The Environmental Investigation Agency (EIA) – an independent, international, non-profit advocacy organization based in Washington, D.C. – recently identified China’s foam insulation industry as the source of the reappearance of the ozone-depleting gas, CFC-11 (EIA). The gas made a reappearance in the atmosphere two months ago in May 2018 after decades of steady decline, and scientists tried to find the source (NYT). The Montreal Protocol upgraded the partial ban on CFC-11 in 1987 to a complete ban in 2010, which included developing countries (BBC).

According to Avipsa Mahapatra of the EIA, “We were dumbfounded when out of 21 companies, 18 of them across China confirmed use of CFC-11,” (Guardian). Traders cited in the EIA’s report said companies in China mislabeled CFC-11 as HFC, or Hydrofluorocarbons to export to other countries (Telegraph). China provides about a third of the world’s spray foam insulation (BBC).
