Southwest Airlines demonstrates above-average commitment to sustainability through fleet modernization and fuel efficiency initiatives. They show transparency in environmental reporting and have clear carbon reduction goals. However, their recycling programs could be more comprehensive, and their sustainable aviation fuel usage remains limited. While they maintain good labor practices and employee relations, there's room for improvement in their overall environmental impact reduction strategies.
