Japan to Calculate “Blue Carbon” For Emissions Cut

The Japanese government said it plans to calculate the amount of “Blue Carbon” or carbon dioxide absorbed by seaweed and sea grass, as a reduction in greenhouse gas emissions.

The plan was announced by Japanese Environment Minister Shintaro Ito at a ministerial meeting in Dubai at the 28th Conference of the Parties to the U.N. Framework Convention on Climate Change, or COP28.

The Japanese government aims to cut greenhouse gas emissions by 46% by 2030 from the fiscal 2013 level and reduce them to virtually zero by 2050.

To meet the goal, the country is formulating a system to count carbon absorption by trees, seaweed, and other natural assets as a reduction in emissions.

Minister Ito said Japan will include the amount of blue carbon in its report on greenhouse gas emissions and absorption for fiscal 2022 to the United Nations, the move will be the first such blue carbon submission.

The Japanese minister also unveiled an aid package for developing countries, including providing satellite data on emissions and helping them introduce an early warning system for weather disasters.
