CEMEX, S.A.B. de C.V. (NYSE: CX) announced today significant progress in many key performance indicators related to its global sustainable development strategy, highlighting important achievements in major areas such as workplace safety, environment and climate change, land management and biodiversity, and its contribution to the communities where it has its operations.

"During 2009, despite the challenges posed by the global economic crisis, CEMEX deepened its commitment to its sustainable development initiatives," said Lorenzo H. Zambrano, CEMEX Chairman and CEO. "Taken together, our initiatives to address climate change implemented since 2006 allow us to avoid more than 1.5 M tons of CO₂ emissions on an annualized basis, the equivalent of emissions made by about 290,000 passenger vehicles in one year. We reconfirm our commitment to address climate change and to the development of a low-carbon economy."
