Zevero Alternatives: Choosing Between a Carbon Platform and a Consultancy

If you are comparing Zevero, the alternatives worth knowing are Seedling (full-scope carbon software with a dedicated expert on every plan, made for businesses up to around 2,000 employees), Greenly (an AI-led platform with broad EU framework coverage), Watershed (an enterprise platform for large corporates and financial institutions), the SME Climate Hub (free tools and a recognised commitment for smaller firms), Carbon Trust (an established consultancy with respected assurance and labelling), and Ecologi (a climate action platform specialising in funding verified offsets) .

The table sums up each option, and the sections below go deeper.

Provider	Who they are	Strengths	Fit considerations
Seedling	Carbon management software with a named carbon expert on every paid plan, for SMEs and mid-market businesses up to around 2,000 employees.	Full-scope (Scopes 1, 2 and 3) footprints on activity data; compliance reports (SECR, PPN 006, B Corp, ISO 14064, SBTi) generated in-platform; Xero, Sage and QuickBooks integrations; certified B Corp, 500+ clients, 95% retention.	Built for SMEs and the mid-market, not large multinationals with complex multi-entity EU disclosure.
Greenly	French AI-led carbon and ESG platform with a dedicated climate expert team, leaning towards larger organisations.	Deep EU regulatory coverage (CSRD, CBAM, EUDR, VSME, SFDR); large emission-factor library; AI-assisted data collection; supplier engagement at scale.	Geared to organisations with substantial EU disclosure obligations; lighter reporting needs won't use the breadth.
Watershed	Enterprise sustainability platform (US origin) for large corporates and financial institutions.	Enterprise-grade data and AI agents; strong US disclosure coverage (CSRD, California SB 253/261); deep finance and supply-chain capability.	Scale and pricing set for Fortune 500-size organisations, not the mid-market.
SME Climate Hub	Free non-profit initiative (We Mean Business Coalition) for smaller businesses.	Free calculators, action-plan and reporting tools; the recognised SME Climate Commitment tied to the UN Race to Zero.	No dedicated expert or assured, compliance-grade reporting; aimed at smaller firms finding their feet.
Carbon Trust	Long-established global climate consultancy, assurance and labelling body.	20+ years and 350+ experts; recognised footprint labels and independent assurance; deep strategy and policy expertise.	Bespoke consultancy at consultancy rates; centre of gravity is large organisations, not a platform you own.
Ecologi	UK B Corp and offsetting specialist, increasingly offering carbon reporting too, with an affordable per-employee subscription.	Deep expertise in verified credits (Gold Standard, Verified Carbon Standard) and tree planting; easy integrations (including Shopify) to fund projects per sale; growing reporting via Ecologi Zero.	Offsetting is the core strength; measurement and reporting are newer and still building depth.

At a glance: Zevero's model

Zevero is a carbon management platform, founded in London and now with offices in Singapore and Tokyo, that builds expert support into the software rather than selling it as a separate consulting project. Data collection leans on automation. You connect your systems or upload invoices in more or less any format and language, and the platform matches the activity data to emission factors, drawing on a library of more than 200,000 across seven databases. Alongside the core corporate footprint, Zevero has added product carbon footprints, Environmental Product Declarations, ESG disclosure reporting and a B Corp audit, and it has real depth in food and drink, with a client list heavy on breweries and drinks brands. A footprint typically lands in eight to twelve weeks.

A Scope 1 and 2 plan (Zevero Lite) starts from £1,500 a year, a full Scope 1, 2 and 3 plan (Essential) from £3,500, and a compliance-focused plan with closer expert involvement (Leading) from £7,500. Product footprints, EPDs and ESG reporting are priced as separate add-ons, from £500, £10,000 and £1,000 respectively. Expert support features to some degree on every tier, and the depth scales as you move up.

