CO₂ emissions coefficients for each coal power technology and fuel type

Conventional coal power has the highest CO₂ emissions, followed by LNG, based on CO₂ emission coefficients, technology, and fuel type. The Japanese government is promoting ammonia, but with 20% ammonia co-firing, reductions are minimal due to emissions from ammonia production, and even 100% ammonia firing emits over 1.5 times more CO₂ than LNG power.
