Climate change is an increasingly pressing concern for the public at large. It may have serious implications for inflation, financial stability and growth. Within our remit, central banks and financial sector supervisors are playing a significant role in tackling it and smoothing the ecological transition. In addition, the Banco de España has initiated a series of actions to reduce the impact of its activity on the environment, adopting a firm commitment in the form of its Corporate Sustainability Policy. In short, climate change is a problem that affects us all.