It is a strong option, particularly if product-level footprints, EPDs or multi-region disclosure are on your list. A few things are worth weighing before you commit, though. The core plans are keenly priced, but the pieces that make it an all-in-one, product footprints, EPDs, ESG reporting and decarbonisation strategy, are charged as separate add-ons, so the total can climb once you build out what you need. Hands-on expert help follows a similar pattern: the £3,500 Essential plan gives you a methodology review at setup and key milestones rather than an expert actively involved throughout, which arrives on the £7,500 Leading plan. A first footprint also tends to take eight to twelve weeks, and Zevero's deepest sector experience is in food and drink, so a professional services, tech or manufacturing business may want to sense-check the fit for its own supply chain.

None of that rules it out. It just means the right choice comes down to the usual things: how big you are, what you need to report, how quickly you need it, and how much expert help you want included as standard rather than added on. Plenty of businesses would rather have a dedicated expert and the core reporting from day one, at a lower entry point, without building it up tier by tier. The six alternatives below sit at different points on exactly those questions, from free tools to enterprise platforms and old-school consultancies.

The 6 best Zevero alternatives for businesses up to around 2,000 employees

1. Seedling: carbon management software with a dedicated expert included

Best for: SMEs and mid-market teams that want expert-guided carbon data, not a one-off consultancy project

Pricing: Free entry tier plus subscription plans; see seedling.earth/pricing

Seedling is carbon management software with a named carbon expert attached to every paid plan from day one, so you get the rigour of a consultancy and the speed of a platform you log into and own. Full-scope measurement (Scopes 1, 2 and 3), calculated in line with the GHG Protocol. Spend data gets you started, but the platform is designed around activity data, inputs like energy use, mileage, commuting and supplier responses, so the footprint reflects what the business does and the numbers fall as you cut emissions rather than tracking invoices.

Your expert guides you through data collection, builds a costed plan to reduce emissions, and supports SBTi-aligned target-setting. Your footprint, targets and reports stay in a platform you own and can reuse each year in minutes. Every output is reviewed and assured by the Seedling team, and feeds straight into the reports and frameworks businesses are asked for, from SECR and PPN 006 Carbon Reduction Plans to B Corp, ISO 14064, ISO 14001, CDP and EcoVadis. Integrations with Xero, Sage and QuickBooks pull financial data in alongside the activity data, and a first footprint typically lands in two to four weeks for around a day of your team's time. Seedling is a certified B Corp trusted by 500+ businesses, with a 95% client retention rate.The entry point sits below Zevero's, and a free tier, Seedling Starter, lets you measure a first footprint before paying.

What it does well:

Full-scope GHG Protocol and ISO 14064 measurement on activity data, not just spend
A dedicated, named carbon expert on every paid plan, alongside a platform you own
Compliance reports (SECR, PPN 006, B Corp, ISO 14064, SBTi) generated in the format you need
Accounting integrations (Xero, Sage, QuickBooks), plus employee and supplier surveys
A free entry tier, Seedling Starter, to measure a first footprint before paying

They are the closest match on this list: both are UK-founded platforms with built-in expert support and client bases that extend well beyond the UK. There are, however, a few practical differences worth noting. With Seedling, a dedicated carbon expert is included from the start, as standard. By contrast, Zevero’s more hands-on, ongoing support only begins on its higher-tier £7,500 Leading plan. Seedling also offers a lower entry point, with pricing that scales according to the size and complexity of your business, making it possible to get started below the level of Zevero’s full-scope plans. Reporting is another point of difference. Seedling includes core reporting within its plans, whereas Zevero offers elements like product footprints, EPDs and ESG reporting as add-ons. Finally, there is a difference in speed: Seedling typically delivers a first carbon footprint in under four weeks, while Zevero’s process usually takes around eight to twelve.

2. Greenly: an AI-led carbon and ESG platform with broad EU coverage

Best for: Larger organisations and businesses with significant EU regulatory reporting obligations
Pricing: Subscription pricing, available on request

Greenly is a French platform used by more than 3,000 companies, with a client list that leans towards bigger organisations, Axa, Veolia, Schneider Electric and BNP Paribas among them. It pairs heavy automation, an AI assistant that speeds up data collection and a large emission-factor library, with a dedicated climate expert team included on most packages. Its real speciality is EU regulation: on top of CSRD, SBTi, CDP and EcoVadis, it goes deep on newer rules like CBAM, EUDR, the Digital Product Passport and VSME.

