Japan has announced a new target to reduce greenhouse gas emissions by 60% by 2035, compared to 2013 levels. This ambitious goal aims to put the country, a significant global carbon emitter, on a path to achieving net-zero emissions by 2050. However, the plan has drawn criticism for potentially lacking the necessary ambition to effectively address climate change.

The strategy, announced by a joint panel of the trade and environment ministries, is currently undergoing a public comment period before final approval by the Japanese cabinet. This updated commitment aligns with similar moves by other nations, including the UK and the US, in advance of the February deadline for submitting revised climate targets under the Paris Agreement. Japan’s previous pledge was a 46% reduction by 2030, also from 2013 levels.
Balancing Decarbonization with Economic Growth
Environment Minister Keiichiro Asao emphasized the importance of reaching net zero by 2050, acknowledging the diverse opinions on the emissions reduction target. He stressed the need to balance decarbonization efforts with sustained economic growth, considering the long-term impact on future generations and society.
Japan faces significant challenges in transitioning to a lower-emission energy system. Over 60% of the nation’s electricity generation in the previous year relied on coal and natural gas. Restarting nuclear power plants has encountered regulatory hurdles, while limited land availability restricts the expansion of solar and onshore wind power.
Concerns Over Target Adequacy and Investment Needs
The proposed 60% target has sparked criticism from scientists and climate activists who argue it falls short of international goals to limit global warming to 1.5C above pre-industrial levels. A business lobby, concerned about access to clean energy, advocated for a reduction of at least 75%, while the National Governors’ Association also urged a higher target. Even within the ruling political coalition, there have been calls for a more ambitious reduction goal.
BloombergNEF estimates that achieving net zero emissions in Japan would require a substantial $7.7 trillion investment in the energy sector by 2050, encompassing low-carbon assets and infrastructure. Climate Action Tracker’s analysis suggests that an 80% reduction by 2035 would be necessary to align with the 1.5C global warming limit.
Critique of the Consultation Process
The new target emerged from government consultations with external experts, including academics and business leaders. However, Shota Ikeda, president of renewable energy firm Hachidori Solar and a member of the consultation panel, criticized the process, stating that discussions primarily focused on economic costs rather than the potential damage from exceeding the 1.5C warming threshold. Ikeda advocates for a minimum 66% reduction by 2035, in line with guidelines from the Intergovernmental Panel on Climate Change (IPCC).
Conclusion: Ambition and Implementation Challenges
Japan’s new 60% emissions reduction target by 2035 signifies a step towards decarbonization but faces significant challenges in terms of ambition and implementation. Balancing economic concerns with the urgency of addressing climate change, coupled with overcoming obstacles in transitioning to cleaner energy sources, will be crucial for Japan to meet its long-term net-zero goals and contribute effectively to global climate action. The public comment period and subsequent cabinet decision will be pivotal in shaping the final trajectory of Japan’s climate policy.
