To raise awareness of its Save the Arctic campaign, Greenpeace enlisted the talents of designer and activist Vivienne Westwood to create a T-shirt illustrating its cause.
As part of the project, photographer Andy Gotts captured 60 celebrities from the worlds of television, film, music and fashion showing their support for the cause by wearing the T-shirt.
The images will be on display in advertising slots at Waterloo tube station in London until July 26 and it is hoped that the gallery of images will help raise further public awareness for 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.
The campaign aims to prevent oil drilling in the Arctic and is backed by a petition with more than 7 million signatures.
It is thought that such drilling could limit the habitats of native wildlife or result in damaging oil spills which would pollute the surrounding waters and create yet another threat to the world's oceans.
Andy Gotts was joined by Vivienne Westwood, Sadie Frost, and model Leebo Freeman when the images were unveiled on Monday (13 July).
Westwood and Gotts met when the photographer shot the fashion designer for a project named iCons, which he was creating for Elton John.
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.
Westwood drew on her extensive fashion contacts for the shoot, which features top British models Kate Moss, Naomi Campbell, Lily Cole and Alice Dellal, while stars including Coldplay singer Chris Martin, George Clooney, Tracey Emin and Nicole Scherzinger were keen to show their support.
Having campaigned on issues from fracking to nuclear disarmament and climate change, Westwood has become as famous for her activist work as her fashion designs in recent years.
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.
Most recently the designer shaved off her hair to draw attention to the impacts of climate change and appeared in a PETA video in support of World Water Day.
She is a vocal supporter of the Green Party and reportedly donated £300,000 to its 2015 general election campaign.
Members of the public who are persuaded to join the Save the Arctic campaign will have the opportunity to purchase the T-shirt - which comes in baby, child and adult sizes - from Westwood's website with all profits going to straight to Greenpeace.
