Water positive can be defined as the concept where an entity, such as a company, community, or individual, goes beyond simply conserving water and actively contributes to the sustainable management and restoration of water resources. This involves implementing practices and technologies that reduce water consumption, improve water quality, and enhance water availability. The goal of being water positive is to leave a positive impact on water ecosystems and ensure that more water is conserved and restored than is used or depleted.[1][2][3]

History
The "water positive" concept took root in the construction industry in the early 2000s. This was in response to an agenda for optimizing construction practices by reducing their environmental impact through land and material reductions, as well as energy and water conservation, to produce "zero impact buildings."[4] To conserve water, rain harvesting was considered to minimize dependence on freshwater consumption.
The water positive concept expanded to other domains and industries as concerns began to rise over the challenges of global freshwater scarcity. The idea gained momentum because it could be conveniently coupled with the previous agenda of "Net zero emissions," sharing a common goal of healing the environment through sustainable management of vital resources. Civil and corporate responsibilities aim to control resource consumption and manage waste to achieve a net positive impact. To achieve these goals, compensational incentives are introduced as credits (carbon credits or water-positive credits) that can be commercially exchanged for legal tender between the seller (authorized carbon credit or water-positive holders) and buyers, promoting positive environmental impacts.
Like the compensation of Greenhouse gases (GHG), the idea behind water positive is to balance the water footprint by implementing process efficiency measures, water purification, aquifer recharge, ecosystem conservation, and other water compensation projects. It focuses on managing this critical resource so that organizations contribute more to global water sustainability.
Water impact assessment
The Water Positive Initiative seeks to assess the environmental impact of water consumption across various industrial domains. This cannot be achieved by looking at an entity's direct or indirect water consumption without considering the product or service exchanged locally, regionally, or internationally. These commodities or services have a hidden water consumption value that is often overlooked. In the 1990s, Prof. John Anthony Allan, a British geographer and expert in water resources and environmental management, introduced the concept of Virtual Water (VW), which implies that the exchange of goods and services has a tangible water exchange value associated with them and must be considered.
Water positive and Virtual Water combine to provide a better impact assessment of direct, indirect, and virtual water usage, relating commodities to their virtual water footprints.
Expansion of the Concept
Global expansion of the water positive concept emerged in the 2000s, driven by the United Nations Millennium Development Goals relating to access to drinking water and the need for industries to participate in water sustainability in their production.
Beverage companies like The Coca-Cola Company and PepsiCo were pioneers in establishing water positivity commitments for water-stressed regions by investing in water efficiency and community projects. They set ambitious goals to reduce potable water used per liter of product production, becoming models for other industries. In June 2007, Coca-Cola announced a multi-year partnership with World Wildlife Fund(WWF) on water conservation. E. Neville Isdell, Coca-Cola's chairman and CEO, stated: "Our goal is to replace every drop of water we use in our beverages and their production. For us, that means reducing the amount of water used...recycling water used for manufacturing processes so it can be safely returned to the environment, and replenishing water in communities and nature through locally relevant projects."[5]
With the UN Sustainable Development Goals established in 2015 and growing social pressure for companies to adopt environmentally sustainable practices, more companies across various industries publicly committed to the goal of being water positive by 2030 to 2050.
The surge in commitment to this initiative occurred after 2015, when leading companies such as Microsoft, Google, Ecolab, Unilever, Nestlé, AB InBev, Levi's, IKEA, Cargill, BP, Gap Inc., Colgate-Palmolive, Meta, Diageo, Starbucks, Danone, IBM, Procter & Gamble, Intel and Mars proposed drastic reductions in their operational water consumption and offsetting consumption by implementing strategies such as rainwater harvesting systems, water purification, reforestation projects, and aquifer recharge, among other initiatives, focusing on improving water-stressed basins.[6]
The water positive concept has also made its way into the world of sports. On August 7, 2023, Canada Ocean Racing, an offshore Sailing Team (competing in the IMOCA Globe Series), unveiled its new team: "Be Water Positive".[7] The team partnered with the renowned sailing team Alex Thomson Racing, which managed British solo sailor Alex Thomson’s five Vendée Globe campaigns over the past[when?] 20 years. Canada Ocean Racing's goal was to be the first Canadian team to complete the Vendée Globe and build awareness of what “Water Positivity” means.[8] By forging alliances with key organizations in the water reuse and desalination industries and supporting the UN Water Action Decade, the race team aims to educate and engage the public on the importance of responsible water management.
Definition
Being "water positive" means an entity, such as a company, community or individual, going beyond simple water conservation and actively contributing to the sustainable management and restoration of water resources. This involves implementing practices and technologies that reduce water consumption and improve water availability. The goal of being water positive is to positively impact aquatic ecosystems, ensuring more water is conserved and restored than used or consumed."[9]
Strategies
The main strategies applied by companies and entities were presented at the United Nations Conference on Water held in New York in 2023.[10] It is assumed that by systematically following these guidelines and with long-term commitments, various companies have set goals to be water positive within 10 to 15 years. The strategies are:
- Implementing technologies and processes to reduce direct and indirect water consumption through process optimization, circularproduction, and water recycling and reuse.
- Offsetting the residual water footprint through projects that increase and improve the availability and quality of water in impacted basins, such as the construction of wetlands and algal farms, treatment plants, reforestation, aquifer recharge, rainwater harvesting systems, among other innovations.
- Investing in research and development to implement new technologies that optimize water use.
- Establishing partnerships with NGOs, local communities, and other actors to advance integrated management of shared water resources.
- Promoting a culture of water sustainability among employees and consumers through awareness programs on the responsible use of water.
- Establishing compensation incentives for the application of multiple barrier purification systems such as ultrafiltration, microfiltration, nanofiltration, reverse osmosis, ultraviolet radiation, or their combination that sustainably purify water and achieve water positive production goals.
Compensation
The water positive concept, through water purification using unconventional resources, was presented for the first time during the opening ceremony at the IDA 2022 World Congress during the “Charting Resilient Water Solutions” opening ceremony.[11]
The objective of water footprint compensation is to achieve a positive impact on global water resources. This is done by collaborating with various stakeholders to implement water purification systems in areas of scarcity, thus increasing the local supply. A more balanced trade in virtual water footprint, which is the water used to produce traded goods and services between regions, is also promoted.
Regulating this virtual water trade can improve the global efficiency of water use. Regions with abundant water resources could compensate part of the water footprint from regions with high water stress, thus helping to alleviate their dependence on virtual water imports. This two-pronged approach of increasing local supply and balancing trade between regions represents a comprehensive management of global water resources that only these decentralized treatments allow in a way similar to the carbon offset market.
The Water Benefit Standard
The Water Benefit Standard launched in 2014, was the first globally consistent standard that certified the positive socio-economic impacts of water projects. The principles and safeguards from this standard have been embedded into the broader framework of the Gold Standard registry for Water Benefit Certificates. This ensures that any project that may have implications on water quality or access, actively manages any risks.[12]
The Water Positive Think Tank (WPTT)
The Water Positive Think Tank is a non-profit organization that commenced its operations as a workgroup in 2021. On September 14, 2021 the first framework for a water credit offset program through water purification, based on carbon emission trading schemes (ETS) or cap and trade was drafted. This work aimed to support companies endorsing the UN CEO Water Mandate and committed to water positive goals by producing new water similar to carbon markets – first reducing consumption and then offsetting through seawater desalination, wastewater reuse to supplement insufficient cycles.
