Short summary

Emissions from fires are tallied in Canada's National Forest Carbon Monitoring Accounting and Reporting System. Mapped fire extents and regional carbon stock estimates are used, but a fixed and high fire severity is assumed. This paper improves on existing methods by calculating fire emissions based on mapped fire severity. This new method compares well against independent measurements for the 2023 fires in Canada.
