I'm not speaking about consensus with stakeholders per se. I'm speaking about the economists—including the most recent Nobel Prize-winning economists—the various expert panels that have been put together on sustainable financing, and the World Bank's initiative of the Carbon Leadership Pricing Coalition. We can point to leading economists, other scientists and social scientists around the world who, based on evidence, point to this as an effective lower-cost tool to reduce emissions.
I always mention the caveat that it's not the only tool, and it's important to note that there are a range of complementary measures.
