Definition Carbon Neutral or CO2 Neutral:


Carbon neutrality thus involves a 3-step process:

  1. calculating emissions;
  2. reducing emissions; and
  3. offsetting remaining emissions.

Carbon neutral means that – through a transparent process of calculating emissions, reducing those emissions and offsetting residual emissions – net carbon emissions equal zero.

Scientific Definition:  The adjective CO2-neutral (or climate-neutral) is used in various contexts. It states that the use of a fuel or even a human activity (e.g. a flight or an event) has no influence on the carbon dioxide concentration of the atmosphere and thus is not harmful to the climate. This is why we also speak of climate neutrality.

Occasionally, planned installations with CO2 capture and storage (CCS) are also referred to as CO2-neutral. However, this only allows CO2-reduced and not CO2-free energy, as not all CO2 can be separated and stored.

Note: The CCC Plant capture and store (CCS) 80- 90 % of the CO2 and reused in the plant. The last 10-20 percent that cannot be stored is compensated with additional biomass that have absorbed more CO2 than the plant cannot CCS.
