This table only gives our selection of the most useful conversion factors, and CO2 equivalents are given on a Gross Calorific Value basis: Defra may eventually move to a net CV basis which will slightly increase emission factors from natural gas and LPG. They still exclude emissions associated with the production of fuels, such as oil refining or fuel distribution, so are not suitable for well to tank (WTT) or Scope 3 reporting. Figures include an estimate of radiative forcing from other aircraft emissions in the upper atmosphere, such as ozone created from NOx or condensation trails, and not just the CO2 emitted on the journey. Ignoring transport emissions, estimates by DECC in the English National Energy Efficiency Database (NEED) suggest that a typical (median) annual energy use for natural gas is around 13,260kWh and 3,380kWh for electricity. These are based on a rolling 5 year average from 2009-13 and are slightly lower than the regulator Ofgem estimates, but may reflect the trend towards much higher efficiency boilers since it became compulsory to install only condensing models. We have (from 2013 onwards) added additional types, sizes and fuels to enable a better estimate of emissions. From 2013 we have added Eurostar as a lower-carbon alternative to flying, though our kWh estimate is a bit flaky. Petrol/Diesel:  Add the number of liters of petrol/diesel you used in your car/motorcycle in a year. This is a free simple calculator designed to enable estimated carbon footprints to be calculated by most UK organisations. There is requirement to learn the entire process of manufacturing. The emission factor you have mentioned for electricity are not correct. The site that you specify does not contain any such direct information.How did you calculate? We also share information about your use of our site with analytics partners who may combine it with other information that you’ve provided to them or that they’ve collected from your use of their services. 2016 data for reporting on 2015 comparative figures) the old factors can be found in our 2016, 2015 and 2014 calculators which are also still online. Until 2015, Defra published a table of factors for 56 countries - only a few key countries where Britons have holiday homes or major manufacturing centres are included above. This typical value also excludes the distorting effect of a few very large or badly insulated homes, which increase the average (mean) value. Rail and local bus emissions vary greatly depending on time of day (how busy the bus or train is), and location - lightly used rural buses inevitably report higher emissions than ones in central London. 1Mwh=1000Kwh. Although this calculator was designed for use by small offices, it can easily be used to produce a figure for household emissions. Kindly elaborate on how did you determine the carbon emissions factor, for example... 0.85 kg CO2 per KWh and 2.653 kg CO2 per litre. The default one is recommended unless you have a good reason to use another factor: the average figure is uses the total UK electricity generation mix of coal, nuclear and gas turbines, as well as renewables. All figures, except international electricity emissions, include the incremental emissions due to other GHGs such as CH4 and N2O, so they are compatible with Scope 1 or Scope 2 emissions reporting under the GHG Protocol. We may be able to offer limited help and advice, without charge, if you send an e-mail to calculators@nef.org.uk, but this is limited by staff availability. The following schematic shows how ISO14064 help to calculate the carbon footprint of an organization, event, product, or person; Our day to day activities is moreover dependent on electricity which is mostly coming from coal-based power plants, Diesel and Petrol for our vehicles and LPG for cooking in our kitchen. The average diesel car has only slightly lower emissions due to it typically being significantly larger. I am analyzing the carbon foot print of two products.... and the other involves machinery degradation of recycled textile into fibres... i need data and the process to calculate these two processes. Presently he is working in the areas of Environmental and Renewable Energy Advisory Services. The final Carbon footprint should be in tons of CO2 (tCO2.). Source: Australian Government - Department of the Environment and Energy. Sources. Divide final value (no 5) with 1000 so that you get a total carbon footprint in a ton of CO2. Haven't you checked references given in the article? The following methodology helps you to calculate your carbon footprint resulting from the use of Electricity, Petrol, Diesel, and LPG. Previously this was based on a 5 year rolling average, to smooth out year on year changes caused by factors such as the operating performance of nuclear power stations and the latest developments in wind energy. Working Out Your CO2 Emissions From Your Electricity Bill. Note that if you charge them at home/work you will either need to deduct the electricity used for charging the vehicles from the total electricity figure, or just include the miles driven using third party charging points, such as those at motorway service areas. After taking into account the different methods of electricity generation in the UK, the average CO2 emission per kWh is 0.47 kg. We use this data to calculate our live CO2 emission intensity board . Although we allow a zero factor for onsite renewables generated, this should only be used if REGOs are not traded.
