Carbon offset providers sell, certify or broker credits that pay for emissions cuts elsewhere, and the buyers range from a family covering a flight to an airline with compliance duties.
This guide ranks sellers whose prices or counterparty are visible first, then asks what each organisation actually does, what it states about itself and what it leaves out.
Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.
In short
What carbon offset providers software does
A carbon offset provider funds emission-reduction projects, issues or registers the credits they generate, and lets companies or individuals buy and retire them against their own footprint.
To rank carbon offset providers tools we asked, in turn, how much work setup takes, what it truly costs, whether data can be taken back out, whether leaving is possible, and who the product suits. Top three places belong to challengers outside the best-known brands whenever possible, and incumbents follow from four. The reasoning behind the five tests, and behind having no score out of ten, is set out on the how we work page.
Offsets priced openly per pound, tonne, gallon and kilowatt-hour on one page
Ranked #1 of 12 in Best Carbon Offset Providers in 2026.
Published pricingElsewhere
The business plan starts at a stated sum per employee per month, which suits a payroll-sized budget better than a one-off footprint. Custom project sourcing, carbon footprinting and sustainability disclosures are listed as business services, and calculators cost nothing to use.
Water credits and energy certificates sit beside carbon offsets, which helps a buyer covering several claims. Check currency and the invoicing entity before ordering, since neither is stated.
What stands out
Per-employee business plan
Water restoration certificates
Renewable energy certificates
Where it costs you
Prices show a dollar sign without a currency code, so invoicing currency needs confirming.
The household monthly plan appears without a price, and no country or owner is stated.
Right for
Companies wanting a per-head offset budget with prices visible before contact
Wrong for
Buyers who need a named home country first
Not stated by the vendorPublished per-unit prices for offsets, water and energy certificates; business plan billed per employee each month
Swiss foundation selling climate projects, consulting, training and emissions calculators
Ranked #2 of 12 in Best Carbon Offset Providers in 2026.
Pricing on requestEurope
Corporate services are laid out as a sequence: calculate emissions, reduce them, train employees, finance climate protection and communicate the engagement. Education programmes and CO2 calculators sit next to the project portfolio.
The legal name is Foundation myclimate, which gives a buyer a clear counterparty. What the page does not show is any rate per tonne, so comparing cost with other sellers means asking directly.
What stands out
Foundation structure
EcoCloud carbon software
Employee climate training
Where it costs you
No per-tonne rate, plan name or trial appears on the home page.
EcoCloud is mentioned only through a webinar, so its scope is unverified.
Right for
Organisations wanting education and consulting alongside the offsets they buy
Wrong for
Buyers wanting a price list before talking to anyone
SwitzerlandNo amounts or per-tonne rates on the home page; offsets, consulting and EcoCloud software are described without plans
Non-profit compensating flights and events, with recurring and gift contributions
Ranked #3 of 12 in Best Carbon Offset Providers in 2026.
Pricing on requestElsewhere
The home page offers flight compensation, a chosen amount of CO2, an event calculator on a separate subdomain, a recurring contribution and a gift option.
Its stated rule is to compensate only unavoidable emissions, in CDM Gold Standard projects. That narrow scope makes it easy to understand and hard to stretch: a company wanting a footprint across all operations will need another tool alongside it.
What stands out
Flight compensation
Event CO2 calculator
Recurring climate contribution
Where it costs you
Pages read were in German and showed no prices, so cost depends on the calculators.
The imprint text could not be read, so country and legal form are unverified.
Right for
Travel-heavy teams and event organisers wanting to offset flights and conferences
Wrong for
Companies needing accounting, reporting or supplier tooling beyond travel
Not stated by the vendorNo prices or plan names shown on the German home page; amounts come from its flight and event calculators
Nonprofit shop selling offsets from cookstove, methane and biochar projects
Ranked #4 of 12 in Best Carbon Offset Providers in 2026.
Pricing on requestElsewhere
The named functions are a shop, calculators for flying, travel and business, Offset Travel, For Business and Site Visits. Project types run from cookstoves to biochar, so buyers can pick a method rather than accept a blended portfolio.
Bulk deals from 1,000 tonnes go through a contact route instead of a price list. The notice about a faulty payment gateway is a practical risk to anyone planning a same-day purchase.
