Plan A
Plan A is a Berlin-born carbon accounting and decarbonization platform, founded in 2017 and acquired by Diginex in January 2026. Built for European enterprises navigating CSRD obligations alongside active emissions reduction, it combines TÜV Rheinland-certified carbon accounting with science-based decarbonization planning in a single workflow — with an explicit position that reduction must come before reporting.
Sweep
Carbon and ESG data governance platform engineered for multi-entity corporate groups. Sweep's founding insight is that most organizations know how to calculate their emissions — they just cannot get the data from their subsidiaries in a state that makes calculation meaningful. The platform governs collection, enforces methodology, and produces the audit lineage that CSRD-grade assurance requires.

European mid-market to large enterprises at Stage 3 maturity — organizations with a CSRD obligation on the horizon, a commitment to SBTi, and a need to move from compliance baseline to active decarbonization plan within a single platform.
Multinational corporate groups and listed companies with 10 or more subsidiary entities that must consolidate carbon and ESG data across complex organizational structures — where the primary obstacle to CSRD compliance is not knowing how to calculate emissions, but not being able to get clean, governed, auditable data out of 25 different business units in time to produce a figure an assurance provider will not challenge.

Key features
- TÜV Rheinland-Certified Carbon Accounting — GHG Protocol and SBTi Aligned Plan A's carbon accounting methodology is certified by TÜV Rheinland and aligned with the GHG Protocol Corporate Standard and SBTi criteria. The platform covers Scope 1, 2, and 3 emissions across all 15 categories using AI-assisted data mapping, automated anomaly detection, and customizable calculation methods developed in collaboration with a Scientific Advisory Board. The certification is operationally significant for European enterprises: it provides documented third-party confirmation of methodology alignment that can be presented to auditors, CSRD reporting reviewers, and SBTi technical staff without requiring the organization to reconstruct its methodology rationale from scratch.
- Decarbonization Planning and ROI Scenario Modeling Plan A is built on the premise that carbon accounting exists to produce a reduction plan, not merely a disclosure. The platform includes science-based decarbonization scenario modeling — allowing organizations to test the emissions impact and financial ROI of specific reduction initiatives before committing resources. Scenarios can be modeled at Scope level, by business unit, by geography, or by supplier category. The output is a structured reduction roadmap aligned with SBTi pathways, with progress tracking built into the same platform as the measurement. For organizations that need to demonstrate a credible decarbonization trajectory — to a board, a regulator, or an SBTi reviewer — the scenario tool connects the baseline footprint to a forward-looking strategy in a way that static reporting cannot.
- CSRD-Aligned Reporting and ESG Framework Integration Plan A's reporting module supports CSRD disclosure preparation with pre-structured ESRS E1 outputs covering GHG emissions, transition risk indicators, and climate targets. The platform is SOC 2 and GDPR compliant, with an audit trail maintained across data ingestion, calculation, and output generation. Through the Diginex acquisition (completed January 15, 2026), Plan A's carbon accounting capability is being integrated with Diginex's broader ESG reporting infrastructure spanning 19 global frameworks — extending the platform's reach beyond carbon-only disclosure toward a more complete CSRD data point coverage. This integration is in progress as of mid-2026; buyers evaluating the combined platform should confirm the current state of ESRS social and governance coverage with the vendor directly.
- Multi-entity consolidation architecture — a parent-subsidiary data model that preserves entity-level granularity while producing group-level rollup with full traceability. Designed around the organizational reality that a sustainability director in Paris cannot compel a plant manager in Seoul to submit clean data on deadline — and builds the workflow infrastructure that makes it happen anyway.
- Supplier Scope 3 engagement engine — structured primary data requests distributed to suppliers through a managed portal, with completion tracking, automated follow-up, and direct ingestion of supplier-provided emission factors into the group inventory. The gap between a Scope 3 figure built on EEIO spend proxies and one built on primary supplier data is not a rounding error. It is the difference between a disclosure an assurance provider accepts and one they qualify.
- Native audit lineage layer — an immutable record linking every disclosed figure to its source entity, data owner, input method, emission factor version, and submission timestamp. Under CSRD limited assurance — and increasingly under reasonable assurance — the assurance provider is not checking your arithmetic. They are checking whether your governance process can be documented and followed end to end. Sweep makes that documentation automatic rather than retrospective.
Pros
- Plan A's explicit positioning — that decarbonization must come before disclosure — is a philosophical stance with operational consequences. The platform is built so that the measurement leads directly to a reduction roadmap, and the reduction roadmap leads to a compliant disclosure, in a single workflow. For European mid-market organizations that need to demonstrate a credible SBTi pathway alongside their CSRD reporting obligations, this sequence is built into the product rather than requiring a separate strategy engagement. The TÜV Rheinland certification of the methodology provides the documentation anchor that makes the resulting footprint defensible in both an SBTi technical review and a CSRD assurance engagement.
