Investment Policy Brief 27, 23 October 2025
Advancing Responsible Foreign Investment through a Legally Binding Instrument on Transnational Corporations and Other Business Enterprises
By Daniel Uribe Terán
Foreign Direct Investment (FDI) presents a complex dynamic, offering potential economic growth while posing significant risks of human rights abuses and environmental degradation. This policy brief considers that current voluntary frameworks, such as Economic, Social, and Governance (ESG) and voluntary due diligence standards, are insufficient to protect human rights, as they primarily focus on mitigating investor financial risk rather than preventing actual harm. Furthermore, the international investment regime, particularly the Investor-State Dispute Settlement (ISDS) mechanism, systemically undermines States’ sovereign right to regulate in the public interest. ISDS cases often penalise governments for enacting environmental, labour, and human rights protections, creating a “regulatory chill” that prioritises corporate profits over social welfare. The proposed Legally Binding Instrument (LBI) on business and human rights is presented as a necessary response to establish mandatory, enforceable obligations for corporations. This includes robust Human Rights Due Diligence (HRDD) and legal liability mechanisms, thereby rebalancing the system to ensure corporate accountability and align investment with sustainable development goals.
