Absolutely. Externality as an economic theory has been a major problem in terms of the environmental process. Many of the true costs of doing business in, for example, fossil fuels before carbon pricing, were externalized, and that reflected neither the cost of doing business nor the cost to consumers, but we ultimately pay for that in terms of climate-related disasters, extreme weather and so on. Reducing those externalities using the principle of internalization of cost, polluter pays and a lot of things like that will help us have a full picture.
As I said, once you do that, and once you internalize social, environmental and economic costs into a comprehensive model, you will see more of a dovetailing between the environment and economy, as opposed to looking at it mainly from a financial point of view, where one could profit by externalizing costs to society and the environment. From a full economic point of view, it's not a good news story. It may be profitable for the entity involved, but it may not be economically or environmentally sound for society as a whole.
Cost internalization and the quantification of some of these ecosystem services and other natural assets that we have—and nature-based solutions come into play here too—are all emerging and critically important issues. As someone mentioned, one of the biggest impacts on the environment each year by governments is its budget decisions, not just the regulatory decisions of the environment department or the natural resources department in a given jurisdiction. Once we look at those together, we'll be on a good path.
