Nominated by the U.S. to the United Nations Framework Convention on Climate Change’s (UNFCCC) Roster of Experts, Marian provides GHG inventory systems training and technical assistance to clients worldwide.

A lead reviewer for the UNFCCC’s National Communications and Biennial Reports, Marian supports expert review teams from the U.K., Belgium, and Denmark. She is a previous technical working group member and chapter lead for the WRI Greenhouse Gas Protocol’s Mitigation Goal Standard and the technical working group for two volumes of the Initiative for Climate Action Transparency. Marian also contributes to numerous additional GHG protocols and calculators for federal agencies, corporate clients, and other organizations.
