Roadmap to Beyond Net Zero

摘要

The UK concrete and cement industry has launched a roadmap to become net negative by 2050, removing more carbon dioxide (CO_2) from the atmosphere than it emits each year. Launching the ambitious plan, UK Concrete, part of the Mineral Products Association (MPA), has identified that net zero can be met through decarbonized electricity and transport networks, fuel switching, greater use of low-carbon cements and concretes, as well as carbon capture, usage or storage (CCUS) technology for cement manufacture. The 'Roadmap to Beyond Net Zero' calculates the potential of each technology and the carbon savings which can be achieved. CCUS technology is vital to delivering net zero manufacturing and, according to the roadmap, will deliver 61% of the required carbon savings. A net negative industry by 2050 will be achieved by using the natural, in-use properties of concrete, which include its ability to absorb CO_2 during use, and the benefit of using the thermal properties of concrete in buildings and structures to reduce operational emissions.
