Carbon Accounting and Carbon Neutrality: Personal and Corporate Carbon Footprint Calculation, Reduction Pathways, and the Carbon Offset Controversy
Corporate carbon footprint accounting divides into three “Scopes”: Scope 1 (direct emissions — own boilers, company vehicles); Scope 2 (indirect emissions from purchased electricity and heat); Scope 3 (indirect value chain emissions — employee commuting, supply chain production, product use and disposal). For most companies, Scope 3 represents 70–90% of total emissions, but is the most difficult to account for. The GHG Protocol is the most widely used corporate carbon accounting standard.
Carbon Offset Controversy: Highly Variable Quality
Carbon offsets allow companies to “neutralize” their emissions by funding equivalent reductions elsewhere (afforestation, forest protection, renewable energy). Theoretically sound; practically problematic:
Additionality: would the subsidized reduction project have happened anyway without carbon offset funding? A 2023 Guardian investigation found major carbon credit certification bodies (including Verra) had certified rainforest protection projects with actual emission reductions far below claimed values.
Permanence: California and Australian wildfires burned forests previously considered “permanently sequestered” carbon — forest carbon offsets’ actual effectiveness is seriously questioned.
Higher-quality offset reference standards: Gold Standard (requires additional social/economic co-benefits) and Science Based Targets initiative (SBTi) (requires corporate reduction pathways aligned with Paris Agreement targets) are currently the most credible certification systems.
