Japan revises 2030 targets, plans to double renewables


The unprecedented Tokyo Olympic Games mean the world’s attention is focused on Japan, and The Land of the Rising Sun’s Ministry of Economy, Trade and Industry has taken the opportunity to revise its draft energy plan for 2030. The new plan sees an ambitious doubling of renewables and significant cuts to coal and gas. What is more, the draft plan also proposes the building of a hydrogen supply chain. 

The move comes in response to pressure from U.S. President Joe Biden, the upcoming Glasgow climate change conference in November, and the International Energy Agency’s (IEA) “Japan 2021 Energy Policy Review”, published earlier this year, in which IEA Executive Director Fatih Birol described the challenge ahead of Japan as “considerable”, and warned that even if Japan met its 2030 climate goals (pre-revision) “a very significant reduction of greenhouse gas emissions post-2030 will be necessary if Japan is to realise its ambition of achieving carbon-neutrality by 2050.” 

The new draft plan looks to cut Japan’s emissions by 46% (from 2013 levels) up from the original goal of 26%. To achieve that the world’s third largest economy needs renewables to account for 36-38% of its energy generation mix by 2030, a significant increase from the previous target of 22-24%. 

On top of that, the coal target has been revised down from 26% to 19%, and gas, upon which Japan relies heavily, is to be reduced from 56% to 41%. Amongst all this change, Japan’s nuclear target has remained unchanged at 20-22%. 

Interestingly, Japan has included new fuels like hydrogen and ammonia in its new draft plan, which it says will contribute 1% of the energy mix by 2030. However, the plan did not specify these new fuels had to be green.

Japanese Prime Minister Suga originally announced the revised 46% reduction in emissions at the April Leaders Summit on Climate, hosted by US President Biden. At the Summit, Suga said the reduction “would mean that Japan will raise our current target by over 70%, and it will certainly not be an easy task. However, by defining a top-level ambitious target befitting to a next growth strategy of the nation which underpins manufacturing in the world, Japan is ready to demonstrate its leadership for world-wide decarbonization.” 

What is not clear is just how Japan can increase its renewable generation so significantly over the course of the decade. The country is already so short on useable land that it is ripping up golf courses and replacing them with solar farms, utilizing floating PV on lakes and reservoirs, and looking to invest strongly in wind. However, much of the waters around Japan are too deep for traditional wind turbines, and floating wind turbines are still technologically nascent. 

Considering Japan is the largest buyer of Australian coal and thermal coal, and the world’s largest importer of LNG (buying $15 billion worth of Australia’s LNG exports in 2020), there is no doubt that Japan’s revised ambitions will have an impact on Australia, and perhaps particularly on the Morrison’s government’s controversial “gas-led recovery”, toward which it has already committed to funding private industry to the tune of $224 million for the development of onshore gas fields in the Northern Territory’s (NT) Beetaloo Basin.
