Domestic computer use simply isn't a big fraction of a person's total energy consumption:
e.g. this study[1] in the UK puts "IT" as <6% of household electricity use, which is itself a fraction of a person's total energy use.
edit: and this[2] indicates that datacenter usage is also not very significant.
Therefore, no amount of optimising web pages will make a meaningful difference to carbon output.
As web professionals, it's better if we direct our focus towards more productive areas around this goal -- by e.g. donating to relevant campaign groups, or using our tech skills to produce media on the topic.
