Information about the Presidential Green Chemistry Challenge

The Presidential Green Chemistry Challenge Awards promote the environmental and economic benefits of developing and using novel green chemistry. These prestigious annual awards recognize chemical technologies that incorporate the principles of green chemistry into chemical design, manufacture, and use.

EPA’s Office of Chemical Safety and Pollution Prevention sponsors the Presidential Green Chemistry Challenge Awards in partnership with the American Chemical Society Green Chemistry Institute® and other members of the chemical community including industry, trade associations, academic institutions, and other government agencies.

In 2015 EPA announced a new award category for a green chemistry technology that has a "Specific Environmental Benefit: Climate Change."

Throughout the 21 years of the awards program, EPA has presented awards to 109 winners. Since its inception, in 1996, EPA has received over 1,600 nominations. By recognizing groundbreaking scientific solutions to real-world environmental problems, the Presidential Green Chemistry Challenge has significantly reduced the hazards associated with designing, manufacturing, and using chemicals.

Through 2016, our 109 winning technologies have made billions of pounds of progress, including:

  • 826 million pounds of hazardous chemicals and solvents eliminated each year—enough to fill almost 3,800 railroad tank cars or a train nearly 47 miles long.
  • 21 billion gallons of water saved each year—the amount used by 820,000 people annually.
  • 7.8 billion pounds of carbon dioxide equivalents released to air eliminated each year—equal to taking 810,000 automobiles off the road.

These data are from award-winning nominations for the Presidential Green Chemistry Challenge. Adding the benefits from the nominated technologies would greatly increase the program’s total benefits.

  6. It must fit within at least one of the three focus areas of the program

If you have a question about whether your technology meets the scope of the program, please email us at or call (202) 564-8740.

1. Green chemistry technologies

Green chemistry technologies are extremely diverse. As a group, they…

  • Improve upon all chemical products and processes by reducing negative impacts on human health and the environment relative to competing technologies
  • Include all chemical processes: synthesis, catalysis, reaction conditions, separations, analysis, and monitoring
  • Make incremental improvements at any stage of a chemical’s lifecycle, for example, substituting a greener feedstock, reagent, catalyst, or solvent in an existing synthetic pathway
  • May substitute a single improved product or an entire synthetic pathway
  • Benefit human health and the environment at any point of the technology’s lifecycle: extraction, synthesis, use, and ultimate fate
  • Incorporate green chemistry at the earliest design stages of a new product or process
  • Contain a significant amount of chemistry, although they may also incorporate green engineering practices

2. Source reduction

For this program, EPA defines green chemistry as the use of chemistry for source reduction. Chemical technologies that include recycling, treatment, or disposal may meet the scope of the program if they offer source reduction over competing technologies. Read how green chemistry differs from cleaning up pollution (remediation).

3. Eligible organizations

Companies (including academic institutions and other nonprofit organizations) and their representatives are eligible for Presidential Green Chemistry Challenge Awards for outstanding or innovative source reduction technologies.

Public academic institutions, such as state and tribal universities and their representatives, are eligible for Presidential Green Chemistry Challenge Awards for technologies that prevent, reduce, or eliminate air or water pollution or the adverse health effects of solid waste entering into the waste stream.

4. Significant milestone

A green chemistry technology must have reached a significant milestone within the past five years. Some examples are: critical discovery made, results published, patent application submitted or approved, pilot plant constructed, and relevant regulatory review (e.g., by EPA under TSCA, FIFRA, or CAA; by the U.S. Food and Drug Administration under FFDCA) initiated or completed, and technology implemented or launched commercially.

5. Significant U.S. component

A significant amount of the research, development, or other aspects of the technology must have occurred within the United States. If the only aspect of the technology within the United States is product sales, the technology may not meet the scope of the program.

6. Focus areas of the Presidential Green Chemistry Challenge

Green chemistry technologies fit into at least one of the three focus areas below. Technologies that do not fit within at least one focus area may not fall within the scope of the program.

