The 2022 World Investment Report by the United Nations Conference on Trade and Development (UNCTAD) highlights that global foreign direct investment (FDI) flows recovered to pre-pandemic levels in 2021, reaching $1.6 trillion. Cross-border deals and international project finance were particularly strong, driven by loose financing conditions and infrastructure stimulus. However, the recovery of greenfield investment in industry remains fragile, especially in developed countries. The report also examines the impact of international tax reforms on FDI and sustainable investment. It concludes that tax reforms can promote sustainable investment and support the transition to a low-carbon economy, but they must be designed carefully to avoid unintended consequences. The report emphasizes the importance of cooperation among countries to ensure a level playing field for investors and to promote sustainable development.
