Miss Earth 2012, Alabang, Muntinlupa City, Philippines

The Miss Earth pageant has grown over the years, with an increasing number of countries participating each year. The number of national Miss Earth pageants has grown on every continent as well.
The Miss Earth pageant started to cohost in 2006 the United Nations Environment Programme's Champions of the Earth, an annual international environment awards established in 2005 by the United Nations to recognize outstanding environmental achievers and leaders at a policy level.
In 2006, the host country Chile failed to meet the requirements of the host committee; the pageant was moved back to the Philippines.
Since it began the pageant has been held annually in the Philippines, either October or November, and televised nationwide via ABS-CBN and Studio 23 with international delayed telecasts in more than 80 countries via STAR TV and The Filipino Channel.
