The Emissions Trading System (ETS) is one of the carbon price mechanisms that has accelerated the mitigation of greenhouse gas (GHG) emissions over the past decade. It works using the “cap and trade” principle. A limit is imposed on emissions from one or more economic sectors, and regulated facilities are granted a limited number of emission rights that they can trade among themselves, to carry out their compliance obligations in a cost-effective manner.

There are factors that ensure the proper functioning of an ETS; among them, stability in carbon prices and a supply of emission rights that is consistent with market demand. The current economic recession caused by COVID-19 has altered these two variables and has presented significant challenges for the more than 20 ETS operating around the world. It is important to be aware of the global strategies to overcome these challenges and identify lessons learned that could strengthen the ETS Test Program in Mexico, in force since January 2020.

According to ICAP data, there was a significant drop in carbon prices in California and Quebec in March, as well as in the European Union (EU), where it fell from an average of 25 EUR to 15 EUR. In Switzerland, the auction of emission rights was even rescheduled due to the price drop. Commercialization of emission rights in the ETS of the EU is affected by oversupply, which can lead to a reduction in public revenue from auctions, and discourage investments in mitigation technologies.

Countries such as Canada, China, Korea, and Switzerland have responded to these impacts by postponing compliance and reporting dates, while the European Commission anticipates a reduction in the number of emission rights available within the Market Stability Reserve. On the other hand, Poland and the Czech Republic have suggested a review of the EU’s ETS conditions.

Strategies implemented by other countries help inform Mexico of the risks faced by ETS and their possible solutions. The project “Preparation of an Emissions Trading System in Mexico” (SiCEM), implemented by the Deutsche Gesell¬schaft für Internationale Zusammenarbeit (GIZ) GmbH will follow the evolution of the system’s global situation closely.
