Even though most large electronics companies now routinely measure and report carbon emissions for power generation and purchases (referred to as "Scopes 1 and 2" by the Greenhouse Gas Protocol), they've had difficulty reporting the highest emitting and costliest "Scope 3" activities. This has been frustrating, because Scope 3 activities - supply-chain and corporate purchases, product transportation, customer use and disposal of products, air travel, and employee commutes - represent the largest opportunity for both reducing greenhouse gas emissions and enhancing profitability at the same time.
The good news is that the GHG Protocol creators WBCSD/WRI (World Business Council for Sustainable Development and the World Resources Institute) are now bringing standards to the previously elusive "Scope 3" category.
