The world has a significant climate opportunity within its grasp that can bring fast results at low-cost, according to Institute for Governance & Sustainable Development (IGSD) President, Durwood Zaelke, who last Thursday addressed the European Parliament’s Committee on the Environment, Public Health and Food Safety (ENVI). Using the Montreal Protocol ozone treaty to phase down production and use of hydrofluorocarbons (HFCs) – potent greenhouse gases used in refrigeration, air conditioning, and foam-blowing applications for insulation – could result in mitigation of 100 billion tonnes of carbon dioxide-equivalent by 2050, at a cost of 5-10 cents per tonne.
