The high-grade heat required for heavy industry—such as for the production of cement, steel, petrochemicals, and glass—accounts for nearly 10% of global CO₂ emissions. The pathways to decarbonizing this sector are unclear. Friedmann and colleagues have recently examined the state of low-carbon heating approaches for heavy industry. Existing options are costly, inadequate, or both. Increased efforts to decarbonize this sector through policy instruments and technology innovation are urgently needed.

持续加热重工业

重工业（例如生产水泥，钢铁，石化产品和玻璃）所需的高等级热量占全球CO ₂排放量的近10％。该部门脱碳的途径尚不清楚。Friedmann及其同事最近研究了重工业的低碳加热方法。现有的选择昂贵，不足或两者兼而有之。迫切需要通过政策手段和技术创新来加大对该部门的脱碳力度。
