At least in the EU the "no one cares" is changing. Member states need to have legislation in place that means from 2020 all new builds are "nearly carbon zero" (unfortunately left to interpretation by country). In my country that means homes have insulation and heating requirements on par with Passive House standards, as well as the majority of their energy coming from renewable sources.
