Our approach to quantifying our carbon footprint reflects the complexity of our business. Our team of researchers and scientists have combined cutting-edge life cycle assessment (LCA) science and Amazon Web Services (AWS) big data technology to develop a robust software solution that processes billions of operational and financial records from Amazon’s operations across the world to calculate our carbon footprint. The software estimates carbon emissions for all activities within our system boundary using a dollar-based environmental assessment model, then enhances the accuracy of carbon-intensive activities with detailed, process-based LCA models.
This sounds a lot like a top down approach as outlined by systems like Ecocost or Trucost, then supplemented with bottom up modelling of specific processes
