The Southbank Centre has had a relationship with Shell stretching back to 2006 and lists the company as a partner on its website.
Chris Garrard, from the campaign group Culture Unstained, said the end of Shell’s involvement with the BFI and the Southbank Centre was a crucial milestone in the campaign.
A spokesperson for Shell said the decision not to renew the contracts had been taken last year and mutually agreed with the Southbank and the BFI.
The fossil fuel corporation has confirmed it is not renewing its corporate membership deals with the Southbank Centre and the British Film Institute (BFI) when they come up for renewal later this year.
