中國海油集團6月1日宣布，我國海上首個百萬噸級二氧化碳封存工程在南海東部海域正式投用，累計封存量將超150萬噸，相當于植樹近1400萬棵。
China's first offshore million-tonne carbon storage project was put into operation on Thursday in the South China Sea, according to the China National Offshore Oil Corporation (CNOOC). The project is designed to store a total of more than 1.5 million tonnes of carbon dioxide (CO2), which is equivalent to planting nearly 14 million trees, according to the company.

【知識點】
“海上碳封存”，全稱為“海上二氧化碳地質封存”，二氧化碳封存是減少大氣中二氧化碳濃度的有效方法之一。首先是要找到合適的存儲位置。位置選好后，就要通過鉆井建立一條往“碗”里輸二氧化碳的通道。最后海洋石油專家們創新性地為注氣管柱加裝了光纖監測裝置，每隔一米就有一個監測點，就像數千只敏銳的眼睛，在看不見摸不著的幾千米井下無死角觀察注氣管柱是否存在泄漏。二氧化碳注入地層后，大部分將被頂部的蓋層永久蓋住，同時一部分被地層孔隙捕獲，一部分慢慢溶解在地層水中，還有一部分與巖石和地層水反應生成碳酸鹽礦物。
中國海域地殼穩定性好、沉積盆地分布廣、地層厚度大、構造地層圈閉多，具備封存二氧化碳的良好地質條件，封存潛力達2.58萬億噸。6月1日，我國首個百萬噸級海上碳封存示范工程——恩平15-1油田碳封存示范工程在珠江口海域正式投用。這標志著我國初步形成了海上二氧化碳注入、封存和監測的全套鉆完井技術和裝備體系，填補了我國海上二氧化碳封存技術的空白。
【重要講話】
推動經濟社會發展綠色化、低碳化是實現高質量發展的關鍵環節。加快推動產業結構、能源結構、交通運輸結構等調整優化。實施全面節約戰略，推進各類資源節約集約利用，加快構建廢棄物循環利用體系。完善支持綠色發展的財稅、金融、投資、價格政策和標準體系，發展綠色低碳產業，健全資源環境要素市場化配置體系，加快節能降碳先進技術研發和推廣應用，倡導綠色消費，推動形成綠色低碳的生產方式和生活方式。
A green and low-carbon economy and society are crucial to high-quality development. We must work faster to adjust and improve the industrial structure, the energy mix, and the composition of the transportation sector. We will implement a comprehensive conservation strategy, conserve resources of all types and use them efficiently, and move faster to put in place a system for recycling waste and used materials. Fiscal, taxation, financial, investment, and pricing policies and systems of standards will be improved to support green development. We will boost green and low-carbon industries and improve the system for market-based allocation of resources and environmental factors. We will accelerate the R&D, promotion, and application of advanced energy-saving and carbon emission reduction technologies, encourage green consumption, and promote green and low-carbon ways of production and life.
——2022年10月16日，習近平在中國共產黨第二十次全國代表大會上的報告
實現碳達峰碳中和是中國高質量發展的內在要求，也是中國對國際社會的莊嚴承諾。中國將踐信守諾、堅定推進，已發布《2030年前碳達峰行動方案》，還將陸續發布能源、工業、建筑等領域具體實施方案。中國已建成全球規模最大的碳市場和清潔發電體系，可再生能源裝機容量超10億千瓦，1億千瓦大型風電光伏基地已有序開工建設。
Achieving carbon peak and carbon neutrality are the intrinsic requirements of China's own high-quality development and a solemn pledge to the international community. China will honor its word and keep working toward its goal. We have unveiled an Action Plan for Carbon Dioxide Peaking Before 2030, to be followed by implementation plans for specific sectors such as energy, industry and construction. China now has the world's biggest carbon market and biggest clean power generation system: the installed capacity of renewable energy has exceeded one billion kilowatts, and the construction of wind and photovoltaic power stations with a total installed capacity of 100 million kilowatts is well under way.
