In a recent development, Japan’s environment and industry ministries have established a new goal to decrease greenhouse gas emissions by 60% from 2013 levels by 2035. This initiative, spearheaded in the run-up to World Earth Day, builds on a previous plan aimed at a 46% reduction by 2030 and sets the stage for further deep cuts by 2040, as part of Japan’s broader commitment to achieving net zero emissions by 2050.
The revised target was introduced in response to the U.S. proposing a similar, aggressive climate agenda—even if there should be changes in federal policy under a new presidential administration. Despite this, the target has been met with criticism from environmental groups and some political figures who argue that, for one of the world’s largest carbon emitters, the goal is not ambitious enough, especially given Japan’s continuing reliance on fossil fuels.
While climate activists reiterate that the reduction falls short of the guidelines suggested by the Intergovernmental Panel on Climate Change for limiting global warming to 1.5 degrees Celsius, expert panels overseeing the plan maintained the proposed levels. Their decision reflects a balance between economic growth, energy security, and the urgent need for decarbonization.
Looking ahead, Japan plans to present this updated Nationally Determined Contribution to the United Nations in February, following a period of public consultation. The submission is part of a broader strategy that aligns with Japan’s renewed basic energy plan and an integrated national vision for decarbonization and industrial transformation.
