The Indonesian cement company Indocement — majority owned by the Heidelberg Cement Group of Germany — along with the World Bank and the group of six governments and the 17 companies that make up the Prototype Carbon Fund (PCF), signed an agreement in June for PCF's first cement sector project for reducing greenhouse gas emissions.

The Sustainable Cement Production project is sponsored by Indonesia's second-largest cement producer PT Indocement Tunggal Prakasa Tbk. The project plans to reduce greenhouse gas emissions by implementing technologies and techniques not yet applied in the country's cement industry. Indocement intends to introduce new types of cement to the country, as well as undertake fuel change projects in the company's three Indonesian locations.

The project is meant to adhere to the Clean Development Mechanism of the Kyoto Protocol, which allows industrialized countries and companies with greenhouse gas reduction commitment to purchase some of their required reductions in developing countries. The Sustainable Cement Production project opens possibilities for this and other nations, in which reductions in greenhouse gases are exchanged for development dollars.
