The five virtual sessions that made up this course were held in October and November 2021, with the aim of strengthening technical capacities for the design of marginal abatement cost curves (MACC curves) for industrial sectors, who participate in the Emissions Trading System (ETS).

This event arose as a coordination between the 2030 Agenda Climate Change Working Group and the GIZ SiCEM project, born of the need to highlight the benefits of a correct interpretation of the MACC curves, since these allow– through a graphical representation –the identification of optimal mitigation measures for each organisation, according to their scope and technical-economic limitations.

The theoretical-practical classes had an average capacity of 30 participants from sectors regulated by the Mexican Emissions Trading System, who had the opportunity to immerse themselves in fundamental economic concepts for the correct understanding of the MACC curves, and other practical cases. These sessions also included interactive spaces that encouraged collaboration among attendees, in order to find solutions to the proposed exercises. The course work resulted in very enriching analyses, showing that the participants supported the knowledge brought forward at the event.

The consulting team of Carbon Trust Mexico was in charge of the sessions and, thanks to its expertise on the subject, it was possible to guide the participants in the implementation of the MACC curves, with examples in each of their industrial sectors.

The interest of the industrial sector in this issue reflects the commitment to making well-informed decisions aimed at mitigating GHG within their organisations, as well as the co-benefits that such actions represent.
