Thank you for this question. This could absolutely be part of building sustainable global value chains. Stefano Ponte (2019 book “Business, Power and Sustainability in a World of Global Value Chains”) discusses the use of import/export taxes as part of innovative financing to support sustainable trade. Use of sustainability standards by regulators, public procurement policies, and import and export taxes could help to move towards sustainable trade to secure fairer contracts and more sustainable and biodiversity-friendly practices. Tax revenue could then be diverted towards diverse economic options.
