As Colombia prepares to host the world’s first Global Conference on Transitioning Away from Fossil Fuels this April, a powerful coalition of more than 220 leading economists, legal scholars, and policymakers is calling on President Gustavo Petro to take bold action.

In a public letter presented on Monday in Bogota, promoted by the Center for Economic and Policy Research, Boston University Global Development Policy Center, and the NGO Public Citizen, signatories including Nobel laureate Joseph Stiglitz, economist Thomas Piketty, and Paris Agreement architect Laurence Tubiana urge Colombia to lead an international effort to dismantle investor-state dispute settlement (ISDS), a system embedded in thousands of trade and investment agreements worldwide, including in Colombia.

As of 2025, Colombia had over $13 billion in pending ISDS charges, about one-seventh of its annual budget. To compare, it would cost $42 billion to fully implement the 2017 peace agreement, while it would cost about $25 billion for the country to have universal healthcare. Without confronting ISDS, meaningful state action may be impossible.

ISDS, sometimes referred to by economists as “litigation terrorism,” allows foreign corporations to sue governments in private arbitration tribunals over public-interest regulations, including environmental protections. It has become a powerful weapon for multinational firms to challenge policies aimed at phasing out fossil fuels, often resulting in massive financial penalties for states that attempt to regulate or transition their economies.

If the world is serious about confronting the climate crisis, it must also confront the legal and economic structures that entrench fossil fuel dependence. Dismantling ISDS is a precondition for meaningful change.

“Investor-State Dispute Settlement has a track record of being very favorable to foreign corporations at the expense of local communities, the environment, and economic development,” Stiglitz noted. For countries seeking to move away from fossil fuels, ISDS creates a chilling effect; governments hesitate to enact ambitious climate policies for fear of triggering billion-dollar lawsuits.

Stiglitz added that "investor-state dispute settlements don’t just mean growing debt burdens for countries: they are also a barrier to action on the climate crisis.”

Colombia is especially exposed. The country has 129 oil and gas projects covered by ISDS provisions, leaving it vulnerable to a wave of potential claims as it pursues its energy transition.

Petro has signaled his intent to reduce reliance on these mechanisms, but has yet to follow the path of countries such as South Africa, India, and Indonesia, which have terminated ISDS-linked agreements outright after concluding they undermined national sovereignty.

Across Latin America, ISDS has quietly transferred enormous public wealth to foreign........
