This study quantitatively analyzes the impact of greenhouse gas (GHG) emissions reduction policies on the global economy. To this end, we develop a multi-national and multi-industry static computational general equilibrium model that includes three components―GHG emissions from production, disutility due to GHG emissions, and governments' GHG emissions reduction policies. Then we calibrate the model with the relevant data and solve for the equlibrium using the most recent methodology (exact hat algebra). We find that the strengthening of unilateral GHG emissions reduction policies for each country reduces carbon emissions from domestic producers, but does not necessarily reduce global carbon emissions as production is relocated to other countries. On the other hand, we can reduce GHG emissions when all major countries simultaneously implement the strengthened reduction policies proposed by the OECD (2016). Our results imply that aligned reduction efforts of major countries are necessary to reduce global GHG emissions.
본 연구는 온실가스 감축정책이 세계경제에 미치는 영향을 정량적으로 분석하였다. 이를 위해서 생산에 따른 온실가스 배출, 온실가스 배출에 의한 비효용의 발생, 각국 정부의 온실가스 감축정책이라는 세 가지 요소를 포함하고 있는 다국가-다산업 정태적 연산가능일반균형모형을 개발하였다. 이렇게 개발된 모형의 파라미터 값을 추정하고 모형에 적용할 수 있는 가장 최근의 방법론(exact hat algebra)을 사용해서 모형의 해를 계산하였다. 모형의 예측에 따르면 국가별 개별적인(unilateral) 온실가스 감축정책의 강화는 해당 국가의 국내 생산과 탄소 배출을 감소시키지만, 생산이 다른 국가로 재배치되기 때문에 반드시 세계의 탄소 배출량을 감소시키지는 않는 것으로 나타났다. 반면 모든 주요국들이 동시에 OECD(2016)에서 제안된 강화된 감축정책을 추진할 경우에 전 세계의 온실가스 배출을 감소시킬 수 있는 것으로 나타났다. 우리 분석결과는 온실가스 감축정책이 효과를 발휘하기 위해서는 주요국들의 조율된(aligned) 감축 노력이 필요하다는 점을 시사한다.
