Japan’s draft proposal to cut greenhouse gas emissions by 60% by 2035 from 2013 levels has ignited a debate over the adequacy of its climate commitments. This target, presented last month, represents a significant increase from the previous goal of 46% reduction by 2030. However, environmental experts and some political factions within Japan’s ruling coalition argue that this is still insufficient to meet global climate goals.
As Japan prepares to finalize its climate strategy, the pressure mounts for more substantial commitments that align with international climate goals. With significant investments in both carbon trading and renewable energy technologies underway, the effectiveness of these measures will be pivotal in determining Japan’s role in the global fight against climate change.
Experts have voiced concerns that Japan’s approach prioritizes economic growth and energy security over aggressive decarbonization. The government’s ongoing investment in “clean coal” technologies and fossil gas infrastructure has been criticized as counterproductive to achieving net-zero emissions by 2050.
The Climate Action Tracker continues to rate Japan’s overall climate targets as “insufficient,” indicating that without more ambitious policies, the country is likely to miss its critical emission reduction milestones
Key Developments In this Regard.
- Carbon Emissions Trading System: The Japanese government is set to introduce a carbon emissions trading system by April 2026, which will require 300 to 400 major companies emitting over 100,000 tons of CO2 annually to participate. This system aims to cover approximately 60% of Japan’s domestic greenhouse gas emissions, including key industries such as electricity and steel. Companies exceeding their emissions quotas will need to purchase additional allowances, potentially raising costs for consumers.
- International Pressure: The United Nations climate panel has emphasized the need for a 60% reduction in global emissions by 2035 compared to 2019 levels to limit global warming. Critics argue that Japan’s current trajectory does not align with these recommendations, with some suggesting that the country should aim for an 81% reduction to truly contribute to global efforts against climate change.
- Renewable Energy Initiatives: In addition to its emissions targets, Japan is also promoting the use of perovskite solar cells, aiming to generate 20 gigawatts of electricity by 2040. This initiative is part of a broader strategy to enhance renewable energy capacity and reduce reliance on fossil fuels.
