海藻吸収、温室ガス削減量に算定　来年度、国連報告へ―政府

　【ドバイ時事】政府は来年度から、海藻や海草に吸収された二酸化炭素（ＣＯ２）「ブルーカーボン」を、温室効果ガスの削減量として算定する方針を明らかにした。国連に提出する２０２２年度分の温室ガス排出・吸収量に関する報告書に、世界で初めて海藻・海草の吸収量を計上する。
　伊藤信太郎環境相が９日、アラブ首長国連邦（ＵＡＥ）のドバイで開催中の国連気候変動枠組み条約第２８回締約国会議（ＣＯＰ２８）の閣僚級会合で表明した。日本は温室ガスを３０年度に１３年度比で４６％削減し、５０年までに実質ゼロとする目標を掲げているが、森林に加え、海藻などによる吸収量も排出量から差し引く仕組みとする。（2023/12/09-22:10）

The Japanese government 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 revealed by Japanese Environment Minister Shintaro Ito at a ministerial meeting in Dubai on Saturday at the 28th Conference of the Parties to the U.N. Framework Convention on Climate Change, or COP28.
   Japan aims to cut greenhouse gas emissions by 46 pct in fiscal 2030 from the fiscal 2013 level and reduce them to virtually zero by 2050. To meet the goal, the country eyes a system to count carbon absorption by trees, seaweed and others as a reduction in emissions.
   Japan will include the amount of blue carbon in its report on greenhouse gas emissions and absorption for fiscal 2022 to the United Nations. This will be the first such step in the world.
   Japan and other major countries are obliged to submit such a report by April each year.
