The paper describes a new benchmarking method proposed for estimation of different biogas upgrading schemes. The method has been developed to compare the indicators of alternative biogas purification and upgrading solutions and their threshold values. The chosen indicators cover both economic and ecologic aspects of these solutions, e.g. the prime cost of biogas purification and storage, and the cost efficiency of greenhouse gas emission reduction. The proposed benchmarking method has been tested at "Daibe" - a landfill for solid municipal waste.
