Climate change effects of intensifying magnitude and global challenges such as sea level rise, increasing temperatures or urbanization, threaten these cities. Now, there is a need for action to achieve resilient cities. A transversal and multidimensional solution is proposed, based on the collaboration among scientists who advance knowledge, operators and basin authorities (in public and private sectors) who innovate technically and socio-politically, and local politicians who can support new, fairer and more efficient models of water governance, in constant interaction with civil society.

Greenhouse Gas Accounting tool for Chinese cities
Análisis de decisiones basadas en el riesgo climático (CRIDA) – planificación colaborativa de los recursos hídricos para un futuro incierto (Spanish)
The document compiles eleven case studies from West African region, on various themes and issues in a work that summarises the key issues of water resources management, investment, water integrity, transboundary waters cooperation and climate change adaptation.
Although the structuring of the case studies is not the same, the data collection was done according to a single template by all the editors. The cases were developed and finalised according to the data available. This has the advantage of bringing out the specifities of each case with appropriate content.
Global Protocol for Community-Scale Greenhouse Gas Inventories
Cities are the global centers of communication, commerce and culture. They are also a significant, and growing, source of energy consumption and greenhouse gas (GHG) emissions. A city’s ability to take effective action on mitigating climate change, and monitor progress, depends on having access to good quality data. Planning for climate action begins with developing a GHG inventory.
An inventory enables cities to understand the emissions contribution of different activities in the community.
Water in a changing climate: Reducing risks, leveraging opportunities and enhancing resilience
Resilience is a journey, not a destination. As the climate has changed, so too have the approaches needed to understand and proactively address associated risks and opportunities. Utilities, governments and corporations across all sectors are realizing that looking to the past is no longer sufficient to plan for our future in a changing climate.
Water Climate Discussion
The Water Climate Discussion series creates 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 recognise climate change as an
existential threat and wish to have a voice promoting a key message: water is climate. This report is based on the recorded third discussion of
the series: Energy Transitions, which was aired on Thursday, 1 July 2021. The discussion was hosted by Martin Currie and led by Ivan Vølund of VCS Denmark, John Sammon of Scottish Water Horizons and the interaction of the participants.
Powering the Wastewater Renaissance
Nearly 50% of electricity-related emissions from the global wastewater sector could be abated at negative cost by investing in readily available technologies This report investigates greenhouse gas abatement opportunities from energy efficiency in the wastewater sector.
Full-Scale Evaluation of Conventional Activated Sludge and MABR N2O emissions
Nitrous oxide (N2O) is a greenhouse gas with a global warming potential 265 times stronger than carbon dioxide on a 100-year time horizon (Eickemeier et al., 2014) and therefore, even emitted in small amounts, it can contribute significantly to global warming. In addition, nitrous
oxide is acknowledged as an important threat to the ozone layer (Ravishankara et al., 2009). N2O is an undesired bioproduct emitted during the biological nitrogen removal process in wastewater treatment systems and despite the recent efforts in understanding nitrous oxide
emissions from wastewater treatment, data from full-scale plants is still scarce.
Hydrogen 2021: A Roadmap to Net Zero
As the world recognizes the growing impacts of climate change, there is a sense of urgency to accelerate the transition to energy, transport and industrial systems with fewer greenhouse gas emissions and effectuate more sustainable modes of production
and consumption. To enable this transition, new energy carriers will be needed to transfer the increased levels of decarbonized energy
to consumers, without impacting the quality of service to residential, industrial and transportation users. Hydrogen offers
a versatile solution and is emerging as an increasingly important energy vector for decarbonized fuel sources, as well as for the storage and transport of renewable energy. Hydrogen is expected to play a critical role in decarbonizing power generation and transport, heating domestic and commercial buildings, and supporting industrial feedstock and industrial processes — including hard-to-abate sectors such as
steel, refining, cement and agriculture.
