World cities improving energy efficiency: report

AFP - Some of the world's largest cities are improving their energy efficiency, a report said Thursday, while nations struggle to forge a global response to climate change.

Cities are taking action to reduce their carbon emissions and better manage their water strategy, said a report by the Carbon Disclosure Project (CDP), which runs a platform for companies and cities to measure, disclose, manage and share environmental information.

The 110-city report from the London-based organisation follows the G8 summit of world leaders hosted by Britain this week.

Los Angeles led the way, managing annual energy savings of $13 million (9.85 million euros) -- largely by retro-fitting traffic signals and street lights --followed by Washington and Las Vegas with $6.3 million, the CDP found.
