I ventilate intensively and do not leave the windows on tilt.

Note: For the calculation of the savings, February is used as an example month.

For the example month of February this results in a saving of 0 kg CO₂e. If I ventilate intensively every day, the saving is 0 kg CO₂e per year.

If 10% of the population in Germany do this for one year, this results in a saving of 0 million tonnes of CO₂e.

This corresponds to 0 million m² of Arctic sea ice.

I lower the heating temperature in my home by 1°C.

Note: For the calculation of the savings, February is used as an example month.

Depending on the selected year of construction, 0 kg CO₂e are emitted per year. If I reduce the temperature by 1°C on every heating day throughout the year, I save 0 kg CO₂e in my home.

If 10% of the population in Germany do this for one year, this results in a saving of 0 million tonnes of CO₂e.

This corresponds to 0 million m² of Arctic sea ice.

I switch my electricity provider from conventional energy to renewable energy.

Note: When choosing, I take into account the labels recommended by the German Environment Agency and, even after switching, I still pay attention to climate-friendly use of electrical devices.

Note: The savings from this measure are calculated once per household and can therefore only be carried out once by a single person in the household.

With a conventional electricity mix, my annual electricity consumption causes the following emissions: 0 kg CO₂e. With electricity from renewable energies, my annual emissions are: 0 kg CO₂e. By switching, I save 0 kg CO₂e per year.

If 10% of the population in Germany do this for one year, this results in a saving of 0 million tonnes of CO₂e.

This corresponds to 0 million m² of Arctic sea ice.

I would like to avoid standby losses and switch off at least three electronic devices (TV, receiver, stereo system, printer, PC and monitor) when I am not using them.

Note: It is assumed that each device is in standby mode for 20 hours per day. The calculation is based on an average standby consumption of 10 W per device and switching off three of the devices listed above.

This results in a saving of 0 kg CO₂e per week.

If 10% of the population in Germany do this for one year, this results in a saving of 0 million tonnes of CO₂e.

This corresponds to 0 million m² of Arctic sea ice.

When I am at work and go to longer meetings or my lunch break, I switch off my PC and monitor.

This results in a saving of 0 kg CO₂e per week.

If 10% of the population in Germany do this for one year, this results in a saving of 0 million tonnes of CO₂e.

This corresponds to 0 million m² of Arctic sea ice.
