>If we're serious about this climate crisis/change business, someone needs to cast a very hard look at google and meta for these sorts of shenanigans By all accounts client devices' energy consumption is a rounding error in terms of contribution to climate change. Going after them to solve climate change makes as much sense as plastic straw or bag bans.
It has a cumulative effect and drives the continual "upgrade" cycle. When you consider the life-time of an average mobile device, and the resources required to manufacture and ship them, it's a not insignificant problem.
>Berners-Lee writes that in 2020, there were 7.7 billion mobile phones in use, with a footprint of roughly 580 million tonnes of CO2e. This equates to approximately 1% of all global emissions
Of course, not everyone is replacing their phones yearly. Another source[2] says the average consumer phone is 3 years old. That works out to 0.33% of global emissions, assuming the phones aren't recycled/reused to developing countries. Even if assume people are upgrading their phones for app/web performance reasons, the impact is far less than 1%.
