Ahead of Paris 2024, and building on the first Rings of Fire report in 2021, elite athletes from across 15 sports – including 11 Olympians – join forces with leading climate scientists and thermal physiologists to examine the serious threat extreme heat poses to competitors at the Paris Olympics.

Our new report, Olympic Smoke Rings has found that sponsorship deals between the 2024 Paris Olympic and Paralympics Games and just three polluting companies will generate 33.6 million tonnes of CO2 equivalent.

The organisers of EURO2024 have taken steps to mitigate carbon pollution but should be doing more to reduce its impact given the threat posed to football by extreme weather and the climate crisis.

The future of winter sports is closely interwoven with the future of the climate. Rising temperatures and the ensuing loss of snow cover are shortening seasons, creating difficult and sometimes dangerous skiing conditions. Many ski resorts are struggling and some have already had to close.

Major fossil fuel polluters like the car industry are promoting themselves through sport like the tobacco industry once did.

Rising awareness of the climate emergency means many in the world of sport - clubs, events, fans - are turning to offsetting as a well-intentioned way to compensate for the impact of their emissions. This briefing explores why that may be a mistake, why offsetting in its current form does not do what its name implies, and why, under certain circumstances, it can even be damaging.

Global climate change is already affecting all sectors of society. This report looks at how carbon pollution is visibly ruining winter sports, tells the story of how the collapsing snow sports sector is being used as a billboard by some of the very major polluters whose emissions are speeding its downfall.

How heat could impact the 2021 Olympics

The promotion of high carbon products and services through sponsorship is a serious issue for the future of our climate. High carbon companies cannot expect to keep deliberately marketing products which are driving potentially runaway, catastrophic climate destabilisation without facing any public scrutiny.

Playing against the clock: Global sport, the climate emergency and the case for rapid change – by leading academic and author, David Goldblatt, written for the Rapid Transition Alliance, provides the first provisional estimate of the impact of global sport on the climate and warns that the climate emergency will have far more severe consequences for several sports.
