Particularities of the Legal Framework for the Mexican Emissions Trading System

Abstract

AbstractThis paper examines the legal bases for the mandatory regulation of the emissions trading system in Mexico. They are derived from the main international instruments on climate change: the United Nations Framework Convention on Climate Change (UNFCCC) and its ambitious objective, the quantifiable commitment of the Kyoto Protocol, and its tie to economic instruments. The Paris Agreement, the Nationally Determined Contributions (NDCs) and the market mechanisms regulated in Article 6, the implementation of which is essential to achieve the Agreement’s objectives are also part of this broad system. Legally, the international foundations of the emissions trading system are reflected at the national level. For these, the constitutional and legal bases underpin the current regulation of the mandatory market instrument. It aims to effectively reduce, in terms of costs, the greenhouse gas emissions from the most polluting economic activities, without replacing direct control measures. The core aspects of this system are highlighted from a national regulatory analysis, with special emphasis on the importance of a limited cap and its future reduction, as well as the legal nature of allowances that are allocated by the public administration to the regulated industries’ facilities.
