<b>Notes:</b> <br> Gas consumption is generally measured in units of volume, and this is converted on gas bills into units of energy i.e. kilowatt-hours (kWh) - see Sources page. <br>
<br> To make an accurate calculation of the CO2 generated, you can enter the annual kWh used (if you know this), or you can calculate it from your bills. <br>
<br> To calculate from your bills, first select how your gas is measured. If your bills don't say what the units are, you can probably find the units on the meter. Recently installed meters measure gas in cubic metres (m<sup>3</sup>), but
older meters measure in hundreds of cubic feet - or you may have the kWh already calculated. <br>
<br> Enter the meter reading at the end of the last quarter from the latest bill and then the reading from 12 months before. <br>

<b>Notes:</b> <br> Non-farmed fish counts as organic.<br> The fertilizer used in growing food that is not organic causes greenhouse gas emissions through nitrous oxide released from the soil, and through CO2 emissions from the manufacture

<br> Meat and dairy production generates methane from animals and slurry, and CO2 from the energy used in farm operations. <br>
<br> Food transport, packaging and processing all require energy, releasing CO2. <br>
<br> Food decomposition in landfill sites releases methane. <br>
<br> Edible food can be wasted because too much is prepared, or because it has gone past its use-by date and so on. <br>
<br> Some greenhouse gas emissions are currently almost impossible to avoid: methane from tilling and soil management, and CO2 from arable farms and the operation of retail stores. These amount to around 0.2 tonnes per person. <br>

Do either a quick estimation (no bills needed) or a more accurate calculation of the CO2 and other greenhouse gas emissions that you are responsible for, as an individual, over a 12 month period. In section 1, you enter household data, so that items such as household heating and car use are shared between the members of your household. In section 2, you enter personal lifestyle and travel choices that apply to you as an individual. The calculator then gives you a chart that you can print out. Updated 2019/20 Read more. Section 1 (household) q1. How many people are there in your household? Notes: This is needed for sharing out your gas, electricity and car use between the members of your household. Enter 1 for a hall of residence. You can enter a decimal, e.g. 3.5, if you have a family member who is away from home for part of the year. more ... q2. How much electricity is used in your household? Select one option: Small house / flat (3,000 kWh) Medium (4,800 kWh) Large house (7,000 kWh) Hall of residence (2,000 kWh) Enter actual amount used from your bills Latest reading (kWh) Reading 12 months before Tick the box if your electricity comes from one of the green tariffs: Good Energy; Equipower; Green Energy Dark Green and Pale Green; LoCO2 Energy Planet, Energy Pocket+ and Energy Pocket; Ecotricity New Energy + and New Energy; Ovo Green Energy and New Energy kWh tonnes CO2 Notes: Electricity use is measured in kilowatt-hours (abbreviated to kWh). To make an accurate calculation, you need to find your latest bill and the reading (in kWh) at the end of the last quarter. Then find the bill 12 months before it and the corresponding reading. The CO2 emission factor for electricity is taken to be 0.309 kg / kWh [read more] There is a reduction of 25% in CO2 emissions for the green tariffs listed [read more] q3. How much gas is used in your household? Select one option: Small house / flat (12,000 kWh) Medium (18,000 kWh) Large house (27,000 kWh) Hall of residence (5,000 kWh) Enter actual kWh used Amount (kWh) Calculate amount used from your bills Select how your gas is measured: Cubic metres (newer meters) 100's of cubic feet (older meters) Latest meter reading Reading 12 months before Difference kWh used kWh tonnes CO2 Notes: Gas consumption is generally measured in units of volume, and this is converted on gas bills into units of energy i.e. kilowatt-hours (kWh) - see Sources page. To make an accurate calculation of the CO2 generated, you can enter the annual kWh used (if you know this), or you can calculate it from your bills. To calculate from your bills, first select how your gas is measured. If your bills don't say what the units are, you can probably find the units on the meter. Recently installed meters measure gas in cubic metres (m3), but older meters measure in hundreds of cubic feet - or you may have the kWh already calculated. Enter the meter reading at the end of the last quarter from the latest bill and then the reading from 12 months before. The CO2 factor for natural gas is 0.203 kg / kWh ...[more] q4. Is heating oil, coal, wood or bottled gas used in your household? No Yes Enter your use over the last year: The number of litres of heating oil: The number of kilograms of coal: The number of kilograms of wood: The number of kilograms of bottled gas: Then select 'Calculate' tonnes CO2 Notes: The following CO2 factors are used.

