A quiet revolution is taking place in the financial industry. According to the United Nations Environment Programme, sustainable development is increasingly being integrated into financial decision-making. The European Union has been rather passive so far in this transformation, but financial regulators in a number of countries are leading the charge. The revolution may be quiet, but it is getting louder. Fossil-fuel companies are increasingly being delegitimized. At the same time, investors are starting to understand that paying attention to climate risk is an integral part of a sound investment strategy that seeks to minimize risk and help to promote financial stability.
