Concrete EATS Greenhouse Gas Emissions?!?

Concrete production is thought to produce about 5% of climate changing greenhouse gas emissions. However, new science indicates that while producing concrete negatively impacts the environment, once produced, concrete actually absorbs carbon dioxide emissions. Last week on National Public Radio’s Science Friday show, researchers discussed how we could possibly use concrete in our efforts to clean up the environment. The benefits of concrete still do not outweigh the costs, but concrete still may prove to be a wiser choice than other materials, and we can find ways to use existing concrete instead of increasing production.
