For Cement's Massive Carbon Footprint Some Concrete Steps

Cement is one of the global economy's most carbon-polluting industries Responsible for about 8 percent of global carbon dioxide (CO2) emissions in 2015 if it were ranked with individual countries the cement industry would be the third-largest greenhouse-gas emitter in the world behind only China and the United States And this already Get price

Cement is the Source of About 8% of the World's Carbon

Concrete is the most widely used man-made material in existence It is second only to water as the most-consumed resource on the planet But while cement -- the key ingredient in concrete -- has shaped much of our built environment it also has a massive carbon footprint From a report Cement is the source of about 8% of the world's carbon dioxide (CO2) emissions according to think tank Get price

Sequestration of CO2 by Concrete Carbonation

Mar 12 2010Carbonation of reinforced concrete is one of the causes of corrosion but it is also a way to sequester CO2 The characteristics of the concrete cover should ensure alkaline protection for the steel bars but should also be able to combine CO2 to a certain depth This work attempts to advance the knowledge of the carbon footprint of cement As it is one of the most commonly used materials Get price

Concrete change Making cement carbon

Pouring concrete can reduce CO2 emissions Many options can reduce cement manufacturing emissions and even make it a net climate benefit The right set of policies — including carbon pricing industry efficiency or emissions standards and government support of RD — can help ensure the necessary technologies are commercialized and adopted by industry Get price
