To estimate traffic facility-oriented particulate matter (PM) emissions, emission factors are both necessary and critical for planners the community of professionals. This study used locally calibrated laser-scattering sensors to collect PM concentrations in a tunnel. Emission light-duty heavy-duty vehicles were found be higher autumn compared summer. Based on this study’s data analysis, terms ...

The impact of carbon emission trading (ETS) has been widely investigated. In contrast to the existing studies, this article explores for first time theoretical relationship between ETS and industrial green total factor productivity (IGTFP) tests it empirically. Furthermore, investigates mediating mechanisms possible regional heterogeneity influence on IGTFP. To end, a time-varying difference-in...
