By virtue of enabling clean energy, RETScreen indirectly contributes to a substantial reduction in greenhouse gas emissions—a reduction conservatively estimated at 20 million tonnes per annum. It is also estimated that RETScreen has helped spur the installation of at least 24 GW of installed clean energy capacity worldwide with a value of approximately $41 billion.
Kwa sababu ya kuwezesha nguvu safi, RETScreen inachangia kwa njia isiyo dhahiri upunguzaji mkubwa katika utoaji wa gesi katika nyumba za vioo-upunguzaji unaokaridiwa kuwa tani milioni 20 kila mwaka ifikapo mwaka 2013. Na ifikapo mwaka 2013, inakadiriwa kuwa RETScreen itakuwa imeshasaidia msukumo wa kuanzisha angalau uwezo wa GW 24 wa nguvu safi ulimwenguni kote ikiwa na thamani ya $41 bilioni.
