The footprint calculator quantifies the relevant greenhouse gas emissions of a typical inhabitant of Germany, Austria or Switzerland and generates their carbon footprint. The calculated greenhouse gas emissions are based on current emission factors, scientific publications and international and national statistics.
The aim is to provide users with a simple application, through which they can input a few details to specify their greenhouse gas emissions and thus obtain a calculated result to raise their own level of awareness. They can also make a corresponding climate protection contribution for the emissions calculated, which is used to finance myclimate climate protection projects.
The calculator includes all relevant activities in the areas of mobility, food, culture, consumption and housing, as well as an automatically accruing share of public emissions. The set of questions has been kept as simple as possible and so can only give an approximation of an individual’s effective footprint. For a more comprehensive footprint with respect to housing please use the myclimate household calculator, for your mobility use the myclimate flight calculator and the car calculator, and for any cruises use the cruise calculator. You will find these here: CO2.myclimate.org
To offer a more complete perspective, in the current version myclimate includes a share of emissions for public services, alongside areas such as mobility and housing that individuals can influence personally. Such emissions cover infrastructure regularly used by all inhabitants of a country, be it administrative facilities, hospitals, swimming pools or roads.
The carbon footprint covers relevant consumption associated with a person’s lifestyle in their everyday life, leisure time and at home. All emissions are considered across their entire lifecycle and reported per year. The data forming the basis for personal CO2 footprint calculations comes from the ecoinvent 3.6 database and additional specific sources and statistics in the areas of mobility, food, consumption, leisure and culture, as well as housing. The IPCC (Intergovernmental Panel on Climate Change) 2013 method is used as the assessment method. This method uses greenhouse gas potential over a 100-year time horizon (GWP 100a). The climate impact is generally indicated with the unit “kg CO2e”, i.e. “kilograms of CO2 equivalents”, which adds up the effects of all relevant greenhouse gases. The most common greenhouse gas is carbon dioxide (CO2), which is produced when fossil fuels are burned, for instance. Besides CO2, other greenhouse gases such as methane (CH4) and nitrous oxide (N2O) are emitted in numerous processes.
myclimate aims to map the resulting greenhouse gas emissions as completely as possible. Within the scope of the system boundary are both areas of life that can be influenced directly as well as public emissions. With the areas of transport, flights, food, consumption, leisure and culture, as well as housing, all relevant sources of emissions are covered. The footprint is reported per person and year.
A user’s greenhouse gas emissions are ascertained using specific statements (multiple choice) that describe individual lifestyles in the broadest sense. Such statements are linked to consumption figures that are based on statistics, values taken from literature and user behaviours.
The individual areas are explained briefly in the following section.
Means of transport: This area includes four statements that cover the bandwidth from relatively environmentally friendly behaviour to CO2-intensive behaviour. Shares of individual mobility, the use of public transport and travel by bike/on foot are ascribed to the statements accordingly. The data behind this comes from the Swiss microcensus.
Flying: Journeys by plane in a private capacity are of relevance here. Answers range from “I never fly in a private capacity” to “I fly to long haul two to three times a year”. The values forming the basis for this come from the updated myclimate flight calculator.
Food: The subject of the food section are different eating habits, ranging from “vegan” to “I eat meat in almost every meal”.
Consumption, leisure, culture: This is probably the most underestimated area of life. Questions revolve around the purchasing of clothes, devices and furniture, expressed with an average outlay in euros per month, linked with the CO2 emissions for a typical shopping basket. In addition, recreational behaviour and activities in connection with personal healthcare are associated with relatively high greenhouse gas emissions.
Housing: CO2 emissions in the housing and energy field are essentially based on three criteria: the amount of living space per person, the construction standard of the flat or house (older structure versus renovated, energy-efficient house) as well as the heating system in use (based on fossil or renewable energy sources).
Public emissions/services: These emissions for state infrastructure are a new component of the calculation and accrue automatically for every inhabitant. The flat-rate value per person is based on statistics and values taken from literature. It is reported in t CO2 per person and year.
All activity and consumption data is linked to background data, which means greenhouse gas emissions are calculated using current emission factors. The database used is the ecoinvent 3.6 platform, the world’s largest internationally recognised database for eco-inventories, as well as scientific publications, internal empirically established values and publicly available statistics. The geographical focus of the factors is Europe, with an emphasis on Germany, Austria and Switzerland. As the footprint calculator is designed to be user friendly and has been kept simple, the results only offer an approximate representation of reality, and individual results could deviate substantially. For this reason, a safety margin of 10 per cent has been added to the results.
