Energy industry CO2 emissions Japan 2013-2022

In 2022, the carbon dioxide emissions of the energy industry in Japan amounted to more than 420.16 thousand kilotons of CO2. The carbon dioxide emissions peaked in 2013 at 526.3 thousand kilotons, but more recent figures indicated a downward trend. To reduce its carbon footprint, Japan aims to increase the shares of nuclear and renewable energy it uses. 

The energy industry as the main CO2 polluter

In recent years, the largest sector to create CO2 emissions in Japan was the energy conversion sector, followed by the industry and the transportation sector. The main reason is that fossil fuels remain the largest sources in energy production.
Tokyo represents the largest region to consume electricity. The capital is one of the world's most populated cities and the largest industrial region in Japan.

Japan's efforts to restructure its energy sector

Due to its own scarce natural resources, Japan is heavily dependent on fossil fuel imports to produce its energy. In order to reduce its energy insecurity and to reduce greenhouse gas emissions, Japan is currently working on restructuring its energy sector. The government aims to replace fossil fuels with renewables and nuclear energy to become entirely carbon-neutral by 2050. These measures are already showing an effect, as the primary energy self-sufficiency rate increased in recent years.
