> The reality is that a small handful of industries generate the majority of pollution You can pick your pie chart, and they'll all be a bit different based on the categories they choose. I like this one from 2016 because, even though it's 8 years old, it seems to have all the sectors: https://ourworldindata.org/ghg-emissions-by-sector https://ourworldindata.org/ghg-emissions-by-sector If you want to get to zero emissions, you have to replace or remove all of these: Iron and Steel: 7.2% Road Transport: 11.9% Aviation Transport: 1.7% Commercial Buildings: 6.6% Residential Buildings: 10.9% Cement: 3.0% Those are all small percentages. There's really no one thing you can eliminate to solve the majority of the problem. If you went by broader strokes, let's say you get rid of: ALL of Industry: 29.4% ALL of Transportation: 16.2% ALL energy for buildings: 17.5% ALL agriculture: 18.4% So at that point, we're basically back in the stone age and the various waste categories will be zero too. But then you'd have 8 billion people huddling around fire pits, which isn't zero emission either. If anyone is inclined to find another pie chart to contradict this one, make sure it's not focused on the emissions in just one tiny sector. We can say that everyone should have electric cars because ICEs are 99% of vehicle emissions, but fixing 99% of 11.9% of the total problem isn't going to solve the total problem. There isn't a silver bullet for this.
