The Water Climate Discussion series is creating a space to come together and help the water sector build its leading role in addressing the climate crisis. The series is the result of close collaboration between water institutions who have come together recognizing climate change as an existential threat and wish to have a voice promoting a key message: water is climate.
This report has been produced based on the discussion lead by Lucien Damiba from WaterAid, Trevor Bishop of WRSE, and the participants’ interaction during the first discussion of the series: Adaptation and Resilience, on Thursday, 13 May 2021. Chapter numbers refer to chapter markers in the video recording of the discussion.
The “Energy Performance and Carbon Emissions Assessment and Monitoring Tool” (ECAM) offers unique capabilities for assessing greenhouse gas (GHG) emissions and energy consumption of water and sanitation systems. Gain greater insights by identifying areas to reduce GHG emissions, increase energy savings and improve overall efficiencies to reduce costs.
Water and wastewater companies are typically energy intensive. This indicates excellent opportunities for improving energy efficiency and greatly reducing greenhouse gas emissions through more energy-efficient systems, as well as recovering energy, nutrients and other materials from wastewater.
The ‘Water and Wastewater Companies for Climate Mitigation’ (WaCCliM) project shows how the urban water sector can reduce its own greenhouse gas emissions while preparing for climate change. WaCCliM engages with the international water and climate community, with national governments and with water and wastewater utilities as well as their associations in Jordan, Mexico and Peru. Together with its national and local partners, WaCCliM is improving the carbon balance of utilities in these countries and beyond. At the same time, the project aims to ensure that utilities increase their climate resilience, reduce their operational costs, and maintain, improve and adapt their services.
Continuous and financially sustainable water and sanitation services are the backbone of resilient economies, particularly during challenging times. In addition to that, the urban water sector can lead the transition towards green recovery through targeted investments, embarking on a pathway towards decarbonization and environmental sustainability. Besides securing continuous drinking water and sanitation for hygiene measures and industrial production, an investment initiative is needed to tap the full potential of combining water, energy and climate action. Implementing low carbon energy projects in the urban water and sanitation sector improves utilities services and financial sustainability, creates green jobs and local business opportunities, protects the climate and environment and increases resilience to face future financial, health and climate crises.
This methodology outlines the path for establishing business-as-usual (BAU) emission scenarios water and wastewater utilities could exhibit in the mid-term if the current management and practices were to continue in four easy steps. The approach is created on the basis of the “Energy Performance and Carbon Emissions Assessment and Monitoring” (ECAM) tool. Based on the projected future values of key parameters, the variables that are necessary to be inputted into ECAM – the ECAM inputs – for the computation of GHG emissions can be quantified for a certain point of time. This step is facilitated by the “Tool of Projecting ECAM Inputs for GHG Emissions as BAU Scenarios (PEIGE)” in Excel format, which automatically calculates future values once users have entered the current ECAM input values and BAU trends. BAU scenarios can help to understand the impacts of adopting a low carbon policy and can serve as a technical component to inform/decide strategic planning on climate change, emissions mitigation goal setting and long-term climate policy design.
This case study analyses the greenhouse gas emissions of the water and wastewater systems of Madaba, Jordan under business-as-usual (BAU) conditions and applies the ‘Methodology to establish baseline emission scenarios’ developed by the WaCCliM project based on the Energy Performance and Carbon Emission Assessment (ECAM) tool.
This case study analyses the greenhouse gas emissions of the water and wastewater systems of San Francisco del Rincón, Mexico under business-as-usual (BAU) conditions and applies the ‘Methodology to establish baseline emission scenarios’ developed by the WaCCliM project based on the Energy Performance and Carbon Emission Assessment (ECAM) tool.
