About Mangue

The ESG data foundation your company needs to report with confidence.

Operational data becomes defensible compliance. No parallel spreadsheets, no rework, no window dressing.

Method

GHG Protocol, CSRD, IFRS S2, CDP, GRI, SASB. More than 20 frameworks. Every factor with a source, every figure with a version, every calculation auditable.

Technology

A modular SaaS platform that cuts inventory time by 90%. A calculation engine with 60,000+ factors, ERP integration, ready-made dashboards and Crab.AI.

Team

Specialists in sustainability, technology and data management. Consulting on GHG inventory, materiality, LCA, decarbonization and reporting.

What we believe

Four non-negotiable convictions.

No greenwashing

If it cannot be audited, it does not go in the report.

Defensible data

An estimate without a source is a guess. A guess does not survive verification.

Speed matters

An inventory that takes months decides nothing. One that takes weeks does.

Brazil first

MCTI factors, local industrial reality, Brazilian standards.

How we think

Our principles guide every calculation.

Auditable by default.

Every entry is recorded and cannot be erased. It always traces back to the source.

Public calculation record.

Open calculation memo · traceable factors and sources. Clients can bring in an external auditor on request.

Versioned.

When the base year changes, we recalculate with the history in the open. Every factor carries its source and year.

Multilingual.

Portuguese, English, Spanish and French. Units and regulation localized.

Multi-framework.

One base. 20+ outputs. CSRD, GRI, IFRS S2, CDP and more.

Open.

Export to CSV, JSON and XBRL. The data is yours, always.

Track record

Built with people who refuse shortcuts.

Client voice

The number that matters when you sell a service.

They measured, they calculated, they defended it in the audit. And they came back to say so. That is what separates a platform in use from a product that stayed in the proposal PDF.
