How to use the new OneStop ESG Marketplace

A company may know the sustainability problem it needs to solve without knowing which provider, technology or service to look for. It might need to measure its carbon footprint, install solar across several sites, improve supply-chain transparency or find support for sustainability reporting.

 

The OneStop ESG Marketplace relaunched on 28 September 2026 with AI search, use-case browsing, expanded company profiles, case studies and client reviews. The Marketplace now brings together 1,600+ companies across six use cases, 28 categories and 90 subcategories, giving buyers several ways to move from a business requirement to relevant solution providers.

 

OneStop ESG Marketplace AI search for providers that can help measure a company’s carbon footprint.

 

1. Search by what you need

 

OneStop AI Search lets users describe a sustainability requirement in their own words rather than beginning with a company name or having to know exactly which category it belongs to.

A user might search “Measure My Company’s Carbon Footprint” or “Install Solar Across My Sites.” The Marketplace then surfaces providers related to that requirement. If you already know the company or product you are looking for, Quick search provides a more direct route.

 

2. See how AI search works

 

Measuring a company’s carbon footprint

Suppose a sustainability team is preparing an emissions inventory. Instead of beginning with a long list of carbon accounting companies, it can search “Measure My Company’s Carbon Footprint.”

The results provide a starting set of relevant providers. Filters help narrow the search, while individual company profiles provide more information on the available offerings. The questions can then become more specific: does the solution cover corporate emissions accounting, supplier data or decarbonisation planning? Is it software, advisory support or a combination of the two? Which industries and geographies does the company serve?

The search begins with the business requirement and helps turn it into a more focused provider shortlist.

Installing solar across multiple sites

The same process works for a different requirement. An operations team could search “Install Solar Across My Sites” and then assess whether the suggested providers work with commercial properties, support projects across multiple locations, and offer services such as design, installation, monitoring or maintenance.

The requirement changes, but the process remains straightforward: describe the problem, review relevant providers, narrow the options and open the profiles that appear most suitable.

 

3. Browse by use case

 

AI search is one way to start. Buyers can also browse according to the type of sustainability work they are undertaking.

The six use cases are Reduce & Decarbonize, Measure & Report, Circular & Sustainable Operations, Food & Agriculture, Advisory & Strategy, and Remove & Offset. Each leads into more specific categories and subcategories.

A company working on emissions reduction might begin with Reduce & Decarbonize, while a reporting team could go directly to Measure & Report. Someone researching recycling, water or materials may start with Circular & Sustainable Operations.

The numbers also give a sense of the depth within these areas. Measure & Report currently includes 387 companies across nine categories, with filters covering industry, geography, certifications and reporting frameworks.

This route is useful when the broad objective is known but the organisation is still deciding which type of solution it needs.

4. Compare company profiles

 

Finding a company is only part of the research. The redesigned profiles bring more information about a provider into one place, helping buyers understand what it offers before making contact.

Depending on the information available, a profile may include products and services, industries served, geographic coverage, customer size, deployment model, pricing approach, reporting frameworks and other company information. Some listings also display structured fields such as Industry Focus, Solution Type, Frameworks and Geography, making key details easier to scan.

For a software buyer, that may mean checking how a platform is deployed, which organisations it is designed for and which reporting requirements it supports. Someone looking for consulting support may focus more on industry experience, service scope and geographic coverage.

Individual products and services can also be presented separately, giving buyers a clearer view of a specific offering rather than relying only on a general company description.

5. Check previous projects

 

Where available, case studies provide another way to assess a provider. Rather than looking only at which organisations a company has worked with, buyers can focus on the work itself: what problem was the client trying to solve, what was included in the project, what did the provider deliver and what outcomes were reported?

A case study involving a similar industry, business problem or project scope may be particularly useful. It gives the buyer more context for deciding whether the provider’s previous experience is relevant to the requirement at hand.

6. Read or leave client reviews

 

Provider profiles have a Client reviews section. Where reviews have been published, buyers can consider that feedback alongside the company’s profile, products, services and case studies.

Past clients can also contribute. Open the profile of a company you have worked with, select Write a review and submit feedback about your experience. Every submitted review is checked and verified before it is published.

For buyers, reviews add another perspective when assessing a provider. For companies, they give existing clients a way to share their experience and add independent feedback to the profile.

7. Contact the providers you want to speak with

 

Once the research has narrowed the field, provider profiles include Request Demo and Contact Provider options.

By this stage, the buyer has already had the opportunity to understand the company’s offering, look at relevant project experience and read client feedback where available. The discussion can therefore begin with questions about a particular product, service, project or business requirement rather than simply asking what the company does.

 

8. Are you a sustainability solution provider?

 

Sustainability solution providers can get listed on the OneStop ESG Marketplace and present their offering to businesses researching relevant products and services.

If your company is already listed, review the profile and make sure it clearly explains what you offer, who you serve, where you operate and the type of work you have completed. Add individual products or services where relevant, include useful case studies and invite clients you have worked with to leave a review.

A more complete profile gives prospective buyers more information when deciding whether your company fits their requirements.
