What percentage of the limited time in your life is worth what level of impact on climate change? Do something much more likely to be useful: implement a reasonable, even revenue-neutral carbon tax and stop with this non-sense.
This is complex and will vary significantly by person. But for anyone the answer is almost certainly non-zero. Even if only marginally. And the trend seems to be increasing. The second part of your comment, seems to assume only one kind of action is possible. Others might say, great let's do both.
On its face, this argument is clearly wrong. "Absolutely nothing", is not equivalent to extremely little. Especially when, as in the case of Google Maps, there is a large multiplier.

Whereas direct action on CO2 production is incremental. We can argue it's not enough, but we cannot argue it is literally nothing.
