CO2 Footprint Calculator: Determine Your Individual CO2 Footprint

Compensate for your visit to the CUBITY Atelier House in Merzenich

What is the CO2 Footprint?

The CO2 footprint, also known as the carbon footprint, describes the total amount of carbon dioxide (CO2) and other greenhouse gas emissions (GHG) for which a person or organization is responsible. It defines the total amount of CO2 and other greenhouse gases emitted during the entire lifecycle of a product or service.

A CO2 footprint can also be calculated for activities, events, or products and analyzed at national, sectoral, corporate, household, or individual levels. The CO2 footprint is a clear means of identifying sources of carbon emissions and assessing progress in reducing these emissions.

Understanding how much carbon dioxide you contribute to the atmosphere through your behavior is made possible by calculating your CO2 footprint. By understanding the sources of your emissions, you can take steps to lower your emissions and make better, more environmentally friendly choices. This is crucial in the fight against climate change, as every individual effort to reduce CO2 emissions has the potential to impact the present and future of the world.


The CO2 footprint measures the greenhouse gas emissions (primarily carbon dioxide) produced by daily activities such as driving, energy consumption, and eating, and released into the atmosphere. It is important because greenhouse gases drive climate change, one of the most pressing issues of our time.

By understanding our CO2 footprint, we can recognize our impact on the environment and take steps to reduce it. This helps mitigate the effects of climate change and create a more sustainable future. It is crucial that everyone takes responsibility and contributes to environmental protection.

Help build a more sustainable future for current and future generations.

your trip to the CUBITY Atelier House and back

Understanding the CO2 calculator on our website

With our “CO2 Footprint Calculator” tool, you can estimate the CO2 emissions generated by your visit to our CUBITY Atelierhaus in Merzenich. The tool’s estimated average values for CO2 emissions in Germany are based on our assumptions derived from data from various recognized sources. Please note that these are generalizations meant to serve as guidelines only, as specific conditions may vary. It is important to keep in mind that while the tool aims to provide an indication of carbon emissions, the results may not be entirely accurate for every user. Therefore, it is recommended to use this tool for informational purposes only and to consult a specialist for a more precise calculation of your CO2 footprint.




Want to visit our CUBITY? We are happy to help you calculate your CO2 footprint for your journey.

Simply enter the travel route per transportation mode for the round trip (e.g., by taxi to the train station, then by long-distance train and public transport to the destination) into the online calculator, enter the duration of stay in hours, and the number of overnight stays, and click the green “Calculate” button.

You will then see the compensation value in euros. Give it a try.

If you wish, you can donate this amount, rounded up or down, to the suggested tree planting project.

CUBITY Atelier House
Duration of stay in hours:

the average CO2 emission per person - 0.338kg/hour

Number of overnight stays in the CUBITY Cube:

the average CO2 emission per person - 4.050kg/overnight stay

Please note that the calculations are based on the average CO2 emissions per person in Germany and may not reflect your exact carbon footprint.


The average CO2 emissions of various modes of transport are calculated based on a number of variables, including distance traveled, vehicle type, fuel type, etc. For illustration: based on information for flights from Germany, the average CO2 emissions per person per kilometer for a flight are 0.25 kg. According to data for cars in Germany, the average CO2 emissions per person and kilometer for a car are 0.2 kg. According to the same sources, the CO2 emissions of a bus and a train are 0.1 kg and 0.03 kg per person and kilometer, respectively. The average carbon dioxide (CO2) emissions per kilometer and person are 0.14 kg for an electric car, 0.023 kg for a long-distance bus, and 0.04 kg for an electric motorcycle.2

CUBITY – Energy Plus

From an energy perspective, CUBITY demonstrates that buildings can evolve from consumers to producers and thus become active urban elements with high architectural quality. CUBITY draws a holistic energy balance framework from building operation and user equipment, thereby significantly exceeding legal requirements. The renewable electricity generated on the building meets individual needs and supplies the system components for heating, ventilation, cooling, and hot water preparation.

CUBITY is not self-sufficient, but pursues a balanced annual balance of renewable generation and efficient consumption.

Offset Your CO2 Footprint with the Project “A Forest for Cologne”

To reduce your CO2 footprint and contribute to the fight against climate change, donate to climate protection projects. With your contribution, you support initiatives such as reforestation and renewable energy, which reduce carbon dioxide in the atmosphere.

The Foundation for Art and Building Culture Britta and Ulrich Findeisen recommends supporting the German Forest Protection Association in Cologne. The non-profit member association was founded in 1958 and is now a recognized nature conservation association according to the Federal Nature Conservation Act.

The goal of the association is the protection and expansion of the forest in the city of Cologne. The primary focus is to bring people closer to the forest and its biological diversity, thereby raising environmental awareness. Children and young people are particularly at the center of this commitment. For more information about the German Forest Protection Association e.V., please refer to the SDW statutes.

We appreciate your contribution to reducing your CO2 footprint! By clicking the button, you will be directed to the SDW online donation form. Via this link to the online form (PDF)
