Westchester County Airport (“the Airport”) is seeking qualified consultants to conduct a Scope 1, 2, and 3 Greenhouse Gas Inventory covering Calendar Year 2022 activities along with an air dispersion modeling effort to support the Airport’s environmental and sustainability commitments to the community. For years, the airport has been an environmental steward within the community, with a pioneering Airport Environmental Management System (AEMS) that complies with the ISO14001 Environmental Management Protocol. This study is seeking to update and enhance our understanding of the airport’s Greenhouse Gas (GHG) emissions and air quality impacts to inform our master planning efforts and further reduce our environmental impacts.
