AWS-native emissions reporting with audit trails

Onye Dike
Updated by Onye Dike on February 20th, 2026
FlexZero is a carbon management and disclosure platform sold via AWS Marketplace for teams that need auditable Scope 1–3 inventories and repeatable reporting cycles. It turns operational data into activity-level emissions, then rolls results up to business-unit and company views for benchmarking, forecasting, and target tracking. Automated scope and method assignments support consistent categorization. A no-code calculation engine lets sustainability and finance users adjust equations and emission factors (including USEPA options) without rebuilding data pipelines. FlexZero fits organizations that already run data on AWS and want CDP/TCFD-ready outputs, dashboards, and traceability from ingestion to reports at scale.

Core Features

FlexZero frames carbon accounting as a configurable data workflow: it ingests enterprise activity data, applies emissions-factor-based calculations, and keeps results traceable back to source records. The platform emphasizes flexible calculation methods and a no-code approach so reporting teams can adapt inventories as requirements change. Some of its main features are:

  • Activity-level calculation and rollups: Converts incoming operational data into activity-level emissions and aggregates to business-unit/company views.

  • No-code calculation engine: Builds transformations and equations with a no-code UI, supporting custom and pre-built logic.

  • Scope and method assignments: Guides data-feed setup with automated scope/method assignments based on industry standards.

  • Standards-based factors and templates: Includes industry-standard emission factors (examples listed include USEPA) and reporting templates.

  • Disclosure reporting outputs: Produces reports positioned around frameworks such as CDP and TCFD, with automated generation/delivery in the AWS listing.

  • Auditability and benchmarking: Maintains audit trails from ingestion to reporting and supports benchmarking (described as versioned/transparent in the AWS listing).

Closing Insights

FlexZero was founded by David Johnsen and Ravi Raghunathan after work on sustainability solutions on AWS. Johnsen previously served in AWS Professional Services as a sustainability application architect and has a PhD in environmental engineering. FlexZero positions carbon accounting as a configurable data workflow: users define incoming datasets, calculation methods, and reporting outputs, with audit trails and versioned benchmarks.

AWS has profiled FlexZero’s use of Amazon Bedrock to power a chat-style interface for emissions questions, and Amazon Textract to pull structured data from documents. A named customer is Climate Pledge Arena, which transitioned its sustainability data management to FlexZero and used it to convert utility bills into actionable data.

For compliance-driven teams, FlexZero supports disclosure-style reporting such as CDP and TCFD, and California's SB 253. Recent ecosystem activity includes an AWS Marketplace solution pairing FlexZero with SS&C Blue Prism services for automated ESG data ingestion.

FlexZero is sold via AWS Marketplace with the listing showing a $4,000/month 1-month contract option (other terms available).
