The  theme for World Environment Day on  5th June, 2012  is Green Economy.

The UN Environment Programme defines the Green Economy as one that results in improved human well-being and social equity, while significantly reducing environmental risks and ecological scarcities. In its simplest expression, a green economy can be thought of as one which is low carbon, resource efficient and socially inclusive.

Practically speaking, a Green Economy is one whose growth in income and employment is driven by public and private investments that reduce carbon emissions and pollution, enhance energy and resource efficiency, and prevent the loss of biodiversity and ecosystem services. These investments need to be catalyzed and supported by targeted public expenditure, policy reforms and regulation changes.

The Green Economy Initiative launched in 2008 has three main activities, which are to produce a Green Economy Report and related research materials, which will analyze the macroeconomic, sustainability, and poverty reduction implications of green investment in a range of sectors; to provide advisory services on ways to move towards a green economy in specific countries; and to engage a wide range of research, non-governmental organizations, business and UN partners in implementing the Green Economy Initiative.

Green Economy is therefore not just a passing environmental fad but is one of the best solutions available for sustainable economic growth that recognizes the social component.
