Cement emits as much CO2 as India. Why is it so hard to fix?

[also it emits mercury!]

"...Not only does the carbon dioxide from the reaction spill into the atmosphere, but cement producers also use huge amounts of coal or natural gas to heat the kiln."

As a result, the cement industry generates 8 percent of global carbon emissions — triple the emissions of the aviation industry.
