In recognition of the power of millions of individual actions, Earth Day 2011 will be organized around A Billion Acts of Green: Personal, organizational and corporate pledges to live and act sustainably. 

At over 45 million actions to date, A Billion Acts of Green campaign – the largest environmental service campaign in the world – is steadily building commitments by individuals, corporations, and governments in honor of Earth Day.  A Billion Acts of Green inspires and rewards both simple individual acts and larger organizational initiatives that further the goal of measurably reducing carbon emissions and supporting sustainability.

The goal is to register one billion actions in advance of the Earth Summit in Rio in 2012. Get involved and make a difference! You can also follow on Facebook.
