Coral Davenport: U.S. Moves To Reduce Global Warming Emissions
The Obama administration on Tuesday announced a series of moves aimed at cutting emissions of hydrofluorocarbons, or HFCs, powerful greenhouse gases that contribute to climate change. The White House has secured voluntary agreements from some of the nation’s largest companies to scale down or phase out their use of HFCs, which are factory-made gases used in air conditioning and refrigeration. Coca-Cola, Pepsi, Red Bull, Kroger, Honeywell and DuPont, the company that invented fluorinated refrigerants, have agreed to cut their use and replace them with climate-friendly alternatives.
Over all, the administration estimated that the agreements announced on Tuesday would reduce cumulative global consumption of HFCs by the equivalent of 700 million metric tons of carbon dioxide through 2025. That is about 1.5 percent of the world’s 2010 greenhouse gas emissions, or the same as taking 15 million cars off the road for 10 years. “Every drumbeat in this symphony helps. It drives it along. This is part of that drumbeat,” said Durwood Zaelke, president of the Institute for Governance and Sustainable Development, a research organization. “The benefits from cutting non-CO2 come much faster,” he added. “CO2 is like a supertanker – you can stop it, but it keeps drifting for a long time. Cutting HFCs are like stopping a steamboat. You stop it and that’s that.”
