Sustainability Certifications: Easy Guide for Consumers & Sellers [2024]

Sustainability certifications are everywhere! Any conscious consumer has seen those little logos on everything from apparel to coffee, skincare, appliances, and even building materials.

Reliable, third-party certifications are a great way to differentiate products and companies that take their environmental and social responsibilities seriously.

The problem is that many certifications do not involve any kind of external assessment and rely on a company’s self-reported sustainability and ethical practices.

While some of these companies will honestly deliver excellent work, others may bend the truth to meet the requirements and continue operating.

Then some companies shamelessly engage in ‘Greenwashing’ to impress their customers and increase their profits while taking no steps at all to improve their environmental or social impact.

So, how do you know which certifications are legit and which ones are less-than-reliable? How do you spot Greenwashing?

If you’re a maker, seller, or service provider, how do you know which sustainability certifications to choose so as not to harm your brand reputation?

In this guide, we’re going to cover exactly what sustainability certifications are, why they’re important, the different types, and how to choose credible, reliable ones.

Then we will show you 10 certifications to look out for so that you can be assured that you’re making the best choices for your brand or your purchase.

Let’s dive right in!

What Are Sustainability Certifications?

Sustainability certifications are voluntary certifications issued by an independent, second-, or third-party organization to a company, product, or service. To be certified, the company needs to demonstrate that their business practices and products meet specific criteria to demonstrate that they’re committed to good environmental, social and ethical practice.

Sustainability certifications are:

  • Voluntary: in contrast to legal requirements and standards, sustainability certifications are usually voluntary and are not issued by governments or industry authorities. This may, and should, change going forwards as more and more governments recognize the importance of incorporating sustainability and climate issues into policy.
  • Independently Standardized and Issued: the criteria, standards, and requirements for certification are developed by independent third parties. These may be a group of experts from the same industry or a collaboration between industry experts and external experts or consultants knowledgeable about the issue being assessed and certified.
  • Fairly Assessed: certifications are issued to companies based on a fixed set of industry-specific standards. These are realistic and achievable within that industry, which levels the playing field for applicants. Only companies that meet the minimum requirements are certified. Some certifications have different levels that denote how well the company scores and how many of the criteria are met at the time of assessment.
  • Verifiable, Credible, and Transparent: certifications are verified by an independent third party, which makes them more robust and reliable. To be credible, a certification must be issued by an independent party or auditor. Certifications that rely on self-assessment and self-reported results are less reliable.
  • Market Driven: voluntary suitability certifications are not regulated by governments and are market-driven. This means that they’re often less rigorously assessed and that criteria can be flexible or more easily achievable than most government regulations allow.

Globally, there are over 600 certifications relating to environmental sustainability, social responsibility, and ethical, fair labor practices. Numerous certifications relate to animal welfare and cruelty-free practices.

Depending on the type of business and the nature of its products, a single entity may hold numerous certifications that relate to different aspects of its business.

Let’s look at why sustainability certifications are important and how they benefit companies and consumers alike:

Why Are Sustainability Certifications Important?

Sustainability certifications are important because they drive good practice, encourage transparency and require accountability. There are benefits for both consumers and the makers/sellers of products and services.

Benefits of Sustainability Certification for Consumers

  • Quick and easy way to identify products and services that meet your preferences and align with your values
  • Easy way to identify products that have multiple criteria you’re looking for without having to do research on the product or read the fine print
  • Simple way to determine if a product or service has been vetted and accredited by an independent third-party
  • Quick way to identify how committed a business is to the values and practices they claim in their marketing (as opposed to vague, sweeping statements and outright greenwashing)

Benefits of Sustainability Certifications for Makers and Sellers

  • Great way to assess your impact in the environmental, social, and ethical spheres by seeing how well you meet criteria that relate to your specific industry. This also allows you to improve your practices.
  • Reach your ideal customers by showing them clearly and quickly that you care about the same things they do.
  • Increase trust and credibility for your brand by showcasing your commitment to best practices and are not afraid to have a third party assess your business and products.
  • Simple way to demonstrate transparency and showcase your commitment to accountability
  • Increased sales and profits – a recent survey by GreenPrint found that “64% of Americans are willing to pay more for sustainable products but most (74%) don’t know how to identify them. According to the findings, 78% of people are more likely to purchase a product that is clearly labeled as environmentally friendly”

Sustainability certifications help consumers quickly identify the products/services that want to buy. They help them see at a glance that a company is committed to issues that align with their values.

