Turning sustainability reporting into sustainability intelligence

Australia’s energy sector faces increasing pressure to deliver sustainability reporting that is not only compliant but also credible and transparent. Regulatory obligations like the National Greenhouse and Energy Reporting (NGER) Scheme – Australia’s national framework for reporting greenhouse gas emissions, energy production, and energy consumption – combined with growing investor expectations and public scrutiny, mean providers must measure and manage their environmental and social impact more effectively.

The challenge? Sustainability data that is fragmented, duplicated, and siloed. Without a single, consistent view of all metrics – across environmental, operational, and social domains – reporting becomes slow, reactive, and disconnected from decision-making.

The cost of disconnected data

Even with modern platforms, many organisations still wrestle with manual, time-consuming reporting processes. Data is pulled from multiple systems, calculations are checked repeatedly, and results are often dependent on IT teams or external consultants to validate.

This leads to:

• Limited transparency – stakeholders cannot easily trace where data originated or how it was calculated.
• Bottlenecks – reliance on technical specialists slows delivery and reduces agility.
• Inflexibility – new requirements, like biodiversity metrics or sustainability-linked loan reporting, stretch existing systems.
• Data quality challenges – inconsistencies in emissions factors, incomplete datasets, and lack of version control erode confidence in reported results.

Disconnected systems make it harder to model future scenarios, measure social program outcomes, or adapt to new obligations. Instead of being a continuous business capability, reporting remains an annual scramble.

From proof of concept to connected capability

One51 delivered a proof of concept for a major Australian energy provider, with Microsoft Sustainability Manager at its core. The objective was clear – unify data sources into a trusted, business-owned capability that could scale with changing needs.

People

Workshops aligned reporting objectives, sustainability goals, and team skills. Business users were trained to manage sustainability data themselves, reducing reliance on technical teams and shifting ownership to those closest to the data.

Process

A tailored data framework brought all relevant sources together, mapping to NGER requirements, internal KPIs, and emerging priorities like biodiversity and social value. By linking environmental and social metrics, reporting could reflect a more holistic view of performance.

Technology

Microsoft Sustainability Manager was integrated with Microsoft Fabric to create a Sustainability Data Hub, applying Australian-specific emissions factors for precise CO₂-e calculations and enabling a single, consistent view across domains.

Measurable impact

• 50–70% less manual effort – reporting prep reduced from 10–14 days to 3–5 days.
• Unified, trusted data replacing duplicate datasets with a single source of truth.
• Audit-ready transparency with clear mapping of sources and factors.
• Self-service capability for business teams to load, validate, and update data.
• Future scalability for Scope 3 tracking, nature repair metrics, and evolving frameworks.
• Scenario modelling to test the impact of operational changes or new projects before implementation.

Insights from the team

“Requirements are evolving quickly. Systems need to be compliant now but also ready to adapt. Building for change-readiness is just as important as delivering on current needs.”

— Julia Kowalska, Senior Consultant, One51

“Sustainability data lives across multiple systems. Bringing it together in a way that is consistent, traceable, and trusted takes careful planning. The right platform helps, but the real success comes from aligning processes, governance, and skills from the start.”

— Laura Isla Lorenzo, Business Analytics Consultant, One51

Why a connected sustainability capability matters

With new frameworks like ASIC’s climate disclosure roadmap, updates to the NGER Scheme, and global standards such as ISSB emerging, sustainability systems must be:

• Connected – integrating all relevant data into a single, consistent view.
• Accurate – producing results that are audit-ready and credible.
• Accessible – empowering business teams to manage data without technical bottlenecks.
• Adaptable – ready to integrate new metrics and obligations as they arise.
• Continuous – enabling real-time monitoring and adjustments throughout the year instead of annual, reactive efforts.
• Future-proofed – aligned to current regulations while designed to meet emerging global standards.

A connected sustainability capability transforms reporting from a compliance exercise into a strategic asset – enabling faster decisions, deeper transparency, and measurable impact.
