GHG Protocol updates are reshaping the outlook for GHG reporting, including a move toward a consolidated corporate standard, with an exposure draft expected in 2027 and a final standard planned for 2028. This episode covers the updated roadmap and developments related to scope 2, scope 3, book-and-claim market instruments, the Land Sector and Removals Standard, and California SB 253, as well as steps companies can take now as these requirements and proposals continue to evolve.
