Starting with the 70’s, the international literature mentioned various eco-green terms as: Ecological Policy, Environmental Policies, Environmental Diplomacy, Ecological Diplomacy, Eco-Diplomacy, Ecological Economy, Green Economy, the New economy of nature, all these expressions being used to maximize the importance of the environmental protection, the use of the unpolluting energies, preservation of the Earth, life protection, natural resources valuation and their preservation, promotion the policies on environmental policies through ecological education and through ecological diplomacy.
Green Economy. ‚Green Policies’ (20600 internet quotations) and ‘Green Economy’ (over 3,8 millions internet quotations) are some of the most preferred terms for public use. UNEP-United Nations Environment Program (environment for development) has developed a working definition of the Green Economy as an economy that may have results in improved human well-being and social equity, while significantly reducing environmental risks and ecological scarcities. The Green Economy is actually the economy which is:
- low carbon,
- resource efficient and
- socially inclusive.
The Green Economy is one whose growth in income and employment it 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 attitudes need to be catalyzed and supported by targeted public expenditure, Green Policies reforms and many regulation changes.
The UNEP Green Economy Iniţiative, launched in late 2008, consists of various themes whose collective overall objective is to provide the analysis and policy support for investing in green sectors and in greening environmental unfriendly sectors. Within UNEP, the Green Economy Iniţiative includes three sets of activities:
- Producing 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 from renewable energy to sustainable agriculture and providing guidance on policies that can catalyze increased investment in these sectors
- Providing advisory services on ways to move towards a Green Economy in specific countries
- Engaging a wide range of research, non-governmental organizations, business and UN partners in implementing the Green Economy Iniţiative.
Beyond UNEP, the Green Economy Iniţiative is one of the nine UN-wide Joint Crisis Iniţiatives (JCI) launched by the UN System’s Chief Executives Board in early 2009. In this context, the Iniţiative includes a wide range of research activities and capacity building events from more than 20 UN agencies including the Bretton Woods Institutions, as well as an Issue Management Group (IMG) on Green Economy, launched in Washington, DC, in March 2010.
