“Your Green Idea” launches officially on 15 March following a soft launch of the website.
The creative strategy behind the initiative and the “Your Green Idea” web portal has been developed by creative communications agency Aqueduct.
M&S will promote the initiative through an advertising campaign that aims to encourage customers to submit their environmentally friendly ideas.
A judging panel will choose the top three ideas, which the public can then vote on. The winning idea will be adopted nationwide by M&S and the person behind it will win £100,000 to fund a separate green project for the organisation of their choice.
