Vehicle rental and leasing firms have pledged to increase their fleet of plug-in vehicles from the current 50,000 to 720,000 by 2025.
The commitment was made by the British Vehicle Rental and Leasing Association (BVRLA) on behalf of its 900 members.
The sector is responsible for one in eight cars on UK roads, according to the trade body, and will therefore play a vital role in efforts to lower vehicle emissions.
