Paving the Way to Zero Emissions From Cement

Cement is the world鈥檚 most important building material. When mixed with water, cement glues together the sand and gravel in concrete, used for buildings, roads, tunnels, bridges, dams, pipes and other kinds of infrastructure. The world produces an astonishing four billion metric tons of cement a year 鈥� half a ton for everyone on Earth. Because it is the most critical material for creating infrastructure, demand for cement is growing faster than population growth.

Concrete Solutions That Lower Both Emissions and Air Pollution

Sometimes, fixing one problem can create another.

Concrete production contributes 8 percent of global greenhouse gases, and demand continues to rise as populations and incomes grow. Yet some commonly discussed strategies to reduce the sector鈥檚 global GHG emissions could, under some scenarios, increase local air pollution and related health damages, according to a study from the 不良研究所.

Making Cement Sustainable

Cement production accounts for up to nine percent of global anthropogenic carbon dioxide emissions, according to the World Business Council for Sustainable Development. Sabbie Miller, assistant professor in the Department of Civil and Environmental Engineering, aims to change that by finding alternative ways to make cement or replace it altogether.

People have been using cement as a building material for thousands of years. Mixed with water and rock fragments, it forms concrete for buildings, highways and bridges.