What stands out
501(c)3 nonprofit
Cookstove and biochar projects
Offset travel calculator
Where it costs you
A banner reported payment gateway problems on the day the page was read.
No plan tiers or currency appear, and bulk pricing needs contact from 1,000 tonnes.
Right for
Small buyers choosing a specific project type from a nonprofit shop
Wrong for
Anyone who needs to pay instantly or by subscription
Not stated by the vendorShop-based purchases; bulk project pricing handled by contact from 1,000 tonnes, with no currency or tiers displayed
Business climate platform covering emissions reporting, credits and storefront integrations
Ranked #5 of 12 in Best Carbon Offset Providers in 2026.
Pricing on requestElsewhere
Three parts are named: Reduce handles Scope 1, 2 and 3 emissions, Restore funds verified credits and nature work, and Report covers science-based targets and communication.
Integration is the unusual angle, with an API and a Shopify app for embedding contributions into sales, and a Public Impact Ledger showing verified data. The cost of all this is invisible from the home page, which offers only a get-started button.
What stands out
Scope 1, 2 and 3 reporting
Shopify app and API
Public Impact Ledger
Where it costs you
No price, plan or imprint appeared on the page read.
The 16,000 business figure is the vendor's own claim and was not independently checked.

Munich company pairing a carbon accounting hub with consulting and certified projects
Ranked #6 of 12 in Best Carbon Offset Providers in 2026.
Pricing on requestEurope
The offer joins accounting, reduction, certified projects and communication in one service. ClimatePartner Hub is the central place for emissions data, with an API option, and the page mentions help for CSRD or SBTi reporting.
Amazon Climate Pledge Friendly and a Transparency Page appear as communication tools. The cost of the combination is not visible, since the page sends buyers to a form and a customer manager.
What stands out
ClimatePartner Hub
CSRD and SBTi support
Transparency Page
Where it costs you
No price or trial is shown, and the contact form leads to a customer manager.
The page read was the German home page, with limited detail on plan scope.
Right for
Mid-sized companies wanting software, consulting and offsets from one German supplier
Wrong for
Buyers wanting to test a product before speaking to sales
GermanyNo prices shown; enquiries go to a contact form and a customer manager follows up
Independent NGO certifying climate projects and keeping a public credit registry
Ranked #7 of 12 in Best Carbon Offset Providers in 2026.
Pricing on requestEurope
The Impact Registry is described as a public, tamper-proof record, which gives a buyer a place to look up what exists. For developers it adds a document and certification workflow.
The Swiss address is in the footer. Treat it as a reference point for judging other sellers, because the pages read show no price list or checkout for a buyer purchasing offsets.
What stands out
Project certification
Impact Registry
Digital Assurance Platform
Where it costs you
The home page shows no buyer pricing, plan or trial.
It certifies and registers projects rather than selling offsets to individual buyers.
Right for
Buyers checking whether a project sits under an independent standard
Wrong for
Companies wanting to buy and retire credits in one sitting
SwitzerlandNo buyer pricing, plan names or currency on the home page; aimed at project developers and credit buyers
Nonprofit operating the Verified Carbon Standard and a project registry
Ranked #8 of 12 in Best Carbon Offset Providers in 2026.
Pricing on requestElsewhere
Programmes listed include a jurisdictional and nested REDD+ framework, a Scope 3 Standard, community and biodiversity standards, SD VISTA and a plastic waste reduction standard.
The registry is entered through a login for developers, and a Project Hub offers a digital gateway API. None of this is a retail storefront. Use it to look up what a seller's credit claims, since no price or checkout appeared on the home page.
What stands out
Verified Carbon Standard
Verra registry
Scope 3 Standard
Where it costs you
No fees, plan or trial appear, and its country is not stated on the page read.
The tooling is built for project developers, not for retail or corporate offset purchases.
Right for
Buyers verifying a credit's standard and registry record before purchase
Wrong for
Anyone who wants a basket to add offsets to
Not stated by the vendorNo fees, plan names or currency stated on the home page; the registry serves project developers
Climate consultancy developing carbon projects and running a digital platform
Ranked #9 of 12 in Best Carbon Offset Providers in 2026.
