A method for obtaining GHG reduction credits associated with GHG reduction efforts, the method comprising grouping a plurality of sites chosen according to given GHG related parameters into a given community cluster, the GHG related parameters comprising distinct types of common potential GHG reduction efforts profiling GHG reduction efforts provided by a corresponding site providing an opportunity for converting the GHG reduction efforts into GHG reduction credits upon acceptance of the opportunity for converting and performing of the GHG reduction efforts, accounting the performed GHG reduction efforts and the converted GHG reduction credits for each performing site and returning a portion of the converted GHG reduction credits to each site. The method enables aggregating small quantities of common and generic potential GHG reduction efforts of small final emitters together to provide optimal management and monetization thereof while enabling to manage a plurality of different types of common GHG reduction efforts.
