Abstract:

The global HDV fleet is projected to contribute more greenhouse gas emissions than the light-duty vehicle fleet by 2025.3 Zero-emission vehicle (ZEV) technology for HDVs, including battery electric vehicles and fuel-cell electric vehicles, has the potential to reduce significantly climate and air quality impacts, including in emerging markets and developing economies (EMDEs). This briefing focuses primarily on public transport, including bus electrification in EMDEs, while recognizing the opportunities to electrify other HDV segments with operational profiles similar to buses. Characteristics of those profiles, including predictable daily range, returnto-base operation, and long dwell time, are suited to depot charging, the charging practice commonly used by urban delivery vans, sanitation trucks, postal trucks, box trucks, and drayage trucks.
