More and more companies are developing strategies to mitigate the environmental impact of their production processes by purchasing energy from renewable sources. These types of practices have made companies more attractive to investors, stakeholders and consumers, as well as achieving positive market positioning in their industry and increasing their competitive advantage.


In the Kyoto Protocol, 37 industrialized countries committed to reduce their emissions by 5% in its first period, which was from 2005 to 2008.  The protocol established the Clean Development Mechanism (CDM) as a means to promote sustainable development and social inclusion in developing countries.


The CDM works through projects whose objective is to counteract the effects of global warming, aimed at generating plants, which receive a CER for each MWh. CERs are the exchanged product within the CDM — they are an economic stimulus for companies and governments as they allow them to trade among themselves through the purchase and sale and auction of certificates, while collaborating to combat climate change and achieve a regulation of the emissions generated by their operations.


The purpose of Certified Emission Reductions (CERs) is to limit, reduce carbon emissions and report greenhouse gas (GHG) emissions.  Each CER is equivalent to one ton of CO2 and is part of the voluntary certificates, as they are not mandatory.


At Enel we offer you traceability about the origin of these certificates and we provide you with the necessary information about the environmental support behind each MWh you consume.