Focus Area 1: Greener Synthetic Pathways

This focus area involves designing and implementing a novel, green pathway to produce a new or existing chemical substance.

Examples include synthetic pathways that:

  • Use greener feedstocks that are innocuous or renewable (e.g., biomass, triglycerides)
  • Use novel reagents or catalysts, including biocatalysts and microorganisms
  • Use natural processes, such as fermentation or biomimetic syntheses
  • Are atom-economical
  • Are convergent syntheses

Focus Area 2: Greener Reaction Conditions

This focus area involves improving conditions other than the overall design or redesign of a synthesis. Greener analytical methods often fall within this focus area.

Examples include reaction conditions that:

  • Replace hazardous solvents with solvents that have less impact on human health and the environment
  • Use solventless reaction conditions and solid-state reactions
  • Use novel processing methods that prevent pollution at its source
  • Eliminate energy- or material-intensive separation and purification steps
  • Improve energy efficiency, including reactions running closer to ambient conditions
  • Reduce greenhouse gas emissions

Focus Area 3: The Design of Greener Chemicals

This focus area involves designing and implementing chemical products that replace more hazardous products.

Examples include chemical products that are:

  • Less toxic than current products
  • Inherently safer because they reduce the likelihood or severity of accidents
  • Recyclable or biodegradable after use
  • Safer for the atmosphere (e.g., do not deplete ozone, form smog, or contribute to climate change)

Selection Criteria

Nominated chemistry technologies that meet the scope of the program will be judged on how well they meet the following three selection criteria:

A. Science and innovation

The nominated chemistry technology should be innovative and of scientific merit.

The technology should be, for example:

  • Original (i.e., never employed before) and
  • Scientifically valid, that is, can the nominated technology or strategy stand up to scientific scrutiny through peer review? Does the nomination contain enough chemical detail to reinforce or prove its scientific validity? Has the mechanism of action been clarified via scientific research?

B. Human health and environmental benefits

The nominated chemistry technology should offer human health and/or environmental benefits at some point in its lifecycle from resource extraction to ultimate disposal. Quantitative statements of benefits are more useful to the judges than are qualitative ones.

The technology might, for example:

  • Reduce toxicity (acute or chronic) or the potential for illness or injury to humans, animals, or plants
  • Reduce flammability or explosion potential
  • Reduce the use or generation of hazardous substances, the transport of hazardous substances, or their releases to air, water, or land
  • Improve the use of natural resources, for example, by substituting a renewable feedstock for a petrochemical feedstock
  • Save water or energy
  • Reduce the generation of waste, even if the waste is not hazardous

C. Applicability and impact

The nominated chemistry technology should have a significant impact. The technology may be broadly applicable to many chemical processes or industries; alternatively, it may have a large impact on a narrow area of chemistry. Commercial implementation can support the applicability and impact of a technology. Nominations for pre-commercial technologies should discuss the economic feasibility of the technology.

The nominated technology should offer three advantages:

  • A practical, cost-effective approach to green chemistry
  • A remedy to a real environmental or human health problem
  • One or more technical innovations that are readily transferrable to other processes, facilities, or industry sectors

Selection Process


A. How to enter

1. Basic information

  • The deadline for nominations for the 2017 Presidential Green Chemistry Challenge is December 31, 2016. Awards for 2017 will be presented in the summer of 2017.
  • Self-nominations are typical.
  • There is no entry fee.
  • There is no standard entry form, but nominations must meet certain requirements or EPA may reject them.
  • You may nominate more than one technology, but you must submit a separate, stand-alone nomination for each one. Multiple applications of the same general technology are most likely to win an award if you combine them in a single nomination.
2. Format
Nominations must have:
  • No more than eight pages, including the cover page
  • Single-spaced, 12-point type, but references, captions, and footnotes may be as small as 10-point type
  • Margins of at least 1 inch when printed on 8½-by-11-inch paper
Nominations may include:
  • Chemical reactions, tables, graphs, charts, photographs, diagrams, and other illustrations within their eight pages
  • Text or illustrations in color, but the judges may read the nominations printed in black and white; therefore, nominations should not require color for interpretation.
  • Links to published articles, patents, etc. Nominations should not rely on information in links to present their technology because judges may not follow any links.

