Assessment of Decarbonization Pathways of Japan
… emissions over time remain flat at about 1,000 MtCO₂e, far exceeding the carbon neutrality goal. Even when Japan’s 2030 and 2040 NDC for CO₂ and power mix targets are fully achieved, residual emissions of 100 – 200 MtCO₂e remain, which calls for a need of carbon offsets. Relying on domestic-only …
