A new Biden administration directive instructs federal employees to prioritize making sustainable choices while on official travel.

The directive tells civil servants to rent electric vehicles on official travel when the cost of that vehicle is less than or equal to the most affordable comparable option.

It also directs them to use rail, rather than planes or cars, for trips of less than 250 miles if rail is an available and affordable option. Employees will also be expected to use public transportation when traveling locally.
