A system of multipliers devised to enable warming effects of different gases to be compared.

Reductions of greenhouse gases achieved by a Clean Development Mechanism (CDM) project.

The term used by the Intergovernmental Panel on Climate Change (IPCC) to express the relationship between human-caused emissions that add to the Earth’s greenhouse effect — carbon dioxide along with other greenhouse gases — and the temperature changes that will result from these emissions.

Cars, large as they are, make for great repurposing — as a bed, sofa or one’s most talked-about showpiece, for example. Assuming one has the space, of course!

Refers to the tendency for urban areas to have warmer air temperatures than the surrounding rural landscape, due to the low albedo of streets, sidewalks, parking lots, and buildings.

Concerning substances that deplete the ozone layer, The Montreal Protocol is an international agreement entered into force in January 1989 to phase out the use of ozone-depleting substances such as methyl chloroform, carbon tetrachloride, and CFCs.

A catch phrase that covers various sustainable technology and methods, including the use of renewable energy, green chemistry and biofuels.

Also known as Earth Science, geoscience covers all forms of research concerned with the earth’s natural systems. This includes the study of the oceans, solid earth, biosphere and atmosphere.

An international forum that aims to develop, innovate and communicate the best practice approaches in environmental impact assessments.
