Water and Wastewater Companies for Climate Mitigation (WaCCliM) in Mexico

In Mexico, water utilities have a difficult task meeting user’s demands. Low tariffs, high water consumption, and a complicated legal framework have led to unsustainable water abstraction, high energy costs, high water losses, and inadequate wastewater treatment, which contribute to very high greenhouse gas (GHG) emissions. Climate change will only exacerbate current conditions. During the Paris COP21 negotiations, Mexico was seen as a leader. It has ambitiously committed to reduce 22% of its GHG emissions by 2030 compared to baseline scenario, with the potential to raise the target up to 40%, and 50% by 2050 compared to the year 2000.

The Water and Wastewater Companies for Climate Mitigation (WaCCliM) project is demonstrating that the water sector can reduce greenhouse gas emissions: in the short-term by improving operational efficiency and adopting energy efficiency measures; in the long-term by proactively upgrading and reforming their drinking water and wastewater systems. Water utilities working with WaCCliM are becoming sector leaders, and are seizing the opportunity to become more efficient and effective in an uncertain future.
