The basis for answering this question is the account of internationally binding legal targets in environmentalism, such as the 1.5 degree Celsius limit for global warming. Given this target, it is clearly necessary not to rely only on technological strategies but also on behavioral strategies. Consuming less, not only consuming smarter.
And this will probably take us to an overall situation of post-growth or degrowth, which poses serious challenges in terms of pension schemes, labour markets, etc.
It will be necessary to develop solutions for that because just forgetting about the environmental targets is clearly no option. Because this would take us to severe consequences of climate change, biodiversity loss, disturbed hydrogen cycles, etc.
