Fresh water: a dwindling supply and a growing demand.

Pie Chart

Although 97% of the world is covered in water, only 3% is fresh water. Of the world's small supply of fresh water, less than 1% is available for human consumption. Yet the demand for fresh water is growing twice as fast as the global population.

Experts say that total water usage in the U.S. has tripled over the last 30 years while the population has increased by only 50%.1 Globally, one out of six people does not have access to fresh water and one out of three do not have access to sanitized water. The problem is especially serious in Asia, where 36% of the world's drinkable water must somehow support 60% of the world's population.2

World Water Supply

As if fresh water isn't scarce enough, much of it is wasted due to aging infrastructure. In the U.S., up to 20% is lost to leakage. Replacing the U.S. water infrastructure may cost between $300 billion and $1 trillion. At the current rate of investment, it would take 900 years to get the job done.3

The problem affects more than just drinking water. In northwest China, for example, factories have closed because there isn't enough water. Chinese government economists estimate that environmental troubles generally shave 10% off the country's gross domestic product every year.4

This confluence of issues —

  • Finite supply of freshwater,
  • Challenges of global population growth,
  • Modernization of developing populations,
  • Need for technology to maximize water supplies,
  • Infrastructure to support its transport and storage

— lead many to conclude that water is a critical area for resource development. As such, the water sector represents a significant investment opportunity. Since we are left with little choice but to grow and increase spending in the water sector, the time may be ripe to invest in a water fund.

Investing throughout the entire water network.

The Calvert Global Water Fund invests in more than just water. It also invests in a massive network of water-related systems, services and technologies involved in all stages of water management — from ground to people and back to ground again. Key areas include water and wastewater utilities, water pumps and valves, consulting and engineering to build water infrastructure, and technologies to maximize water supplies through purifying, desalination and metering.

Stage 4: Sewage and Sanitization Water Soruces: Ground or Surface Stage 3: Residential, Commercial, Industrial, Agricultural Use Stage 2: Filtration and Disinfection Process

There is investment opportunity in the utilities, the infrastructure and the technologies that are being used to manage our interaction with this scarce and valuable resource throughout each stage. Here are some examples: water collection, water storage, the infrastructure to move water through pipes from one area to another, desalination, innovations that reduce usage or emphasize re-use of water and systems that disinfect water prior to its discharge back into the environment.

Water. A timely and attractive investment.

As the world's population surges, its collective thirst for water — for drinking, agriculture, industry, and maintaining a high standard of living — will continue to surge as well. Yet the world faces a dwindling supply of fresh water.

The precarious situation related to the supply and demand for fresh water creates a significant need for global investment in sustainable methods of obtaining and delivering water. It also presents a significant growth opportunity for investors. Looking at the charts below, while recent performance for these representative markets has been negative, the water sector has outperformed the Global and U.S. Markets for the year-to-date, one-year, three-year and five-year time periods.

Indices are unmanaged and do not reflect the payment of advisory fees and other expenses associated with an investment in a fund. Investors cannot directly invest in an index.

A Word About the Investment Risks. Calvert Global Water Fund is subject to the risk that stocks that comprise the water sector may decline in value. The water industry can be significantly affected by common economic trends, such as the availability of water, the level of rainfall and consumption, and other climatic events, in addition to environmental considerations, taxation, and government regulation (including the cost of compliance). The Fund is non-diversified and may invest more of its assets in a smaller number of companies; therefore, gains or losses on a single stock may have greater impact on the Fund. The stock markets in which the Fund invests may also experience periods of volatility and instability. Consequently, the Fund may tend to be more volatile than other mutual funds. Lastly, foreign investments involve greater risks than U.S. investments, including political and economic risks and the risk of currency fluctuations.

Water is needed for so much more than just drinking so Calvert wants to make sure that all pieces of the water puzzle are thought about and considered.

A pure water fund.

Unlike other water funds, 80% of the Calvert Global Water Fund's assets are derived from companies in the water sector. Calvert defines a company in the water sector as one in which at least 50% of its business is related to water.

Water is a human right.

We believe that all of us have a right to clean water. When you invest in the Calvert Global Water Fund, you invest in that right. Calvert strives to invest only in companies that support this objective.
