Cargill, the United States' largest privately held company, launched a new sustainability initiative aimed at slashing two billion kilograms of carbon dioxide by 2030, equivalent to removing 400,000 cars from the road.

The company will first partner with salmon farmers on its SeaFurther Sustainability program , setting the goal of reducing the carbon footprint of farmed salmon 30 percent by 2030.

Through the program, Cargill is placing efforts on identifying and sourcing alternative aquafeed ingredients, helping farmers do more with less, and promoting animal welfare.

"Cargill has an opportunity to drive real, positive climate impact for people and the planet," said Pilar Cruz, Cargill Aqua Nutrition president and group leader.

"With our global footprint and view across supply chains, sustainable oceans and sustainable seafood can become a reality if we are all in, partnering with farmers, working across the industry and pulling in the same direction."

SeaFurther will expand to other species such as shrimp in the future, following success with salmon.

The program is an addition to Cargill's slew of strategic partnerships, investments, research and technologies.
