But before we show you a video of Vivienne Westwood choosing the winning design -- let's meet the judges.
"I feel honoured to represent Girl Guides and Girl Scouts around the world as a judge for Flag for the Future. Recently I took part in another competition at school to design couture fashion made from recycled materials and now I find myself travelling to meet one of the world's top designers who also really cares about the planet!
"I am one of the millions of people who have signed the 'Save The Arctic' scroll because I fear for the animals that might become extinct and the exploitation that would occur in the Arctic if we don't take action. I can't bear to think about an Arctic without polar bears and icebergs with their beautiful colours and patterns. The Arctic is very far away from my home in Ireland but it is still my responsibility and the responsibility of everyone in the world to make sure that it becomes a global sanctuary."
Aishah is a 15 year old Girl Guide who lives in Cork, Ireland with her brothers and mother.
"We need to move towards an energy revolution where sustainable forms of clean energy can fuel our future. I am honoured to be a judge for the Flag of the Future competition because the youth of today are the future and their creativity is what we need in order to make positive change a reality."

Dame Vivienne Westwood was born Vivienne Isabelle Swire in Glossop, Derbyshire, UK on 8th April 1941. She began designing in 1971 along with her then partner Malcolm McLaren when London was at the forefront of cultural trends.
By the end of the seventies Vivienne Westwood was already considered a symbol of the British avant-garde and punk movements. Vivienne Westwood is now recognized as a global brand and Westwood herself as one of the most influential fashion designers in the world today. Vivienne Westwood today continues to show all over the world including in Paris, Milan and London.
She uses the medium of her shows to talk about culture and politics, more specifically about the urgent need to act against climate change.
"Judging the flag for the future has made me think a lot about the use of symbolism in different cultures. For example the colour blue is a symbol of peace and also known to keep bad spirits away. The flag must be global and I wanted to keep in mind that not every country has the same meaning of doves or rainbows.
"I was looking for a flag that made me feel peace, hope and unity. I also wanted a design that made me feel empowered and stirred up inside because we are working together to care for our planet and for the Arctic and together I hope that we will achieve peace."

Raquel has worked at the Inuvik Youth Centre where she encourages young artists to pursue training. As well as being a celebrated sculptural artist she also speaks at conferences on the issue of Indigenous rights.
"Having experienced its breath taking beauty first hand, I am extremely concerned for the future of the Arctic. As the sea ice retreats and the oil industry moves north, it is crucial that the youth of today continues the ongoing effort to protect this pristine wilderness and oppose those who seeks to exploit it. Therefore I am thrilled to be part of the 'Flag for the Future' project and look forward to reviewing the entries."

The last word
We would like to thank the judges and everyone who participated, and leave the last word to Sarah (13) from Malaysia, who submitted the winning flag design:
“As a member of Girl Guides Association of Malaysia, I feel very happy and honoured to be part of the effort to Save the Arctic and the historic flag ceremony. We need to protect the Arctic because it is the home of many indigenous peoples and many animal species. It should be declared a global sanctuary.
"I found out about the competition during my Environmental Journey in India visit last December at Sangam, World Centre of the World Association of Girl Guides and Girl Scouts. After looking at a photo of the two brave Girl Guides taken in the Arctic, I decided to do my little part by participating and supporting the campaign to Save the Arctic.
"This is a golden opportunity for me to send the message of hope and peace to the rest of the world. We can only save the Arctic for future generations if we are united in peace and harmony."
