Chemical Sciences and Society (CS3)

The CS3 series, hosted by the funding agencies and chemical societies of the US, Germany, China, Japan and the UK, convenes eminent researchers from each participating country to explore frontier chemistry research and its potential application to global challenges. By design, each meeting in the CS3 series, hosted in turn by each of the organizing countries, is to focus on a particular key societal challenge, as mutually identified by meeting organizers, and the role of chemical research in addressing the challenge.

CS3 2015

The 2015 Chemical Sciences and Society Summit (CS3) will take place September 14-18 in Leipzig, Germany. Organized by the German Chemical Society, the symposium will bring together experts from the United States, United Kingdom, Germany, China and Japan to discuss chemistry and water. Chemists will identify some of the major issues affecting water including sanitation, contamination, analytical techniques to detect/measure contaminants, emerging techniques for water treatment, and methods to safely repurpose wastewater. 

ACS is pleased to lead the U.S. delegation to Leipzig to be a part of this vital conversation. More information on the summit will be forthcoming as the topic and delegation are finalized.

Past Events


5th chemical sciences and society symposia (cs3)
Delegates convene at the University of Kyoto in Narita, Japan for the 2013 CS3 Summit on "The Efficient Use of Elements"

The 5th CS3 Summit was held from September 16-19, 2013, 2014 at the University of Kyoto in Narita, Japan with the focus topic ‘The Efficient Use of Elements’. Over 30 chemists representing the five participating countries worked together to identify and clarify problems associated with the rapid increase in demand for scarce elements and proposed rational, meaningful approaches to resolving this challenge we all face. A white paper was produced with contributions from each of the participating organizations to summarize the findings of the Summit. A press conference is slated to be convened at the upcoming ACS National Meeting in San Francisco on Tuesday, August 12 from 8:30-11:30am.

2102 Chemical Sciences and Society (CS3) Summit
Delegates gather at the Argonaut Hotel in San Francisco, California for the 2012 CS3 Summit on research breakthroughs in organic materials.

The 3rd CS3 Summit took place at the Argonaut Hotel in San Francisco, California, USA on September 17-20, 2012. Representatives from five different chemical societies gathered to assess and forecast research breakthroughs in organic materials and carbon nanostructures, and how their architectures can be designed for novel electronic applications. A link to more information about the meeting can be found below.

2011 Summit for Chemical Sciences and Society
Delegates of the CS3 gathered for the 2011 Summit in Beijing China to speak about "Chemistry for Better Health"

The third annual CS3 meeting took place in Beijing, China in September 2011. The theme was “Chemistry for Better Health” and focused on advances in chemistry for modern medicine. Thirty top chemical scientists from the five participating countries assembled in Beijing to identify the scientific research required to address key global challenges, and to provide recommendations to policymakers. The initiative produced collaborative discussions the international perspective of chemistry’s contribution to human health. A white paper summarizes the outcomes of the event.

2010 Chemical Sciences and Society Summit
The topic for the 2010 Chemical Sciences and Society (CS3) Summit, held in London, UK, was sustainable materials

The second CS3 took place in London, England. Discussions on the theme, sustainable materials, led to the production of the white paper, This paper makes addresses topics such as energy conversion and storage, carbon capture, rare materials, fossil fuel replacement, and green materials.

2009 Chemical Sciences and Society Summit
Delegates from the 2009 Chemical Sciences and Society (CS3) Summit met in Kloster Seeom, Germany to discuss a "World Without Sunlight"

The focus of the first CS3 meeting was solar energy, with a meeting theme “Sunshine to Power the World”, and the meeting was held in Kloster Seeon, with Germany serving as host. The white paper, Powering the World with Sunlight includes advice from CS3 participants to policymakers, highlighting the role of chemical research in reaching solutions to energy challenges and offering advice on promising research directions for advancement in solar energy.
