For the last two decades, carbon credits have been one of the most recognizable environmental markets in the world. Companies have purchased carbon credits to offset greenhouse gas emissions, support conservation projects, and demonstrate progress toward climate goals. However, a new sustainability trend is emerging within the technology sector: water stewardship.

As artificial intelligence, cloud computing, semiconductor fabrication and hyperscale data centers continue to expand, water is becoming one of the most important resources in the digital economy. Furthermore, the deficit between demand and available supply of freshwater continues to grow. While carbon emissions remain a global concern, many technology companies are beginning to focus on a different challenge—how to reduce, replenish, and restore freshwater resources. This shift is creating growing interest in water credits and water replenishment programs that could eventually become as significant as carbon credits.

The Growing Water Challenge in Technology

Technology companies are increasingly recognizing that water scarcity poses both environmental and business risks.

Unlike carbon emissions, which disperse  atmospherically, water issues are local. A gallon of water consumed in a drought-stricken region can have a far greater impact than the same gallon used in a water-abundant area. This localized nature makes water stewardship highly visible to communities, regulators, and investors – but difficult to standardize as a tradable commodity.

As a result, major technology companies have begun adopting "water positive" goals. A water-positive company aims to replenish more water than it consumes through conservation, recycling, watershed restoration, groundwater recharge, and other replenishment projects.

Microsoft has committed to becoming water positive by 2030 and reports investments in more than 100 water replenishment and access projects globally. Amazon Web Services (AWS) has also committed to becoming water positive by 2030 and reports significant progress toward that goal through water efficiency improvements, recycled water use, and replenishment projects.

What Are Water Credits?

Water credits are market-based instruments designed to quantify and reward activities that improve water resources. Depending on the program, a water credit may represent a specific volume of water restored, conserved, treated, reused, or returned to a watershed.

Several emerging frameworks already exist. Examples include Water Restoration Certificates® (WRCs), watershed replenishment credits, and water sustainability credits. These programs allow organizations to financially support projects such as:

• Groundwater recharge

• Wetland restoration

• Watershed protection

• Rainwater harvesting

• Water reuse systems

• Leak reduction programs

• Irrigation efficiency improvements

• Wastewater treatment upgrades

The goal is similar to environmental credit markets generally: direct private capital toward projects that generate measurable environmental benefits.

Why Water Credits Appeal to the Tech Industry

‍

1. Water Is Becoming a Critical Resource for AI

Artificial intelligence requires massive computing infrastructure. The rapid construction of new data centers has increased attention on energy consumption and water use simultaneously.

While renewable energy procurement has become common among major technology firms, water availability remains a growing operational constraint in many regions. Water credits provide a potential mechanism for companies to invest directly in local water resilience.

‍

2. Water Has Local and Visible Impacts

One criticism of some carbon offset programs has been that benefits can be difficult for the public to see or verify. Water projects often produce highly visible outcomes, including restored rivers, replenished aquifers, improved wetlands, and expanded community water access.

This local connection can make water investments easier for stakeholders to understand and support.

3. Investors Are Paying More Attention to Water Risk

Financial institutions increasingly evaluate water-related risks when assessing long-term investments. Water scarcity, drought, infrastructure limitations, and regulatory restrictions can affect business operations across many industries.

As environmental reporting evolves, companies are being asked to disclose not only carbon footprints but also water footprints. This trend may increase demand for verified water stewardship projects.

‍

4. Carbon Markets Face Ongoing Credibility Challenges

Carbon credits remain an important climate tool, but the voluntary carbon market has faced scrutiny regarding project quality, verification methodologies, permanence, and additionality. Industry organizations continue working to strengthen standards and improve transparency.

Water credit programs face their own challenges, but many proponents argue that volumetric water benefits can be measured more directly in certain applications, particularly when tied to specific watersheds and restoration projects.

Could Water Credits Actually Eclipse Carbon Credits?

Today, carbon markets remain significantly larger and more established than water credit markets. Carbon credits benefit from decades of regulatory development, international frameworks, registries, and corporate adoption.

Research published in ACS ES&T Water notes that standalone water credit markets remain relatively small and have not yet demonstrated the scale achieved by carbon markets. However, researchers also note increasing interest in water-focused environmental finance and the potential for future growth.

Rather than replacing carbon credits entirely, water credits may develop alongside them. Many experts expect companies to pursue both carbon and water strategies as part of broader  initiatives.

For technology companies in particular, the future may involve dual goals:

• Net-zero or low-carbon operations  

• Water-positive operations  

As AI infrastructure expands and freshwater resources become increasingly valuable, water stewardship may evolve from a sustainability initiative into a core business strategy.

The Future of Environmental Markets

The next decade could see a significant expansion of environmental markets beyond carbon. Biodiversity credits, nature credits, and water credits are all attracting growing attention from corporations, investors, and policymakers.

Technology companies are uniquely positioned to accelerate this transition because of their large infrastructure footprints, substantial capital resources, and increasing exposure to water-related risks.

Whether water credits ultimately rival carbon credits remains uncertain. What is clear is that water is rapidly becoming one of the defining sustainability issues of the century. As data centers, AI systems, and cloud computing continue to grow, investments in water restoration and replenishment may become just as important as investments in renewable energy and carbon reduction.

The companies that lead in water stewardship now may help shape the next generation of environmental markets, that deliver a transparent and easily quantifiable impact. .
