Water usage and carbon emissions
The operational carbon emissions of our built environment account for over 25% of all energy-related CO2 emissions globally. To meet the Paris Climate Agreement goals, the built environment’s energy intensity must improve by 30% by 2030.
Water-efficiency improvement is one important step in reducing CO2. We at Smartvatten help property owners, operators and users to improve water efficiency, to reduce operational CO2 emissions and to reach the sustainability goals. As the leading water efficiency expert in the building sector in Europe, we begin to provide water-related CO2 reports to all our customers on monthly basis.
How water usage generates CO2 emissions?
The majority of water-related CO2 is caused by the heating of water. Depending on the share of hot water (of total water consumption), and which heating energy type is being used, the share of these CO2 emissions can vary significantly. If we take a residential building which is connected to a district heating system, these emissions typically account for approximately 85% of total water-related CO2 emissions. Water heating by using fuels such as natural gas usually causes even more CO2 emissions. However, if geo-energy is used for water heating, it is possible to reduce the share to approximately 50%.
It is also important to take clean water production and waste-water treatment emissions into account. Typically, waste-water processing requires significantly more energy per cubic meter than clean water production. Even though a waste-water treatment plant can be energy self-sufficient, the process itself generates emissions. All relevant sources of CO2 emissions need to be included in the calculations.
Easy to use, easy to implement
With our new Smartvatten CO2 reporting tool, we can provide reports using our customer’s local water utility´s and energy company’s CO2 multipliers. We have built API integrations already to over 40 systems within the building operations and water utility sector, and we can provide the CO2 data also via API for our Key Account customers in the future.
We are ready to support our customers in making their building portfolio water-efficient and carbon neutral.
