards – within a broader umbrella of increasing the DoD’s readiness.

Planning, budgeting, procurement, and reporting processes dominate the rest of the document.

The annual DoD budget would be required to include, “a stream of dedicated funds for adapting to, and mitigating, climate change related risks to military networks, systems, installations, facilities, and other assets and capabilities.” It would also be required that the DoD report the effects on military readiness and an estimate of the financial costs reasonably attributed to climate change-related events over the preceding year, such as DoD actions to mitigate the effects of:

Extreme weather

Rising sea tides

Increased flooding

Drought

Desertification

Wildfires

Thawing permafrost

Annually, the DoD will be required to list the ten military bases within each service that emit the most carbon, an estimate of all energy consumption by the Defense Department, including greenhouse gas emissions, and an assessment of greenhouse gas emissions at all military bases, separated by operational sources and non-operational sources.

Contractors working with the DoD will also be required to report on their emissions, their climate risks, whether or not they are net zero, and – if not – then those contractors must pay a 1% fee on their bids which will be pooled into a newly created Energy and Climate Resiliency Fund which can only be used for improvements that adapt military networks, systems, installations, facilities, and other assets and capabilities to climate change.
