> “but why not start small as well” Starting small is fine, when potential for impact is high. Otherwise it’s pointless, especially when the primary KPI is efficiency.

Unlike in construction or transportation, carbon footprint and potential efficiency gains for software are tiny. There’re are plenty reasons why iMessage and co don’t appear on the Project Drawdown list. There are much more effective leverage points that demand the attention of developers and designers. Check them out: https://drawdown.org/solutions/table-of-solutions

The best thing small interventions can do, is raising awareness. But raising awareness won’t save our planet. A developer who codes for example a parametric design tool for CNC-made houses that can be disassembled after their end of life to reduce construction waste can achieve a magnitude more than the one who optimises a website to use 700KB less data or adds artificial friction to a communication tool.
