Sustainability and ESG software development

ESG reporting has moved from voluntary to mandatory. CSRD covers 50,000+ EU companies. SEC climate disclosure rules affect US public companies. Organisations that built manual spreadsheet-based ESG processes are now facing regulatory deadlines with infrastructure that can't scale to the reporting depth required.

  • ESG data collection from operational systems, energy, water, waste, fleet, facilities

  • Carbon accounting covering Scope 1, 2, and 3 emissions with audit-ready evidence

  • Framework-aligned reporting for GRI, SASB, TCFD, CSRD, and custom disclosure requirements

  • Supply chain sustainability data collection from tier-1 and tier-2 suppliers

Recognition

Sound familiar?

  • ESG data scattered across spreadsheets, energy bills, HR systems, and supplier emails, with no single source of truth that survives a regulator's data quality challenge?

  • Sustainability team spending 80% of their time collecting data rather than acting on it because there's no automated data pipeline from the systems where emissions and resource use actually occur?

In short

RaftLabs builds custom sustainability and ESG software for organisations managing ESG data collection, carbon accounting, regulatory reporting, and supply chain sustainability. We develop ESG data platforms that aggregate operational data from multiple source systems, map it to GRI, SASB, TCFD, and CSRD disclosure requirements, and produce the audit-ready evidence regulators and external assurance providers require. Most ESG software development projects deliver in 10 to 16 weeks at a fixed cost.

01 Diagnosis

Problems we solve in sustainability and ESG

  1. 01
    Problem

    Sustainability team spending 80% of each reporting cycle collecting data instead of acting on it

    Solution

    When ESG data lives across energy management systems, facilities spreadsheets, fleet telematics, HR exports, and supplier emails, data collection becomes a manual project that starts months before each reporting deadline. According to Deloitte's 2024 Sustainability Action Report, 57% of executives cite data quality as their top ESG reporting challenge, and 88% rank it among their top three challenges. The cost is the sustainability work that doesn't happen: reduction programmes, supplier engagement, target-setting. The team has no capacity left after assembling the data. Automated pipelines from source systems into a single verified data store return that capacity to the team.

  2. 02
    Problem

    ESG disclosures that don't survive detailed audit scrutiny

    Solution

    External assurance providers and regulators don't accept ESG figures without a traceable methodology. They need to know which source system produced the data, which emission factor was applied, and when the calculation ran. Figures assembled manually from spreadsheets can't provide that trail. A system with calculation methodology documentation and data lineage from source to disclosed figure is what audit-ready ESG reporting requires.

  3. 03
    Problem

    CSRD deadline approaching with a data collection process that is entirely manual

    Solution

    CSRD under ESRS requires disclosure at a granularity that manual processes can't sustain. It demands specific data points across environment, social, and governance topics, with the evidence base auditors need. Organisations that built lightweight ESG processes for voluntary reporting are facing mandatory deadlines with infrastructure that was never designed for regulatory compliance. The gap between voluntary and mandatory reporting depth requires platform investment, not more spreadsheet columns.

  4. 04
    Problem

    Scope 3 emissions reported using spend-based estimates because no structured supplier data process exists

    Solution

    Spend-based Scope 3 estimates are acceptable as a starting point. Regulators and institutional investors are increasingly demanding primary supplier data for material Scope 3 categories. Without a structured supplier data collection portal and a systematic engagement process, Scope 3 accuracy can't improve year on year. Organisations with significant supply chain emissions face growing investor pressure on this point, and spend-based estimates won't hold up indefinitely.

02 What we ship

ESG software we ship

  1. ESG data collection and aggregation

    Automated data pipelines from the operational systems where ESG data originates: energy management platforms, building management systems, fleet telematics, HR systems, waste management portals, and utility providers. API integrations and scheduled data pulls replace manual spreadsheet exports. Data normalisation handles different units, reporting periods, and organisational boundaries. The result is a single verified ESG data store updated on a schedule your reporting cycle can rely on, not assembled from scratch each quarter by your sustainability team.

  2. Carbon accounting software

    GHG Protocol-compliant carbon accounting covering Scope 1 direct emissions, Scope 2 purchased energy emissions using both location-based and market-based methods, and Scope 3 value chain emissions across all relevant categories. Emission factor databases from IPCC, EPA, DEFRA, and IEA are applied to activity data from your operations. Supplier emissions data collection and spend-based estimation cover Scope 3 categories where primary data is unavailable. Calculation methodology documentation and an audit trail back every emissions figure your reports disclose.

