Given the financial risks associated with ICAO's commitments for carbon neutral growth of the industry, and potential impact of current and future national/supranational emissions trading and carbon tax policies over the expected lifetime of a plane that's not going into service for a few more years yet, perhaps it's quite relevant even from a business-focused perspective.

Simplistic counter-argument: At this point, any article needs to mention the environment if we're going to cut back on carbon pollution as much as we need to.

Nope. You can increase carbon pollution in one area while still reducing total net carbon emissions.

You can also give food to every hungry child on earth.
