The industrial sector is both a global economic powerhouse and a major emitter of greenhouse gas emissions: industry emits about 28 percent of global greenhouse gas emissions, of which 90 percent are CO2 emissions. In order to accelerate the global energy transition, industrial sectors must be decarbonised. Key areas of transforming industries are heavy industries such as steel, cement and chemicals, where renewables can be put to direct use. Another area is the interplay with the grid, where the industrial sector has huge potential for flexibility through demand-side management (DSM).
