Avoided Deforestation

Tropical deforestation is one of the largest sources of greenhouse gas emissions. International studies into the economics of climate change mitigation show that avoided deforestation is one of the most effective ways of reducing these emissions. Deforestation can be defined as permanent conversion of forest to an alternative land use.

Biomass

Living or recently-dead organic material that can be used as an energy source, excluding organic material that has been transformed by geological processes, such as coal or petroleum.

Embodied Carbon

The total carbon emissions, quantified in equivalent tonnes of carbon or carbon dioxide, associated with the manufacture and production of specified materials or construction of a building.

Energy Efficiency

Using less energy to fulfil the same function or purpose; this term is usually attributed to a technological solution rather than to a change in behaviour.

Fossil Fuel

Fuel such as coal, petroleum and natural gas, formed by the decomposing remains of plants and animals under immense heat and pressure over millions of years. These fuels, which together have generated most of the energy consumed globally for over a century, contain a high percentage of carbon and hydrocarbons.

Operational Carbon

The total carbon emissions, quantified in tonnes of carbon or carbon dioxide, associated with the running of a process or plant, for example, heating and lighting systems in a building.
