The One Earth Concert will take place on Saturday 28 January and feature a line up of 10 bands.
The Super Furry Animals, The Darkness and The Strokes have already been confirmed with more bands expected to be named in the next few weeks.
The event will be televised worldwide and is part of a global campaign by organisation Climate Change Now (CCN).
The concert will be broadcast in the UK by the BBC, and across the world to a global television audience of over a billion viewers.
All profits from the concert will go to the UK charity One Earth Trust.
Head of commercial development at the Millennium Stadium, Rupert Moon, said the aim of the event was to convert one million homes in Europe to renewable energy.
In addition he said the concert would also raise the profile of the stadium.
"We have raised in excess of £2m for charity. We have a commitment to charities in many ways, but also there are many big bands who want to play here because this is a must-play venue," he said.
He said the stadium would be also doing its bit towards the campaign, and aimed to convert to renewable energy by 2009.
Co-founder of CCN Michael Mathres said the concert would help raise awareness about the importance of the environment.
"People are genuinely concerned about the effects of climate change, but don't know how easy it is to make a big difference," he said.
"The concert will focus attention on the part we can all play in tackling climate change."
At the launch of the concert Mr Moon also unveiled the latest in a growing trend of stadium knitwear.
Following the popularity of Stadium chief executive Paul Sergeant's colourful woolly jumper during the build up to the Tsunami relief concert, Mr Moon said there was no option but to follow suit.
"He says it has been washed but it has the chief executive aroma about it," he said.
Tickets for the concert are £40, and go on sale from Tuesday.
