Aviation and Sustainability

The document examines the environmental and social impacts of the aviation industry, noting that rapid growth in passenger and freight demand cancels out technological efficiency gains. It highlights the sector's contribution to climate change through greenhouse gases and radiative forcing, as well as local impacts like noise and air pollution. The authors propose a demand management strategy based on three pillars: internalising external costs via emission charges, shifting short-haul passengers to rail, and substituting physical travel with electronic communication. The paper concludes with nine specific policy recommendations, including a ban on night-time flights and the adoption of an 'environmental bubble' concept for airports.

• Global aviation demand grew by 9% per annum over the last 50 years, and while the rate may slow to 3-7%, the number of aircraft is expected to nearly double by 2022.
• Aviation's impact on climate change is amplified because emissions are released at high altitudes, resulting in a radiative forcing effect that makes them approximately three times more damaging than ground-level emissions.
• Aviation is projected to account for up to 15% of the total contribution to climate change by 2050, yet international aviation emissions are currently excluded from national inventories and the Kyoto process.
• Technological improvements in fuel efficiency are insufficient to offset the growth in traffic; consequently, consumption cancels out technological gains.
• Aircraft noise significantly impacts public health, particularly children, with one in eight people in the UK affected; chronic exposure is linked to impaired reading performance and increased heart rates in children.
• The aviation industry is heavily subsidised by taxpayers and the absence of fuel taxes, which creates an artificial environment of cheap fares that further stimulates demand.
• Short-haul flights (under 500km), which make up 45% of all EU flights, are the least fuel-efficient per passenger kilometre and are primary candidates for modal shift to rail.
• Internalising external costs through emission charges is proposed as a feasible way to reduce pollution without violating the Chicago Convention, as it is not a tax on fuel.
• Electronic substitution, such as videoconferencing, can significantly reduce business travel costs and emissions, with some estimates showing costs reduced by up to 80% for certain destinations.
