AIG is a major insurance provider to fossil fuel companies, and has billions invested in the industry. AIG is the largest coal insurer outside of China, and one of the few still able and willing to underwrite new, multi-billion-dollar coal projects. The company is also among the top three insurers of oil and gas projects. While at least 37 insurers have limited or ended coal underwriting, AIG stands out as a global laggard with no restrictions on insurance for the coal sector. AIG has also failed to rule out insurance support for destructive fossil fuel expansion projects, including the Adani Carmichael coal mine and the Trans Mountain tar sands oil pipeline.
