The Gigaton Challenge

Doing What It Takes to Make a (Huge) Difference

As a pure play climate innovator, we are uniquely positioned to lead a movement to reduce greenhouse gas (GHG) emissions.

And we’re taking advantage of the opportunity in a big way. How big?

One billion metric tons

One Gigaton of CO2e

We’re reducing one gigaton – one billion metric tons – of carbon emissions (CO2e) from our customers’ footprint by 2030.


This is the largest customer climate commitment made by any B2B company, and our math shows that this reduction could equate to 2% of the world's annual emissions — or, the annual emissions of Italy, France and the U.K. combined.

Why We Need to Address Decarbonization

Aging buildings

Aging Buildings

Large buildings are used longer than other buildings, and older buildings use more energy. The key to energy efficiency and greenhouse gas reduction is ensuring that these buildings can be maintained, retrofitted, and energy managed successfully.

Energy Intensity

Buildings consume about 40% of the energy produced in the United States. Additionally, a third of a building’s energy use is from HVAC, and energy demand for cooling will more than triple by 2050.

Carbon Emissions (CO2e)

Approximately 15% of the world’s carbon emissions (CO2e) come from the heating and cooling of buildings. As urbanization accelerates and the world gets warmer, that figure could approach 25% by 2030.

Food Waste

If food loss and waste were its own country, it would be the third-largest greenhouse-gas emitter.

How We Are Rising to the Challenge

We are directly addressing climate change by changing the way the world heats and cools buildings and moves refrigerated cargo. From advancements in refrigerants and technology, to forging key partnerships, we’ve created a multi-pronged strategy to succeed.

Chiller facility


We started offering customers HVAC and transport refrigeration systems with next generation refrigerant in 2014. Next, we established the EcoWiseTM portfolio to endorse our products that are designed for lower environmental impact and higher efficiency. Now, we have expanded the portfolio with new high-efficiency chillers, designed to reduce building emissions with low global warming potential refrigerants.
