Linkin Park's Music for Relief organization has done a lot of good for a lot of people. The band's co-vocalists, Chester Bennington and Mike Shinoda, attended the Climate 2014 Summit Monday and Tuesday (Sept. 22 and 23) to renew their continued support for sustainable energy.

The event gave the band a chance to speak with a number of U.N. world leaders and politicians about some of the climate issues that affect the world today. Linkin Park have been avid supporters of the Sustainable Energy for All initiative, launching their association with the 'Power the World' campaign back in 2011.

During their visit, both Bennington and Shinoda spoke about climate change during the globally webcast Social Good Summit. The rockers also posed for photos with the UN's Kandeh Yumkella and Al Gore as can be seen in the posts below.
