How to Decarbonize Concrete for a Better Future

Concrete, the most utilized human-made resource on Earth, is at the forefront of urban development and infrastructure expansion, with projections suggesting its production will rise from 14 billion to 20 billion cubic meters by 2050 due to increasing urbanization. However, the manufacture of concrete, particularly cement, its primary ingredient, is a major environmental concern as it accounts for 7% of global carbon dioxide emissions. This stark environmental impact underscores the urgent need for innovative solutions to decarbonize cement production to mitigate climate change.

The article highlights several global initiatives aimed at fostering such innovation. Notably, the World Economic Forum's First Movers Coalition seeks to leverage the purchasing power of companies to promote zero-carbon technologies in sectors that are challenging to abate. Similarly, international efforts like the Global Cement and Concrete Association, Mission Possible Partnership’s Concrete Action for Climate, and the Clean Energy Ministerial’s Industrial Deep Decarbonisation Initiative are mobilizing policymakers and industries to commit to concrete action towards reducing emissions.

Examples of national commitments include France’s policy to cut emissions from cement production by 35% by 2030, Japan's roadmap for the same, and the U.S. Inflation Reduction Act, which incentivizes carbon capture, utilization, and storage (CCUS) technologies with substantial tax credits. These collaborative efforts are crucial for meeting global climate goals and ensuring sustainable development amidst growing infrastructure demands.
