atmosfair

atmosfair is a German-based non-profit climate protection organisation with focus on emission offsetting which has a fun to use CO₂ event calculator. The online-tool is available free of charge and takes into account event-related data on mobility, catering, accommodation, location and the transportation of goods.

It is most suitable for indoor events held in a single venue, based in Germany, and where the event owns all the GHGs and does not want to distinguish between stakeholder groups.

If data is missing, the calculator uses German statistical averages, so that a calculation is possible with just three basic event data.

Our Review:

If you want a quick and quite precise measurement, and are based in Germany, the atmosfair tool is terrific. atmosfair uses German emissions factors for hotel nights, public transport, and mains electricity. They are doing a considerable update over the next few months and I’ll include a review on their new features separately.

Venue: Within Venue, is entered Energy, Waste and Water. Waste is not distinguished between material type or end of life/processing.

Energy: This is done within the ‘venue’ master category. It has a complex approach to work out energy consumption estimates, which is helpful for those events with venues that won’t or can’t provide kWh. It asks building type and age, venue size, number of days used, what type of heating, and if renewable energy is used. You can also choose to input actual data (kWh). It doesn’t take into account the use of mobile power generators and the fuel these use.

Travel: The overall approach to travel measurement is to enter the percentage of people that travel by various mode of transport, plus choosing a distance category.

Accommodation: The tool asks for number of nights and people (accounting for more than one person in a room). It also includes the choice of hotel star rating.
