Accounting for Emission Allowances under GAAP and IFRS. I have researched this topic but am finding not information that show either the FASB or the IFRS has written any final guidelines on this subject? Is anyone aware of any such guidelines having finally been drafted by either the FASB or IFRS? If so would you have a url for the guidelines? If not what is the current accounting practice per the FASB as well as the IFRS, for the purchase of Emission Allownaces? Thanks
