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. The organisations that built manual spreadsheet-based ESG processes are now facing regulatory deadlines with infrastructure that cannot scale to the reporting depth required.
We build the software that collects ESG data from your operations, supply chain, and facilities -- organises it by framework (GRI, SASB, TCFD, CSRD), tracks it over time, and produces the disclosures your auditors and regulators need.
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
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.

ESG reporting requires infrastructure, not just effort
ESG reporting has a data collection problem. The emissions data lives in energy management systems. Waste data lives with facilities teams. Supplier sustainability data lives in emails and ad-hoc spreadsheets. HR data for social metrics lives in your HRIS. None of it connects. The sustainability team manually assembles this each reporting cycle -- a process that takes months and produces results that don't survive detailed audit scrutiny.
The organisations managing ESG reporting at scale have built data infrastructure: automated pipelines from source systems into a single verified data store, mapped against the disclosure frameworks they report to, with the audit trail that external assurance providers require. That infrastructure is what we build.
Problems we solve in sustainability and ESG
- 01
Sustainability team spending 80% of each reporting cycle collecting data instead of acting on it
When ESG data lives across energy management systems, facilities spreadsheets, fleet telematics, HR exports, and supplier emails, data collection is a manual project that starts months before each reporting deadline. The cost is the sustainability work that doesn't happen -- reduction programmes, supplier engagement, target-setting -- because 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.
- 02
ESG disclosures that don't survive detailed audit scrutiny because the data trail back to source is missing
External assurance providers and regulators do not accept ESG figures without a traceable methodology -- which source system produced the data, which emission factor was applied, and when the calculation was performed. Figures assembled manually from spreadsheets cannot provide that trail. A system with calculation methodology documentation and data lineage from source to disclosed figure is what audit-ready ESG reporting requires.
- 03
CSRD deadline approaching with a data collection process that is entirely manual and cannot scale to ESRS depth
CSRD under ESRS requires disclosure at a granularity that manual processes cannot sustain -- 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.
- 04
Scope 3 emissions reported using spend-based estimates because no structured supplier data process exists
Spend-based Scope 3 estimates are acceptable as a starting point, but 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 cannot improve year on year. Organisations with significant supply chain emissions face growing investor pressure on this point, and spend-based estimates will not hold up indefinitely.
What we build
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 across different units, reporting periods, and organisational boundaries. 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.
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 applied to activity data from your operations. Supplier emissions data collection and spend-based estimation for Scope 3 categories where primary data is unavailable. Calculation methodology documentation and audit trail for each emissions figure your reports disclose.
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 that 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 with data lineage: each disclosed figure traceable back to the source data and calculation methodology. Reporting that satisfies your auditors rather than triggering data quality questions.
Supply chain sustainability
Supplier sustainability assessment portals that collect environmental performance data, labour practices disclosures, certification evidence, and scope 3 emissions data from tier-1 and tier-2 suppliers. Structured questionnaires aligned to your supply chain reporting obligations. Automated follow-up workflows for incomplete submissions. Data quality validation to flag implausible supplier responses before they enter your reported figures. Supplier performance scoring and monitoring over time so your supply chain sustainability position is tracked rather than assessed from scratch each year.
ESG stakeholder disclosure portals
Investor-facing and public ESG disclosure portals that present your sustainability data clearly, with the methodology transparency institutional investors and rating agencies require. ESG data export in formats compatible with CDP, EcoVadis, and investor ESG questionnaires. Controlled access for external stakeholders -- investors, customers, and lenders -- who need specific ESG data without accessing your full internal platform. Versioned disclosure records so prior-year reports remain accessible and the data behind them is preserved.
ESG analytics and performance tracking
ESG performance dashboards that 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 with normalisation for business activity changes (emissions intensity rather than absolute figures when revenue or production changes). Scenario modelling for carbon reduction pathway planning. Early warning alerts when metrics are trending away from targets with enough lead time to intervene before the reporting period closes.
How we work with sustainability and ESG clients
- 01
Discovery
We map your current ESG data sources -- which systems hold energy, water, waste, fleet, HR, and supplier data -- against your reporting framework obligations and your next disclosure deadline. This session includes your sustainability team, IT, and finance to confirm which data integrations are feasible and which gaps require a supplier engagement programme.
- 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 -- emission factors, unit conversions, boundary definitions -- is documented before build so your assurance provider can review the approach.
- 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.
- 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.
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 data collection 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 -- one framework, one primary data source, 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.