That regulatory reach is where Greenly is strongest, and it suits organisations carrying real EU disclosure obligations, particularly larger businesses handling complex, multi-entity reporting. If your reporting needs are lighter, a good deal of that breadth goes unused.

What it does well:

Deep EU regulatory coverage (CSRD, CBAM, EUDR, VSME, SFDR)
A dedicated climate expert team included on most plans
Large emission-factor library and AI-assisted data collection
Supplier engagement at scale for Scope 3
Strong fit for larger organisations with complex reporting

Where it differs from Zevero:

Both pair software with climate experts, so the split is one of emphasis. Greenly is organised around EU regulatory reporting and tends to serve larger organisations, where Zevero sits with growing and mid-sized businesses and leans into product footprints and food and drink.

3. Watershed: an enterprise carbon and sustainability platform

Best for: Large corporates and financial institutions with enterprise-scale reporting
Pricing: Enterprise pricing, available on request

Watershed plays at the top of the market. Its customers include more than 90 Fortune 500 companies, five of the top six US banks, and six of the top ten global private equity firms. The platform pairs a large emission-factor library with AI agents for data cleaning and analysis, and reporting geared to CSRD and California's disclosure laws (SB 253 and SB 261). Verdantix named it a leader in its 2026 report on enterprise carbon management software.

For a large, multi-entity organisation with a dedicated in-house team, this depth is hard to match. For a mid-market business, the scale, and the pricing that comes with it, is geared to a different type of buyer.

What it does well:

Enterprise-grade methodologies and a very large emission-factor library
AI agents for data cleaning, analysis and report drafting
Strong US disclosure coverage
Deep finance and supply-chain capability

Where it differs from Zevero:

Watershed is aimed at large enterprises; Zevero serves growing and mid-sized businesses. For most people comparing Zevero, Watershed is bigger and more expensive than they need.

4. SME Climate Hub: free tools to help small businesses cut carbon

Best for: Smaller businesses making a first move on a limited or zero budget
Pricing: Free

The SME Climate Hub is a non-profit from the We Mean Business Coalition, built with the Exponential Roadmap Initiative and the UN-backed Race to Zero campaign. It offers free, self-guided tools, including emissions calculators, a Climate Action Plan builder and a reporting tool, plus the SME Climate Commitment, a recognised pledge to halve emissions by 2030 and reach Net Zero by 2050 that earns UN recognition. More than 10,000 businesses have signed it.

As a free way in for a small business, it does the job. What you do not get is a dedicated expert, or assured, report-ready output for SECR, a PPN 006 plan or a detailed client questionnaire. It is made for smaller firms finding their feet, not teams with formal reporting on the line.

What it does well:

Free calculators, action-planning and reporting tools
A recognised commitment tied to the UN Race to Zero
A large global community of committed businesses
A low-risk way to start

Where it differs from Zevero:

The Hub is free and self-guided; Zevero is a paid platform with expert support and assured outputs. Plenty of businesses start with the Hub and move to a supported platform once real reporting demands land.

5. Carbon Trust: an established climate consultancy and assurance body

Best for: Large organisations, and teams that want recognised assurance or a footprint label
Pricing: Project-based consultancy pricing; free guides and reports on the site

The Carbon Trust is one of the most established names in climate action, with more than 20 years behind it, 350+ experts, and offices across several continents. It works largely with major corporates, governments and financial institutions, Bentley, Siemens, Kellogg's, Carlsberg and Amazon among them, on target setting, footprinting, decarbonisation strategy and policy. It is also well known for its assurance services and its product and organisational carbon footprint labels, which carry real recognition.

For a business that wants deep strategic advice, or an externally recognised label or assurance, the Carbon Trust is a credible choice. The considerations are those of any premium consultancy. Work is delivered as a bespoke service at consultancy rates rather than through a platform you log into and own, and its centre of gravity is large organisations rather than the mid-market.

