I have just booked my flight to the DEMA Show—the world’s largest dive show and industry event. When I made my reservation, I selected Scandinavian Airlines because they now offer travellers the option of purchasing sustainable biofuel as part of the flight ticket, so one can fly with lower CO2 emissions. I also opted to pay for a full carbon offset of my trip. It hurt my wallet, but it lifted the ache I had in my tummy. Being a transatlantic trip, it did not come cheap, but I do not see that one has a choice any longer.
