排出量取引、年１０万トン以上に参加義務　企業３００～４００社が対象―政府

　政府は２０日、２０２６年度に本格導入する二酸化炭素（ＣＯ２）の排出量取引制度について、年間１０万トン以上のＣＯ２を排出する企業に参加を義務付ける方針を明らかにした。対象は鉄鋼や電力など排出量の多い業界の３００～４００社を想定。国内の温室効果ガス排出量の約６割をカバーできる見通しだ。
　２２日に開く政府の有識者会議で制度の方向性を示す。この制度は、政府が対象企業にＣＯ２排出枠を毎年度無償で割り当て、枠を超えて出した企業には市場で枠の購入などを求める仕組み。排出量が少なければ枠の売却や将来への繰り越しも可能にする。超過分の枠を購入しない企業にはその分に応じた負担金を科す。（2024/11/20-17:57）

The Japanese government plans to require companies that emit more than 100,000 tons of carbon dioxide a year to participate in the country's carbon emissions trading system to be introduced at full scale in fiscal 2026, it was learned Wednesday.
   The requirement is expected to apply to around 300 to 400 companies in high-emitting industries such as steel and electricity.
   As a result, the system is seen covering about 60 pct of domestic greenhouse gas emissions.
   The government is slated to unveil its plans for the carbon emissions trading system at a meeting of experts on Friday.
   Under the system, the government will allocate CO2 emission quotas to companies free of charge every fiscal year, and requires those with emissions exceeding their limits to buy quotas through market trading. Companies with low emissions can sell their remaining quotas or carry them over to the next fiscal year.
