Global Cool is using Cake to handle its launch event at the British Museum next Tuesday (30 January).
The agency will work for the foundation over the next 12 months, promoting a series of events and handling its press office.
Global Cool was set up by former music promoter Dan Morrell, who co-founded Future Forests – now known as the CarbonNeutral Company – in 1997.
It is planning to use ‘cultural icons’ such as musicians and celebrities to lure people to the global movement behind carbon-emission reduction.
US pop band Scissor Sisters are among the charity’s supporters.
Cake head of PR Chris Wood leads the account.
‘The foundation wants a billion people to reduce their carbon emissions by one tonne,’ said Wood.
