Climate Change (CC) is a major issue of our century. Controlling the constraints of Greenhouse Gas (GHG) emissions through transformation into opportunities (Wettestad and Skjaerseth, 2007), in an organization to increase industrial production, has become a necessity. The main reason for this adoption was the effectiveness of energy management and responsible linkages that are being developed to determine the issues and opportunities of carbon finance for organizations. This article is part of the 21st Conference of the Parties 2015 (COP21) of the United Nations Framework Convention on Climate Change (UNFCCC) in France in Paris. In this regard, it is the ultimate opportunity to present an accurate diagnosis of GHG emissions quantification and a holistic review of Climate Change (CC) recommendations. This scientific contribution was, in fact, a natural extension of the 22nd Conference of the Parties (COP22) hosted by the Kingdom of Morocco in Marrakech in 2016. Indeed, COP21 and COP22 Are two crucial deadlines, since they must lead to a new international agreement on climate, applicable to all countries, with the objective of keeping global warming below 2 ° C. This article aims to analyze and study the performance of Carbon Finance in the EU Sustainable Finance Business Emissions Trading Scheme (EU ETS). We will develop our quantitative methodology for the econometric study of the EU Emissions Trading Scheme (EU ETS) for both phases [Phase I: 2005-2007 and Phase II: 2008-2012] (Alberola, Chevallier and Cheze, 2009). The increasing complexity of Climate Change (CC) challenges creates a systemic view of EU ETS companies and a macroeconomic framework for environmental issues. In this context, we will develop our quantitative methodology adopted for the econometric study of the EU Emissions Trading Scheme (EU ETS) for the two phases of the EU ETS [Phase I: 2005-2007 and Phase II: 2008 -2012]. In the same direction, this scientific research addresses the thrilling question: "What are the responsible issues and sustainable and sustainable opportunities for the adoption of carbon finance for EU ETS companies for the development of a"2 °C?", In order to facilitate climate decision-making and to limit CO2 emissions. The real challenge is to contain the increasing complexity of Climate Change (CC) in a way that is compatible with the warming scenario limited to + 2 ° C. The development of the EU ETS is the reticular example of this turning point.
