Mark Dunkerley, Hawaiian Airlines’ president and CEO, holds the plaque presented to the airline for earning the aviation industry’s first-ever verified carbon credits. Participating in the recent ceremony was Hawaii Governor Neil Abercrombie (r) and Hawaii State Senator J. Kalani English. Hawaiian Airlines earned the honour for its efforts to reduce CO2 emissions. Since 2005, Hawaiian has used an eco-friendly engine washing technology on its aircraft, the result of which has been a reduction of nearly 22,000 metric tons of CO2 emissions overall since then. This is the equivalent of removing 700 cars from the roadways annually.