Pricing on requestElsewhere
The home page ties carbon credits to wider work: audit-ready climate disclosures, net zero plans, CORSIA compliance and renewable energy procurement. Its own project development and a digital platform are mentioned.
The footer reads 2026 South Pole and claims offices in more than 20 countries without naming where it is based. Expect a scoping exchange rather than a basket, because nothing on the page shows prices.
What stands out
CORSIA compliance units
Net zero planning
Sustainability reporting
Where it costs you
No price or trial appears, and the page names no home country.
The offering is consultancy-led, which is more than a small buyer may need.
Right for
Airlines and large buyers needing CORSIA units plus net zero planning
Wrong for
Small buyers wanting a quick, itemised offset purchase
Not stated by the vendorNo buyer prices or plan names on the home page; engagement is through the consultancy
Services company for corporate climate strategy and carbon credit access
Ranked #10 of 12 in Best Carbon Offset Providers in 2026.
Pricing on requestElsewhere
Four offerings are listed: the Patch System, Embedded Climate Strategy, Radius as a network, and Offtake, which is described as funding climate tech and securing carbon credit access.
Entry is through a strategist call or an intake form rather than a basket. The page read was cut short, so its ownership and country remain unknown. Treat it as a services relationship, with scope and cost agreed case by case.
What stands out
Embedded climate strategy
Offtake agreements
Radius network
Where it costs you
No price, plan or trial is shown, and the page read did not state a country.
The services are enterprise-oriented and the page read was truncated in the fetch.
Right for
Enterprises wanting an embedded strategist alongside long-term credit purchasing deals
Wrong for
Small teams wanting to buy a few tonnes today
Not stated by the vendorNo prices or plans shown; calls to action are an embedded strategist and an intake form
Operating software for carbon credit developers selling spot and forward credits
Ranked #11 of 12 in Best Carbon Offset Providers in 2026.
Pricing on requestElsewhere
Catalyst covers the selling side: inventory, pricing, project content, payment and delivery for spot and forward credits. Direct sales tools include a branded buyer portal, a proposal builder and automated responses to RFPs.
Everything points to developers rather than purchasers. A buyer should know that a supplier may use this kind of system, but would not use it. Cost is hidden behind a demo booking.
What stands out
Buyer portal
Proposal builder
Forward credit management
Where it costs you
The product is built for project developers, so buyers get no direct offset shop.
No price, trial or country is shown, and the footer carries only a 2024 notice.
Right for
Project developers who need to quote and deliver credits to buyers
Wrong for
Companies simply wanting to buy and retire offsets
Not stated by the vendorNothing priced on the site; visitors can book a demo or press get started
Offsetting service built on a screened portfolio of carbon projects
Ranked #12 of 12 in Best Carbon Offset Providers in 2026.
Pricing on requestElsewhere
The approach is a portfolio across project methods and regions, with an overcompensation mechanism to cover uncertainty in both projects and footprints. Compensate claims a 10% pass rate among screened accredited projects.
A customer quote mentions footprint calculation and portfolio management, though no platform is described. The page also points to articles on scaling down, and its footer shows 2021, so ask whether new orders are accepted before planning around it.
What stands out
Project screening
Portfolio approach
Overcompensation buffer
Where it costs you
The page lists articles about scaling down operations and a footer dated 2021.
No prices, plan terms or software platform are described.
Right for
Buyers who value portfolio screening, once current availability is confirmed
Wrong for
Anyone needing guaranteed ongoing service and published prices
Not stated by the vendorNo prices shown; the page lists no plan or trial terms
A carbon offset provider funds emission-reduction projects, issues or registers the credits they generate, and lets companies or individuals buy and retire them against their own footprint. Rather than compare features, settle the following points one after another.
01
Decide whether you need a published price
Only 1 of the 12 print a price; 11 quote per organisation. Comparable without a sales call: Terrapass.
02
Look at where the vendor sits
Jurisdiction is a buying criterion here. The 12 vendors are spread over 3 countries (Elsewhere 9, Europe 3), and the home country determines which disclosure rules bind them.
Offset sellers, registries and software are three different things in carbon offset providers
A buyer typing carbon offset providers into a search box lands on three kinds of organisation. Terrapass, Cool Effect and Atmosfair sell offsets to buyers. Gold Standard and Verra run standards and registries, so they define and record credits rather than selling them to you. Cloverly and Patch sit on the supply side, with software and services for developers and enterprises.
