We do actually have a comprehensive model, as part of our national emissions inventory, pertaining to stored carbon. It's work that we undertake with other departments and agencies. We just released the most recent update a week or two ago. We have comprehensive models for forest carbon that are worked on in Canada but with international partners, as the minister indicated, to fit into the development of those land use and land use change international rules, but more fundamentally to understand the behaviour of natural systems in a changing climate so we can measure, monitor, and model and then adjust policy and work with provinces and territories and others to find ways to more effectively store carbon in a natural system.
