    U.S. Bottled Water Consumption on the Rise: What Does It Mean?

    By Rebecca Olson, Communications Associate

    July 21, 2016

                           Steven Depolo

    If last year’s bottled water sales are any indication, the sale of bottled water in the U.S. this year will likely surpass that of soda. In 2015, Americans bought the equivalent of five bottles of water per citizen each week. Meanwhile, the sale of soda fell 1.5 percent, reaching the lowest level per person since 1985.

    While there is a positive side to this picture — certainly water is a healthier beverage to consume than sugary carbonated drinks — the consumption of bottled water has negative environmental and economic repercussions, as outlined in Peter Gleick’s 2010 book Bottled and Sold: The Story Behind Our Obsession with Bottled Water. As Gleick explained, each bottle of water is the product of a vast amount of energy and contributes to plastic waste.

    Given the negative impacts of bottled water consumption, the sale of bottled water has been banned on some college campuses and in national parks ranging from the Grand Canyon to Zion National Park. In 2015, San Francisco joined Concord, Massachusetts in banning the sale of single-use plastic water bottles (however unlike Concord, the San Francisco ban only covers sales on city property).

    Like bottled water, tap water is a healthy alternative to sugary drinks, and it’s a lot cheaper too. Despite concerns over the quality of water infrastructure in the U.S., tap water is overwhelmingly safe to drink, better monitored and regulated than bottled water, and costs fractions of a penny per glass. In fact, bottled water is about 2,000 times more expensive than tap water.

    The act of purchasing a bottle of water seems like an inconsequential, isolated choice, yet a vast number of Americans making this choice each day has a significant effect. Efforts to cut bottled water usage are a positive step, but any significant change will involve the widespread commitment of communities, governments, and municipal water providers to provide a safe and reliable domestic water supply, expand access through new, modernized public water fountains, and educate the public about the benefits of drinking tap water. The Pacific Institute is continuing to work on these key priorities.

  • ERW Opinion: On Methods for Assessing Water-Resource Risks and Vulnerabilities

    By Peter Gleick, President Emeritus and Chief Scientist

    July 29, 2016

    Much more can and should be done with new data and methods to improve our understanding of water challenges, says Peter Gleick.

    As populations and economies continue to expand and as anthropogenic climate change accelerates, pressures on regional freshwater resources are also growing. A wide range of assessments of water pressures has been produced in recent years, including the regular updates from the United Nations World Water Development Reports (WWAP 2003, 2006, 2009, 2012, 2014, 2015), the biennial assessment The World’s Water (Gleick et al 1998–2015), the Aqueduct water stress datasets produced by the World Resources Institute (WRI 2015), and numerous other efforts to develop quantitative water measures and indices. The development of such methods has become increasingly common in recent years in order to help measure progress and evaluate the impacts or effectiveness of water policies and practices. The new letter in this volume of Environmental Research Letters by Padowski et al (2015) offers another opportunity to evaluate freshwater threats and vulnerabilities.

  • Diablo Canyon Nuclear Power Plant, courtesy PG&E

    National Geographic ScienceBlogs: Diablo Canyon, Climate Change, Drought, and Energy Policy

    By Peter Gleick, President Emeritus and Chief Scientist

    June 24, 2016

    The announcement that Pacific Gas and Electric (PG&E) will close the Diablo Canyon Nuclear Plant when its current operating licenses expire in 2025 has caused what can only be described as consternation mixed with occasional conniptions among the nuclear industry and some strongly pro-nuclear groups.

    That’s understandable. Diablo Canyon is aging, but is not the oldest nuclear plant in the fleet and PG&E could have chosen to push for a renewal of the license to continue operations for many more years. Diablo Canyon’s two reactors are also California’s last operating nuclear plants, following the closure many years ago of Rancho Seco near Sacramento, and more recently, the last of the San Onofre reactors. As such, the closure is symbolic of the broader woes of the nuclear power industry in the United States, which has been unable to build new reactors and is seeing the current reactors being shuttered, one by one.