Structure of submission materials: 

The first page must be a cover page with the:
  • Technology title and date of the nomination
  • Primary sponsor(s): the individual or organizational owner(s) of the technology. For academic nominations, the primary sponsor is usually the principal investigator. For nominations with more than one sponsor, each co-sponsor should have had a significant role in the research, development, or implementation of the technology
  • Contact person with full mailing address, email address, and telephone number: the one individual with whom EPA will communicate regarding the nomination. For academic nominations, the contact person is usually the principal investigator. For other nominations, the contact should be a project manager or other technical representative. We add the person listed as the contact to the list of subscribers for our electronic newsletter. Periodically, we email reminders and updates about the program to those on our list. You may opt out at any time.
  • Contributors (optional): those individuals or organizations that provided financial or technical support to develop or implement the technology
The second page should contain the following information:
  • Technology title
  • A sentence indicating whether the nominated technology is eligible for the small business award, academic award, both, or neither.
  • The name (or number) of the EPA award focus area that fits your technology. One-or two-line description of the most recent milestone for the nominated technology and the year it occurred. Only one milestone and year are required; the milestone must be within the last five years.
  • One or two sentences describing the U.S. component of the technology: the research, development, implementation, or other activities of the technology that occurred within the United States.
  • An abstract (not to exceed 300 words) that describes the nominated technology, the problem it addresses, and its benefits. Include the degree of implementation (or commercialization) of the technology and any quantitative benefits such as the amount (or potential amount) of hazardous substances eliminated, energy saved, carbon dioxide emissions eliminated, water saved, etc. EPA plans to publish these abstracts in its annual Summary of Award Entries and Recipients. If you are nominating a technology you submitted in a previous year, you may use the abstract previously published by EPA in whole or in part. Links to previous annual summaries of award entries and recipients are available on the Green Chemistry award winners page.

The information in this section should fit on page 2, but you may continue on page 3 if necessary.

The remaining pages should show how your technology meets both the: The judges will look for detailed explanations of:
  • The problem (environmental or human health risk) that your technology addresses, its importance, and how your technology solves it.
  • The chemistry of your new technology, emphasizing its novelty and scientific merit. To be eligible for an award, your technology must include a significant chemistry component. Include as much nonproprietary detail as possible, such as the specifics of your chemistry and detailed reaction pathways. Consider using chemical structure diagrams to describe your chemistry. You may include patent numbers or references to peer-reviewed publications, but add only the most important, recent ones because references take space away from other details of your technology.
  • Realized or potential benefits and drawbacks. These may occur across all stages of your technology’s lifecycle: from feedstocks to manufacture, use, and the ultimate disposal of the product. Include the human health, environmental, and economic benefits of your technology such as toxicity data and quantities of hazardous substances reduced or eliminated. If you have not done a full lifecycle analysis, discuss the impacts of your technology across the lifecycle to the extent you know them.
  • How your technology compares with any other technologies that address the same problem. Comparing the cost, performance, and environmental profile of your technology with any competing technologies may demonstrate the broad applicability of your technology.
  • Current and planned commercialization. For example, is your technology currently on the market? Are you building a pilot or manufacturing plant? If your technology is or is about to be commercially available, also discuss the regulatory status of any novel chemical substance or organism under any applicable laws such as TSCA, FIFRA, CAA, or FFDCA. EPA must assure that winning technologies comply with these laws.

3. Submitting your nomination to EPA

Submit an electronic copy of your nomination in a format so that EPA can select and copy text. Include the primary sponsor’s name in the file name. You may want to submit your nomination as a .pdf file to minimize possible reading errors, but EPA accepts and can read all common file types. Send the electronic copy by email to If you encounter problems submitting your nomination electronically, please contact us at or (202) 564-8740.
