I’d like to know how much CO2<\/sub> I’m putting into the atmosphere from my commute.<\/p>\n\n\n\n I recall that I fill up about twice a month, and the petrol tank usually takes about 40 litres each time. I could work out the MPG, but this is a quick estimate. It’ll do for now.<\/p>\n\n\n\n Burning Petrol releases about 2.31 kg per litre (according to Therefore, in a month, 2 tank-fulls, or 80 litres burns into…<\/p>\n\n\n\n 80 \u00d7 2.31 = 184.8 kg of CO2<\/sub> <\/p>\n\n\n\n Taking holidays into account, let’s assume I do that commute for 11 months of the year, which means my commute looks like<\/p>\n\n\n\n 184.8 \u00d7 11 = 2032.8 kg, or just over 2 tonnes of CO2<\/sub> <\/p>\n\n\n\n There we go. 2 tonnes. The next challenge is to try to reduce it.<\/p>\n\n\n\n According to this article at The Guardian<\/a>, manufacturing a small to medium sized car might produce 6-17 tonnes of CO2<\/sub>, which I need to factor in when deciding whether to replace the car<\/p>\n\n\n\n Note<\/strong>: My internet-based research said a car probably emits 4.6 tonnes, according to https:\/\/www.epa.gov\/greenvehicles\/greenhouse-gas-emissions-typical-passenger-vehicle<\/a>.
