Japan’s government has approved new targets to reduce greenhouse gas emissions, aiming for a 60% cut from 2013 levels by 2035 and a 73% reduction by 2040. The revised policy seeks to increase renewables to 50% of the electricity mix by 2040 while expanding nuclear power to 20%. Although 80% of 3,000 public comments supported a more ambitious target, the government finalised its targets without increases. Japanese utilities have struggled to restart nuclear reactors after the 2011 Fukushima disaster, prompting a shift towards next-generation reactors. The government also wishes to align decarbonisation with economic growth, promoting clean energy hubs. However, challenges include rising costs in the offshore wind market and global uncertainties, particularly due to shifts in US climate policies.