    Fits and Starts at the Salton Sea

    By Michael Cohen, Senior Research Associate

    The fortunes and prospects of California’s Salton Sea have ebbed and flowed over the years. Currently, the Sea is enjoying renewed attention and funding, after almost a decade of neglect and indifference. The State of California is poised to dedicate $80 million to efforts to protect and revitalize (a small portion of) the Salton Sea, prompted in large part by a fast-approaching tipping point that will see a dramatic shrinking of the Sea, devastating its rich ecosystem and imperiling the health of hundreds of thousands of people in the region.

    National Geographic ScienceBlogs: Global Droughts: A Bad Year

    By Peter Gleick, President

    April 27, 2016

    Populations around the world face many severe water challenges, from scarcity to contamination, from political or violent conflict to economic disruption. As populations and economies grow, peak water pressures on existing renewable water resources also tend to grow up to the point that natural scarcity begins to constrain the options of water planners and managers. At this point, the effects of natural fluctuations in water availability in the form of extreme weather events become even more potentially disruptive than normal. In particular, droughts begin to bite deeply into human well-being.

    National Geographic ScienceBlogs: Water, Security, and Conflict: Violence over Water in 2015

    By Peter Gleick, President

    February 17, 2016

    Since its founding in 1987, the Pacific Institute has worked to understand the links between water resources, environmental issues, and international security and conflict. This has included early analytical assessments (such as a 1987 Ambio paper  and this one from the journal Climatic Change) of the risks between climate change and security through changes in access to Arctic resources, food production, and water resources, as well as the ongoing Water Conflict Chronology – an on-line database, mapping system, and timeline of all known water-related conflicts. In 2014, an analysis of the links between drought, climate change, water resources, and the conflict in Syria was published in the American Meteorological Society journal Weather, Climate, and Society.

    Moving from Theory to Practice: A Synthesis of Lessons about Incentive-Based Instruments for Freshwater Management

    by Heather Cooley, Michael Cohen, and Matthew Heberger

    February 8, 2016

    There has been growing interest in applying incentive-based instruments, such as pollution charges and tradeable permits, to address the twin challenges of accessing enough freshwater to meet our needs while also preserving the well-being of freshwater ecosystems. These instruments use direct or indirect financial incentives as motivation to reallocate water or to reduce the health and environmental risks posed by an activity. But what do we know about how they have actually performed?

    Huffington Post: The Most Important Water Stories of 2015

    By Peter Gleick, Brett Walton, and J. Carl Ganter

    February 4, 2016

    Water was a Top Risk on the 2015 Global Agenda

    In early 2015, participants at the World Economic Forum, a who’s who of the political and business elite, ranked water crises as the top global risk. Water was also a key factor in the adoption by the United Nations General Assembly of the Sustainable Development Goals (SDGs), a blueprint for international development over the next 15 years. Ensuring safe drinking water and sanitation for all by 2030 is one of six water goals for the SDGs. In December at the UN climate change conference in Paris, world leaders acknowledged the instrumental role that water will play in a warming planet. Water security was included in the response plans of most nations and was at the core of numerous debates and side agreements.

    Sanition and Water for All Partner Perspectives: One Year On: Companies and Respect for the Human Rights to Water and Sanitation

    By Mai-Lan Ha

    January 29, 2016

    2015 was a historic year for sustainable development. The world came together and adopted the Sustainable Development Goals (SDGs), a new framework that will guide development for the next 15 years. The 17 SDGs cover a range of topics from health to education to equality and environmental protection. Underpinning the achievement of these goals is the importance of water. As such, water has its own dedicated goal (Goal 6) and is also integrated into a number of other related goals, such as those on health, wellbeing, and biodiversity. Critical to achievement of SDG6 will be the important role that businesses must play and the need to ensure that the rights to water and sanitation are met. As such, a year ago, the CEO Water Mandate and Shift released Guidance for Companies on Respecting the Rights to Water and Sanitation. The Guidance is the first comprehensive document that lays out how businesses can meet their responsibilities to respect the rights by incorporating them into existing water management practices, policies, and company cultures.