Mixing these up wastes weeks: you cannot check out on a registry, and a developer platform will not retire a tonne for your company. Sort every shortlisted name into seller, standard or supplier tooling first, then compare only like with like. The registry sites are still useful, since they let you look up what a seller's credit claims.
Label each shortlisted name as seller, standard or developer tooling
Do not expect a checkout on Gold Standard or Verra
Use registries to look up a credit the seller names
Reading prices when most providers publish none
Only Terrapass shows numbers on its home page: personal, business, water and energy certificates by unit, and a business plan per employee. Myclimate, Atmosfair, ClimatePartner, South Pole, Ecologi and Patch show no amounts on the pages read, and Cool Effect shows bulk pricing only through contact from 1,000 tonnes.
That makes comparison hard, because a per-tonne rate from one seller may include consulting and another may be a bare credit. Ask every vendor for the same four items in writing: the price per tonne, the project type behind it, the registry or standard, and any added fee for software or reporting. Terrapass prices carry a dollar sign without a currency code, so confirm the currency before you compare it with a euro quote.
Request price per tonne, project type and standard in writing
Ask whether consulting or software is bundled into the rate
Confirm currency, since Terrapass shows a dollar sign only
Matching scope: flights, whole-company footprint or compliance units
Scope decides the shortlist more than price does. Atmosfair concentrates on flights and events, with a recurring contribution and gifts, so it suits a travel budget but not a supply-chain footprint. Ecologi and ClimatePartner cover reporting across Scope 1, 2 and 3 emissions with software, and ClimatePartner mentions CSRD and SBTi support.
South Pole lists CORSIA compliance units, which matter only to buyers with airline obligations. Myclimate sits between them, with calculators, training and consulting around its projects. Write down what you actually must do this year, such as offset a conference, report to a regulator or fund a project, and discard any provider whose pages do not mention it by name.
Write down whether you need flights, full footprint or CORSIA units
Check that the provider names your regulation, such as CSRD
Drop providers whose pages never mention your use case
Checking the provider is still trading and who stands behind it
In this market a polished site proves little, so check who the counterparty is. Myclimate names Foundation myclimate in Zurich, ClimatePartner names its GmbH in Munich, and Gold Standard lists a Chatelaine, Switzerland address. Terrapass, Ecologi, Verra and Atmosfair state no country on the pages read, and Compensate shows a 2021 footer and articles about scaling down operations.
Cool Effect's page carried a payment gateway warning when read. Before paying, find the legal entity on the invoice, the date of the last update and a way to reach a person. Ask also where the credit is retired and in whose name, so the claim you publish is one you can show.
Find the legal entity and address before paying
Look for recent dates and signs of reduced activity
Ask where and in whose name credits are retired
What goes wrong most often when buying carbon offset providers software
Buying from a registry or standard body and expecting a retail checkout, when Gold Standard and Verra serve developers and certifiers.
Comparing a bare per-tonne rate from Terrapass with a bundled quote from ClimatePartner or South Pole as if both covered the same work.
Choosing a flight-focused seller such as Atmosfair when the real obligation is company-wide reporting across all scopes.
Relying on a provider's own totals, such as Ecologi's 16,000 businesses or Compensate's 10% pass rate, without asking for the evidence.

Frequently asked questions
6 answers
What is the best carbon offset providers in 2026?
First of 12 on this page is Terrapass. Terrapass puts its numbers on the home page: personal offsets by the thousand pounds of CO2, business offsets by the metric tonne, and a business plan that starts from a stated amount per employee each month.
It also sells water credits and renewable energy certificates. The page names no country or owner, and the household plan carries no price, so a family buyer still has to dig.
Which carbon offset providers tools publish their pricing?
1 out of 12 state a price model on their own site:
Terrapass: Published per-unit prices for offsets, water and energy certificates; business plan billed per employee each month.
The remaining 11 sell by quote.
Is there a free carbon offset providers tool?
No. None of the 12 offer a usable free tier.
Where are these carbon offset providers vendors established?
Across 3 countries (Elsewhere 9, Europe 3):
Terrapass: Not stated by the vendor.
Myclimate: Switzerland.
Atmosfair: Not stated by the vendor.
