This report by the Stockholm Environment Institute critiques the UK Department for Transport's (DfT) cost-benefit analysis regarding the expansion of Heathrow Airport. The authors argue that the DfT's projection of positive net benefits relies heavily on 'generated user benefits'—a theoretical construct of consumer surplus—which they claim is based on speculative and biased assumptions about future airfares, fuel costs, and passenger demand.

This 2004 policy paper by the Stockholm Environment Institute argues that the rapid growth of global aviation is unsustainable due to its significant contribution to climate change and local pollution. It highlights that aviation's radiative forcing makes its emissions three times more damaging than ground-level CO2 and criticizes government subsidies that artificially stimulate demand. The report recommends a shift toward demand management, including the internalisation of external costs, shifting short-haul passengers to rail, and implementing strict noise and emission limits at airports.

This September 2020 report by the Stockholm Environment Institute (SEI) provides practical guidance for organizations to track, report, and reduce business air travel emissions. Based on the TR2AIL project, which involved interviews at SEI and the University of East Anglia, the document outlines strategies for setting emissions targets, implementing decision-support tools, and fostering an organizational culture that prioritizes lower-carbon travel alternatives.

A policy brief by the World Resources Institute arguing that the United States should shift its sustainable aviation fuel (SAF) strategy away from food and feed crops to avoid increasing food prices and environmental degradation, focusing instead on waste biomass, captured carbon, and clean hydrogen.

This research paper discusses the rapid growth of the biofuels industry and the resulting debate over whether these fuels drive tropical deforestation, particularly as the aviation and maritime sectors seek to meet carbon reduction targets.
