Case Study

Introduction

Persefoni is a carbon accounting and climate disclosure platform that helps enterprises and financial institutions measure, manage, and disclose their carbon footprints in compliance with global standards. Designed for CFOs, ESG managers, and sustainability teams, Persefoni turns raw operational data into audit-ready GHG reports aligned with frameworks like the SEC Climate Rule, TCFD, and GRI.

To achieve this level of reporting precision and automation, Persefoni engaged Top Remotely to build and scale its enterprise-grade carbon intelligence platform. Top Remotely led the technical development across backend automation, regulatory template engines, and integrations with finance and HR systems, ensuring the platform delivered both compliance and usability for non-expert users.

Often referred to as a “carbon ERP,” Persefoni brings financial-grade rigor and transparency to sustainability reporting—empowered by Top Remotely’s architecture that prioritizes traceability, scalability, and secure automation.

Challenges

Organizations managing ESG and sustainability efforts faced a range of obstacles:

• Manually compiling GHG data from multiple, disconnected sources.

• Limited expertise in evolving climate disclosure regulations.

• Lack of audit-ready carbon data that satisfies investor scrutiny.

• Risk of greenwashing accusations due to inconsistent reporting.

Top Remotely worked closely with Persefoni to eliminate these barriers by building automation workflows and audit-ready frameworks designed for real-time financial and ESG alignment.

Objectives

In partnership with Persefoni’s ESG experts, Top Remotely was tasked with translating complex sustainability goals into accessible, secure software systems, specifically to:

• Automate Scope 1, 2, and 3 carbon accounting at the enterprise level.

• Ensure compliance with emerging global disclosure mandates (e.g., SEC, ISSB, CDP).

• Improve internal confidence and external credibility in ESG data.

• Integrate carbon performance into core financial decision-making tools.

Top Remotely’s goal was to simplify compliance while enabling strategic carbon management inside CFO workflows.

Solutions

Top Remotely helped architect and implement Persefoni’s modular SaaS platform, focusing on core features that could scale across sectors:

1. Automated Carbon Accounting
   Translated operational and financial data into accurate emissions metrics using embedded methodologies (GHG Protocol, ISO 14064). Engineered auto-tagging logic and classification hierarchies to map emissions accurately across spend categories.
2. Climate Disclosure Templates
   Built dynamic, standards-aligned disclosure templates for CDP, TCFD, and SEC Climate Rule. Included smart validations, pre-filled sections, and compliance status indicators.
3. Scenario Modeling
   Developed tools to simulate emissions trajectories and measure impact of carbon-reduction initiatives under various strategic assumptions.
4. Governance & Audit Tools
   Created role-based permissioning, version history logs, and auditor portals—allowing for secure collaboration and third-party review.
5. Integrations
   Deployed scalable REST APIs connecting with systems like Oracle, Workday, SAP, and Coupa, enabling seamless data ingestion from financial, HR, and procurement systems.

Deployment Process

Top Remotely led the platform deployment across multiple enterprises, following a structured and collaborative approach:

1. Data Integration
   Integrated Persefoni with clients’ general ledgers, procurement platforms, and HR databases—enabling centralized data mapping and ingestion.
2. Emissions Mapping
   Designed emissions categorization workflows to auto-assign scopes and categories to financial transactions based on spend type, geography, and vendor classification.
3. Stakeholder Alignment
   Built interactive dashboards and collaboration tools to align sustainability, compliance, and finance teams on unified carbon data.
4. Review & Sign-Off
   Developed audit-ready reporting workflows with access control, revision tracking, and export capabilities for third-party assurance.

Results

Persefoni’s climate disclosure platform—architected and engineered in collaboration with Top Remotely’s deep ESG-tech team—achieved powerful outcomes for enterprise clients:

• 55% reduction in time spent on GHG reporting across sustainability and finance departments.

• 100% alignment with SEC Climate Rule draft achieved within just two months of onboarding.

• Successful first CDP submission with a B score, improving investor transparency and stakeholder trust.

• 9% Scope 2 emissions reduction driven by internal strategy changes prompted by platform insights.

Top Remotely’s engineering enabled Persefoni to combine climate intelligence with financial discipline—empowering strategic action, not just reporting.

Technology Stack

• Backend: Python (Django), PostgreSQL
  
• Data Analytics: Apache Airflow, Pandas, SciPy
  
• Frontend: React.js, Material UI
  
• Cloud Infrastructure: Microsoft Azure (compliant with SOC 2, ISO 27001, and GDPR)
  
• Integrations: REST APIs for Oracle, Workday, Coupa, SAP

Persefoni excels at demystifying carbon disclosure and bringing enterprise-level discipline to sustainability metrics. Top Remotely played a central role in making this possible—developing secure data pipelines, disclosure modules, and enterprise integrations that turned complex GHG requirements into a user-friendly, audit-grade platform.

This case illustrates how digital carbon intelligence, built with the right technical foundation, becomes not just a compliance requirement—but a strategic lever for informed growth and investor alignment. Persefoni and Top Remotely together prove that climate reporting can be transparent, accurate, and actionable at scale.
