The document summarizes the new Low Emission Bus (LEB) Scheme introduced by the Office of Low Emission Vehicles (OLEV) to increase the uptake of low and ultra-low emission buses in England and Wales from 2015 to 2020. The LEB Scheme will provide £30 million in grants to support the purchase of accredited low emission buses and associated infrastructure. Bids for funding will be assessed based on their ambition, deliverability, impact on air quality, and value for money. To qualify for grants, bus manufacturers must certify that vehicles meet emissions reduction targets through testing and certification.
