Several high visibility events including the Olympic Games in Italy, Sydney, Utah, and Greece; the World Summit on Sustainable Development in Johannesburg, and the 2004 Democratic and Republican National Conventions have implemented green practices with varied success.
A more recent example is that of Live Earth, a series of worldwide concerts held on July 7, 2007, that initiated a three-year campaign to combat climate change.
Such efforts aim to conserve resources, protect air and water quality, habitat and human health, and showcase sustainability practices and concerns.
Government agencies and non-profit organizations also promote these practices with research, recommendations, grants and technical support.
Green conventions, meetings, conferencing and events are part of an international movement to achieve a sustainable world economy and livable planet.
