Support and Implementation

Contact us to get support and discuss implementation of Atmo in your country, city or organisation.

We will be happy to provide you with additional information on the possible setups and timing of implementation projects, service levels and costing of various standard and customized services related to the data management arrangements for GHG Inventory and MRV systems.

Atmo is more than a GHG Inventory and MRV system, it is a generic platform for data collection and reporting to any reporting regime. If you need a robust data management solution for your international, national, local or corporate5 reporting, we will be delighted to provide a customization of Atmo for that.


  1. Spherical is an independent software company. We are not affiliated with UNFCCC or UNFCCC secretariat in any way.
  2. The final ETF rules are not yet known. If and where the rules to be adopted by UNFCCC Parties will make it mathematically impossible to transition to the Enhanced Transparency Framework without additional efforts, these efforts will not be spared. Spherical is closely following the negotiations and will make efforts to minimize impact of any incompatible changes for its clients.
  3. At the moment of writing, the compatibility of IPCC Software's data structures and the existing UNFCCC reporting standard for Annex I Parties is very limited. The import is possible for all inventory variables that have a counterpart with the same business meaning in the UNFCCC reporting standard. The scope of possible import may increase or decrease as negotiations of the ETF progress. Spherical is closely following the negotiations and will make efforts to maximize the scope of possible import for its clients.
  4. An add-on service offered by Spherical in the course of the implementation project. Import is limited to the inventory variables that have a counterpart with the same business meaning in the UNFCCC reporting standard
  5. Spherical supports Sustainable Development Goals. We map all of our activities to SDGs, and we do not accept business that hampers or does not contribute to their achievement. In particular, we do not work with weapons producers, tobacco industry, primary extractors of fossil fuels and some other industries.
