The Environment Ministry says Japan's greenhouse gas emissions fell to a record low in the fiscal year that ended in March.
The ministry's preliminary figures show Japan emitted one-billion 244-million tons of carbon dioxide in fiscal 2018, down 47 million tons, or 3.6 percent, from the previous year. It was the fifth straight yearly decline.
Japanese Prime Minister Shinzo Abe has instructed Cabinet ministers to draw up long-term strategies to cut greenhouse gas emissions by the time the G20 summit convenes in Osaka in June.
The 2016 Paris Agreement on climate change aims to reduce global greenhouse gas emissions to virtually zero in the second half of this century. Signatory nations are required to submit their strategies by 2020.
Japan has launched a new satellite to observe greenhouse gases. Ibuki-2, also known as GOSAT-2, will survey carbon dioxide and other global warming gases with greater precision than its predecessor.
An H2A rocket carrying the satellite lifted off from the Tanegashima Space Center in Kagoshima Prefecture, southwestern Japan, at 1:08 PM on Monday.
