The Montreal Protocol on Substances that Deplete the Ozone Layer, also known simply as the Montreal Protocol, is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion. Open for signature on 16 September 1987, it was made pursuant to the 1985 Vienna Convention for the Protection of the Ozone Layer, which established the framework for international cooperation in addressing ozone depletion. The Montreal Protocol entered into force on 1 January 1989, and has since undergone nine revisions, in 1990 (London), 1991 (Nairobi), 1992 (Copenhagen), 1993 (Bangkok), 1995 (Vienna), 1997 (Montreal), 1998 (Australia), 1999 (Beijing) and 2016 (Kigali).
The United Nations Environment Programme (UNEP) is responsible for coordinating responses to environmental issues within the United Nations system. It was established by Maurice Strong, its first director, after the United Nations Conference on the Human Environment in Stockholm in June 1972. Its mandate is to provide leadership, deliver science and develop solutions on a wide range of issues, including climate change, the management of marine and terrestrial ecosystems, and green economic development. The organization also develops international environmental agreements; publishes and promotes environmental science and helps national governments achieve environmental targets.
A green economy is an economy that aims at reducing environmental risks and ecological scarcities, and that aims for sustainable development without degrading the environment. It is closely related with ecological economics, but has a more politically applied focus. The 2011 UNEP Green Economy Report argues "that to be green, an economy must not only be efficient, but also fair. Fairness implies recognizing global and country level equity dimensions, particularly in assuring a Just Transition to an economy that is low-carbon, resource efficient, and socially inclusive."
Green building refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. This requires close cooperation of the contractor, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. In doing so, the three dimensions of sustainability, i.e., planet, people and profit across the entire supply chain need to be considered.
Environmental education (EE) refers to organized efforts to teach how natural environments function, and particularly, how human beings can manage behavior and ecosystems to live sustainably. It is a multi-disciplinary field integrating disciplines such as biology, chemistry, physics, ecology, earth science, atmospheric science, mathematics, and geography. The United Nations Educational, Scientific and Cultural Organisation (UNESCO) states that EE is vital in imparting an inherent respect for nature among society and in enhancing public environmental awareness. UNESCO emphasises the role of EE in safeguarding future global developments of societal quality of life (QOL), through the protection of the environment, eradication of poverty, minimization of inequalities and insurance of sustainable development. The term often implies education within the school system, from primary to post-secondary. However, it sometimes includes all efforts to educate the public and other audiences, including print materials, websites, media campaigns, etc.. There are also ways that environmental education is taught outside the traditional classroom. Aquariums, zoos, parks, and nature centers all have ways of teaching the public about the environment.
Global Environment Outlook (GEO) is a series of reports on the environment issued periodically by the United Nations Environment Programme (UNEP). The GEO project was initiated in response to the environmental reporting requirements of UN Agenda 21 and to a UNEP Governing Council decision of May 1995 which requested the production of a new comprehensive global state of the environment report.
The Global Scenario Group (GSG) was an international, interdisciplinary body convened in 1995 by the Tellus Institute and the Stockholm Environment Institute (SEI) to develop scenarios for world development in the twenty-first century. Further development of the Great Transition scenarios has been carried on by the Great Transition Initiative (GTI).
Proposals for the creation of a United Nations Environmental Organization (UNEO) have come as some question the efficacy of the current United Nations Environment Programme (UNEP) at dealing with the scope of global environmental issues. Created to act as an anchor institution in the system of Global Environmental Governance (GEG), it has failed to meet those demands. The UNEP has been hindered by its title as a Programme as opposed to a specialized agency like the WTO or WHO, in addition to a lack of voluntary funding, and a location removed from the centers of political power, in Nairobi, Kenya. These factors have led to widespread calls for UNEP reform, and following the publication of Fourth Assessment Report of the IPCC in February 2007, a "Paris Call for Action" read out by French President Chirac and supported by 46 countries, called for the UNEP to be replaced by a new and more powerful United Nations Environment Organization, to be modelled on the World Health Organization. The 52 countries included the European Union nations, but notably did not include the United States and BRIC, the top five emitters of greenhouse gases.
Green growth is a term to describe a path of economic growth that is environmentally sustainable. It is based on the understanding that as long as economic growth remains a predominant goal, a decoupling of economic growth from resource use and adverse environmental impacts is required. As such, green growth is closely related to the concepts of green economy and low-carbon or sustainable development. A main driver for green growth is the transition towards sustainable energy systems. Advocates of green growth policies argue that well-implemented green policies can create opportunities for employment in sectors such as renewable energy, green agriculture, or sustainable forestry.
Environmental governance is a concept in political ecology and environmental policy that advocates sustainability as the supreme consideration for managing all human activities—political, social and economic. Governance includes government, business and civil society, and emphasizes whole system management. To capture this diverse range of elements, environmental governance often employs alternative systems of governance, for example watershed-based management.
Sustainable event management is the process used to produce an event with particular concern for environmental, economic and social issues. Sustainability in event management incorporates socially and environmentally responsible decision making into the planning, organisation and implementation of, and participation in, an event. It involves including sustainable development principles and practices in all levels of event organisation, and aims to ensure that an event is hosted responsibly. It represents the total package of interventions at an event, and needs to be done in an integrated manner. Event greening should start at the inception of the project, and should involve all the key role players, such as clients, organisers, venues, sub-contractors and suppliers.
The International Resource Panel is a scientific panel of experts that aims to help nations use natural resources sustainably without compromising economic growth and human needs. It provides independent scientific assessments and expert advice on a variety of areas, including:
The United Nations Environment Programme Finance Initiative is a global partnership established between the United Nations Environment Program (UNEP) and the financial sector. It was created in 1992, following the Earth Summit in Rio de Janeiro. The UNEP FI consists of 215 members from financial institutions and 41 supporting institutions. These members include banks, investors and insurance companies.
This is a list of notable events relating to the environment in 1999. They relate to environmental law, conservation, environmentalism and environmental issues.
In economic and environmental fields, decoupling refers to an economy that would be able to grow without corresponding increases in environmental pressure. In many economies, increasing production (GDP) currently raises pressure on the environment. An economy that would be able to sustain economic growth while reducing the amount of resources such as water or fossil fuels used and delink environmental deterioration at the same time would be said to be decoupled. Environmental pressure is often measured using emissions of pollutants, and decoupling is often measured by the emission intensity of economic output. No empirical evidence supports the possibility of absolute decoupling economic growth from environmental impacts.
The Millennium Ecosystem Assessment (MA) is a major assessment of the human impact on the environment, called for by the United Nations Secretary-General Kofi Annan in 2000, launched in 2001 and published in 2005 with more than $14 million of grants. It popularized the term ecosystem services, the benefits gained by humans from ecosystems.
