Massive Attack has commissioned Tyndall Centre for Climate Change Research, to create a plan for concerts and tours to have zero emissions, or as close to zero as possible.
"The research will be looking at how to reduce the amount of energy used during concerts and in moving musicians, crews and sets between different venues and cities, as well as the impact audiences have.... Live concerts and performances generate 405,000 tonnes of greenhouse gas emissions every year. Thirty four percent of which comes from the venue and 33% from audience travel. Band travel, accommodation, merchandise, and promotions also contribute to emissions".
