World: A Systems Change Lab report on the state of climate change action has warned that the global cement industry is making insufficient progress towards its 2030 climate change targets and that a step-change in action is required. It recorded the carbon intensity of global cement production at 635kgCO2/t in 2018 with the 2030 target of no more than 370kgCO2/t. The rate of change over the previous five years was reported as being 2.9% but an annual rate of change of 22.5% would now be required to meet the 2030 target.
It also noted that emissions intensity from the cement industry had actually increased slightly in recent years. It reached this conclusion by using a different methodology from the Getting the Numbers Right (GNR) project. Instead it estimated the global emissions intensity by using global data on process emissions and energy data from the International Energy Agency and the GNR.
The report said that the cement sector would need to go beyond traditional mitigation options such as improving energy efficiency and switching fuels to meet its climate commitments. However, carbon capture utilisation and/or storage (CCUS) and novel cements were described as costly and immature. In its view, “Decarbonisation in the long term thus will depend on significant investments in research, development, and demonstration, alongside efforts to create a demand for low-carbon cements and policies to support investment in decarbonisation technologies.” It described both strategies as, “not yet fully mature in terms of technology development, costs and scaling.” The ‘critical enablers’ it identified to help the cement sector meet its target included stricter regulations, increased demand for low-carbon cement and investment in pilot and industrial scale projects looking at novel cements.
Overall, the report said that change towards averting climate change across 40 key areas in power generation, buildings, industry, transport, land use, coastal zone management and agriculture was not happening fast enough and that none were on track to meet their respective 2030 targets. Change was happening but not at the required pace.
