Matthew Dieumegard-Thornton will attempt to reach the summit of Mount Everest to help raise awareness of global environmental and sustainability issues and to commemorate The Queen's Diamond Jubilee.
The 21 year old from Sleaford wants to raise money for the charity Global Angels to provide water for disadvantaged children and their communities for the next 20 years. As an ambassador of Climate Unchange he also wants to highlight the continuing fight against "environmental irresponsibility".
He will start his attempt on the 8848 metre summit in mid-April and the challenge is scheduled to take 70 days. It will follow the south-eastern route taken by Sir Edmund Hillary in 1953 when he became the first man to reach the top of Mount Everest, three days before Queen Elizabeth's coronation.
