U.S. Navy climate plan calls to curb emissions, electrify vehicle fleet

The U.S. Navy on Tuesday unveiled a climate action plan focused on installing cyber-secure microgrids, boosting its supply of lithium batteries and slashing planet-warming greenhouse gas emissions.

The Navy’s strategy, a response to President Joe Biden’s executive order calling on federal agencies to develop plans to adapt to climate change, directs the service to achieve a 65% reduction in greenhouse gases by 2030 and net-zero emissions by 2050.

The plan comes after the U.S. Army in February unveiled its first climate strategy, which primarily focused on protecting and training soldiers amid worsening climate disasters such as floods and heat waves.

The Department of Defense warned last year that climate change poses a critical threat to U.S. military operations, and that more frequent and intense weather events have already cost the department billions of dollars.
