Interesting so land area of world / 8000 gives 1 Glensanda per 18600km2. Area of UK is 242000km2 so we would need about 13 Glensanda sizes quarries in the UK. Of course it would be fairer if were weighted by amount of harm done to the climate per country, so we should have more per km2 than an undeveloped country, but even so doesn't seem like that large an impact.
- nkoren 7y agoI don't think land area is the metric to use here. Quaries need to be located close to the coast, in order to minimise shipping costs. There's a lot of land in the interior of continents which would not be suitable for this kind of operation. So probably a better metric is total length of coastline. The UK has 12,429km of coastline, out of a world total of 356,000. So that would imply 279 Glensanda-sized quaries in the UK. Good news for the UK (and bad news for everyone else): weighting by amount of harm done to the climate wouldn't work. In addition to being located near coastlines, the quarries need to be located in tropical and subtropical regions. So in fact there wouldn't be any quarries in the UK. Looking at this source: http://chartsbin.com/view/ofv http://chartsbin.com/view/ofv, it appears that there's about 275,000km of suitable coastline. The top 3 countries would be: Indonesia (1,592 Glessandas), Phillipines (1,056 Glessandas), and Australia (749 Glessandas). I'm not sure whether or not that's feasible. But at a smaller scale, as a partial solution to sequestration, it seems within reach.
