UNEP's goodwill ambassadors - supermodel and activist Gisele Bundchen, Hollywood actor Don Cheadle and Chinese actor and activist Li Bingbing - all recorded video messages encouraging people to register their projects.

"Today we celebrate five inspiring projects, submitted for the World Environment Day 2012 challenge, that illuminate the pathway to a transition to a Green Economy," said UN Under-Secretary General and UNEP Executive Director Achim Steiner.

"The most environmentally friendly travel is by train, bus, carpooling, cycle or on foot, but in some countries making an eco-friendly project happen may need a private vehicle. If so, it should be fuel-efficient," he added. "This is why we are awarding such vehicles to these projects, most of which are run in developing nations with underdeveloped public transport networks."

The response to the challenge was strong, and after much deliberation UNEP is pleased to announce the following winners from a raft of inspiring activities:

About World Environment Day

WED aims to be the biggest and most widely celebrated global day for positive environmental action. WED activities take place year round but climax on June 5. WED celebrations began in 1972 and have grown to become the one of the main vehicles through which the UN stimulates worldwide awareness of the environment and encourages political attention and action.

Through WED, the UN Environment Programme is able to personalize environmental issues and enable everyone to realize not only their responsibility, but also their power to become agents for change in support of sustainable and equitable development.

In 2010, the dynamic WED challenge asked people to name baby gorillas in Rwanda to raise awareness, and in 2011 celebrities were asked to go head-to-head in a battle to have their supporters carry out the most activities, with the winner then planting a forest. Gisele Bundchen beat Don Cheadle, helping drive 4,229 WED activities in 144 countries - ranging from a bicycle rally in Nepal to a public litter clean-up in the Republic of Congo, and an environmental street procession by young people in Albania. Other celebrities such as Vampire Diaries star Ian Somerhalder and Bollywood regulars Priyanka Chopra and Rahul Bose have promoted the event over the last few years.
