THE World Wildlife Fund Cymru’s mascot Pippa the Panda joined pupils from Greenhill Primary, Gelligaer to launch a new search for local eco-warriors.

It wants to find unsung heroes of the environment, with Hidden Heroes aiming to highlight and recognise inspirational people who have gone the extra mile in helping to improve the environment in their local community.

This year’s initiative is being held in the run-up to Earth Hour – where hundreds of millions of people across the globe will be turning off their lights for one hour at 8.30pm on March 23.

The launch of Hidden Heroes was at Greenhill Primary as it has been dubbed ‘the greenest school in the UK” because it generates electricity from four wind turbines and an array of solar panels, with surplus energy exported to the grid.

It is also highly energy efficient, with the top A+ rating and the school also harvests rainwater.

Greenhill has also signed up to WWF Cymru’s green ambassador scheme, which aims to encourage a new generation of sustainability champions.

Winners of the Hidden Heroes competition will receive a £500 cash prize to support a green initiative of their choice and will be invited to receive their award and celebrate Earth Hour at an exclusive ceremony in central London on March 23.

To enter complete a simple on-line entry form at, providing details of a nominated Hidden Hero and telling WWF about the positive difference they’ve made.

Nominations close on March 4.
