GSS reduction units
What is the GSS unit

The GSS unit is a certified and ISO 14064-2 compliant confirmation of the implemented additional and voluntary action, which results in the reduction, avoidance or increase in the removal of GHG, corresponding to 1 ton of CO2e emission equivalent.

The number of units is calculated in accordance with the so-called methodologies that precisely describe how to quantify the emission reduction activities for a specific type of project and which emission sources are within the boundaries of the calculation.

GSS System may use validated methodologies developed for CDM UNFCCC projects or new methodologies developed under the System.

The eligibility of the project and the calculation of the number of offset units in accordance with the methodology and on the basis of collected source data are confirmed by the validation and verification process by external, independent certifying organizations.

GSS units are created in the Scheme registry only after the verification of the correctness of the calculations by the verifier for the emission reduction that has actually been achieved (ex-post).


The reduction unit is transferable, meaning that you can buy it from the project owner to claim that they have limited the negative impact of human activities on the climate to a specific magnitude.


GSS units are certified carbon offset units, compliant with the requirements of ISO 14064-2, which can be used to offset emissions which are difficult-to-avoid on your carbon footprint in order to achieve climate neutrality status.

By surrendering a sufficient number of GSS units, you can offset your own negative impact on climate change thus becoming climate neutral.

Types of GSS units

There are 3 types of offset units within the GSS Cert System – each one corresponding to the emission equivalent of 1 ton of CO2. Depending on the project and activity they relate to, units are additionally marked with a 3-letter tag:

  • GSS-red – a unit that represents the reduction or avoidance of greenhouse gas emissions
  • GSS-seq – a unit representing the absorption / removal of greenhouse gas emissions from the atmosphere in a biological process using natural processes
  • GSS-tec – a unit representing the absorption / removal of greenhouse gas emissions from the atmosphere in a mechanical / chemical process using technological solutions
Features of GSS units

Each GSS unit (confirmation of emission reduction or enhancement of greenhouse gas removals):

  • is unique and identifiable by an individual serial number,
  • is based on a realistic and credible baseline scenario,
  • is calculated, monitored, reported and independently verified,
  • has a clearly defined and transparent system of controlling its origin and managing the process of its creation,
  • represents the permanent reduction or absorption of GHG,
  • is used only once to fulfill the GHG reduction commitment, the so-called emission offset by the buyer.
GSS stands for quality

In the process of System development, we used the knowledge and experience of experts with twenty years of international practice in the field of emission trading systems and the implementation of reduction projects. We have analyzed all present systems generating offset units, international guidelines, standards and criteria for GHG reduction programs.

This, combined with our proprietary IT solution based on blockchain technology and “artificial intelligence”, allowed us to create a Monitoring, Reporting and Verification System (MRV) and a System’s Registry that guarantee security, transparency and the highest level of quality of generated units:

  • compliance with the requirements of ISO 14064-2,
  • verification in accordance with the requirements of ISO 14064-3,
  • only ex-post units and without the risk of loss of durability (no permanence risk),
  • the ability to fully trace each GSS unit from its generation to its retirement, with complete information on all raw data, emission factors used, calculation algorithms and the verification process,
  • minimizing the points of manual data transfer, thanks to the automation of the collection and processing process,
  • logging each operation related to the GSS unit generation and transfer process,
  • central calculation algorithms, validated by an external, independent certification body, without the possibility of introducing changes after the validation is completed,
  • online access to full project documentation for verifiers and access to full data analytics,
  • horizontal and vertical data analysis provided by the System along with the mechanism of detecting data irregularities based on “artificial intelligence”,
  • the ability to instantly confirm the status of a GSS unit online via the website and a QR code.
UN Sustainability Criteria

The 2030 Agenda for Sustainable Development, adopted by all Member States of the United Nations in 2015, is a joint agenda for peace and well-being for people and the planet, for now and for the future. At its core there are 17 Sustainable Development Goals (SDGs), which are an urgent call for action by all countries – developed and developing – within a global partnership. They recognize that ending poverty and other deprivations must go hand in hand with strategies that improve health and education, reduce inequalities and stimulate economic growth – all while tackling climate change and working to protect our oceans and forests.

Each GSS unit (reduced, avoided or removed emissions) is linked to activities contributing to the achievement of at least 3 Sustainable Development Goals. We require project participants to carry out additional activities for the benefit of the environment or local communities, and allocate part of the funds obtained from the sale of units to these additional projects.
