The Prince, an International Olympic Committee member who has competed in bobsleigh at the Winter Games, has been outspoken in the field of environmentalism in recent years, raising funds for ecological preservation through The Prince Albert II of Monaco Foundation.

In an article published on the Olympics website he has assessed a range of sustainability measures being taken at Paris 2024, which he claimed is "stepping up to this challenge more than any Games before - and they are doing so by focusing first and foremost on reducing emissions."

The timing of the article is somewhat unfortunate given yesterday's cancellation of the Open Water Swimming World Cup, a test event for Paris 2024, because of pollution in the Seine, which has prompted calls from World Aquatics for further urgent work to be done on cleansing the water.

But in terms of the larger picture, the Paris 2024 Organising Committee plans to halve carbon emissions compared to the average of London 2012 and Rio 2016. 

This target reflects both the IOC’s Olympic Agenda 2020+5 and the Paris Agreement on Climate Change, which world Governments signed in 2015.

"Going forward, this focus on carbon reduction will become a contractual requirement for all Olympic hosts," the Prince noted. 

"From 2030, the Olympic Host Contract sets binding requirements to minimise direct, as well as indirect, carbon emissions. 

"The same contract also obliges Games organisers to encourage stakeholders to take action against climate change.

"In line with the IOC’s philosophy of lower-impact Games that adapt to the needs of the host cities and their residents, Paris 2024 is minimising new construction. 

"Some 95 per cent of venues will be pre-existing facilities - refurbished and modernised, where necessary - or temporary structures. 

"The venues have been specifically chosen so they can be accessed by public transport.

"Paris 2024 is also setting new sustainability standards for major sporting events by encouraging energy conservation, innovation and creativity.

"These will be Olympic Games of a new era."

The articles described how the Olympic and Paralympic Games will be powered by 100 per cent renewable energy - mainly clean electricity, but also biogas.

All sites will be connected to the grid by network operator Enedis and supplied by EDF with renewable electricity sourced from wind and solar farms.

Avoiding the use of diesel generators has made it possible to reduce the equivalent of 13,000 tonnes of carbon emissions.

"These solutions will remain in place after the Games, allowing other events, in sport and beyond, to reduce their emissions too," Prince Albert said.

"Organisers have also reinvented the way sports events do catering, and pledge to serve 13 million meals and snacks in a more sustainable manner.

"The target is an average of 1kg of CO₂ per meal, compared with the 2.3kg French average.

"Some 80 per cent of ingredients will be French, and at least 30 per cent organic.

"The amount of plant-based products will be doubled, while that of single-use plastic will be cut in half.

"And while there are currently no solutions to fully eliminate the carbon footprint of large events, Paris 2024 is showing how this can be reduced, setting a clear pathway on how to bring the world together, in a much more sustainable way."
