The UNEP Billion Tree Campaign represents a unique worldwide tree planting initiative, aimed at empowering citizens to corporations and people up to presidents to embrace the climate change challenge. By 2008, 18 months since the launch of the initiative, the campaign has managed to catalyze the planting of two billion trees, double its original target. The campaign, spearheaded by the UN Environment Programme (UNEP) and the World Agroforestry Centre (ICRAF), was unveiled in 2006 as one response to the threat but also the opportunities of global warming, as well as to the wider sustainability challenges from water supplies to biodiversity loss.
