Climate-Resilient Infrastructure Officer Handbook

Climate-related shocks and stresses are increasing in frequency and magnitude, causing damages to infrastructure systems and disruptions in the provision of services. Yet there is not sufficient investment needed to infrastructure systems’ climate resilience. The global urban infrastructure investment gap alone is estimated to be over US$4.5 trillion per year, with a premium of 9-27% is required to make infrastructure low carbon and climate- resilient Public-Private Partnerships (PPPs) are a key entry-point to mobilise private sector finance to bridge this gap and must be resilient to climate change and work to build the resilience of the communities they serve. The Climate-Resilient
Infrastructure Officer (CRIO) Handbook provides tools and guidance on how PPP practitioners can best integrate and advocate for climate-resilient infrastructure.

Evaluation of the wastewater reutilization for irrigation in high-water stress regions in Chihuahua, Mexico

This document intends to depict the existing situation in Chihuahua City, capital of the state of Chihuahua, in the northern region of Mexico, including its climate context, water situation, wastewater treatment infrastructure, and greenhouse gas emissions from this process. To achieve this goal, the methodology of this project comprises an extensive literature research on climate change, the context of Mexico, and international case studies; communication with organizations and authorities in Chihuahua that provide valuable data and information, and calculations based on literature and on the guidelines of WaCCliM.

WaCCliM – Water and Wastewater Companies for Climate Mitigation (Project Video)

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.
