Case Study Peru: Planning Locally, Impacting Globally – How Water and Wastewater Utilities in Peru Are Facing Climate Change

December 2018

… Peruvian wastewater utilities have begun to search practical solutions to reduce their carbon emissions, motivated by operating costs reduction, operational efficiency improvements, odor control and sludge management, thus benefiting thousands of Peruvians.

How to ensure water and sanitation services delivery under a climate change context? The climate change mitigation and adaptation plans (PMACC; Planes de Mitigación y Adaptación al Cambio Climático) are tools to address this challenge.

PMACC identify main carbon emissions sources and higher climate risks throughout the urban water cycle, along with water utilities’ opportunities to boost a positive change towards climate neutrality and adaptation. Following a standardised methodology and supported by web-based tools, the planning process becomes quicker and generates a report to inform decision makers.

This planning approach enabled some water utilities in Peru to start searching for practical carbon emissions reduction solutions, such as water utilities in Cusco and Ayacucho. The PMACC initiative was developed and implemented collaboratively between Water and Wastewater Companies for Climate Mitigation (WaCCliM) (responsible for mitigation) and PROAGUA II.

This case study is part of a series in which the water–energy–climate nexus supports the transition towards a more sustainable and low-carbon urban management.
