Japan has unveiled an ambitious goal to cut greenhouse gas (GHG) emissions by 60% from 2013 levels by 2035, surpassing its prior target of a 46% reduction by 2030. This updated plan, jointly developed by the environment and industry ministries, positions the nation toward achieving net zero by 2050.

“This target underscores the delicate balance between economic growth, energy security, and our commitment to decarbonization,” the ministries stated.

While this marks progress, the plan has drawn criticism for falling short of the 66% reduction recommended by the Intergovernmental Panel on Climate Change (IPCC) to limit global warming to 1.5°C. Japan, the world’s fifth-largest carbon emitter, remains heavily reliant on fossil fuels, which challenges its decarbonization goals.

Japan’s new target aligns with recent international efforts, including the U.S. commitment to a 61%-66% reduction below 2005 levels by 2035. However, environmentalists argue that Japan’s reliance on conventional energy sources undermines its climate ambitions. “This falls short of what is required to meet global climate goals,” stated a spokesperson for an environmental advocacy group.

Despite objections from climate experts and environmentalists during panel discussions, the government approved the target without revisions. The revised Nationally Determined Contribution (NDC) will be submitted to the United Nations in February after public consultations.

The move underscores Japan's strategy to balance economic stability, energy security, and environmental commitments. As global scrutiny intensifies, Japan’s challenge lies in transitioning to a sustainable future while managing internal and international pressures.
