Challenge 2011

The Climate Week Challenge 2011 was Britain’s largest ever environmental competition, with a staggering 145,000 people taking part across six age categories.

Thousands of school children and office workers across the country all received the same challenge: to come up with a green idea to save or make money.

The one-day version, which took place on Monday 21 March, was a live competition where 72,000 people were registered to take part in teams of four to six, brainstorming and presenting their concepts in a time-pressured situation.

Entries included some truly inspiring ideas, like the Fidgit (winner, ages 11-14), a toy that converts the energy of fidgeting children into electricity, and the Flood Prevention Pipe (winner, ages 5-7), which would encircle the globe, taking water from flooded areas to areas of drought.

A judging panel of celebrities, including footballer Gary Neville, singer Eliza Doolittle, and adventurer Ben Fogle, then chose the winners.

The one-hour version of the Climate Week Challenge could be run at any time throughout the week, and 73,000 people were registered to take part. A full list of judges, winners, and finalists can be seen by clicking here for One Day Challenge winners and here for One Hour Challenge Winners.
