Ⅰ. Introduction
1. Background and necessity of research
o Spread of carbon neutrality discussion and policy establishment
ㅇ According to the ‘Special Report of Global Warming of 1.5℃’ published by the IPCC in 2018, to limit the increase in global average temperature to within 1.5℃, global net emissions of greenhouse gases must reach net zero by 2050.
ㅇ Consensus on the importance and urgency of responding to the climate crisis is spreading around the world, with many countries declaring carbon neutrality and seeking a rapid transition to a decarbonized economy.
ㅇ Korea is also joining the international community’s efforts to achieve carbon neutrality, including the preparation of the ‘2030 Nationally Determined Contribution (NDC) Target Enhancement Plan’.
o The need to evaluate the effect of simultaneous reduction of greenhouse gases and air pollutants
ㅇ To achieve carbon neutrality, structural changes in social, economic, and technological systems are required, and such omnidirectional changes will inevitably bring additional impacts in addition to the targeted greenhouse gas reduction.
ㅇ Greenhouse gases and air pollutants have similarities in their emission sources and emission activities, so it is highly likely that air pollution will be reduced simultaneously while promoting carbon neutrality policy. However, there is uncertainty, as quantitative analysis on this matter has not been performed.
ㅇ Air quality policies are expected to have limited ripple effects compared to carbon neutrality policies because the policy means and scope are often localized and specific. W
