Key metrics for a carbon ledger include total carbon emissions, emissions intensity (emissions per unit of output), and emissions by scope (Scope 1, 2, and 3). Total carbon emissions provide an overview of the organization’s carbon footprint. Emissions intensity helps measure efficiency improvements over time. Scope 1 covers direct emissions from owned or controlled sources, Scope 2 accounts for indirect emissions from the generation of purchased electricity, and Scope 3 includes all other indirect emissions in the value chain. Tracking these metrics helps in identifying areas for reduction and setting benchmarks.
Key Takeaway: Track total emissions, intensity, and scope-specific metrics for effective carbon management.
