LAPs, such as carbon monoxide, hydrocarbon, sulfur oxide, nitrogen oxide, ozone, and particulate matter, as well as GHG emissions from the transport sector are rapidly increasing in the PRC. Various measures to control LAPs have been implemented in the country, along with the adoption of strategies to mitigate GHG emissions. The connection between LAP and GHG emission control and reduction offers an opportunity to address both problems simultaneously. This paper highlights the methodology’s potential to help maximize measures and strategies that have significant co-control effects.
