The US Army, led by Defense Secretary Lloyd Austin, having identified climate change as a top priority, launched a Climate Working Group in response to a January executive order signed by President Joe Biden.  As part of this initiative to respond to global warming and climate change as grave threats t0 national security the Army has adopted a plan to transition into using hybrid-drive, electric vehicles, tactical electric vehicles by 2035, and fully electric vehicles by 2050, according to its new Army Climate Strategy. Furthermore, it also aims to attain net-zero greenhouse emissions from all US Army procurements by 2050.

We will withhold judgment on the wisdom of the Army publishing its plans to defeat the enemy(Climate Change) in the open like this.

If it were treated as a country, the US military would rank 47th in global carbon emissions. A study done by Durham and Lancaster University revealed that the US military was “one of the largest climate polluters in history, consuming more liquid fuels and emitting more CO2e (carbon-dioxide equivalent) than most countries.”

Secretary of the Army Christine Wormuth expressed that there is no best time to tackle climate change head-on than the present. “The Army must adapt across our entire enterprise and purposefully pursue greenhouse gas mitigation strategies to reduce climate risks. If we do not take action now, across our installations, acquisition and logistics, and training, our options to mitigate these risks will become more constrained with each passing year,” she said in a statement.

With the US aware of its carbon footprint, it now wants to decrease its negative impact on climate change by going hybrid and electric to reduce its reliance on fossil fuel. First, its non-tactical vehicle fleet (NTV) will be modernized by slowly removing old NTVs and replacing them with hybrid vehicles. These vehicles include sedans, station wagons, utility vehicles, trucks, vans, and buses that the US Army utilizes.

Efforts have actually begun with over 18,000 NTVs removed and replaced by 3,000 hybrid vehicles in the last three years, saving the Army about 13 million gallons per year, said to reduce greenhouse gases emissions per mile by 12%, and above all, decreasing NTV fleet costs by over $50,000,000. After the transition has been done for NTVs, its tactical vehicles will be the next to transition, with the aim of having fully-electric tactical vehicles by 2050.

In line with these actions taken, the Army Materiel Command in 2021 had enacted a mandate which orders all vehicle leases and purchases must be all-electric. If no electric vehicles are commercially available, then hybrids must be purchased or leased. Conventional vehicles that use gas can only be used upon an approved exception—otherwise, vehicles that run on fossil fuel are not permitted.

The Army has also pursued strategic partnerships to develop prototypes of electric reconnaissance vehicles, with the first unit expected to be completed and tested by September 2023.
