The Green Chemistry Commitment’s learning objectives are designed to ensure that chemistry majors have proficiency in essential green chemistry competencies.
A group of educators in the U.S. has grown impatient with the slow headway in integrating the concepts of green chemistry and toxicology into the undergraduate chemistry curriculum. They are ready to ask academic institutions for pledges to accelerate that progress through an initiative called the Green Chemistry Commitment.
Colleges and universities that sign the commitment agree to develop goals for implementing a core set of learning objectives, says Amy S. Cannon, executive director of the nonprofit organization Beyond Benign, in Wilmington, Mass., which is leading the initiative. The objectives outline the basics of green chemistry and toxicology that students should take with them to the workplace after they graduate, Cannon says.
At the top of the list of objectives is that students should have a working knowledge of the 12 Principles of Green Chemistry. These principles, developed 15 years ago, serve as a conceptual framework to guide the design, manufacture, use, and recycling or disposal of chemical products in an economically, environmentally, and socially responsible way. Additional learning objectives include having an understanding of the molecular mechanisms of how chemicals affect human health and the environment and being prepared to communicate the benefits of green chemistry to society.
“The principles of green chemistry direct chemists toward safer, less toxic, and renewable chemistry and materials,” Cannon says. “But to advance green chemistry, a significant change must occur in how we are training the current and next generation of scientists. The Green Chemistry Commitment is an effort to unite the chemistry education community around common learning objectives that have traditionally been absent from our training as chemists.”
Many institutions have already committed significant time and financial resources to introduce green chemistry concepts into lecture courses, substitute green chemistry laboratory exercises in place of traditional labs, and use green chemistry as a research framework, Cannon says. However, a widespread, systematic approach to green chemistry education doesn’t yet exist, she notes.
For example, the American Chemical Society’s guidelines for bachelor’s degree programs provide broadly defined requirements for approved departments and graduates receiving certified degrees (C&EN, Sept. 24, page 39). Green chemistry is currently listed as a potential cross-disciplinary track that could be taught as part of the overall requirements.
Green chemistry advocates argue that green chemistry should be integrated into the foundation course work on analytical, biological, inorganic, organic, and physical chemistry, Cannon says. However, the ACS guidelines are not designed to specify the content of these courses. “Rather than waiting for a mandate to teach green chemistry principles and toxicology concepts, which might be a long time in coming, we thought we should create a mechanism for the chemistry community to commit to changing the curriculum now,” she says.
The Green Chemistry Commitment is designed to be flexible so that each institution can adopt the objectives according to its resources and capabilities, Cannon explains. For example, some departments might focus on integrating green chemistry into core lecture and lab courses, whereas others might develop separate green chemistry or toxicology courses.
Each institution’s progress in meeting the objectives will be charted in an annual report that provides an opportunity to update goals to help drive continual improvement. The reports will be evaluated by the initiative’s advisory board made up of established members of the green chemistry community, and the results will be shared with other institutions.
One university that hopes to sign on to the commitment is the University of California, Berkeley. The university is a relative newcomer to green chemistry, notes John Arnold, director of the Berkeley Center for Green Chemistry and an adviser to the Green Chemistry Commitment. UC Berkeley made its first foray into green chemistry four years ago when graduate students asked for permission to start a green chemistry and sustainable design seminar, Arnold says. The university has been rapidly expanding its efforts from there.
UC Berkeley’s green chemistry program has two focal points, he explains. At the graduate level, the department offers the seminar course and a lecture course in green chemistry. Arnold says the goal is to help the next generation of leaders in chemistry begin their careers able to include green chemistry in the courses they teach and in their research.
“At the undergraduate level, we want to weave green chemistry into the fabric of what we teach, so that undergraduate students can take these concepts with them as they go into the world as doctors, lawyers, engineers, politicians, and businesspeople,” Arnold says. To help meet that goal, UC Berkeley developed new lab experiments for its general chemistry course for nonchemistry majors, which is taken by more than 2,000 students per year—about half of all freshmen.
The Green Chemistry Commitment:
◾ Theory: Have a working knowledge of the 12 Principles of Green Chemistry.
◾ Toxicology: Have an understanding of the principles of toxicology, the molecular mechanisms of how chemicals affect human health and the environment, and how to access the resources to identify and assess molecular hazards.
◾ Laboratory skills: Possess the ability to recognize, assess, and design greener alternative chemical products and processes.
◾ Application: Be prepared to serve society in their professional capacities as scientists through the articulation, evaluation, and employment of methods and chemicals that are benign for human health and the environment.
