The climate is heavily burdened by the high energy consumption of households and the heating of houses and apartments. In principle, a smaller living space causes less CO2 emissions. But even without moving, there are some simple changes you can make to improve your carbon footprint.
Big power guzzlers are domestic appliances, such as the refrigerator – after all, it runs day and night. To reduce energy consumption here, it pays off buying only appliances with the highest efficiency class A+++.
You can also make a big difference in heating: With every degree that is heated less, you can save on average 6% CO2 emissions. The use of a programmable and smart thermostat can be very helpful for this. Moreover, heating with heat pumps saves a lot of energy – as well as costs – in the long term.
Another important factor is the choice of electricity supplier. Green electricity providers support e.g. the expansion of wind power or solar energy systems. By purchasing eco-certified electricity, you can thus reduce your CO2 emissions in a very targeted manner.
In addition, make sure you have good sealing and insulation, in order to keep the room temperature stable. Problem areas in this respect are often windows and doors where heat can escape.
But even small changes have their effect: replacing classic light bulbs with LEDs can, for example, save about 135 kilograms of greenhouse gas emissions per year in a single-family home. You can also make sure that devices such as PCs, laptops and televisions do not continue to run in standby mode when not in use, but are actually switched off.
