Carrier's Gigaton Goal

The urgency of climate change requires us to be bold, to innovate and to disrupt. The future demands it. 

Reducing the carbon footprint of our products in use and reducing the impact of food loss in our customers’ operations represent the biggest impact we can make to help address climate change. That’s why we’ve set an ambitious goal to reduce our customers’ carbon footprint by more than 1 gigaton by 2030.

~68M metric tons of greenhouse gas emissions avoided from products sold and avoided food waste in 2020, which is equal to the energy use of 8M+ U.S. homes in one year.

How we are meeting the Gigaton Goal:

Investing over $2 billion to develop healthy, safe, sustainable and intelligent building and cold chain technologies and solutions that incorporate sustainable design principles and reduce lifecycle impacts.

Inventors First. Leaders Always. keyboard_arrow_right

Delivering efficient, innovative products throughout our portfolio that minimize customer energy use and emissions.

Next-Generation Research & Design keyboard_arrow_right

Using lower global warming potential (GWP) refrigerants, in addition to our natural refrigerant technologies, to reduce the greenhouse gas (GHG) footprint of our products while in use.

Expanding our service and digital solutions that use artificial intelligence- and Internet of Things-enabled data insights and performance monitoring to help customers reduce their energy use.

Extending sustainable cold chains. More than one-third of all food produced is wasted every year, resulting in an estimated 4.4 gigatons of GHG emissions. The adoption of cold chain technology – refrigeration along the supply chain – can greatly reduce food loss and waste.

How avoided greenhouse gas emissions are measured

Carrier is providing higher energy efficiency, lower GWP refrigerants and cleaner equipment, allowing our customers to avoid GHG emissions. Progress against Carrier’s Gigaton Goal estimates avoided GHG emissions from the installation of high-efficiency and lower GWP refrigerant Carrier air conditioning, heating and refrigeration systems and from Carrier’s energy services businesses, beginning in 2020 through 2030. 

The model compares projected GHG emissions from available Carrier products to emissions from representative baseline products, with the difference representing the estimated avoided emissions. The model also incorporates energy savings as measured from energy service contracts. We intend to include additional Carrier products, services and businesses in these calculations as data becomes available. 

Avoided GHG emissions from high-efficiency and lower GWP refrigerant technologies are calculated by estimating the lifetime expected avoided emissions from products sold in the year of sale for each year reported. 

The model also includes avoided net GHG emissions from food waste across the same time period. As global markets and infrastructure strengthen, so too does the ability to sustainably refrigerate food in these emerging markets, reducing the amount of food lost or wasted along the food supply chain. Referencing third-party research, Carrier estimates the amount of avoided food waste and its associated GHG emissions through the adoption of cold chain technologies. We account for the avoided GHG emissions within the year of sale only.


Progress toward our Gigaton Goal includes the majority of products in Carrier’s global portfolio. Baseline performance is set against industry and government standards. The model includes the avoided GHG savings from our lower GWP refrigerant products. GHG emissions savings generated from Carrier’s energy services businesses are also captured in the model. The food waste model accounts for the reduction of food loss and associated GHG emissions resulting from the adoption of cold chain technologies in emerging economies.
