Cover Photo: Composition by Marta Hernández The adoption of the Paris Agreement marks a before and after in the fight against climate change. It is the first international treaty in which all countries, depending on their capacities and national circumstances, agree to face this challenge. With this Agreement, the importance of working in concert, and under the same governance, is recognized to make it possible to reduce greenhouse gas emissions on a large scale, with the aim of maintaining the increase in global average temperature by below 2°C compared to pre-industrial levels and, even if possible, below 1.5ºC. This is the climate risk that the international community can accept. Thus, Spain is working on the preparation of a Climate Change and Energy Transition Law to meet the objectives set out in the Paris Agreement and within the framework of the European Union in the medium and long term in terms of climate and energy. The Law will promote the actions with the greatest capacity to achieve the commitments at the lowest possible cost, so that the energy and climate change policy favors economic activity, competitiveness and employment and ensures the financial sustainability of energy systems in Spain.
