Kellogg plans to cut greenhouse gas emissions by 65%.

PARIS — The Kellogg Co. on Dec. 8 announced several steps in its commitment to climate action, including plans to cut greenhouse gas (G.H.G.) emissions by 65% across its operations, known as Scope 1 and 2, and, for the first time work with suppliers, known as Scope 3, to help reduce their emissions by 50% by 2050. The goals were announced as part of the New York Times Energy for Tomorrow Conference being held in Paris.

“Kellogg is more than a business,” said John Bryant, chairman and chief executive officer of Kellogg. “We care about nourishing people with our foods, feeding those in need, nurturing our planet, and living our founder’s values. People care about their food, where it comes from, the people who grow and make it, and that there’s enough for everyone. We must live our values and communicate with transparency to earn our seat at millions of tables every day.

“Science shows that climate change will reduce food productivity and food security at the same time our world’s population is growing and requiring us to feed more people with fewer natural resources. That’s why Kellogg is working on multiple fronts to address the risks climate change poses. Today, we’re joining others in Paris taking action to reduce greenhouse gas emissions to limit the earth’s temperature increase to 2 degrees Celsius.”

Kellogg, which since 2008 has reduced G.H.G. emissions from its manufacturing facilities by approximately 12%, said it is focusing on its new goals because it recognizes that upstream agriculture emissions and manufacturing are the largest sources of emissions in its supply chain. The new targets are an extension of the 2020 global sustainability goals Kellogg set in August 2014, when the organization announced commitments to:

• further reduce greenhouse gas emissions in its own operations;

• increase the use of low carbon energy; and

• expand commitments into its supply chain by requiring all key suppliers to measure and publicly disclose their own emissions and reduction targets.

Kellogg’s efforts also include support for smallholder growers and farmers through Climate Smart Agriculture (C.S.A.). The company said it already has committed to supporting 15,000 smallholder growers by 2020 to increase adoption of C.S.A. By 2030, Kellogg said it expects to have supported the livelihoods of 500,000 farmers through partnerships, research and training on C.S.A.

“We recognize the interconnected and inter-reliant nature of our business with suppliers, farmers, customers, consumers and governments,” Mr. Bryant said. “These types of commitments require cooperation across the full supply chain. That is the only way we can truly be successful.”

Kellogg said it based its new goals on the Science Based Targets, a joint initiative by CDP, the UN Global Compact, the World Resources Institute, and the W.W.F.
