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

Refrigerants

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.

The potential climate crisis looms in the not-too-distant future. The concentration of greenhouse gasses in our atmosphere grows at an unchecked rate. If this trend continues unhindered, big problems lie ahead for us all. We're here to challenge what's possible in the critical decade ahead. Our landmark promise: The Gigaton Challenge. We are committed to helping our customers achieve a cumulative 1 gigaton reduction in their carbon footprint by the year 2030. And we are challenging our industry and the rest of the world to join us. How big is a gigaton? One billion metric tons of emissions. It is equivalent to the entire annual emissions of France, Italy, and the United Kingdom combined. It's a big goal, but we are optimistic and ambitious. The need for climate action has never been more urgent. Bold action has to start now to bend the curve against catastrophic global warming. Heating and cooling buildings, as well as transporting refrigerated goods, contributes almost to one fourth of the total global carbon emissions. To push this curve down, our solutions help reduce the overall energy required to power the critical infrastructure our world depends on. Through innovation, we are advancing technologies to expedite the transition to a cleaner, safer, and healthier energy production future. We've deployed low-global warming potential refrigerants and are accelerating clean technologies to address these trends ahead of regulations. With low footprint and connected transport solutions, we reduce loss in the cold chain ensuring precious resources like food and medicine make it to their destinations and people who need it. Our customers trust us to help them build safer, more resilient, and efficient operations. We know we can meet the call while also providing positive outcomes for the environment. Sustainability is at the center of our business and we are standing at the forefront of a movement to solve global climate crisis. We are proud to be Trane Technologies.
