Sustainability Initiatives

Our mission is to create a cleaner, quieter and more sustainable airport that respects the extraordinary natural environment of the Roaring Fork Valley. We are committed to reducing noise and air pollution, improving energy efficiency, lowering our carbon footprint, and protecting the wildlife habitat, open spaces and surroundings that make this community unique.

Airport Master Plan included sustainability considerations

Voluntary Fly Quiet Noise Program began

Noise baseline established

ASE’s first Greenhouse Gas (GHG) emissions inventory

Airport Operations Center opens

Includes natural materials and affordable housing

National Environmental Policy Act (NEPA) Environmental Assessment (EA) for ASE runway extension

This included 2012 and 2017 forecasts: no exceedances

ASE GHG emissions inventory

ASE awarded “FAA Northwest Mountain Region Sustainability Award”

APU/GPU reduction alternatives

ASE GHG emissions inventory

NEPA EA – included 2023 and 2033 forecasts; no exceedances

ASE GHG emissions inventory

FAA published a Finding of No Significant Impact/Record of Decision for the runway and terminal area improvement projects. The document included specific sections on air quality and climate/greenhouse gases, under projected operations.

Re-evaluation of NEPA EA; no exceedances

ASE GHG emissions inventory

ASE GHG emissions inventory

ASE Vision Committee develops the Common Ground Recommendations

ASE GHG emissions inventory (joint inventory due to the COVID-19 pandemic)

ASE GHG emissions inventory

Fly Quiet Program refreshed and updated with new metrics and additional monitors

Sustainability embedded into design of the Terminal Modernization Program

Air quality measurements begin (for 365 days)

Transitioned all indoor lighting to LED

Transitioned all outdoor lighting to LED

Transitioned all airfield lighting to LED

Installed occupancy sensors in some areas of the Airport Operations Center (AOC)

2019 energy audit

Installed smart thermostats in Terminal and AOC

Began to utilize on-site solar where feasible (e.g., crosswalks and parking lot lighting)

Began transitioning fleet vehicles to electric/hybrid alternatives (in 2023 ASE purchased first alt fuel vehicle, in 2024 purchased two more)

Installed 10 electric vehicle (EV) chargers at the AOC and two at the Terminal for employee use

Atlantic Aviation has begun the transition to electric Ground Support Equipment (eGSE)

Began procuring Sustainable Aviation Fuel (SAF)

Emissions Modeling : Use of computer modeling to quantify the amounts of emissions in a specific study area based on specific sources (i.e., buildings, Ground Support Equipment [GSE] , aircraft)

Emissions Monitoring (Field Measurement) : Use of measuring equipment to identify the specific quantity of a pollutant that an individual might breathe at a specific location at a specific point in time (i.e., µ/m3 [micrograms per cubic meter – physical weight of pollutant to specific volume of air] or ppm [parts per million: ratio of pollution gas molecules to total molecules of air])

Emission Reduction Action Plan (ERAP) : Plan for implementing emission reduction measures within operations, facilities, management, policy, capital, and development for Aspen/Pitkin County Airport.
