This presentation introduces course participants to the fundamentals of calculating organizational greenhouse gas emissions. The segment covers the different strategies available for choosing the start year of a GHG inventory, and describes events that trigger the need for recalculation. The module details how structural changes such as mergers and acquisitions, the outsourcing of certain activities, and emergence of new data can alter the emission profile, and discusses procedures for restating figures. Narrated by industry expert Mark van Soestbergen, the course was produced by CarbonSolutions for use at higher education institutions in their academic and continuing education programs.
