The entire western economic system is structured in such a way that ethical consumption is difficult and expensive. While certainly I would agree that economically advantaged groups bear some responsibility to make ethical choices about what they consume, expecting someone on minimum wage to pay extra for a lower carbon product seems unreasonable (e.g. taking a train from london to paris is often significantly more expensive than flying).

Fixing the problem of climate change requires deep economic restructuring, and much of the responsibility there lies with those who have the most power to enact these changes (i.e. politicians, ceos, large shareholders). Treating climate change as an issue of individual consumer responsibility has been a long term tactic of large polluters (e.g. oil firms) to shift attention and blame from their damaging activities.
