Zero Emission Tokyo

A page number:708-344-046



Our Goal: Zero Emission Tokyo

Tokyo has been implementing highly advanced climate change measures. Our urban cap-and-trade program, the world’s first to target office buildings and other large facilities, has been very successful. The covered facilities have achieved a significant 27 percent reduction from Base-Emission (the average CO2 emissions of three consecutive fiscal years selected by facilities between FY2002-FY2007). In addition to encouraging investment in energy-saving facilities such as LED lighting and renewable energy/energy sources, we have also been working to raise public awareness. Our efforts include establishing ‘Team Mottainai’ in partnership with many companies and NGOs.

At the same time, Tokyo is enhancing its appeal as one of the world’s leading economic centers with a concentration of diverse industries and advanced technologies. Tokyo’s economy is growing as a result, with an increase in our gross metropolitan product. Despite this, we are seeing a steady decline in our energy consumption. Addressing climate change not only reduces environmental risks, but also brings about benefits, opportunities and growth to society and the economy. It is also an important factor in achieving the SDGs (Sustainable Development Goals).

Additionally, the green finance market, including green bonds and ESG (Environmental, Social and Governance) investment, is growing tremendously throughout the world. Meanwhile, the impacts of climate change are becoming increasingly severe. Last year, in Tokyo we had an unusually hot summer. And in regions throughout Japan, we had downpours of unprecedented intensity that brought about significant damage, such as landslides.

According to the IPCC special report released last year, in order to keep global warming under 1.5 degrees Celsius—which has less risk than a 2 degree rise—we need to reduce CO2 emissions to net zero by around 2050. Today, as the huge impacts of climate change and the urgency for countermeasures come into sharper relief, the world is about to undergo a paradigm shift.

To protect the lives and property of the citizens of Tokyo, and to help decarbonize the world, the Tokyo Metropolitan Government has to take a new step forward. As a global megalopolis, Tokyo declares that it will seek to achieve the 1.5 degree goal, and by 2050, become a Zero Emission Tokyo that contributes to the world’s net-zero carbon emissions.

Commitments toward a Zero Emission Tokyo

Policy Direction for
Strengthening Commitments in Tokyo

  • We will implement a comprehensive range of measures both to alleviate and prevent global warming and to adapt to already observed impacts of global warming.
  • In addition to our existing efforts to promote energy efficiency and expand the use of renewable energy, we will also address food waste, reduction of plastics, and all other challenges deriving from urban activities, including supply chain activities.
  • We at the Tokyo Metropolitan Government (TMG) will take the initiative in environmental commitments through the united efforts across TMG to enhance its own sustainability. These efforts include the promotion of energy efficiency and the use of renewable energy for TMG’s facilities, activities under TMG’s Plastic Reduction Policy, and increased adoption of battery electric vehicles and other zero emission vehicles.
