S&P adds green index

Standard & Poor's launches U.S. Carbon Efficient Index, riding the wave of investor interest in green investment themes.

Investors received another tool Monday designed to track green themes and greenbacks.

Standard & Poor's launched on Monday its S&P U.S. Carbon Efficient Index, designed to measure the performance of large-cap U.S. companies operating with a low carbon emissions footprint.

The index, which currently has 362 companies gleaned from the S&P 500, are selected using calculations from Trucost, an environmental data gathering organization.

David Blitzer, chairman of Standard & Poor's Index Services index committee, said in a statement, "Organizations around the world are paying greater attention to the impact of greenhouse gases on our climate, as increasingly more investors consider carbon efficiency as an important investment theme."

The U.S. Carbon Efficient Index is part of S&P's global thematic index series, which also covers such green themes as water, forestry, and carbon efficiency.

Microsoft, Cisco, Apple, and Google are among the tech companies included in the U.S. Carbon Efficient Index.
