- Emissions increased 5% from 2022 to 2023, primarily due to reductions in clean energy usage and the browning of the U.S. electricity grid.
- Decarbonizing the business and value chain depends on factors beyond control, including political, economic, regulatory, and geopolitical conditions, supply chain and labor issues, supplier emissions reductions, the evolution of carbon offset markets, and investment and innovation to close gaps in available technology and infrastructure.
