Starting in 2021, multiple airlines will be forced to measure and offset their CO2e emissions through the CORSIA program promoted by ICAO. The airlines have not thought about how to involve passengers so that after measuring their emissions they can carry out compensation actions by acquiring carbon credits that are eligible by CORSIA. Neutralflight allows any passenger, tourist and / or executive, to offset the emissions of an airplane flight by combining science and blockchain technology, contributing to airlines with CORSIA compliance and rewarding their climate responsibility through an « eco miles program. « . In parallel, Neutralflight will allow airlines to reduce investments in carbon credits in order to comply with the CORSIA program, making passengers jointly responsible for the environmental impact generated by the industry in terms of GHG emissions.
