In an era of escalating global climate imperatives, GHG accounting serves as the foundational pillar for organisations seeking to quantify and manage their environmental footprint. At SESG, we specialise in measuring Scope 1 (direct emissions from owned sources), Scope 2 (indirect emissions from purchased energy), and Scope 3 (value chain emissions) using the globally recognised GHG Protocol, the gold standard for carbon accounting. As of 2025, with global energy-related CO2 emissions reaching a record 37.8 gigatonnes in 2024 an increase of 0.8% from the previous year this process is more critical than ever for establishing credible baselines and setting ambitious reduction targets. Our comprehensive assessments go beyond basic calculations, incorporating data audits, advanced calculation methodologies, and hotspot identification to deliver precise emission inventories tailored to your operations.

Aligning seamlessly with Australia’s mandatory climate disclosure regime under AASB S2, effective for annual reporting periods beginning on or after 1 January 2025, our service ensures your GHG data supports robust climate-related financial disclosures, including scenario analysis and transition planning. Recent updates to AASB S2, including new educational guidance on GHG emissions disclosure issued in September 2025, underscore the need for verifiable, granular reporting that integrates fossil CO2 trends still rising globally despite mitigation efforts with organisational strategies.
