User interface

There are some major changes that have been applied to the user interface of ECAM in order to make it more user-friendly and easy-to-use:

  • Landing page: From here, you can easily “Start your assessment” to evaluate your utility’s energy performance or CO2 footprint. Further, you can activiate “Tips for new users” to include pop-ups that guide you through the tool. The new navigation bar is placed on the top and includes the pages: Home, ConfigurationInventoryResultsCompare assessments and More.


  • Configuration: ECAM provides now the possibility to manage and edit several assessments in the tool at the same time. The complete set of assessments, e.g. the evaluation of the greenhouse gas emissions of one utility for different years can then be saved in one JSON file.


  • In addition, you can load a saved JSON file to continue your assessment or you can merge different JSON files into one file by using the button “Append to current list


  • Another novelty is the function “Load assessment from Excel file“.


  1. Download ECAM input template.
  2. Fill out template file.
  3. Upload filled file.


Urban water cycle stages

  • Inventory: To evaluate your CO2 footprint or energy performance, you must insert the required input data for the systems (Water supply and Sanitation) and respective stages (AbstractionTreatmentDistributionCollectionTreatment and Onsite sanitation) that you would like to assess.


  • Fecal sludge management: Users who worked with the fecal sludge management (FSM) component in ECAM 2.2 might have realized that major changes have been applied here. Now, FSM falls under “Onsite sanitation”. The inputs almost completely remained the same.

Compare assessments

The option “Compare assessments” allows the users to compare assessments (Tutorial Video) of different time periods or different utilities. You can visualize the greenhouse gas emissions and energy consumption in different ways:

Total GHG emissions

Emissions by gas (CO2, N2O, CH4)

Emissions by stage in bar charts

Total energy consumption

Reporting function and Sankey Diagram

You can download the assessment that you are currently editing as a PDF file. You just have to click on “Results” in the navigation bar and select “Report“. This report includes all the inputs and outputs as well as diagrams of your assessment.

Use the Sankey diagram to visualize the emission flow path:

2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories

The world has committed to reducing greenhouse gas emissions to tackle climate change. IPCC’s inventory guidelines enable all countries to estimate levels and trends of greenhouse gas emissions. Even though the IPCC Guidelines were first published in 2006, they continue to provide a technically sound methodological basis for preparing national greenhouse gas inventories. The 2019 Refinement updates and supplements the 2006 IPCC Guidelines. ECAM 3.0 takes into account emission factors and other parameters that have been updated in the 2019 Refinement. Notable changes can be found in the guidance on CH4 and N2O emissions from wastewater.

Programming language

ECAM 3.0 is 100% coded in JavaScript. Original PHP language has been entirely replaced, this way the tool can run 100% in the user-side, without needing a server storing session information. This way, deploying an instance of ECAM using any web server program will work (e.g. Apache, Nginx). NodeJS is also not required.
