20 CEMENT AMERICAS • Spring 2019 • www.cementamericas.com FEATURE T he Sierra Club California claims that California's cement plants have higher emissions per ton of cement than similar facilities in China, India and other major cement-pro- ducing regions. The Coalition for Sustainable Cement Manufacturing & Environment (CSCME) states that the Sierra Club report "paints an inaccurate and intentionally misleading picture of the California cement industry." So went the opening volley of a new war against the cement industry. "There are a lot of things the cement industry can do to reduce its energy and process emissions, but few, if any, of California's cement factories have undertaken any of these measures," said Ali Hasanbeigi, the principal author of the Sierra Club report and CEO at Global Efficiency Intelligence, an international energy and climate technology consulting firm. "This study benchmarked California's cement facto- ries against their peers, and the results are not flattering." In "California Cement Industry: Failing the Climate Chal- lenge," Hasanbeigi and co-author Cecilia Springer recom- mend various options to help the state's cement industry reduce energy use and GHG emissions. These include: investments in more energy efficiency processes; fuel switching; clinker substitution; use of alternative materials (e.g. engineered wood and high-performance polymers); and carbon capture, utilization and storage (CCUS). CSCME provided the following rebuttal: • The California cement industry has significantly reduced its carbon footprint, while greenhouse gas (GHG) emis- sions from other cement industries, such as China's, have grown exponentially (20 percent decrease in California The California Cement Battle The Sierra Club Released a Report Attacking California Cement Plants, But The Cement Industry Hit Back.
