• CEMEX to be an official COP16 sponsor

CEMEX, S.A.B. de C.V. (NYSE: CX), announced today its official participation in the 16th edition of Conference of the Parties of the United Nations Framework Convention on Climate Change (COP16). The conference, which will be held in Cancun, Mexico, aims to continue efforts toward creating an international consensus on cutting carbon emissions and finding solutions to climate change. In addition to being an official COP16 sponsor, CEMEX will play an important role in supporting the objectives of this year's meeting by presenting concise and effective proposals that demonstrate the significant role of ready mix concrete in a low carbon world.

"Climate change poses a very significant challenge to our society and CEMEX is committed to contributing to the development of a low carbon economy," said Luis Farías, CEMEX's Senior Vice-president of Energy and Sustainability. "We look forward to COP16 as an opportunity to leverage our expertise and partnerships to find innovative ways to address the factors that contribute to climate change. Putting concrete solutions forward at COP16 is one more step along the way."

CEMEX, together with its partners, will host a series of events to showcase many of its efforts to contribute solutions and proposals to climate change and biodiversity conservation challenges. CEMEX will participate in the following key opportunities:

CEMEX has also entered into an agreement with Mexico's Ministry of Environment and Natural Resources (Secretaria de Medio Ambiente y Recursos Naturales, SEMARNAT) to participate as an official COP16 sponsor. CEMEX's sponsorship will help offset carbon emissions at the 2010 United Nations Climate Change Conference (COP16) and to contribute resources to its SEMARNAT's Environmental Leadership for Competitiveness program.

The agreement outlines two commitments. The first is a sponsorship of US$100,000 to offset the carbon emissions generated by one of the official facilities that will host COP16 events in Cancun: the Climate Change Villa. The funds will be administered by Pronatura -a Mexican NGO dedicated to the conservation of flora, fauna and priority ecosystems - and used for reforestation and maintenance of 1,300 hectares in the state of Oaxaca, Mexico, which will benefit families in 10 communities in the state. This will help offset 10,000 tons of CO₂ emissions, the equivalent of approximately 25% of the total emissions estimated to be generated during COP16.

The second part of the agreement will provide US$150,000 to fund the Environmental Leadership for Competitiveness Program (El Programa de Liderazgo Ambiental para la Competitividad) in Mexico. Under the program, in which SEMARNAT provides matching funds, training and development programs are offered to small and medium-size companies to foster environmentally responsible practices such as improved water preservation, reduction in energy consumption and better waste management systems at their facilities. This joint effort will benefit approximately 540 companies with more than 4,300 training hours in environmental leadership.
