Corporate decarbonization policy has stagnated under geopolitical and ideological divisions. Arguing that anthropogenic
emissions are driven by customer preferences and that such preferences can shift with improved information, I advocate for a new approach: an economy-wide system of reliable and comparable accounts of the embedded emissions in products to allow customers (and investors) to make more-informed decisions aligned with underlying beliefs. Such a robust accounting system can also create its own new demand, and together, these demand signals generate incentives for corporate innovation on more emissions-efficient products. I also offer a theory of change to (progressively) deploy the system worldwide.
