We also need to open ourselves up for global carbon markets. Article 6 means that we can in fact—and the Paris Agreement will allow us to—do bilateral agreements if we can't come to an agreement to establish global carbon markets. And there is a group of countries that are just philosophically opposed to setting up international carbon markets. International carbon markets make sense if you accept that global warming is an international problem, and I think it is; it is not confined to a country's borders. So nor should it attempt to lower emissions either by reducing emissions in the first place or sequestering them. We should be able to be open for that.
