Secretary of the Army Christine Wormuth testifies before the House Armed Services Committee about the FY2022 defense budget request in the Rayburn House Office Building on Capitol Hill, June 29, 2021 in Washington, DC.

The U.S. Army on Tuesday unveiled its first climate strategy focused on protecting and training soldiers amid worsening climate disasters like floods, heat waves and drought and cutting the service's greenhouse gas emissions.

The Army's plan, a response to President Joe Biden's executive orders calling on agencies to adapt to climate change, directs the service to slash its emissions in half from 2005 levels by 2030 and reach net-zero emissions by 2050.

As part of the strategy, the Army plans to install a microgrid on all of its installations by 2035 and have an fully electric non-tactical vehicle fleet by 2035. It will also work to cut emissions from buildings and include climate change threat mitigation into its land management decisions.

The service has already started or completed 950 renewable energy projects, including a 2.1 megawatt solar field at Fort Knox in Kentucky, and 25 microgrid projects scoped and planned through 2024, according to the strategy.

The Department of Defense warned last year that climate change poses a critical threat to U.S. military operations and will lead to new sources of global political conflict. Water shortages, for instance, could become a main source of conflict between U.S. military overseas and the countries where troops are based, according to the department.

A rise in extreme weather events has already cost the department billions of dollars and will prompt more demand for U.S. troops while damaging military bases, degrading mission capabilities and putting service members at risk.

"Climate change threatens America's security and is altering the geostrategic landscape as we know it," Army Secretary Christine Wormuth said in a statement.
