The Six Classes is a visionary program of the Green Science Policy Institute, whose aim is to reduce the use of harmful chemicals in consumer and other products. It focuses on entire classes or groups of chemicals of concern, rather than phasing out problematic chemicals one at a time.

This approach of tackling entire groups of chemicals is needed because more than 80,000 chemicals are used in the U.S. Many have not been well studied and their impacts on human and environmental health are not understood. Even so, some chemicals known to be harmful are commonly found in consumer products. Moreover, when a harmful chemical is phased out, often after years of research and advocacy, the replacement may be a “chemical cousin” with similar structure and potential for harm.

The Six Classes approach can prevent such “regrettable substitutions” and accelerate reductions in toxics use.

In its work on each of the Six Classes, the Green Science Policy Institute convenes scientific experts, motivates needed studies, and publishes research results in peer-reviewed journals. Its findings are communicated widely, as part of its work for science-based change and for moving towards safer chemicals and/or technologies. A key element of the approach is to bring together scientists and decision-makers from business, government, academia, and nonprofits to develop coordinated strategies for reducing the production and use of chemicals of concern.

At face value, cabinetry may seem to be made of one type of wood, but its construction is much more complex. Many prefabricated cabinets are built using a combination of three or more wood composites and veneers, which typically use toxic glues containing formaldehyde, a known human carcinogen.

By comparing the material contents and construction in prefabricated cabinets, we created a spectrum that indicates the relationship between affordability and health. We typically consider the health effects during all phases of product development, but these diagrams are focused on the health effects during installation and inhabitation.

Currently, prefabricated cabinets are composed of 5%-30% healthier materials. Designers can increase this percentage by requesting manufacturers to build with NAF (no added formaldehyde) composite woods. This often comes with an increased price. Our Composite Wood Product and Spec Guidance gives a range of healthier substitutions.

GreenScreen® for Safer Chemicals is a method of comparative Chemical Hazard Assessment (CHA) that can be used for identifying chemicals of high concern and safer alternatives.  GreenScreen was developed by and is a project of Clean Production Action.

The Framework Manual introduces, in a structured way, various facets of green and sustainable chemistry, with the intention to foster learning, reflection and scale up action based on a common global understanding of the concept. It features an organizing framework that unpacks various topics relevant for green and sustainable chemistry literature. The Manual is setting objectives and guiding considerations from green and sustainable chemistry, as well as an innovation and research framework are offered to stimulate stakeholder action at various levels and in different settings. Ultimately, the Manual seeks to promote innovation that unveils the full power of chemistry, and is compatible with, and supports implementation of global sustainable development goals and targets. The range of topics covered in the Manual have been identified following a review of the green and sustainable chemistry literature, the 2019 UNEP report on best practices in sustainable chemistry, and the second edition of the Global Chemicals Outlook (GCO-II). Resources permitting, the Framework Manual will be complemented by specific manuals, covering selected topics of interest to stakeholders. The Manual is structured alongside the elements of the conceptual framework “Advancing sustainability through green and sustainable chemistry” which was developed through a consultative process and is introduced below. Chapters 2, 3 and 4 address the question of: “Why” is green and sustainable chemistry needed and “What” does it aim to achieve, and in which specific innovation areas. Chapters 5, 6 and 7 focus on enabling tools and measures to advance green and sustainable chemistry (the “How”). These action-enabling elements range from promoting life cycle approaches, to strengthening research and innovation policies and programmes. An important cross-cutting topic is the need to scale up awareness raising and education initiatives at all levels that bring the green and sustainable chemistry agenda to potential actors, through formal and informal education.

The Global Minimum Transparency Standard (GMTS) is a tool for companies to disclose hazardous chemicals in their products throughout the whole product lifecycle.  It will help achieve equal access to information for all stakeholders, irrespective of country and within and outside the supply chains. It is a step toward stricter regulation or even a complete phase-out of hazardous chemicals leading to global human health and environmental safety.
