Program Overview

Commercial, passenger air travel is responsible for around 3% of greenhouse gas (GHG) emissions on both global and U.S.-based scales1With technological and new fuel source adoption, the International Council on Clean Transportation suggests that aviation GHG emissions can be reduced to a significant enough degree to meet standards set through the 2015 Paris Agreement by 20502.

This EPN Breakfast program will explore commercial-based air travel and aviation technology specifically, as well as the communication strategies used in the industry to address regulator and consumer interests/concerns about GHG emissions.  

Please join fellow environmental professionals and sustainable aviation experts to learn about Sustainable Aviation Fuels (SAF), the significant technological barriers (power density and energy density for fuel sources) to creating a “sustainable” aviation industry, the greatest opportunities for GHG reductions in the aviation industry, GHG reporting and communication with commercial flight passengers.

The moderated panel discussion will connect the environmental community, consumers concerned about both GHG emissions and air travel, and aviation experts to identify how industry is responding to these challenges and opportunities. This event will inspire and enhance the knowledge base of professionals, students and practitioners across various occupations, industries, and areas of expertise on a critical environmental topic.
