Las políticas europeas en materia de cambio climático en el contexto internacional.

The European Union has pioneered the adoption of binding greenhouse gas emissions reduction targets and measures to address the climate change challenge for more than a decade. Amongst them, the European Union Emissions Trading System plays a central role. This article addresses the evolution of European climate policies, from the first emission reduction targets that were assumed under the Kyoto Protocol to the recent adoption of the 2030 climate an energy framework. Due to its importance, special attention is paid to the European Union emissions trading system, an essential tool to meet these targets at regional level and a cornerstone of European climate policies, now working for more than ten years. In this context, the European Union emissions have significantly decreased, although the effort ahead is, without any doubt, still remarkable. [ABSTRACT FROM AUTHOR]
