Certification Process

How do I apply for certification?

Visit our Certification page to fill out a Certification Interest Form.  Our Customer Success team will contact you within 2-3 business days. You can also contact us here.

What are the fees associated with certification?

A number of factors affect the certification fee, including the types and number of products or services on the application. Our Customer Success team is happy to provide you an estimate. Contact the team here or visit our Certification page to submit a certification interest form.

How long does the certification process take?

The certification review process for a full product generally takes between 2-3 months, once you submit all of the required documentation. Factors that help reduce the overall time include being prepared and familiar with the standard, providing complete information early in the process, and using the client portal and information templates.

What documentation do I need to submit for my product?

Specific requirements vary based on your product type, but in general, Green Seal reviews information related to your formula, performance testing, manufacturing, packaging, marketing materials, and labels.  For a detailed view of the process, see this certification project flowchart.

What if a standard does not exist for my product/service?

If you do not see a standard that fits your product or service, please contact us. We will be happy to discuss your needs.

Can we apply for certification for a product that is not yet being manufactured?

You can apply and work through part of the evaluation process, but some required information can be gathered only once the product is being manufactured/produced.

Do we have to meet all of the requirements in the standard or just a percentage, to be certified?

All of the requirements of the standard must be met. Green Seal standards are pass/fail. Your Certification Reviewer will work with you collaboratively until all of the requirements are met for certification.

What happens after I submit the Certification Interest Form?

How does Green Seal handle confidential information?

Green Seal takes confidentiality very seriously, and confidentiality protocols and agreements are an important piece of the certification process.

Green Seal Standards

Who decides what requirements go into the standards?

Our environmental scientists evaluate the major health and environmental impacts of a product category and develop initial draft criteria based on that evaluation. We then solicit input from a broad variety of stakeholders to help ensure relevance and feasibility and refine optimal achievement thresholds for the criteria. This input is incorporated into the final draft set of criteria, which is released for public comment for a minimum of 60 days. We hold as many rounds of public comment as necessary to overcome any sustained opposition to proposed criteria. Staff then finalize standard criteria using collected input.

Who are the stakeholders participating in the standard development process?

We invite manufacturers, raw material suppliers, distributors, retailers, product users, purchasers, regulators, researchers, trade groups, health and environmental groups, other NGOs, advocates and anyone else who may be affected by the products or their use.  Our process is open to the public and anyone who wants to participate is welcome!

How Does Green Seal Develop impact evaluations for certified products and Services?

When developing or revising standards, our environmental scientists evaluate the greatest health and environmental impacts that occur across all phases of the life cycle of the product or service using published research sources and stakeholder feedback. We then develop standard criteria so that certified products or services mitigate those impacts to the greatest extent possible. The intent is to develop criteria that are feasible but reflect environmental and health leadership compared to conventional products, practices, and spaces. For example, on a life cycle basis, the major impacts from the production of sanitary paper products include deforestation, the emission of greenhouse gases from production and disposal of virgin fibers, and pollution from chlorine compounds used in bleaching. Green Seal certification requires 100% recycled fiber content, as well as a chlorine-free bleaching process – and these attributes result in reductions of negative health and environmental impacts 

As a result of this process, Green Seal allows products to make pre-approved claims in conjunction with the Green Seal trademark that are supported by the scientific and stakeholder research performed during the life cycle evaluation phase of standard development. Green Seal reviews any other claims made in conjunction with Green Seal trademarks, and any claims determined to be misleading as to the extent or nature of Green Seal certification result in appropriate action, which may include termination of the product certification.

How often does Green Seal update the standards?

Green Seal re-visits each standard every three years or as needed. If we notice a significant change in the market, or if a stakeholder highlights a major shift in the market, and we see that shift being adopted by a significant minority (15-20% of the market), then we will announce a Standard Revision.
