For more than 25 years, we have produced this annual report to help airport management teams, investors, finance sector analysts, and airlines gain a better understanding of how airports worldwide stack up in terms of relative operational and financial efficiency. The report compares the sum of aeronautical arrival and departure charges at 50 of the world's busiest airports for a sample of eight aircraft that are most predominant in airline fleets. The report also provides an extensive historical background of aeronautical charging systems and methods of airport price regulation. In addition to being a valuable benchmarking resource, the report is frequently used to inform pricing discussions between airports, regulators, and airline users.

Reducing carbon emissions while scaling up our cities to meet the demands of urban growth has implications for how we design, construct, operate and maintain buildings. Find out why “going green” needs to be at the top of your priority list and the solutions that will get you there.

COP26 provided the platform to raise the critical need to speed up the green agenda. But how will we actually get there, and truly make green work for everyone? This latest report, published in the U.K. in collaboration with London Transport Museum, Gowling WLG and Thales sets out recommended steps for how governments and businesses can drive the green industrial revolution. It details how some of the hurdles faced can be overcome, unlocking wider opportunity, and ensuring it works for everyone.

In this issue, we’re shining a light on adaptation, with Article 7 of the Paris Agreement defining the global goal of enhancing adaptive capacity and resilience and reducing vulnerability with a view to contributing to sustainable development. While significant actions are underway to limit global warming through carbon reduction measures, countries, cities, communities and businesses also need to accelerate their efforts to adapt to climate change impacts that are already occurring, as well as prepare for future climate change scenarios.

The Transportation Research Board of The National Academies published ACRP Report 66: Guidebook for Considering and Evaluating Airport Privatization, for which LeighFisher was the primary research consultant. The guidebook was designed to assist U.S. airport owners, policymakers, and other relevant stakeholders consider and evaluate the potential advantages and disadvantages of implementing various approaches to airport privatization.
