CO₂ equivalents (abbreviation: CO₂-eq or CO₂e) are a unit of measurement for standardising the climate impact of greenhouse gases. In addition to CO₂, these also include the gases methane and nitrous oxide, as like CO₂ they are based on carbon.
The figures are based on the "Global Warming Potential" index defined by the United Nations IPPC (Intergovernmental Panel on Climate Change).

The negative climate impact of methane is 28 times higher than the impact of carbon dioxide, but methane does not remain in the atmosphere as long. Nitrous oxide has almost 300 times the climate impact of carbon dioxide. The conversion into equivalents makes the different greenhouse gases comparable.

Emissions are releases of greenhouse gases into the atmosphere over a certain area in a defined period of time.

The warming potential describes the climate impact of one unit of a greenhouse gas on the climate impact of one unit of CO₂ and is used to calculate CO₂ equivalents.

Primary energy is the energy that is contained in the particular energy sources - such as the calorific value of coal. When this is converted into usable energy (final energy) in power plants, conversion losses occur.

The United Nations (UN) defined 17 of these Sustainable Development Goals (SDGs) in 2016 to ensure global sustainable development at the economic, social and environmental levels by 2030. They are implementation goals and contain 169 targets, such as phasing out subsidies for fossil energies and for agricultural export subsidies.

Ecotoxicity refers to the harmful effects of toxic substances on living organisms in various ecosystems, such as water. Ecotoxicity is measured in paradichlorobenzene equivalents (1.4-DB-equ.). This is a unit that enables comparability of different harmful potentials, although the individual substances have different effect parameters, such as type of distribution, chemical reaction or persistence in the environment.
