Multi-gas Mitigation Analysis on Stabilization Scenarios Using Aim Global Model.

Non-CO₂ gas (CH₄, N₂O and F gas) emissions account for 25 percent of all greenhouse gas in the year of 2000. Main sources of CH₄ and N₂O emissions are agriculture-related activities such as enteric fermentation, paddy rice cultivation, soil management. A recursive dynamic CGE (Computer General Equilibrium) model has been developed to analyze greenhouse gas reduction options including non-CO₂ gas abatement technologies. Multi-regional, multi-sectoral and multi-gas CGE model and simple climate change model simulated long-term climate stabilization emission path. Preliminary results showed that multi gas mitigation options including CH₄ and N₂O abatement technologies will reduce GDP loss more than CO₂ only mitigation options for long-term climate stabilization, even though CO₂ mitigation options will reduce not only CO₂ emissions but non-CO₂ gas emissions simultaneously. It is necessary to collect regional non-CO₂ gas data (emission, technology options, and so on) and conduct more sensitivity analysis with computer simulation model to reduce uncertainty of non-CO₂ gas.
