I’m super excited to share this with you. Here is a thread on the paper. 👇👇👇 /1 The starting point is that almost all scenarios by the integrated assessment modelling community, summarized by the IPCC, assume continued economic growth even in wealthy countries, while lack of growth is assumed to hamper mitigation. #Degrowth scenarios are neglected. /2

A few days ago @MaxCRoser posted the following tweet, dismissing the aggregate material footprint (MF) as being a "horrible" indicator, which shouldn't be used to report env. impacts. Here is a thread on why I think he is wrong & the MF important. 1/9

To make his case, he refers to this paper (…ofeconomicstructures.springeropen.com/articles/10.11…) & points to a ~ equal increase in coal & decrease in clay & sand use in the EU. Thus, he says, MF is a bad indicator for env. impact, bc as an aggregate it ignores these changes & assigns equal weight to them.2/9
