The Path to Drawdown: High-Efficiency Heat Pumps

Buildings and construction account for roughly 38% of global CO2 emissions and 35% of total energy-use. Over one-third of that is for heating and cooling, which could cut energy use by 30-40% with maximum efficiency.

Heat pumps are the technology that can increase heating and cooling efficiency most effectively. Heat pumps extract heat from the air and transfer it from indoors to the outside for cooling, and from outdoors in for heating. The ground, air, or water can be the source of or outlet for that heat.

Heat pumps are well understood, easy to adopt, and already in use around the world. They can supply indoor heating, cooling, and hot water, all from one integrated unit. With high efficiency, they can dramatically reduce building energy use. When paired with renewable energy sources, they can eliminate almost all emissions from heating and cooling.

According to Project Drawdown, high-efficiency heat pumps need to continue growing mildly between now and mid-century to help achieve decarbonization:

  • <::marker> In 2018 high-efficiency heat pumps accounted for 3% of the market for delivered heat globally
  • <::marker> To stay below 1.5°C of global warming, high-efficiency heat pumps need to grow enough to account for 4.3% of that market by 2060
  • <::marker> That’s 0.86% growth annually between 2018 and 2060

If they can grow at this rate, heat pumps can help avoid up to 9.3 gigatons of GHG emissions.

What We Want to See Improve

Phase Out Fossil Fuel-Based Energy

As of 2020, only 9% of total energy (p. 42) that Lennox consumed came from renewable energy sources. This is unacceptable for a company that purports to be concerned about and working toward mitigating climate change. We urge Lennox to phase out the use of fossil fuels in their operations and transportation, and switch completely to renewable energy and clean fuels as soon as possible.

Reduce Absolute GHG Emissions

Targets are aimed at reducing emission intensity. They report (p. 50) that they plan to share ambitious emissions reduction targets for scope 1, 2 and 3 emissions in the next few years. We hope that these targets will be geared toward reducing absolute - not relative - emissions.

Clean Up Supply Chain

Lennox relies on over a thousand suppliers (p. 29) to provide raw materials and components used to manufacture their products. We applaud Lennox for developing a comprehensive code of conduct for their business partners which includes an expectation for them to adhere to environmental laws and regulations. But we would like Lennox to be even more proactive by emphasizing emissions reductions as a more prominent part of their supplier code of conduct.
