What is Low-Carbon Concrete?

The active ingredient in concrete is cement, and concrete’s ubiquitous usage makes cement the most widely used industrial commodity today. The world consumes about half a ton of cement per person per year. But alongside its positive benefits as a construction material, cement also puts a major strain on the environment. Cement production currently accounts for 3% of world energy consumption and roughly 8% of global greenhouse gas emissions. Reducing emissions from the cement sector is critical to meeting the United Nation’s goal of limiting global warming to 1.5°C, but the sector has proven inherently challenging to decarbonize. This challenge is prompting a major drive to develop technological solutions that can address these processing emissions, including significant upticks in both investments and startup activity in low-carbon cement.
