Gradient’s mission is to cool the world by transforming every home to be more comfortable and healthy for the people who inhabit it — without compromising the environment. Today, heating and cooling equipment emits more greenhouse gas emissions than the entire transportation sector, and expansion in the use of cooling is projected to double these emissions in the next 30 years. However, comfortable buildings are critical for health and productivity, especially among communities that are vulnerable to the effects of climate change. Gradient’s vision is a future where everyone has access to comfortable buildings that are fully decarbonized. Our launch product is a direct-to-consumer high-efficiency and low-carbon heat pump.
