Ingersoll Rand said it would cut greenhouse gas emissions by 50 percent within six years as part of an effort to reduce climate change.

The parent company of HVAC market companies Trane and Thermo King made the announcement at a United Nations Climate Summit Sept. 22.

The three main parts of Ingersoll’s pledge include:

A 50 percent reduction in the greenhouse gas refrigerant footprint of the company’s HVAC construction products by 2020 and lower global warming potential alternatives by 2030.

A $500 million investment in green HVAC product-related research and development over the next five years.

A 35 percent reduction in the greenhouse gas footprint of the company’s office buildings, manufacturing facilities and fleet within six years.

“Energy efficiency requires action now and can be the most effective way of reducing greenhouse gas emissions,” said Ingersoll Rand Chairman and Chief Executive Officer Michael W. Lamach. “We are leading our industry toward a more sustainable world and are signaling to our customers, employees and shareholders that our future products will match our legacy of efficient, reliable and sustainable solutions. When we create more sustainable choices, improve our operating footprint globally and continue to develop lower greenhouse gas emission options, our customers – and the climate – benefit.”
