Further, as part of this focus we have changed our energy supplier to ‘`Bulb `__’ energy: ‘Bulb is the UK’s biggest green energy supplier. We provide all our members with 100% renewable electricity. For every unit you use, we make sure a unit is produced and put on the grid by a renewable source including solar, wind and hydro. Plus, our gas is 100% carbon neutral. 10% is green gas produced from renewable sources like food or farm waste. And we offset the rest of the gas we supply by supporting carbon reduction projects around the world.’ And so we have no CO2 footprint for energy in the house. `Water also has a cost of about 0.79 gCO2/litre `__ I’ve no clue how much we’ve used this year as we don’t have a metre. But the average water usage for a standard household in the UK is `about 164 m3 per year `__. Giving 164000 litres at 0.79 gCO2/litre = 129560 grams for 164000 litres or 0.12956 tonnes. The Plan from the 2019 Audit ------------------------------ So this means that my 2019 consumption is 4.613 tonnes of CO2. The current amount a UK citizen consumes is `6 tonnes `__ per year with a world average of 4 tonnes per year; there are big error bars on this as the variance runs from 2 tonnes to `15 tonnes `__. You can see the `history laid bare by country `__ at wikipedia. Now we can also see the `personal targets we should be aiming for `__ and that I need to be at 3.3 tonnes by 2030 and 2.3 by 2040. So the first target is lose 1.3 tonnes in 10 years but let’s try to get to this faster. For 2020 I’m going to try and do this by reducing my car travel (by half) and my food waste (to 25%). .. caution:: **COVID 19** So all plans went out the window with COVID 19 and while consumption went down it was not sustainable and so we'll need to imput 2020 and see what happens for 2021. The Plan for 2021 ----------------- Restart and follow the 2019 plan. .. note:: Version e973224ab3bcb50cae5e0e2d5f0468f700bf09a0 created on 22/12/2022 @ 15:34.
