Aviation’s climate impact extends beyond carbon dioxide emissions. A new study from Chalmers University of Technology and the University of Gothenburg, Sweden, and Imperial College, UK, reveals that contrails can represent a significant portion of aviation’s overall climate cost. The study also shows that climate impact can be reduced by optimising flight routes.

In a new article in Nature Communications, The social costs of aviation CO₂ and contrail cirrus, the researchers demonstrate that both CO₂ emissions and contrail formation contribute materially to aviation’s climate impact – and that the associated societal costs differ substantially depending on weather patterns and routing decisions. They find that, at the global level, contrails account for about 15 percent of aviation’s climate impact when measured in economic terms.

While diversity, equity and inclusion (DEI) regulations are widely accepted in the hospitality and tourism sector, new research shows applicants may still encounter barriers to securing roles because of automated processes on job sites.   

Focusing on US recruitment sites, a new study by Flinders University researcher Associate Professor Ashokkumar Manoharan and overseas colleagues comes as a timely reminder that potential continues for employers to pay lip-service to diversity management and inclusiveness in their recruitment practices.
