"The contribution of air quality policies to the carbon neutrality transition in Korea"
by Fouré, Jean, Elisa Lanzi and Daniel Ostale Valriberas

There is a large potential for synergies between climate policies and air pollution policies for several reasons. First, some air pollutant such as black carbon (BC) and methane (CH4) are also short-lived climate pollutant, therefore contributing to climate change. Second, the same mechanisms, such as the combustion of fossil fuels or the use of nitrogen fertilizers, can lead to the emission of both air pollutants and greenhouse gases. Finally, many sectors are large contributors to both environmental pressures, for instance, road transport (CO2 and also NOx and BC), iron & steel industry (CO2 and also PM2.5) or Agriculture (CH4, N2O and also NH3). Conversely, global warming can also increase the formation of secondary air pollutants in the atmosphere such as ground-level ozone.
This paper evaluates the potential synergies and tradeoffs between air quality policies and the net-zero emission transition in Korea - a country which has a carbon neutrality commitment by 2050 as well as ambitious air quality policies -, using the global multi-region multi-sector general equilibrium model ENV-Linkages. Preliminary results show that the carbon-neutrality transition has the potential to significantly reduce air pollutant emissions, whereas air quality policies only influence significantly methane emissions.
