A partnership between Volvo Car UK and the Eden Project has been extended until 2027.
This means a fleet of nine fully electric XC40s will continue to be used to transport Eden Project staff and visitors around and beyond its site in Cornwall.
In addition, Volvo is exhibiting an EX30 as part of an off-street parking exhibit, and providing support to an early years programme.
Volvo Car UK managing director Nicole Melillo Shaw said: “Volvo aims to be a pioneer in protecting people and the planet, and we have set bold targets as a company to be completely climate neutral by 2040.
“We know we need to do more, and that we need to find like-minded organisations and people to work with to be part of the solution.
“We are delighted to extend our partnership with the Eden Project, an acknowledgment of our shared vision and ambition for a safer, sustainable future.”
Eden Project CEO Andy Jasper said: “The Eden Project is incredibly proud of our continuing relationship with Volvo Car UK. Volvo are not only completely in tune with the Eden Project mission, but they are also leaders in sustainable transport and a huge brand that is recognised and trusted around the world.”
