Our consumer behavior has a significant impact on the climate, and we can also reduce our carbon footprint by making smart choices when selecting bathroom fittings.

All consumption decisions cause CO2 - let's make good ones!

Every kilowatt hour of energy we consume has an impact on our carbon footprint. Every KWh not consumed is our valuable contribution to climate protection.

Many consumers now understand that every purchase they make contributes a certain amount to their personal carbon footprint. Whether it's consuming mangoes flown in from Asia or locally grown carrots, or whether we choose a long-distance flight or a train ride to London, our actions impact the climate to varying degrees. Even the choices we make when furnishing our homes matter. From the screed to the washbasin and hand shower, all the way to the ceiling lamp: the CO2 analysis* commissioned by Hansgrohe reveals the effects on your CO2 footprint in the bathroom and the extent of these effects in a detailed and striking manner, highlighting where the most significant greenhouse gas emissions occur.

* The scientific analysis is the result of a thesis written by Timo Armbruster (M. Sc.) for hansgrohe in 2022 at the Faculty of Business and Law at Pforzheim University.

What Hansgrohe's CO2 analysis takes a close look at

The most important result of the hansgrohe bathroom analysis: with clever product selection, you can significantly reduce the CO2e footprint of your bathroom use.

The scientific background: All products or buildings (or parts of buildings) cause a lot of energy consumption over their entire life cycle emissions. Six different gases are summarized as "greenhouse gases" that contribute negatively to climate change, the best known of which is Carbon dioxide (CO2). The effect of these gases is measured and compared in CO2 equivalents (CO2e). What basic assumptions were made in the aforementioned CO2 analysis for the bath?

  • represents a standard-sized room as it might be in demand today
  • is ten square meters in size and part of a residential building in Freiburg, Germany
  • is occupied by four people
  • has a life span of 20 years

For the CO2 footprint of the bathroom, the hansgrohe analysis uses the The construction and disposal phases of the components are considered as well as scenarios for the utilization phase

Construction phase? Utilization phase?

How many kilograms of CO2e are emitted when my ceramic tiles are produced and transported? How much CO2e is emitted during the production of my wooden basin taps? These are questions that determine the greenhouse gas emissions in the Production phase concern.

How many kilograms of CO2e does our family consume when showering and washing our hands? Can we still save hot water in the bath tub or even reduce toilet paper consumption? Such questions concern the CO2 footprint during the use of the bathroom products and fittings. The most important result of the hansgrohe bathroom analysis is already clear:You can save the most CO2e here – with a clever choice of product. 

So much climate protection potential in the bathroom

What are the five top results of the CO2e bath analysis?

  • Your CO2e footprint in the shower: You can save money by making sustainable purchasing decisions for showers, tiles, thermostatic mixers, shower hoses, floor coverings and shower enclosures. Your biggest savings potential lies in the shower! You can achieve a huge effect when you buy energy-saving showers.
  • Your CO2e balance at the WC area can be improved by making sustainable purchasing decisions for the toilet, toilet bowl system, toilet brush holder or roll holder. Interestingly, there is great potential for savings in the consumption of toilet paper.
     
  • Your CO2e footprint at the washing station can be reduced by making sustainable purchasing decisions for washbasins, vanity units, basin taps, mirrors, soap dispensers and towel racks. You can save an enormous amount of hot water energy with reduced-flow taps.
     
  • Your CO2e balance in the bath tub can be improved by making sustainable purchasing decisions regarding the material of the bath tub, wall covering and tiles, bath mixer, hand shower or shower hose    
     
  • Climate-related emissions from floors and ceilingscan be reduced by making sustainable purchasing decisions for screed, flooring, ceiling cladding, ceiling spots or plaster. You can save many tons of CO2e in the long term with energy-efficient underfloor heating and the right heat insulation.

 

How to plan and use your bathroom sustainably

The good news is that you can do a lot for the climate when using and furnishing your bathroom.

How do you actually reduce the CO2 footprint of your bathroom?

What is the conclusion of the CO2 analysis in the bathroom?

The CO2 bath analysis from hansgrohe shows one thing clearly: consumers have the greatest leverage to reduce greenhouse gases during the use phase. With EcoSmart technology, you can save valuable resources while using your taps and showers. It's best to do a little more research before deciding on a bathroom product. Look out for terms such as "water-saving", "flow-limited", "EcoSmart" or "energy-efficient". Because what you think through before you buy will protect your ecological footprint for many years to come. The potential for CO2 savings is therefore also becoming increasingly important in the production of bathroom furnishings. For many products that you install and furnish in the bathroom, you will find an environmentally friendly and lower-consumption variant in the trade. It all depends on the carbon footprint of a product. So look out for international environmental and sustainability certificates such as theForest Stewardship Council® or the Cradle to Cradle Certified®. You can read about what these certificates stand for in our magazine article on sustainability certificates and environmental certificates;

Frequently asked questions about saving CO2 in the bathroom

What is the CO2 footprint in the bathroom?

The CO2 footprint in the bathroom refers to the amount of carbon dioxide emissions caused by activities and products associated with bathroom furnishings and bathroom use. In addition to the building materials for the entire interior, this includes water consumption, water heating, the use of electrical appliances and the production and disposal of hygiene products.

Can I save CO2 when renovating my bathroom?

Yes, there are many ways to reduce greenhouse gases in the bathroom and create an environmentally friendly home. By using a water-saving shower system consisting of a shower head and hand shower and adapting your showering habits, you can save a considerable amount of CO2.

What makes hansgrohe toilets and washbasins climate-friendly?

hansgrohe toilets and wash basins are made of high-quality sanitary ceramic, which has a long service life and is always climate-friendly. In addition, hansgrohe taps at the wash basin impress with resource-saving functions such as EcoSmart and CoolStart

Do hansgrohe taps reduce the emission of harmful greenhouse gases?

Yes. hansgrohe taps on wash basins and bidets require only 5 liters of water per minute at 3 bar as standard (EcoSmart+ products even consume only 4 l/min). The less hot water that needs to be treated, the less CO2 is emitted. This also has a noticeable effect on the energy bill;

Do I produce fewer greenhouse gases with hansgrohe showers?

Yes! hansgrohe showers with EcoSmart use up to 60 percent less water than those without this energy-saving technology. Less hot water = lower energy consumption = lower CO2 emissions. This is also good for your wallet;