Above-average meat/dairy Average meat/dairy Below-average meat/dairy Lacto-vegetarian Vegan tonnes CO2 FOOD MILES: How much of your food is produced locally? Very little (much foreign / out of season food) Average Above average Almost all tonnes CO2 FOOD PACKAGING AND PROCESSING: How much of your food is packaged / processed (e.g. 'ready meals', tins)? Above average Average Below average Very little tonnes CO2 COMPOSTING: How much do you compost potato peelings, leftover and unused food etc? None Some All tonnes CO2 WASTE: How much food do you waste (on average, over one fifth of edible food is thrown away)? Above average (50% more) Average Below average (50% less) Very little (90% less) FOOD TOTAL including almost unavoidable 0.2 tonnes tonnes CO2 Notes: Non-farmed fish counts as organic. The fertilizer used in growing food that is not organic causes greenhouse gas emissions through nitrous oxide released from the soil, and through CO2 emissions from the manufacture and transport of fertilizer. Meat and dairy production generates methane from animals and slurry, and CO2 from the energy used in farm operations. Food transport, packaging and processing all require energy, releasing CO2. Food decomposition in landfill sites releases methane. Edible food can be wasted because too much is prepared, or because it has gone past its use-by date and so on. Some greenhouse gas emissions are currently almost impossible to avoid: methane from tilling and soil management, and CO2 from arable farms and the operation of retail stores. These amount to around 0.2 tonnes per person. ...[more] q7. Health, education, etc : tonnes CO2 Notes: Carbon dioxide is generated by the health service, schools, social services, the armed forces and so on . This amounts to 1.1 tonnes per person per year for the UK. You have no direct control over this amount, which is generated on your behalf, but you can join campaigns to make public services more energy efficient, especially if you work within one of them. q8. Journeys by bus Enter the number of miles travelled in the last year (or leave blank) and select 'Calculate': Enter your regular mileage each week: Enter your regular mileage each month: Enter your other mileage in the year: miles tonnes CO2 Notes: You can estimate your mileage by: - estimate the average journey time - multiply by average bus speeds (roughly 15mph for urban journeys and 20mph for rural journeys). If you are a regular bus traveller, enter a typical week and/or month and these will be multiplied up (by 48 and 12 respectively) and added to your other mileage. The CO2 emission factor for bus travel is taken to be 100 g/mile ...[more] q9.

Then the hours spent on flights within the UK, or in flights between airports outside the UK. For example, if you went on one return trip with two friends to Spain, enter a "1" in the Spain box. The calculator assumes emissions of ¼ tonne CO2 equivalent per hour flying (roughly 500 g per mile)...[more] q11. Miscellaneous personal lifestyle choices: What is your miscellaneous spending? Above-average (5 tonnes CO2) Average (3.4 tonnes CO2) Below-average (2.4 tonnes CO2) Much below-average (1.4 tonnes CO2) Do you recycle paper, glass and metal? No Yes Do you recycle plastic apart from bags? No Yes tonnes CO2 Notes: Your miscellaneous spending is all your other spending i.e. on: - recreation and leisure facilities - housing - household appliances - hygiene - hotels and other holidays - furnishings - clothing & footwear - alcohol & tobacco - post and telecommunications - books, newspapers & magazines and so on. Almost all of this spending will be associated with greenhouse gas emissions to some degree. Spending on these tends to follow size of income. Your total tonnes CO2 What to do now: - Compare your total with the world and national averages in the graph below - View/print summary graph: - Set a target to reduce your total for the coming 12 months - we have found that a 10% reduction year on year is easily achievable. Read more... How your total compares to the rest of the world Your total World average 4.4 UK average* 14.1 USA 17.6 China 6.2 India 1.8 Mozambique 0.3 For sources, see carbonindependent.org/94.html *The figure for the UK includes adjustments for greenhouse gases other than CO2. The figures for the other countries do not, as these are not so readily available. Notes The calculator is based around a family household unit, where car travel is done to bring in income for the family or to travel for family leisure, and so CO2 emissions need to be shared between all members of the household. If your circumstances are different, you may need to adapt the calculator, e.g. enter the household size as 1, and share out household electricity and gas before entering it. Some travel may be carried out as part of your job e.g. international aid workers may have to fly in order to do their jobs effectively. Enter in the calculator just what you choose to do, not what you cannot avoid. Last updated: 7 Mar 2020
