The pair wants the worldwide campaign to be the largest in history.  The concerts will take place in seven continents with locations such as Brazil, South Africa, New York, Paris, Australia and China. It will feature 100 performers with the likes of Metallica, The Police and Madonna, BBC reported.

Al Gore said that the vision for the event is "a billion voices with one message, to demand climate action now."  This is to encourage more world leaders to agree on reforms to manage climate change starting at the UN Climate Talks in Paris this December.

Television producer Kevin Wall is also working with Al Gore on the project to show the concerts to two billion viewers via 193 television channels.  Williams will be the Live Earth's creative director and his goal is to "harmonize" people across the globe instead of focusing on the featured artists.

The singer also joined the successful Live Earth campaign in 2007. However, the said affair gained criticisms for the artists who campaigned about "cutting carbon emissions" but flew around the globe at the same time.

William admitted that the comments were true and said that there were artists who do not grasp global warming. The "Happy" singer assured viewers that the team will have a different take this year.

With that statement, Wall added that music is limitless and exceptional in conveying messages. There is no need for language and Williams is going to use that tool to reach out to the world about climate change.

This is not the first time that the musician supported campaigns for climate change. In 2007, the artist collaborated with Madonna for the song "Hey You." Twenty five cents from each downloaded song for the first one million was donated to Alliance for Climate Protection.

Live Earth 2015 will start its concert series on June 18.
