Nine platforms, what each is actually built for, and where Climes does not fit.
Written by the Climes team. Vendor descriptions are based on each vendor's own public materials, verified August 2026. Corrections: growth@climes.io.
India-focused carbon and ESG platforms include Climes (Carbon-OS), Updapt, StepChange, Sprih, Breathe ESG, Newtral and The Sustainability Cloud, alongside global platforms such as Persefoni and Watershed. The right choice depends on your trigger: BRSR Core assurance, a CBAM request from an EU buyer, PCAF financed emissions, or broad ESG reporting. Carbon-specialist tools go deeper on evidence and auditability; ESG suites go wider across E, S and G metrics.
We build one of the platforms below, so read our take with that in mind. To keep this useful rather than promotional, every vendor description is drawn from that vendor's own public positioning as of August 2026, we say plainly which situations we are not the right choice for, and we date the page so you know when it was last verified.
The market splits into three shapes. Carbon-specialist platforms (Climes, Sprih, Newtral) focus on emissions data depth: activity data, factor libraries, and audit trails. ESG suites (Updapt, Breathe ESG, StepChange) cover the full E, S and G disclosure surface, including workforce and governance metrics that BRSR also asks for. Single-framework tools (The Sustainability Cloud for CBAM) go deep on one regulation only.
Positioning from each vendor's public materials, August 2026.
| Platform | Built for | Strongest when | India framework depth |
|---|---|---|---|
| Climes (Carbon-OS) | Carbon compliance with a line-level evidence trail | The number must survive an assurer, an EU buyer or a regulator | BRSR Core, CBAM, PCAF, SBTi, CCTS, ISO 14067 |
| Updapt | ESG data management and reporting suite | You need E, S and G disclosure in one system across geographies | BRSR plus global ESG frameworks |
| StepChange | Carbon, ESG and climate risk | Financial services: financed emissions and climate-risk analytics | BRSR, PCAF-aligned modules |
| Sprih | Carbon accounting and decarbonisation | Scope 1-2-3 measurement with reduction planning | GHG inventory, net-zero pathways |
| Breathe ESG | ESG data collection and reporting | Indian mid-market starting structured ESG disclosure | BRSR-oriented reporting |
| Newtral | AI-led carbon accounting and ESG reporting | Automation-first emissions measurement | GHG inventory, ESG reporting |
| The Sustainability Cloud | CBAM-specific compliance for Indian exporters | CBAM is your only problem | CBAM only, by design |
| Persefoni | Global enterprise carbon management | Multinationals reporting under CSRD, ISSB, SEC-style regimes | Global frameworks; India-specific regimes are not the core focus |
| Watershed | Global enterprise climate platform | Large multinationals with dedicated climate teams | Global frameworks; India-specific regimes are not the core focus |
Reasonable assurance reaches the top 1,000 listed entities in FY 2026-27. You need every reported figure traceable to a source document, or assurance becomes a rebuild. Carbon-specialist tools with evidence ledgers fit; if you also need S and G metrics in the same filing, pair with or choose an ESG suite.
CBAM's definitive regime went live on 1 January 2026; certificate sales open 1 February 2027 and the first declaration is due 30 September 2027. You need product-level embedded emissions in the format an EU importer can file. Climes and The Sustainability Cloud both address this directly.
Financed emissions under PCAF, with data-quality scores per asset class. StepChange and Climes both build for this; check which asset classes each covers against your book.
If you need a single suite covering workforce, safety and governance disclosures alongside carbon, an ESG suite such as Updapt or Breathe ESG is a better starting point. If you run an in-house LCA team modelling thousands of SKUs in specialist LCA software, you may not need a carbon platform at all. And if you want a one-off consultant-written report rather than a system, none of the platforms on this page, ours included, is the economical answer.
Annual pricing is quote-based across the market. Indicatively, India-focused platforms typically run from a few lakh rupees per year for a single-entity GHG inventory to substantially more for multi-entity, assurance-ready deployments; global enterprise platforms are usually priced above India-focused ones. Ask every vendor for the assurance-support and implementation cost, not just the licence.
Consultants can produce the filing. The difficulty is reasonable assurance: an assurer asks for the source document behind each of the nine Core attributes. If those trails live in spreadsheets and inboxes, every assurance cycle is a rebuild. Software earns its keep by keeping the evidence trail continuously, not by writing the report.
ESG suites manage the full disclosure surface: environmental, social and governance metrics, questionnaires and report generation. Carbon accounting platforms specialise in the emissions number itself: activity data ingestion, emission factors, methodology per framework, and auditability. Listed Indian companies often need both capabilities; the question is whether one tool does each job well enough.
Only if it keeps one underlying emissions dataset and renders it per framework. BRSR Core needs entity-level intensity metrics, CBAM needs product-level embedded emissions, SBTi needs a target-aligned inventory. Platforms that treat these as separate modules force you to reconcile three versions of the truth. Ask to see the same tonne traced into all three outputs.
For Indian exporters of iron and steel, aluminium or cement, the practical shortlist is a CBAM-specific tool such as The Sustainability Cloud or a carbon platform with product-level footprints such as Climes. The deciding question: will you ever need the same data for BRSR Core, SBTi or a buyer's ISO 14067 request? If yes, a single-framework tool means buying twice.
