The connection between climate change and water has traditionally focused on the inevitable impacts: droughts, inland flooding, sea-level rise. Increasingly, however, we’re also discussing the role that the water sector can play in mitigating the crisis, and as cq9�ټ��� Global Water Director, it’s a topic that I’ve had a renewed focus on in recent weeks.

On Earth Day last month we launched our updated Climate Action Plan at cq9�ټ��� which sets out a series of bold climate commitments, including achieving net-zero greenhouse gas emissions across our value chain by 2040, and maintaining carbon neutrality status and 100% low-carbon electricity for our operations.

The fact that we are the first consultancy organization to have had these commitments approved by the (SBTi) demonstrates our industry-leading position in the battle against climate change, and I’m committed to furthering that leadership role in the water sector.

I’m already incredibly proud of the work we have undertaken to support our water sector clients with their journey to net-zero and I’m delighted that these efforts are being recognized at this year’s . cq9�ټ��� has been shortlisted in the Net Zero Carbon Champion category, which recognizes companies whose products and services have done the most to reduce the carbon emissions of their customers.

The total carbon footprint of the global water sector has yet to be accurately calculated, although suggests that the sector’s energy usage alone accounts for 1.2% of global emissions. Add in other sources such as methane and nitrous oxide emissions at wastewater treatment plants, and the sector’s contribution

At cq9�ټ���, we’ve shown that significant reductions in these emissions can be realized through technology and innovation, from the adoption of energy-efficient treatment processes to renewable energy generation using biogas. Here are some examples:

• We were to design new greasy waste and food waste treatment facilities to maximize electricity generation at the Changi Water Reclamation Plant  and reduce the facility’s carbon footprint.
• We partnered with VCS Denmark to achieve carbon neutrality and energy independence at its Ejby Mølle WRRF. The plant now generates more than 150% of its energy demand by adopting sidestream and mainstream assisted deammonification capabilities.
• We that produces all the power necessary to meet the daily average demands of the San José-Santa Clara Regional Wastewater Facility in the City of San José, California.
• We partnered with Yarra Valley Water, Australia to explore sustainable hydrogen production at its Aurora wastewater treatment plant.
• cq9�ټ��� is working with the U.K. government to develop a saltmarsh code that will contribute to net-zero ambitions by sequestering “blue carbon” in coastal wetlands.
• We established our program to support our clients, recognizing that there are many different strategies and approaches to achieve net-zero outcomes.

In addition to supporting our clients, we’re also working closely with our global network of technology partners and suppliers to reduce carbon emissions. I’ll be joining at the in Madrid on May 18, titled Leading the Race to Zero, which will explore how we can reduce the carbon footprint of the water industry’s supply chain.

As a trusted partner to our utility clients, it's our responsibility at cq9�ټ��� to identify technologies and solutions that align with their net zero commitments – and to encourage our peers in the supply chain to adopt similar practices. As part of our new Climate Action Plan, we’ve committed that 65% of our suppliers by spend (covering purchased goods and services) will have science-based targets by 2025.

The good news is that collaboration around water’s journey to net-zero is already happening. cq9�ټ��� is proud to support the US Water Alliance’s call to action, the first sector-wide commitment to achieve net-zero in the U.S. water sector by 2050. I was honored to join a team of over 35 water sector stakeholders to help formulate this collaborative vision, which also enshrines a One Water approach as an urgent priority. Similarly, the U.K. water sector has developed its own .   

While those of us who work in the water sector will understandably be directing much of our efforts towards droughts, floods and other climate change impacts in the years to come, our potential contribution to the reduction of carbon emissions should not be overlooked. By collaborating with our utility partners and other industry stakeholders, I am confident that we can significantly reduce the water sector’s carbon footprint and I look forward to discussing these strategies at the Global Water Summit this month.
