The new goals and metrics build on Cummins’ 2020 goals. While the company did not achieve every 2020 goal, they drove significant benefits. The company achieved four of its seven principal 2020 goals, established as part of Cummins’ first sustainability plan in 2014:  Cummins reached a 53% reduction in water use adjusted by hours worked in 2020. The goal was a 50% reduction.  The company worked with customers to exceed the Cummins’ goal of a run-rate reduction of 3.5 million metric tons of carbon dioxide from the company’s products in use, achieving a 4.9 million reduction in 2020.  Thirty-five Cummins locations achieved the company’s definition of Zero Disposal sites— five above the goal of 30.  Sixteen Cummins sites achieved the company’s definition of Water Neutrality. Cummins’ goal was 15. Meanwhile, the company narrowly missed two goals. Cummins recorded a 93% recycling rate while the 2020 goal was 95%. The company was within a percentage point of reaching Cummins’ goal of a 32% reduction in energy use adjusted by hours worked and then fell back to a 27% cut in 2020, in part because of the pandemic. Company leaders say setting aggressive goals is important to achieve environmental progress.
