In addition, the MAC transformed its quarterly MSP Noise Oversight Committee public information meetings into listening sessions, with a greater focus on providing a forum for airport neighbors to express concerns and get their questions answered. The MAC also created a Noise Basics video and fact sheet series to help explain various aspects of aircraft noise. Additionally, the MAC launched a new interactive reports site, with graphics to help simplify noise-related data and avenues to dig deeply into the data if desired.

The MAC was recognized nationally for developing an innovative way for the industry to measure impacts of optimized profile descents at a local airport level. Endorsed by the Noise Oversight Committee and the MAC, optimized profile descents occur when pilots keep the throttle pulled back for a continuous descent rather than using more traditional procedures that involve power adjustments and descending in steps. The MAC estimates that airlines burn 2.9 million fewer gallons of fuel per year using optimized profile descents, emitting 28,465 fewer metric tons of carbon dioxide into the atmosphere. In addition, the MAC achieved Level 2 Carbon Accreditation from an industry program that recognizes airports that commit to reducing their emissions by making investments in technologies, incentives and stakeholder engagement. As part of the environmental analysis of improvements at Lake Elmo Airport, the MAC expanded opportunities for community members and airport users to gain information and engage in the process. The enhanced public process will serve as a template for similar efforts in the future. 24 25
