Synthesis of Information Related to Airport Practices. Topic S02-20. Lessons Learned from Airport Greenhouse Gas Reduction Efforts

Some airports have undertaken initiatives to reduce greenhouse gas (GHG) emissions as directed by governing boards and stakeholders to address global climate change. Airports Council International – North America (ACI-NA) named reducing GHG emissions as one of its members’ top priorities. GHG reduction projects have been implemented at various airports, and ACRP reports have been published on the range and scope of airport projects that can affect GHG emissions. ACRP Report 43, ‘Guidebook of Practices for Improving Environmental Performance at Small Airports’ documented case studies at small airports with projects that impacted greenhouse gas emissions. ACRP Report 56, ‘Handbook for Considering Practical Greenhouse Gas Emission Reduction Strategies for Airports’ documented 125 strategies that can reduce GHG emissions and ranked them based on financial considerations, implementation considerations, and potential impacts on GHG emissions. Since this report came out in 2012, projects have taken place utilizing its methods at airports of varying sizes. However, the outcomes of these projects have not been compared to their expected effectiveness and the range of success has not been examined. Airports are at different stages in evaluation of GHGs and GHG reduction efforts. As nodes supporting a complex web of aircraft movements, technical operations, and surface access transport, airports address their GHG emissions in a variety of ways. Some airports have also begun analyzing emissions from tenants and others that use or visit their facilities. The Airport Carbon Accreditation (ACA) scheme is one way that contains four levels of certification—Mapping, Reduction, Optimization, and Neutrality. With the second of four levels of ACA certification being GHG Reduction, understanding the types of projects that have been most successful in the past is vital. Currently, there are six airports in the U.S that have achieved a level of Airport Carbon Accreditation (ACA), with four of these airports achieving carbon Reduction status. Lessons can be learned from these efforts in addition to those from the 192 airports worldwide that have achieved ACA certification. It is also important to understand the differences in effectiveness of various strategies based on the region. Results from projects can vary based on meteorological patterns, population, surrounding land-use, etc. This study will synthesize results from projects at a range of airports pertaining to the implementation of GHG reduction initiatives, and would significantly benefit airports considering projects in the future. The audience for the report is airport staff members responsible for planning and implementing GHG reduction programs. The product of this research will be a concise synthesis of current practice that reports on: (1) A detailed literature review describing categories of projects aimed at reducing GHG’s at small, medium, and large airports across climatic regions. (2) Data collection via survey/interview from airport practitioners at small, medium, and large airports across climatic regions who have experience implementing GHG reduction projects to document their knowledge on processes leading to effective outcomes. (3) Identification of project types by airport specific conditions such as size, region, and climate and levels of success. (4) Identification of how airports determine the cost effectiveness GHG reduction strategies chosen and implemented. (5) Gaps in knowledge and further research activities to improve implementation of GHG reduction projects at airports.
