By 2023, Japan's CO2 emissions per unit of manufacturing value added were anticipated to see a declining trend. Forecasts from 2024 to 2028 indicate a steady decrease, reflecting improvements in energy efficiency and shifts towards decarbonizing the manufacturing sector. The CO2 emissions metric was 0.18 kg per USD in 2023 and is predicted to decrease to 0.16 kg per USD by 2028.

Future trends to watch for include:

Enhanced adoption of green technologies and practices in manufacturing.
Policy developments aimed at further reducing industrial emissions.
Greater international pressures and partnerships influencing Japan's manufacturing decarbonization efforts.
