What is a GIIRS Rating

GIIRS Ratings provide comprehensive and comparable ratings of a company’s social and environmental performance, using the B Impact Assessment.

Can I share my B Impact Report on my webpage

Yes. We encourage you to share your B Impact Report and your experiences with other business owners. See how Ian Martin Group (from Oakville, Canada) shared their results: Learning from the B Impact Assessment»

IMPORTANT: You are allowed to share the score on your webpage, although it must be noted that the score not been reviewed or verified.

Which year of data should I use to complete the Assessment

The past twelve months or trailing twelve months is the recommended reporting period.

We recommend using the a 12 month period that most closely reflects the company’s operation as of today but is easy for your company to report consistently on. As a result, if using the last Fiscal Year is easier, we would encourage your company to use this period.

What types of organizations should take the Assessment

Any for-profit business.

The Assessment is intended to be used by ANY for-profit businesses entity. The Assessment is designed for all different types of businesses, including manufacturers, retailers, and service companies, and companies of varying size, from zero employee sole proprietorships to 10,000+ employee multi-national corporations. While the Assessment is customized to reflect practices that vary across these different industries, sizes, and markets, the overall Assessment is standardized so as to create an even playing field among all groups.

Although the Assessment is not suited to measure the impact of non-profit organizations, real-estate development projects, governments, or other entities that are not operating as an individual businesses, there are many ways these institutions can interact with the B Impact Assessment.

If I use the Assessment, does our company have to become a B Corp? What is a B Corp

No. The Assessment is a free public good provided by B Lab. Simply taking the Assessment does not automatically make a company a B Corp nor does it obligate the company to pursue B Corp Certification. There are a few additional steps, beyond using the B Impact Assessment, that a company must take to achieve B Corp Certification. Learn More»

Where can I download a PDF of the Assessment
Please tell us a bit more about the type and size of your business so that we generate a PDF version of the Assessment that is relevant to your business (there are well over 40 different versions of the Assessment).

Although the PDF is a good way to get oriented to the Assessment, we strongly recommend using the Assessment online. The online Assessment will provide definitions and examples for each question, a B Impact Report that is scored based on your company’s responses so that you can compare it against benchmarks.

Working online will also allow you to engage multiple employees to work on the same Assessment easily and allow you to save your work so that the data is not lost for future years.

Who develops the standards

The standards are created and revised by the Standards Advisory Council (SAC), a group of independent experts in business and academia.  Learn more about SAC members and their role, here

Although the SAC creates the standards, we invite all interested to provide feedback to the standards. The best way to submit your feedback is to log into the B Impact Assessment and select “Leave Feedback” next to each question. If you are interested in learning about updates and opportunities to provide feedback as drafts are made available for testing and public comment, please subscribe to our V6 distribution list.

The Assessment also goes through a private and public beta period in which feedback is collected and integrated into final versions. Expert working groups are convened in order to explore our specific issues more closely in an objective manner. The Assessment is updated every three years in order to accommodate new and innovative practices, respond to the feedback of its users, and to more accurately assess the impact of all types of businesses.

In addition, B Lab has Regional Advisory Groups whose mandate is to deepen the engagement of regional experts in improving the Standards of the B Impact Assessment. Currently, B Lab has advisory groups in Latin America, East Africa, Australia and UK which provide constructive feedback and recommendations to B Lab and our Standards Advisory Council ( SAC) on regional specific issues. Learn more about the Regional Advisory Groups members here.

Who in our company should complete the Assessment

Anyone that is interested, regardless of their title or tenure with the company.

We recommend appointing one person as a lead; this individual typically completes a first draft of the Assessment and then convenes a supporting team to assist.

The most common types of individuals involved with the Assessment include CEOs, CFOs, HR Managers, COOs, Associates, Interns.

Employees who have less visibility into the operations of the company tend to be advocates for the idea of measuring what matters instead of direct contributors (ie. Marketing/Communications Director, Technology Dept, Quality Assurance, Designers, Board Members, etc).

What will I need to prepare before completing the Assessment


For your first (baseline) Assessment, we recommend that you provide estimates for each answer and mark questions as “Revisit This” if you are unsure about your answer; you will find that this is the easiest way to complete and still get a rough B Impact Score.

Thereafter, it may be helpful to use the following to assist you in answering questions:

  • Company’s financials. It may be helpful to have either a Profit & Loss Statement or your accounting system (e.g. Quickbooks) open.
  • Vendor Ledger with amount spent in the 12 months. This will help you answer many questions related to Suppliers.
  • Product bill of materials or Client/Project list from the past 12 months. This may help answer many questions in the “Impact Business Models” section.

How does this relate to other impact measurement systems

In general, the B Impact Assessment provides a judgment (via an objective, comprehensive rating) on how significant a company’s current impact is.  The B Impact Assessment is commonly confused with reporting systems or definition frameworks that detail how a company should go about collecting that impact data, but not necessarily provide a judgment on how significant that company’s impact is.

For example, the Global Reporting Initiative (GRI) or IRIS are platforms that are likely to define specific way to report impact metrics;  As an example, they may define how to best report a company's carbon emissions, so that all carbon reports in the future can be easily comparable to each other (ie. Company X is responsible for producing 30,000lbs of carbon, based on its direct emissions from its plant and its electricity purchases).  IRIS and GRI definitions and reporting standards are a critical part of the B Impact Assessment.   

As a result, a GRI or IRIS indicator is more likely to tell you that the company is reporting its emissions according to best practice.  On the other hand, the B Impact Assessment aims to evaluate whether the company has either increased or decreased its emissions relative to the company’s revenues or relative to the practices of other businesses, because this disctinction helps a growing number of consumers, investors, and institutions who want to support businesses who put their values into action.

The B Impact Assessment simply builds upon the important work that other organizations and industry groups are doing to define and measure impact.
