3 solutions helping net-zero aviation take off

Aviation is responsible for almost 3% of global human-generated CO2 emissions and without urgent action this could increase to 22% by 2050, according to aviation-industry group Energy Transitions Commission.
Already, airlines belonging to the International Association of Travel Agents (IATA) have committed to reaching net-zero emissions by 2050. This will mean that the volume of CO2 emitted by airlines is balanced by the volume of emissions removed from the atmosphere.
The first net-zero flights are already taking off, with some using sustainable aviation fuel (SAF) and others offsetting flight emissions using a book-and-claim system for buying SAF.
Hybrid electric propulsion is being incorporated into a radical new type of power unit for aircraft.“New propulsion technologies will play an important role in achieving aviation’s net-zero goals, along with new aircraft designs and sustainable energy sources,“ Sabine Klauke, Chief Technology Officer at aviation manufacturer Airbus, told Avionics International.
A consortium of aviation and aerospace companies, including Airbus, Pratt & Whitney, GKN Aerospace and Collins Aerospace, have joined forces with the University of Stuttgart on the Sustainable Water-Injecting Turbofan Comprising Hybrid-Electrics (SWITCH) project.
The project combines hybrid-electric propulsion with water-enhanced turbofans (WET), which boosts flight efficiency by recovering water vapour from a plane’s exhaust and recycling it back into the engine’s combustion chamber.
Innovating to streamline operations and develop low-carbon solutions is an important part of aviation industry efforts to reach net-zero emissions, but more needs to be done. Policymakers, regulators and business leaders need to agree an action plan to bring about real change, supported by a policy framework that encourages greater adoption of SAFs and low-carbon solutions by airlines.
Initiatives like the World Economic Forum’s Clean Skies for Tomorrow programme brings together leaders from industry, government and civil society to help drive efforts to reach the net-zero emissions by 2050 goal.
Under this background, The 13th Annual Civil Aircraft Industry International Forum 2023 will be held in Chengdu City,Sichuan Province in April 25th-26th,2023.This forum aims to face the current severe international situation and the development challenges of the 14th Five-Year Plan and Vision 2035, mobilize all parties in the industry to work together, seize the opportunities and jointly promote the rapid development of China's civil aviation industry.