  3. Regulatory and framework reporting

    Reporting outputs mapped to the specific disclosure requirements of GRI Standards, SASB industry standards, TCFD recommendations, and CSRD European Sustainability Reporting Standards. A framework-agnostic data model maps collected ESG data to multiple frameworks simultaneously, so you're not running separate data collection processes for each standard you report to. Disclosure document generation includes data lineage: each disclosed figure traces back to the source data and calculation methodology. Reporting that satisfies your auditors rather than triggering data quality questions.

  4. Supply chain sustainability

    Supplier sustainability assessment portals collect environmental performance data, labour practices disclosures, certification evidence, and Scope 3 emissions data from tier-1 and tier-2 suppliers. Structured questionnaires align to your supply chain reporting obligations. Automated follow-up workflows handle incomplete submissions. Data quality validation flags implausible supplier responses before they enter your reported figures. Supplier performance scoring and monitoring over time means your supply chain sustainability position is tracked rather than assessed from scratch each year.

  5. ESG stakeholder disclosure portals

    Investor-facing and public ESG disclosure portals present your sustainability data clearly, with the methodology transparency institutional investors and rating agencies require. ESG data export supports formats compatible with CDP, EcoVadis, and investor ESG questionnaires. Controlled access for external stakeholders, including investors, customers, and lenders, means they can access specific ESG data without entering your full internal platform. Versioned disclosure records keep prior-year reports accessible and preserve the data behind them.

  6. ESG analytics and performance tracking

    ESG performance dashboards track your sustainability metrics against set targets: carbon reduction targets, renewable energy percentage, supplier sustainability scores, and diversity metrics over time. Year-on-year trend analysis includes normalisation for business activity changes, using emissions intensity rather than absolute figures when revenue or production changes. Scenario modelling supports carbon reduction pathway planning. Early warning alerts fire when metrics trend away from targets with enough lead time to intervene before the reporting period closes.

03 How we work

How we build ESG software

  1. 01

    Discovery

    We map your current ESG data sources against your reporting framework obligations and your next disclosure deadline. The session covers which systems hold energy, water, waste, fleet, HR, and supplier data. It includes your sustainability team, IT, and finance to confirm which data integrations are feasible and which gaps require a supplier engagement programme.

  2. 02

    Architecture

    We design the ESG data model: a framework-agnostic schema that maps collected data to GRI, SASB, TCFD, CSRD, and any internal reporting requirements simultaneously. The calculation methodology for each metric, including emission factors, unit conversions, and boundary definitions, is documented before build so your assurance provider can review the approach.

  3. 03

    Build

    Development runs in two-week sprints, starting with the highest-priority data integrations and framework mappings. The Scope 1 and 2 carbon accounting module is built and validated before Scope 3 supplier collection is added. Framework reporting outputs are built alongside the data pipelines so your team can see draft disclosures as data flows through the system.

  4. 04

    Launch and support

    The first reporting cycle after go-live runs with both the new platform and your existing process in parallel, so your team can verify the outputs before relying on them for a regulatory submission. Post-launch support covers new data source integrations as your reporting scope expands, emission factor database updates, and configuration changes when regulatory requirements change.

08 Questions

Frequently asked questions

We build against GRI Standards, SASB industry-specific standards, TCFD recommendations, and the European Sustainability Reporting Standards (ESRS) under CSRD. The data model we design is framework-agnostic: ESG data is collected and stored once, then mapped to the specific disclosure requirements of each framework you report to. This means adding a new framework doesn't require rebuilding your data collection process. We also build against custom internal reporting requirements for organisations that have proprietary ESG metrics beyond the standard framework disclosures.

Scope 3 emissions are the hardest to collect because the data originates outside your organisation. We use a tiered approach: primary data collection from suppliers via a structured portal for your most significant supply chain relationships; spend-based estimation using industry emission factors for the long tail of suppliers where primary data collection isn't practical; and supplier assessments that capture the information needed to improve estimation accuracy over time. Data quality flags distinguish primary data from estimates in your reported figures so your methodology is transparent to auditors.

Those platforms are good products for organisations whose ESG reporting needs match the standard configuration they offer. Custom makes sense when your situation doesn't fit the standard: complex operational data from proprietary source systems that the platforms don't integrate with; supply chain data collection requirements specific to your industry or customer obligations; ESG data that needs to feed into existing internal systems rather than sit in a standalone platform; or regulatory requirements that are more specific than the frameworks these platforms cover. We assess this honestly during discovery. If a commercial platform would serve you better, we'll say so.

A focused ESG software project covering one framework, one primary data source, and regulatory reporting output typically costs $30,000 to $80,000. A full ESG platform covering multiple data source integrations, Scope 1, 2, and 3 carbon accounting, multi-framework reporting, a supplier data collection portal, and a stakeholder disclosure portal runs $80,000 to $200,000. The range is wide because scope varies significantly. We fix the cost before development starts after a scoping conversation that defines exactly what is included.
