Contribution to reduction of greenhouse gas emissions

Greenhouse gas concentrations are highest in the last 2 million years.

Greenhouse gas emissions continue to increase. As a result, the earth is now 1.1°C warmer than it was in the late 1800s. The World Meteorological Organization announced that for the eighth consecutive year since 2015, the global average temperature has been more than 1°C above pre-industrial levels. The possibility of exceeding 1.5°C, the effort target set in the Paris Agreement, is imminent.

Long-term observation of greenhouse gas emissions supports reduction efforts around the world.

Long-term global carbon dioxide (CO2) monitoring over a decade or more is essential to the realization of the Paris Agreement. GOSAT is the world's first satellite to become a "common measure", a means of accurately measuring greenhouse gases. As it is possible to accurately observe the distribution of carbon dioxide concentrations from space, GOSAT data provided by JAXA is used by each country to verify its own data meets the target values.

• 
  JAXA observes greenhouse gas emissions from human activities, the main cause of global warming, monitors the long-term increase in greenhouse gas concentrations over a period of more than 10 years as the world's first dedicated greenhouse gas observation satellite that supports the reduction efforts of countries, and provides data on concentrations in the lower atmosphere directly affected by greenhouse gas emissions, which are a factor in the increase in concentrations, thereby contributing to reduction policy.
  GOSAT-2 contributes to implementing effective reduction measures by intensive observation of large-scale emission sources such as cities, which account for the majority of CO2 and methane emissions, the main causes of global warming.
