Bureau Veritas introduced a Green Rating Composite Index which will provide charterers and regulators with a tool to compare the environmental performance of ships and will give owners a tool against which to assess environmental investment in the vessel. The Green Rating Composite Index builds on BV's international experience with rating the environmental performance of buildings and its research into new technologies to make ships more fuel efficient. "To encourage the market to use the most environmentally-friendly ships, and to encourage owners and yards to invest in greener technology, we must have a clear standard to compare the environmental performance of ships," explains Didier Chaléat, Senior Vice-President, Bureau Veritas.
