(Reuters) – LONDON, June 30 (Reuters) – Rolls-Royce (RR.L), a British engineering business, has announced a collaboration with Shell (RDSa.L), an oil corporation, to cooperate on the development of sustainable aviation fuel (SAF), in line with both companies’ ambitions to achieve net zero emissions by 2050. On Wednesday, the two companies signed a memorandum of understanding (MoU), which Rolls-Royce claims would aid with the certification of 100 percent SAF for use in planes.
