ANALYSIS: With more of us getting back on planes, can aviation go greener?
As the climate change threat rapidly worsens, can aviation make the transition to a low-carbon future — and perhaps even reach net zero emissions? The significant technological and energy disruption on the horizon for the industry suggests such a future is possible.
But significant challenges remain. Achieving a net zero aviation sector will require a huge collaborative effort from industry and government — and consumers can also play their part.The aviation sector's progress in cutting emissions has been disappointing to date. For example, in February last year,on the world's largest 58 airlines found even the best-performing ones were not doing anywhere near enough to cut emissions.
Most recently, at the COP26 climate change summit in Glasgow, the industry merely reasserted a commitment to a plan known as theThe scheme relies on carbon offsetting, which essentially pays another actor to reduce emissions on its behalf at lowest cost, and doesn't lead to absolute emissions reduction in aviation. The scheme also encourages alternative cleaner fuels, but the level of emissions reduction between fuels varies considerably.
Governments have generally failed to provide strong leadership to help the aviation sector to reduce emissions. This in part is because pollution from international aviation is not counted in the emissions ledger of any country, leaving little incentive for governments to act.Aviation is also a complex policy space to navigate, involving multiple actors around the world.
