The RETScreen Clean Energy Management Software (usually shortened to RETScreen Expert) is a software package developed by the Government of Canada. RETScreen Expert was highlighted at the 2016 Clean Energy Ministerial held in San Francisco. The Government of Canada's Treasury Board Secretariat uses RETScreen Expert as its greenhouse gas reporting tool for all federal departments and agencies required to report emissions.
