15 celebrity images from Greenpeace's Save the Arctic campaign

Awareness around environmental causes have received a great boost from celebrities this week, with the Westwood campaign coinciding with Leonardo DiCaprio donating $15 million to animal, ocean and environment charities.

Andy Gotts was joined by Vivienne Westwood, Sadie Frost, and model Leebo Freeman when the images were unveiled on Monday (13 July).

Gotts describes Westwood as 'a remarkable woman' and says they came up with the idea for the T-shirt campaign after naturally clicking on set.

The two often meet, with Westwood creating a childrenswear line bearing the slogan 'I am not a terrorist', presenting her AW11 collection against the backdrop of a Nairobi slum and dedicating her SS14 collection to jailed whistleblower Chelsea Manning.

She is a vocal supporter of the Green Party and reportedly donated £300,000 to its 2015 general election campaign.
