Last October, the International Air Transport Association (IATA), passed a resolution in support of net-zero carbon emissions by 2050 during its annual meeting. In November, Iberia and Repsol have completed the Madrid–Bilbao route with biofuel produced from waste at the Petronor Industrial Complex. The use of biofuels and the improved energy efficiency has resulted in a reduction in emissions of 1.4 tonnes of CO2.
