ESG investing – water scarcity

Water supplies are running low, and fears that reservoirs will run dry are increasing. While water shortages are leaving many with dwindling supplies, there are innovative companies helping to preserve, treat and recycle water.

Water crisis the planet is facing today

When the well is dry, we know the worth of water

Benjamin Franklin

2 billion

people drink water contaminated by feces across the world today1

2 thirds

of the world's population endure severe water scarcity at least one month a year today2

2.4 billion

with no access to sanitation facilities in the world today3


could be displaced by water scarcity around the world by 20304

21 cities

in India will run out of groundwater by 20205


of India's 1.34bn population will have no access to drinking water by 20306

This will be exacerbated further as rapidly growing urban areas place heavy pressure on neighboring water resources. With every continent now suffering from increasing water scarcity, the impact of climate change, population growth and intensive agriculture, along with over-use, misuse and abuse of water are all beginning to have an impact.

Companies can no longer view water as a free, non-exhaustible resource, and those in water-intensive sectors simply can't ignore water planning in their business risk analysis.

Accessing the opportunities these challenges provide

At UBS Asset Management, we find investment opportunities with innovative companies delivering solutions to the world’s most pressing sustainability challenges.

Ecolab is one of them. With customers in nearly 3 million locations in more than 170 countries, Ecolab is a global leader in water treatment, cleaning and sanitizing solutions and has consistently gained market share in recent years with more than a third of sales originating from emerging markets.

We first invested in Ecolab in our Long Term Themes strategy in 2016 and it remains one of our Top 10 holdings.

Estimates show that the global water market is currently worth more than USD 600bn annually. The biggest category, with 35% of the market, is wastewater treatment (water utilities), and the remaining 65% is water equipment (for water exploration, distribution and treatment like Ecolab).

Ecolab support their customers in improving the water efficiency of their operations, notably thanks to digitalization of its solutions. Ecolab's product impact assessment highlights how they:


171 Billion Gallons of Water


1 Million Foodborne illness


12 Trillion BTUs of Energy

Our analysis of Ecolab business projects show that overall operating margins would improve from 15% today to 19% by 2020 driven by additional cost savings programs, leverage and the sale of new higher margin products.

We continue to believe Ecolab is an industry leader in developing new effective solutions that will help customers improve operations and create a positive environmental impact to the challenges of tomorrow.

Investment opportunities from water scarcity

  • The global water crisis requires tailored, local water scarcity and quality solutions
  • Short-term measures taken by government to mitigate the water crisis include water supply rationing
  • Long-term measures include water price increases, taxation and revision of water supply licenses
  • Companies with attractive valuation that provide water management solutions are interesting investment opportunities.

UN SDG Goal 6

Ensure availability and sustainable management of water and sanitation for all.

Goal 6 of the United Nations Sustainable Development Goals is aimed at tackling water and sanitation.

Goal 6.3 target: By 2030, improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally

Goal 6.4 target: By 2030, substantially increase water-use efficiency across all sectors and ensure sustainable withdrawals and supply of freshwater to address water scarcity and substantially reduce the number of people suffering from water scarcity

It is at the very core of sustainable development and critical to the survival of people and the planet.

This goal not only addresses the issues relating to drinking water, sanitation and hygiene, but also the quality and sustainability of water resources worldwide.


A world leader in water treatment, cleaning and sanitizing solutions

At the largest industry event, Data Centre World, in Asia last year, Ecolab discussed sustainable solutions to address the fresh water crisis and how data centres have successfully reduced fresh water consumption.

“Ecolab touches 1.5 billion digital users daily through our water treatment programs,” said Kah Min Chen, vice president and managing director, Ecolab Thailand, Indochina and Philippines.

As demand for data centres surges in Asia, automated water performance systems such as 3D TRASARTM Cooling Water Technology, monitors the cooling system and delivers excellent results, which support Asia’s data centre growth through sustainable water use.

Across the globe, 40,000 3D TRASARTM units have been deployed to over 16,000 customer sites.
