Paris 2024 has announced French based multinational energy organisation Suez as its latest official partner, meaning the bid has now secured more than €26 million (£23.5 million/$29 million) in private sector funding.
Suez, which is based in Paris, "provides innovative solutions to protect water resources and to treat and recover waste", it is claimed.
With a focus on sustainable and green initiatives, Suez has 82,000 employees operating in 70 countries across five continents.
In addition to providing financial support to the bid, Suez will use its expertise in sustainable management to "support Paris 2024’s vision for reinvention and renewal in the city" and to help promote sustainable practices across the city and country".
"Aligned to Agenda 2020, sustainability is at the heart of Paris 2024 and we are delighted to partner with Suez," said Paris 2024 co-chairman Tony Estanguet.
"It is a multinational organisation that will bring invaluable expertise in sustainable practices.
"Suez’s approach to sustainable development mirrors that of the bid and we are looking forward to working together to drive the project forward."
Suez joins a host of other international brands in signing a partnership with Paris 2024, including French bank BNP Paribas and advertising systems company JCDecaux amongst others.
"Suez employees are proud to support the Paris bid to host the 2024 Olympic and Paralympic Games," said Suez chief executive Jean-Louis Chaussade.
"Suez wishes to lend its expertise, skills and experience to help Paris 2024 get the most out of its city centre resources and employ a collaborative approach that creates a sustainable blueprint in major event bidding."
Two other candidates will battle Paris for the right to host the Olympics and Paralympics in eight years’ time - Budapest and Los Angeles.
Rome have "interrupted" their bid following opposition from the Italian capital's Mayor Virginia Raggi.
The International Olympic Committee is due to elect the host city for 2024 at its Session in Lima on September 13 next year.
