PARIS/BERLIN (Reuters) - Kellogg K.N, Sony 6758.T, Coca-Cola Enterprises CCE.N and a group of other companies have committed to targets certified by independent assessors to cut their carbon emissions, they said on Tuesday.

The initiative came as negotiators gathered in Paris try to reach an accord on reducing greenhouse gas emissions, and is intended to go beyond the often vague promises of corporate action on the issue.

U.N. Global Compact, a voluntary U.N. scheme, and non-governmental organizations including the U.S.-based World Resources Institute (WRI) have been attempting to persuade business to set carbon goals following the 1997 Kyoto Protocol.

The WRI and its partner organizations said more than 100 companies had committed within the next two years to set targets, assessed on the basis of U.N. standards as a meaningful contribution to warding off a global average temperature rise of more than 2 degrees Celsius, viewed as a threshold for potentially catastrophic climate change.

Coca-Cola Enterprises (the European bottling partner of Coca-Cola Co KO.N), Dell, Enel ENEI.MI, General Mills GIS.N, Kellogg, NRG Energy NRG.N, Procter & Gamble PG.N, Sony and Thalys have already had goals approved equating to nearly 2 billion barrels of oil not burned over the lifetime of their targets.

Kellogg, which like other food companies is sensitive to extreme weather that inflates the cost of ingredients and makes them scarce, committed to a 15 percent reduction in emissions intensity per tonne of food produced by 2020 versus 2015, the joint statement said.

Kellogg added it had also set a longer term goal to cut emissions across the value chain, including suppliers, by 50 percent by 2050, and from its own operations by 65 percent.

“It’s a core business issue in terms of, can we have enough access to foods over time?” Diane Holdorf, chief sustainability officer at Kellogg, said in Paris. “Security of supply is critical to our business.”

Ignacio Gavilan, sustainability director at Consumer Goods Forum, a grouping of 400 of the world’s top retailers and manufacturers, said firms needed to set aggressive climate goals or their brands could come under attack from social media pressure.

“Given today’s transparency, companies cannot go for the minimum common denominator,” he said.

Some pension funds, which take a long view, say they favor companies that have reduced their carbon exposure and that compelling emissions promises distinguish firms with strategies that can increase shareholder value.