- The platform's accessibility for organizations without a large sustainability team is a practical differentiator at the mid-market level. AI-assisted data mapping, automated anomaly detection, and ready-to-use calculation methods reduce the time and specialist knowledge required to build a first Scope 3 inventory. The AI-driven data processing retains organizational context — memorizing naming conventions and custom data structures across reporting cycles — so the second year of carbon accounting takes materially less time than the first. For organizations that cannot justify a full-time sustainability data function but face a CSRD reporting obligation for FY2027 data, this reduction in operational friction is financially material.
- The Diginex acquisition opens a strategic dimension that Plan A as a standalone platform could not offer: integration with ESG reporting coverage across 19 global frameworks, supply chain transparency infrastructure, and AI-driven analytics from Matter DK. For Plan A's existing customer base — which includes BMW, Deutsche Bank, Visa, Chloé, and Trivago — the combined platform trajectory points toward an end-to-end solution that links regulatory compliance, value chain emissions, and decarbonization strategy. The integration is a work in progress, and buyers should evaluate the current state carefully. But the strategic direction addresses the fragmentation problem that carbon-only platforms structurally cannot solve alone.
- Most carbon accounting failures at group level are coordination failures, not calculation failures. Sweep is the only platform in this category architected specifically around that insight — and the multi-entity data model is genuinely different from carbon calculators that added a "group" feature as an afterthought. Organizations with 20 or more entities that have tried to consolidate via spreadsheet will recognize immediately what problem Sweep was built to solve.
- The Scope 3 supplier portal is among the most operationally significant capabilities in the platform. Spend-based Scope 3 estimation is fast, cheap, and increasingly inadequate — SBTi validation, CDP quality ratings, and CSRD assurance providers are all applying more scrutiny to Category 1 methodology. A managed portal that industrializes primary data collection and tracks supplier response rates year-on-year addresses this gap in a way that a general-purpose carbon tool cannot.
- Audit lineage that is generated automatically, rather than reconstructed under deadline pressure, is the practical difference between a first CSRD assurance engagement that goes smoothly and one that does not. The platform logs provenance continuously throughout the reporting cycle. When the assurance team arrives, they review a record — they do not trigger a documentation exercise.
Cons
- The Diginex acquisition, completed January 15, 2026, introduces a transition period whose duration and impact on product stability are genuinely uncertain. Integration of two distinct technology stacks — Plan A's carbon accounting engine and Diginex's ESG reporting infrastructure — is a complex technical process. The platform's roadmap will be shaped by the priorities of the combined entity rather than by Plan A's standalone strategy. Organizations evaluating Plan A in mid-2026 should ask explicitly about product roadmap commitments, data migration guarantees, and the contractual terms that apply if the integration changes the platform materially. This is not a reason to avoid the platform; it is a reason to evaluate with the same diligence applied to any software that has recently changed ownership.
- Plan A's Scope 3 depth and enterprise scalability are competitive for the European mid-market but less developed than the specialist tools at the enterprise tier. Organizations with highly complex global supply chains, a Scope 3 Category 1 inventory spanning thousands of suppliers in multiple geographies, or significant financed emissions (PCAF Category 15) will encounter the ceiling of Plan A's methodology before the ceiling of their own data complexity. <a href="/ai_tool/watershed/">Watershed</a> is purpose-built for the former; <a href="/ai_tool/persefoni/">Persefoni</a> is purpose-built for the latter. Plan A is not trying to compete with either on those dimensions — it is not positioned there by design — but buyers evaluating across the full market should calibrate expectations accordingly.
- Plan A's pricing is enterprise-negotiated and not publicly disclosed, which places it in the same evaluation challenge as Watershed and Persefoni. Unlike Normative, which offers two named tiers (Essential and Premium), Plan A does not publish a tier structure. For mid-market organizations where budget predictability is a constraint, the absence of published pricing creates friction at the evaluation stage. The venture funding history — approximately $27 million raised between 2021 and 2023 — and the Diginex acquisition at approximately €55 million suggest a platform that is priced for the organizations that can commit at enterprise contract level, not for teams evaluating on a trial or annual-renewal basis.
- The organizational complexity that makes Sweep valuable is also the precondition for its value. A company with one legal entity, straightforward energy and travel data, and no supplier engagement program will pay enterprise pricing for multi-entity consolidation infrastructure it cannot use. For that profile, Normative, Watershed, or Persefoni deliver better value per unit of effort and cost.
- Implementation timeline is driven by organizational readiness, not platform configuration. The platform can be technically configured in weeks. Getting 25 subsidiary data owners — finance managers, operations leads, facility administrators who have other jobs and no sustainability background — identified, briefed, trained, and actively submitting quality data to a deadline takes months of structured change management. This is not a software caveat. It is the nature of the problem the software is solving. But buyers who treat it as a software project will be surprised.
- Sweep governs and consolidates. It does not build the decarbonization program that acts on what the data reveals. Organizations that have consolidated their ESG data and now need to manage reduction initiatives, track intervention progress, and connect emissions to budget allocation should evaluate Watershed for the program management layer, or SINAI Technologies for the marginal abatement analysis that informs where to invest.
