Beijing Low-Emission ZoneTo improve air quality and the health of residents, Beijing launched a low-emission zone in September 2017, banning heavy-duty freight vehicles with emissions below National IV Standards from entering the city. WRI China is working with the government on successful planning and implementation of this zone. Not only will the low-emission zone improve air quality, but it will also mitigate severe public health hazards and save an estimated 43 lives each year, leading to an annual social cost savings of $37 million.
