Bill Gates backs lab-made carbon butter that tastes like real butter; here's how it is made and what makes it special

In an industry increasingly focused on sustainability and innovation, a remarkable development has emerged from Batavia, Illinois. A company named Savor has created butter made entirely from carbon and hydrogen—without any involvement of animals, plants, or traditional oils. This innovation promises to transform the understanding of dairy fats and their environmental impact.

Backed by billionaire investor and climate advocate Bill Gates, this carbon-based butter offers a solution to some of the food industry’s biggest challenges: reducing greenhouse gas emissions, land use, and reliance on animal agriculture, all while delivering the familiar taste and texture consumers expect.

Traditional butter is primarily composed of fat molecules made of carbon and hydrogen chains. Savor’s innovative process mimics this natural structure, but without animal or plant sources. As CBS News reported, Savor extracts carbon dioxide (CO₂) directly from the air and hydrogen from water. These basic elements undergo heating and oxidation in a controlled industrial process to produce fat molecules chemically identical to those found in dairy butter. Jordan Beiden-Charles, the company’s food scientist, explains:

"The final product looks like candle wax but is actually made up of fat molecules similar to those in beef, cheese, or vegetable oils."
The butter contains only a few simple ingredients: fat, water, lecithin (used as an emulsifier), and natural flavour and colorings. This clean-label approach appeals to modern consumers seeking transparency and simplicity in their foods.



How carbon butter could transform the future of food production


The environmental cost of traditional butter production is significant. It requires extensive farmland to raise cows, feed crops, and produce greenhouse gases — both methane from cows and carbon emissions from agricultural activities.

• Zero greenhouse gas emissions

Savor’s process stands apart because it produces no greenhouse gases during butter manufacturing, addressing a major environmental concern.
Land use reduced by thousands of times. Traditional dairy farming consumes vast areas of land. In contrast, carbon butter production uses minimal space, reducing the land footprint by nearly 1,000 times compared to conventional agriculture.

• Avoiding harmful ingredients like palm oil

Many butter alternatives rely on palm oil, which is linked to deforestation and biodiversity loss. Savor’s product contains no palm oil, making it a more environmentally responsible choice. According to Savor, animal and plant fat production contributes roughly 7% of global greenhouse gas emissions, highlighting the potential climate benefits of switching to lab-made fats.



Carbon butter chocolates set to launch for 2025 holiday season

For any new food product, taste is paramount. Savor’s carbon butter reportedly matches the creamy texture, buttery aroma, and flavor profile of traditional dairy butter closely enough to satisfy chefs and consumers. Without artificial additives or complex chemical ingredients, Savor achieves a pure butter flavor that food experts say is indistinguishable from the real thing.

Savor is already partnering with restaurants, bakeries, and food suppliers to test their product. A notable milestone includes the upcoming launch of chocolates made with carbon butter, scheduled for the 2025 holiday season, demonstrating the product’s versatility. Currently focused on commercial applications, Savor aims to make its butter available to consumers by 2027. This timeline allows for scaling production and building distribution networks.

Kathleen Alexander, co-founder and CEO, shares the company’s vision: "We expect Savor Butter, whether on its own or through partners, to be on store shelves within a few years." Bill Gates’ support further boosts confidence in the product’s market potential and environmental impact.



Bill Gates’ vision highlights carbon butter’s role in sustainable food

Bill Gates, known for championing technologies that tackle climate change, has expressed strong support for lab-grown fats and oils. In his blog, he noted: "Switching to lab-made fats and oils may seem unusual at first, but their potential to reduce our carbon footprint is immense."
This endorsement highlights the broader importance of innovations like carbon butter in addressing global sustainability challenges while ensuring food security.
