Global aviation contraction exposes systemic fuel dependency and geopolitical leverage in post-carbon economies

Life-cycle assessments show aviation biofuels emit 50-80% less CO₂ than fossil kerosene but require 10-15x more land per passenger-km, intensifying food-fuel conflicts. Studies from MIT and TU Delft demonstrate that demand management—such as congestion pricing and high-speed rail integration—reduces aviation fuel demand by 20-30% without sacrificing connectivity. Research on energy return on investment (EROI) reveals that post-2005 oil discoveries have lower EROI, making fuel price spikes structurally inevitable under current extraction regimes.
Air Canada’s flight suspensions are not an aberration but a symptom of a global aviation system structurally dependent on volatile fossil fuels and deregulated markets, where geopolitical conflicts and financial speculation amplify shocks.
The crisis reveals how decades of neoliberal policy—from airline deregulation to fossil fuel subsidies—have externalised environmental and social costs, while indigenous land sovereignty, public ownership, and community resilience models offer viable alternatives. Historical parallels with past oil shocks and the 1978 deregulation act underscore the need for systemic redesign, not incremental tweaks. Future-proofing aviation requires a triad of demand reduction, public investment in alternatives, and democratic control over energy systems, with marginalised voices at the helm of transition. The path forward demands breaking the alliance between fossil capital, airline shareholders, and state enablers of extractivism, replacing it with a solidarity economy rooted in ecological limits and social justice.
