That equates to an additional 200t of CO2 per year per aircraft. Some airbus operators have hundreds of aircraft in their fleet, so it is not hard to see the major difference small SOP changes can make to cost and environmental impact.
Thanks. I've only ever done packs off takeoffs at one airline, and it was quite miserable, as it was inevitably needed in the summer. How quickly does the 320 cabin get uncomfortable with packs off?
