Emitwise no longer exists as a standalone product. Green Project Technologies acquired the platform in July 2025, and its technology now sits inside Green Project’s supply chain and product carbon footprint tools. Teams that ran carbon accounting on Emitwise are choosing between following the platform into Green Project or moving somewhere else. This guide compares five alternatives on the criteria that decide that switch: Scope 1, 2, and 3 coverage, supplier data collection, framework alignment, and whether the platform holds up under external assurance.
A forced migration is also the cheapest moment to ask a wider question. Carbon accounting is one part of a program that now answers to CSRD, CDP, and ISSB from the same underlying data. A tool that counts carbon alone leaves the rest of that reporting in spreadsheets, which is why more teams are consolidating carbon and broader ESG data on one platform.
The five platforms below all handle supply chain decarbonization and regulatory-grade reporting. They differ in how much of the wider sustainability data problem they take on.

5 Emitwise alternatives for ESG and carbon management
1. Pulsora
Pulsora is an end-to-end sustainability management platform that combines ESG and carbon management (Scope 1, 2, and 3) in one tool. They offer strong support for regulatory frameworks like CSRD, CDP, ISSB, and SBTi.
Noteworthy features:
- Purpose-built for auditor assurance
- Flexible to match evolving disclosure requirements
- Modern, powerful interface that caters to agentic AI and LLM implementation
2. Sweep
Sweep is a visual-first carbon and ESG management platform with collaboration tools that help global teams track emissions across business units and suppliers.
Noteworthy features:
- Visual dashboards and scenario planning
- Built-in collaboration for task and team workflows
- Portfolio and subsidiary-level emissions management
3. Workiva (formerly) Sustain.Life
Workiva’s carbon solutions (formerly Sustain.Life) are designed for carbon measurement, ESG reporting, and internal training, but for specific industries like finance. Because they acquired Sustain.Life as their carbon offering, it’s still bolted on – not integrated into the solution and purpose-built like Pulsora.
Noteworthy features:
- Unified reporting workflows for ESG and financial disclosures
- Support for CSRD, California climate rulings, and other regulations
- Enhanced auditability and collaboration across departments
4. Osapiens
Osapiens offers solutions for disclosures and reporting, risk management, and traceability across an organization’s full sustainability program. They’re EU-based and work primarily with customers based there, though they do have global reach.
Noteworthy features:
- Sensor data and real-time transmission
- Osapiens HUB for end-to-end management
- Support for EU taxonomy, CSRD, GRI, SASB, etc.
5. Greenly
Greenly is another EU-based all-in-one platform that offers both a suite of products to measure, execute, and comply with carbon and ESG standards. Because they also support small businesses and mid-market organizations, their full solution may not be robust enough to support enterprise-level companies.
Noteworthy features:
- AI-powered anomaly detection
- Support for 300,000 emissions factors
- Scope 3 accuracy
Why purpose-built matters: Auditor assurance and adaptability
As sustainability reporting becomes more regulated and complex, companies need more than just a carbon calculator or ESG dashboard – they need a platform purpose-built for assurance from the ground up.
Solutions designed with auditor oversight in mind ensure traceability, data integrity, and version control across every metric and methodology.
Equally important is the ability to adapt to change. Disclosure requirements are evolving fast, from voluntary frameworks like CDP and the SBTi to mandatory rules under CSRD and beyond.
At the same time, companies are maturing their sustainability programs, with new teams, roles, and cross-functional workflows. A truly future-ready platform must flex with both: shifting standards and shifting organizational structures.
Without this foundation, companies risk fragmented data, duplicated effort, and compliance gaps when it matters most.
Why Pulsora is the best Emitwise alternative
For Emitwise customers seeking more than a one-size-fits-all transition, Pulsora offers a truly purpose-built alternative.
Unlike platforms that focus solely on carbon or ESG in isolation, Pulsora unifies both into a single, enterprise-grade system that’s purpose-built for auditor assurance, regulatory compliance, and organizational scale.
Whether you're navigating decarbonization complexity, preparing for CSRD disclosures, or evolving your sustainability operations across global teams, Pulsora delivers the flexibility, depth, and control needed to lead with confidence.
If you're ready for a solution that grows with your strategy, not against it, Pulsora is the partner to trust. See our platform in action by booking a personalized demo.
