The use of more new and clean energy vehicles is being encouraged in China's parcel delivery sector to reduce carbon emissions and promote green development, an official from the State Post Bureau said on Friday.

The goal for the parcel delivery and postal sector is to have 80 percent of new vehicles and replacements for old ones be new energy vehicles by 2025, said Lin Hu, deputy director of the bureau's market inspection department.

Regional postal regulators have also promoted the adoption of new energy vehicles in the sector, with the Shanghai Municipal Postal Administration requiring all new and updated vehicles in the sector to be new energy vehicles by 2025, and the provinces of Liaoning, Zhejiang, Anhui, Fujian and Guangdong jointly releasing a regulation offering subsidies for enterprises to buy or rent new energy vehicles.

Major parcel delivery companies have adopted new energy and clean energy vehicles in line with the State policy to promote low-carbon development, with JD Logistics, the logistics arm of e-commerce giant JD.com, adding more than 20,000 new energy vehicles in 50 cities across the country.

Reducing the high carbon emissions from parcel delivery vehicles is the key to making the industry greener, a report by the bureau's development and research center said in 2021.

Lin said the bureau will continue to step up the promotion of new energy and clean energy vehicles, adjust and optimize the features of the vehicles, promote the construction of supporting facilities, and guide delivery enterprises to use more new energy and clean energy vehicles through leasing and purchase.
