This WRI analysis finds that renewable energy supplies are set to double collectively in eight major economies by 2030 spurred on by new national climate and energy plans. These renewable energy levels will be 18 percent higher in 2030 than previously projected growth rates.
WRI works with partners to track and analyze national climate policies in Japan. Learn more about our Open Climate Network project.
In one of the least aggressive climate action plans of any developed country to date, Japan announced its commitment to reduce its emissions 26 percent below 2013 levels by 2030.
This chart uses historical GHG emissions data and the targets and timetables in submitted pre-2020 pledges (for 2020 reductions) and INDCs to estimate the average annual change in emissions (decarbonization rate) from 2020-2030.
This chart presents each target against each chosen base year to help facilitate easy comparisons.
Some reports say Japan will set a target to reduce its greenhouse gases 20 percent below 2013 levels by 2030. Research shows that the country can go much further, achieving reductions of 31-37 percent by 2030.
Coverage of Japan’s coal funding has sparked an important debate about the role of international climate finance in facilitating the transition to a low-carbon economy.
Recently the world took two giant steps toward reaching a global agreement to fight climate change in 2015: a landmark U.S.-China accord and a $4.5 billion pledge to the Green Climate Fund by the United States and Japan.
But there are some conditions attached.
After the 2011 Fukushima Daiichi nuclear disaster, Japan halted all existing nuclear operations and significantly scaled back its 2020 emissions-reduction target. As Japan revises its energy policy over the next few years, officials will decide the future of the country’s energy mix—and its climate action.
New research reveals that Japan can likely go beyond its emissions-reduction target with existing initiatives, but needs to pursue more ambitious action in the long-term to truly overcome the climate change challenge.
An Overview of the Current Policy Landscape
In 2013, in the aftermath of the Fukushima Daiichi nuclear power plant disaster, the government of Japan put forth a revised target to reduce greenhouse gas (GHG) emissions by 3.8 percent from 2005 levels by 2020.
This paper analyzes this target and finds that Japan can likely meet it by...
WASHINGTON—The Intergovernmental Panel on Climate Change (IPCC) released the Working Group II (WGII) portion of its Fifth Assessment Report on climate change. The report focuses on the current and future impacts of climate change and outlines the benefits of reducing emissions and options regarding climate adaptation.
