Strong policies on black carbon can sharply cut glacier melt, says World Bank study Updated: Updated: June 03, 2021 22:17 IST Enacting new policies can achieve benefits over the projected 23% reduction in Black Carbon as a result of ongoing efforts. Share Article AAA The research report covers the Himalaya, Karakoram, and Hindu Kush (HKHK) mountain ranges, where, it says, glaciers are melting faster than the global average ice mass. | Photo Credit: Getty Images/iStockphoto Enacting new policies can achieve benefits over the projected 23% reduction in Black Carbon as a result of ongoing efforts. Black carbon (BC) deposits produced by human activity which accelerate the pace of glacier and snow melt in the Himalayan region can be sharply reduced through new, currently feasible policies by an additional 50% from current levels, new research by World Bank (WB) specialists has said.
