Haulage Emissions Reporting Framework (GHG Protocol Aligned)

Mining haulage operations represent one of the largest sources of Scope 1 greenhouse gas emissions in surface mining, typically accounting for 30-50% of total site-level CO2-equivalent emissions depending on ore type, haul distance, and fleet composition. This reporting framework provides a comprehensive methodology for emissions quantification that satisfies investor ESG reporting requirements, regulatory carbon pricing mechanisms (carbon taxes, emissions trading schemes), and voluntary disclosure standards (CDP, GRI, TCFD). The framework employs a tiered calculation approach: Tier 1 uses fuel consumption data with standard emission factors (IPCC AR6 values), Tier 2 applies equipment-specific fuel consumption curves based on payload, grade, and rolling resistance, and Tier 3 utilizes real-time telemetry data from fleet management systems for granular, trip-level emissions accounting. The framework includes guidance on boundary definition (haul fleet vs. total mobile equipment), allocation methodologies for shared haul roads, and treatment of biofuel blending and electrification transition pathways. Reporting templates support both internal management reporting and external assurance processes, with data quality scoring aligned with GHG Protocol uncertainty assessment protocols.