Now that we have seen why sustainability certifications are important, let’s look at the most common types of certifications:

Different Types of Sustainability Certifications

Broadly, sustainability certifications relate to environmental, social, and ethical issues.

Different certifications may relate to very narrow and specific aspects within each of these broad areas. This is why many companies hold numerous certifications that relate to different aspects of their business or only to specific product lines and not the company as a whole.

The three main types of sustainability certifications are:   

  1. Environmental: these certifications relate to a wide range of environmental impacts such as resource management, carbon, and greenhouse gas emissions, manufacturing methods and pollution, materials sourcing and farming methods, waste management, circularity, etc. This is possibly the broadest category and many companies will have numerous environmental certifications.
  2. Fair Trade and Ethical Labor: these certifications relate to fair economic practices and fair labor practices. They ensure that fair prices are paid for goods from developing nations, fair wages are paid to workers, and that companies do not use unethical labor practices like child, slave, or indentured labor.
  3. Animal Welfare and Animal-Free: these certifications relate to the ethical treatment of animals. They include cruelty-free products that are manufactured without cruelty to animals, animal testing or killing of animals and vegan/animal-free for products that contain no ingredients of animal origin.

There are hundreds of different certifications relating to each of the three categories above. Some are international, while others are specific to one country or region.

Some are highly credible and involve rigorous, external, assessment and strict compliance, while others involve self-assessment and self-reporting, vague requirements, or lax standards.

Here are 10 sustainability certifications that are highly regarded and considered to be credible, verifiable, and transparent certifications:

Final Thoughts on Sustainability Certifications and Conscious Shopping

Sustainability certifications are an important tool to guide businesses to do better in terms of their environmental, social, and ethical impacts.

They’re also a quick and easy way for consumers to identify products and companies that fulfill their requirements as conscious consumers.

Trustworthy certifications that involve external, third party, evaluations, and ongoing assessment are the most reliable and credible certifications to choose from.

They help us avoid greenwashing and differentiate the businesses that are truly committed to meaningful sustainability practices, from those who just want to cash in on sales from consumers who care.

However, not all certifications are accessible and affordable for smaller brands and businesses. This does not mean those businesses are not doing good. In fact, your small, local supplier is often going to be your most sustainable option!

It is important to reach out and find out what their policies are and to evaluate the information they provide to see how transparent it is – they might not have a formal certification but still be a great choice!

Frequently Asked Questions

What are sustainability certifications?

Sustainability certifications are voluntary certifications issued by an independent, second-, or third-party organization to a company, product, or service. To be certified, the company needs to demonstrate that their business practices and products meet specific criteria to demonstrate that they’re committed to good environmental, social and ethical practice. Check out the full guide for more info.

Are sustainability certifications the same as eco-labels?

Yes and no. Eco-labels are the little stamps or logos that you see on products. These often denote sustainability certification but not all eco-labels are from a legitimate certification body. Some companies will make their own eco-labels or use eco-labels that require no assessment or evaluation. That is why it is better to go by sustainability certification than just an eco-label that you see. Check the full guide for more on how to find trustworthy certifications.

Are Sustainability Certifications Trustworthy?

Some certifications are highly trustworthy and some are completely fraudulent. A trustworthy sustainability certification will have transparent information about the standards they use, how they assess an applicant and how they monitor and evaluate members after the initial accreditation. They will use external, often expert, auditors and do not rely on honesty and self-assessments to determine a company's impact on the environment. Read the full guide for more info on selecting trustworthy certifications.

How much does it cost to get a sustainability certification?

In general, most certification bodies require some kind of payment. This may be a once off fee or an ongoing membership fee. The cost varies significantly and can be prohibitive for smaller companies or those in developing nations. Many certification bodies have a sliding scale where membership fees are determined by revenue or business size and location. Read the full guide for more info.