What it does well:

Two decades of expertise and a large team of specialists
Recognised footprint labelling and independent assurance
Deep strategy, policy and market-transformation experience
Strong credibility with large corporates and governments

Where it differs from Zevero:

The Carbon Trust delivers a bespoke consultancy service, where Zevero gives you software plus support in one platform. For teams that want to own their data and reuse it each year, a platform is usually quicker and more repeatable than a consultancy engagement.

6. Ecologi: climate action platform with offsetting expertise

Best for: Businesses that want to fund verified climate projects and engage their team, with reporting alongside
Pricing: Affordable monthly subscription that scales by headcount; footprinting via Ecologi Zero.

Ecologi is a UK B Corp whose expertise is climate contributions. Its best-known product, the Climate Action Workforce, is a monthly subscription that scales with your headcount and funds tree planting and certified carbon avoidance and removal projects for every employee, all Gold Standard or Verified Carbon Standard, with monthly retirement certificates and third-party-audited planting partners. Its community has funded tens of millions of trees. A marketplace and integrations, including a Shopify app, let businesses fund a project or plant a tree with every sale, which makes it a popular way to bring climate action into a brand and get a team involved.

Ecologi has broadened well beyond offsetting. It now offers Ecologi Zero, a footprinting tool that connects to Xero, along with measurement, SBTi-aligned targets and support for frameworks like SECR, PPN 006, CSRD and CDP. The reporting side is growing, but offsetting and contributions remain where its depth and reputation sit, so it is worth being clear on which of those two jobs you most need it for.

What it does well:

Deep expertise in verified carbon credits (Gold Standard and Verified Carbon Standard) and large-scale tree planting
An affordable per-employee subscription that scales with your team
Easy integrations, including a Shopify app to fund projects per sale
A strong tool for brand-building and team engagement
A growing measurement and reporting side, including Ecologi Zero and framework support

Where it differs from Zevero:

Both cover measurement and reporting, but they come at it from opposite ends. Ecologi started with offsetting and climate contributions and has built reporting out from there. Zevero started as a carbon management platform focused on measuring and reducing emissions with expert support. Which fits depends on whether funding verified projects or building the footprint is your main priority.

How we chose these options

Every option here was assessed on how relevant it is to small and mid-sized businesses who are weighing up Zevero. We looked at four things: the quality and scope of the carbon measurement, the level of expert support included, how practical the tool is for a non-specialist team to run, and how well it matches the reporting businesses actually face. We deliberately included a spread, from free tools to enterprise platforms and consultancies, because the right answer depends on your size and what you need to report.

Frequently Asked Questions

Is Zevero a software platform or a consultancy?

Zevero is a carbon management platform with in-house experts, so you get both software and support. It covers organisational footprints, product footprints, EPDs and ESG disclosure across several regions.

What is the best Zevero alternative for a UK mid-market business?

It depends on your reporting. If you need SECR, a PPN 006 Carbon Reduction Plan, B Corp or client requests handled with a dedicated expert included, Seedling is built for exactly that. If your organisation sits at the larger end of the mid-market and your obligations are primarily EU-based, Greenly may be the best alternative. If you are a large multinational, Watershed operates at that scale.

Which option is best for measuring a carbon footprint for the first time?

For a first footprint, it helps to start with a free tool before committing to anything paid. Two good options are the SME Climate Hub, with free calculators and templates for smaller businesses, and Seedling Starter, our free entry-level tier. The difference comes when you want to go further: a supported plan adds a named expert and a system you keep, which takes the guesswork out of trickier areas like Scope 3 and gets you to a compliant, shareable footprint.

What is the difference between spend-based and activity-based carbon accounting?

Spend-based accounting estimates emissions from what you spend, using industry-average factors. It is a quick starting point because it uses financial data you already have. Activity-based accounting uses the physical quantities involved, like kilowatt hours of electricity, litres of fuel and tonnes of materials. The GHG Protocol recognises both but is clear that activity data is more accurate, and it captures real reductions because it tracks output rather than spend.

Do I have to choose between a platform and expert support?

No. Some tools give you a platform with little help, and consultancies give you help with no platform. Seedling, like Zevero, provides both, so a dedicated expert guides you while the work stays in a platform you own and can reuse each year.
