NREL research helped Joby Aviation proactively document its sustainability efforts for increased transparency, improved services, and to boost its competitive edge.
The transportation sector currently accounts for about 29% of total U.S. greenhouse gas emissions, making it one of the largest targets for lowering the carbon footprint. Further, commercial aviation causes 11% of the overall transportation sector’s greenhouse gas emissions, and its global climate impact is considered even greater because of the cumulative heat-trapping effects of contrails, nitrogen oxides, water vapor, sulfate aerosol gases, soot, and other aerosols.
Joby Aviation reported the goal for its aircraft is to help address both urban mobility needs and support the aviation industry’s transition to climate-neutral flight.as its service comes closer to launching commercially. Included are overall corporate carbon footprint accounting details, plus the results of NREL’s first comprehensive LCA of both manufacturing and operations for the eVTOL industry.
NREL also benefited, as Joby also worked with researchers to develop preliminary guidance for the eVTOL industry on conducting an eVTOL LCA study, particularly on how to define the problem, obtain the right information from engineers inside and outside their own organizations, and what areas to focus on.
Tan said the LCA for Joby helps support sustainable manufacturing practices for eVTOLs, provides a better understanding of their climate footprint, and identifies opportunities for improvement. The study also gives examples of how to make an environmental claim and how to report and present the LCA results to a wider audience.
