Offsetting GHG emissions by enterprises is one of the popular forms of reducing greenhouse gas emissions as part of the implementation of the company’s zero-emission strategy.
The following topics describe how the emission offset works.
The implementation of reduction projects leads to processes that contribute to the reduction of greenhouse gas emissions.
It is done as a result of activities that prevent or reduce the release of emissions into the atmosphere or remove GHG emissions from the atmosphere.
The GSS Cert System brings together investors of reduction projects that involve the reduction, avoidance and removal of GHG emissions.
CO2 is the most common anthropogenic greenhouse gas, but not the only one. There are many greenhouse gases, some of which have a thousands times more greenhouse effect than CO2.
Scientists in their studies assume that the greenhouse potential CO2 is the base potential of CO2 = 1. Based on this approach, the potentials of other gases, such as methane or nitrogen dioxide, are estimated. The conversion factor expressed in this way is marked with the letter “e” as an equivalent – CO2e.
All greenhouse gases have the ability to raise the temperature of our planet.
In order to be able to compare the effect of different greenhouse gases on Earth’s temperature, the Global Warming Potential (GWP) index was introduced. The GWP of a gas depends on how much heat it is able to absorb and how its concentration decreases over time.
An example of the differentiation of GWP of individual greenhouse gases is presented in the table. For example, the emission of 1 ton of CH4 (methane) corresponds to 28 tons of carbon dioxide (CO2) emissions. Tetrafluoromethane (CF4) has over 23,000 times the greenhouse effect of CO2.

Based on the level of reduced or avoided emissions related to the CO2 equivalent, reduction units are created, also known as carbon credits.
Carbon credit – is a tradable instrument certified by governments or independent certification bodies, representing the reduction, absorption or sequestration of emissions of one metric ton of CO2 or an equivalent quantity of other greenhouse gases CO2e.
The GSS Unit is the equivalent of a carbon credit.
The reduction units created under the certified and validated system may be traded between the entity producing these units (the investor of the reduction project) and the enterprise that wants to make an offset.
Platform of GSS Cert System is the place where one can sell and purchase GSS reduction units.
The buyer of the reduction unit can surrender it and thus count it as his own reduction of GHG emissions.
The GSS system enables surrendering/retiring of reduction units and confirms the reduction realized on behalf of the company (surrender certificate).
