The role of CO2 in the greenhouse effect has been fully identified by the scientific community. CO2 emissions are directly proportional to fuel consumption.
So the goal of reducing CO2 emissions merges with that of business performance, since jetfuel has always been one of airlines’ biggest cost items.
To reduce its CO2 emissions, Air France tries to cut fuel consumption by acquiring the most fuel-efficient aircraft where possible, applying a fuel saving plan, renewing its ground vehicle fleet, and optimizing its procedures.

However, demand for mobility puts limits on these efforts. The impact of higher traffic cannot be completely offset, despite substantial investments and the application of new technology solutions.
Moreover, much less is known about the impact of other aircraft emissions at high altitudes.
