International investment agreements are coming under increasing fire for the threat that they pose to the global phasing out of fossil fuel energy sources. Foreign investors can challenge state measures addressing climate change via investor-state dispute settlement, which can lead to huge compensation awards that may deter states from taking such action. This piece discusses how investment law can be problematic in regard to climate change measures and calls for states to acknowledge this threat as they move forward with reforms to the international investment law regime.
Recently, it was announced that German energy company RWE is suing the Netherlands for €1.4 billion in response to the country’s decision to phase out coal energy. The case was brought via the investor-state dispute settlement (ISDS) provisions of the Energy Charter Treaty (ECT), a 1994 multilateral treaty for energy industry cooperation across borders. ISDS is a dispute settlement mechanism through which foreign investors can bring claims directly against host states if investors consider that they have been treated unfairly. The ECT has come under fire in recent years for being a threat to state efforts to switch to renewable energies, because it enables fossil fuel companies to sue states that make regulatory changes aimed at reducing carbon emissions. It has been reported that suits under the ECT could cost taxpayers up to €1.3 trillion by 2050 and protect up to 216 Gt of carbon, which exceeds one-third of the global carbon budget that can be emitted if we are to keep global warming below 1.5 degrees by 2100.
