In March 2016 on the International Day of Happiness, the Secretary-General of the United Nations, Ban Ki-moon, appointed Red from the Angry Birds as the Honorary Ambassador for Green.  The campaign, featuring the globally renowned mobile game character, encourages young people to take action on climate change and ensure a sustainable and happier future for all.

To commemorate Earth Day and to further promote this initiative, the United Nations Postal Administration (UNPA) will issue a new personalized stamp sheet featuring Red, on 22 April 2016.  This will also coincide with the signing of the historic Paris Climate Change Agreement by world leaders at UN Headquarters. The sheet in the denomination of $1.15 is composed of ten Angry Bird images. The tabs of the stamps feature the UN logo with text highlighting various ways to take climate change action, such as by recycling, taking public transportation and conserving water and energy.

The campaign, in partnership with Sony Pictures Entertainment, the UN Development Programme (UNDP) and UN Foundation, asks the general public across the world to make the Angry Birds happy by taking actions on climate change.
