Was just thinking about how big a pile of carbon would I need to offset my CO\u2082 contributions while on the walk.<\/p>\n<p>Ideally, the CO\u2082 contributions should be put back underground, so the first idea would be to just cut down bury some trees (after all, once grown, trees aren&#8217;t being much of a net CO\u2082 scrub) &#8211; but that would be wrong. Charcoal \u2014 being pure carbon and much more stable than biomass \u2014 would be much better. Sure, you&#8217;ve got to turn wood into charcoal before you do anything with it, but the process of turning wood into charcoal doesn&#8217;t produce additional CO\u2082. This means: charcoal is the way to go.<\/p>\n<p>Now that we know our preferred form of carbon, let&#8217;s take a look at the numbers:<\/p>\n<ul>\n<li>\u00a0EU&#8217;s CO2 emissions are ~6.4 tons per year per capita. USA is 16.5. (using data for 2014).<\/li>\n<li>Carbon represents 27.3% of CO2 by weight.<\/li>\n<li>Density-wise, charcoal clocks between .2 and .6 tons per m3.<\/li>\n<\/ul>\n<p>If you wanted to sequester the amount of carbon &#8220;you&#8221; are responsible for, the pile of carbon you&#8217;d have to manage would weigh ~1.75 metric tons (4.5 metric tons if you&#8217;re in USA). This translates to a nice 2.9 &#8211; 8.7 m\u00b3 (7.5 &#8211; 22 m\u00b3 for USA\/NA in general) pile of charcoal to bury somewhere at the end of every year.<\/p>\n<p>This, of course, excludes emissions related to cutting down trees, reforestation (!) and transportation; we also assume that charcoal production is using excess power from the wind farms on days when there&#8217;s too much wind. The good news, though, is this: most of the per-capita emissions is produced by companies. If you only wanted to deal with the emissions that you cause directly, the pile would probably be much smaller.<\/p>\n<p>Emissions per capita stuff stolen from <a href=\"https:\/\/data.worldbank.org\/indicator\/en.atm.co2e.pc\">here<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This might lean ever so slightly in the politics territory, but here&#8217;s a fun calculation.
