Many airlines offer, for a fee, to "offset" the carbon emissions produced when you fly, but such schemes are almost entirely ineffective. ████████ ███ ████ ███ ███████ ████████ ██ ████████ ████ ████████ ██████ ██████ ██████████ ██ ████ █████ █████ ████████ █████ ████ █████████ ████ ███████ ████ ███████████ ██ ██ ██████ █████████ ███ ██████████
Summary
The author concludes that airline programs that offer to offset carbon emissions in exchange for a fee are almost entirely ineffective.
Why?
The author presents an intermediate conclusion in support: the programs don’t prevent any carbon emissions.
This is supported by a premise: in most cases, any emissions-reducing projects that are funded with the money that is paid as part of the “offset” program would have proceeded even without that money.
Notable Assumptions
We know that the emissions-reducing projects toward which the airlines’ money goes would have happened even without that money. But does that prove that the airlines’ “offset” program has no effect? What if the airlines’ money can make the projects more efficient or more effective?
We want to strengthen the argument, so we’re looking for a principle that helps confirm that the airlines’ programs aren’t effective. It’s difficult to anticipate a specific principle for this question, but perhaps something like this would help:
If a project would have occurred even without airlines’ contribution toward it, then the airlines’ contribution should be considered ineffective.
