When Aviation CSR Efforts Are Not Enough: How Do We Inspire Airline Passengers to Offset Their Travel Footprints?

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Voluntary carbon offsetting programs (VCOPs) are available for airline passengers who want to take action and offset their scope 3 emissions. Yet, their uptake is very limited. In this study, we propose an integrated theoretical model involving the norm activation theory and protection motivation theory to understand airline passengers ...

Iron‐Catalyzed Hydrodecarboxylation of Fatty Acids From Vegetable Oils for Drop‐In Biofuel Production

European Journal of Organic Chemistry, EarlyView.
An iron‐catalyzed hydrodecarboxylation for renewable hydrocarbon production is reported, featuring an alternative hydrogen source and a commercially available iron salt as the catalyst. The protocol enabled efficient one‐pot Cn–1 hydrocarbon synthesis from vegetable oils under mild and open‐air conditions.
