Allison Christians (McGill; Google Scholar) & Tarcísio Diniz Magalhães (Antwerp; Google Scholar), The Case for Taxing Away Unsustainable Profits, 91 Geo. Wash. L. Rev. 697 (2023):
When businesses offload environmental and social costs on the public, the resulting profits are windfalls extracted from current and future taxpayers. Prevailing regulatory and tax remedies have not only failed to eliminate such profiteering, but they have in fact incentivized it. To prevent some from receiving windfalls while everyone else bears the costs, profits can be distinguished between sustainable profits, when costs are internalized, and unsustainable profits, when costs are externalized. While the former would remain subject to the traditional corporate income tax, the latter should be completely taxed away with a surtax. A viable way to achieve this is to combine advanced mechanisms for measuring environmental and social damage across supply chains with classic and emerging legal techniques for differentiating categories of income for tax purposes.
Mobilized through the income tax system, these tools can be used to design a cutting-edge windfall tax on unsustainable profits. This Article makes the normative and practical case for doing so.
