Beyond carbon dioxide, ICAO Aviation Climate Week 2026 will examine the impact of non-CO₂ aviation emissions such as contrails and nitrogen oxides.
While these emissions have historically received less attention, emerging research suggests they may significantly influence climate warming.
Dr. Chinwe Egbunike, an environmental policy researcher at the University of Lagos, said African regulators must begin integrating non-CO₂ considerations into aviation policy.
“The science is evolving. If global standards tighten, African airlines will need to upgrade operational efficiency,” she said.
She added that improved air traffic management and route optimisation could help mitigate these emissions without massive capital investment.
An official at the Nigerian Airspace Management Agency confirmed that digital airspace modernisation efforts are ongoing.
“Efficient routing reduces fuel burn and emissions. Technology is key,” the official said.
Industry observers expect ICAO Climate Week to clarify how non-CO₂ emissions will be incorporated into global compliance frameworks.
Egbunike noted, “Africa should focus on efficiency reforms now to avoid future penalties.”
