The Qantas Group says it will aim to reach net zero carbon emissions by 2050 in a major expansion of the airline’s commitment to a more sustainable aviation industry. The  carrier will double the number of flights being offset and cap net emissions from next year onwards. The Australian flag-carrier will invest $50 million over 10 years to help develop a sustainable aviation fuel industry. The announcement claims that Qantas is the only airline group to commit to cap its net emissions at 2020 levels, and the second to commit to net zero emissions by 2050. Alan Joyce, CEO, said Qantas has already made good progress, especially in investing in newer aircraft that have a much smaller carbon footprint. “We want to do more and faster,” he said. Qantas, Jetstar, QantasLink and Qantas Freight will offset all growth in emissions from domestic and international operations from 2020. This includes offsetting all net emissions from Project Sunrise, the carrier’s plan to operate nonstop flights from the east coast of Australia to London and New York, should the project proceed.
