1. CDP Supply Chain

disclose climate and water
information through CDP
Key results:
- Became the only energy company
named to CDP’s supplier
engagement leaderboard
- Achieved a first-year supplier
response rate of 34% for climate and
22% for water

2. Supply chain
carbon/water
footprint
NRG partnered with Trucost to calculate
its supply chain footprint and found:
- Fossil fuels account for 58% of
spending, but 94% of supply chain
GHGs and 71% of water
- Transitioning from coal to gas could
increase supply chain footprint
