What are water emissions?

Water emissions refer to greenhouse gases released during water consumption, treatment, and disposal in your business operations. This includes:

  • Energy used to pump, heat, and treat water

  • Methane and other gases released during wastewater treatment

  • Emissions from chemical treatments used in water processing

Why do they matter?

These emissions matter because water processing is often an overlooked source of your carbon footprint. For SMEs, water emissions can represent 5-10% of total emissions, particularly in water-intensive industries like food service, manufacturing, or cleaning services.

If you have completed mission 1 & 2, you should be able to visit the emissions page which will allow you to add more data. Select the year you have calculated this for and enter the final figure 'Other' section on the dropdown.

What next?

Here are a few ideas on what you can do next - all of these actions can be found under projects.

  1. Set specific reduction targets (e.g., 20% reduction in water use over 2 years)

  2. Install water-efficient fixtures and equipment

  3. Implement water monitoring systems

  4. Train staff on water conservation

  5. Consider rainwater harvesting or water recycling systems

  6. Regular maintenance to prevent leaks and wastage

  7. Review cleaning processes for water efficiency
