Do California Cement Factories Pollute More Than Those In China Or India? Study Suggests Time To Further Reduce Carbon Emissions.

California’s cement industry could be overhauled if Sierra Club California and a Bay Area Assembly member get their way.

A new Sierra Club study says cement production is responsible for 5 percent of carbon pollution globally.

“This is one industry that has managed to keep the status quo even though the science is showing we need to do everything we can to curb greenhouse gases,” said Kathryn Phillips, director of Sierra Club California.

Researchers also found that California’s cement factories are more polluting than their counterparts in China and India. “I was expecting California, being a green kind of state, to perform better,” said the report’s author Ali Hasanbeigi. “To our surprise we found it is one of the worst performing when it comes to carbon emissions.”
