Japanese Energy Company Cuts GHG Reporting Time by 60%

HSE teams of large energy companies are under constant pressure – balancing compliance deadlines, growing ESG demands, and the daily reality of tracking emissions across complex facilities. In this environment, manual spreadsheets and fragmented data flows create risk, waste time, and leave people scrambling during audits.

To address this, a leading Japanese energy company (natural gas) piloted UNLSH, our no-code Any-to-Any data platform, to streamline its greenhouse gas (GHG) and energy reporting workflows. They chose the midstream segment of their integrated operations for this project.

The results were clear:

  • ~60% reduction in manual reporting workload – 15-20 hours saved per week across the team
  • Audit-ready, traceable data pipelines
  • Full alignment with upcoming disclosure mandates (ISSB, GX League)
  • No-code control for HSE engineers – CO₂ factors and thresholds updated without IT support
60% Less Reporting Effort. Full Audit Readiness. Reduced IT Dependencies.

Background

The client, a Japanese energy major, was facing increased pressure from both regulators and internal stakeholders to:

  • Improve auditability of GHG and energy disclosures
  • Reduce manual data handling and spreadsheet complexity
  • Deliver timely, accurate emissions data for ESG reporting and internal performance reviews

The HSE Team’s Challenge:

  • Data was being manually transcribed from DCS, SCADA, and PI Systems
  • Energy and production balances were calculated in disconnected Excel files
  • Visibility into daily CO₂ emissions was non-existent or lagging

Objective

UNLSH was piloted to assess whether it could serve as a platform to:

  • Automate CO₂ and energy data processing
  • Provide full traceability for all inputs, calculations, and overrides
  • Enable HSE teams to manage reporting logic independently – with minimal IT dependency

Solution

The pilot replicated real HSE workflows from one of the most complex production sites: It covered:

  • Ingestion of high-frequency time-series data (1-minute resolution) from AVEVA OSISoft PI
  • Structured capture of manual inputs (e.g., tank levels, vendor-supplied power)
  • Multi-stage processing:
    • Fuel and power balance calculations
    • Daily CO2 estimation per production train
    • Generaion of daily/monthly GHG and energy reports

The pilot project was completed in ~7 weeks, including configuration, validation, and user training. All logic was implemented through a no-code interface, with no changes to existing plant systems. Given UNLSH's scalable architecture, additional site rollouts will take significantly less time per site.

UNLSH is a highly secure data platform built for manufacturing environments. It brings together data from any industrial source and structures the data in a way that reflects real operational context, all without writing code. It meets the data security and governance standards of global manufacturing leaders.

Outcome

1. 60% Reduction in Reporting Workload: Manual reconciliation and Excel updates were eliminated. Daily/monthly reports are now auto-generated from live data sources. This represents approximately 15-20 hours per week of manual work eliminated across the HSE team.

“With UNLSH, we have cut most of the manual work from our GHG and ESG reporting. What used to take hours or days before now happens automatically. We know the numbers are reliable every time.”

2. Full Transparency and Auditability: Every input, formula, and manual override is timestamped and logged – creating a compliant, inspection-ready trail for regulators and internal audits.

“Before UNLSH, we spent so much time chasing down numbers, fixing mismatches, and worrying about audit gaps. Now, everything’s traceable. The data makes sense, the pipeline is transparent, and we can finally focus on preventing issues – not just reporting them.”

3. Logic managed directly (No-Code support): HSE engineers can now update CO₂ factors, thresholds, or formulas directly in the platform’s no-code interface.

“When we need to update a CO₂ factor, we can do it ourselves immediately. No need to wait for IT support or change any code. It gives us more control and helps us respond faster to regulatory changes.”

Conclusion

UNLSH enables HSE teams to take control of emissions reporting. It supports a shift from reactive compliance to proactive risk management.

This is not just a digital upgrade - it’s a frontline tool for HSE empowerment.
