This article discusses a recent Report that warns that the carbon footprint of heavy emitter cement companies must be reduced sharply in order to meet Paris climate goals.
Greenhouse gas emissions from cement production must be reduced sharply if the world is to meet the climate change goals set out in the Paris agreement, a new report has suggested.
Making cement and concrete, which is the most consumed product in the world after water, entails substantial emissions of carbon dioxide, from the chemical processes involved. While manufacturers have for years been seeking ways to reduce this or capture the carbon produced, and to make cement production more energy efficient, the results have failed to keep pace with the need to cut carbon emissions.
The Carbon Disclosure Project (CDP), which tracks greenhouse gas emissions from leading industries, found in a report published on Monday that Indian companies were performing best on reducing their carbon footprint, partly because they benefit from newer and more efficient manufacturing plants.
In Europe, emissions from cement production were supposed to be reduced under the EU’s emissions trading scheme, which has operated since 2005, under which heavy industries are awarded allowances for the carbon they produce, and if they need to emit more must buy spare permits from cleaner companies. But the price of permits repeatedly collapsed owing to over-allocation of allowances and the scheme does not operate to reduce emissions as much as intended.
