A penny saved often becomes a well-deserved penny earned on the bottom line, even in the most efficient bakeries today. However, those coins begin to add up when the currency is converted to fewer megawatt hours of electricity or other metrics that gauge energy usage. But saving money is not the only reason why Campbell Soup Co., Camden, N.J., joined more than 2,600 businesses and other groups in signing the “We Are Still In” declaration in 2017.

“Our commitment to addressing the risks of climate change and reducing our environmental impact is unwavering,” said Megan Maltenfort, senior manager, corporate social responsibility, Campbell Soup, which owns Pepperidge Farm.

“Environmentally responsible business practices are integrated throughout the Campbell organization, enabling us to sustainably grow, source, produce and share our food for generations to come,” Ms. Maltenfort continued. “We take our commitments seriously and will continue to work across the organization and along our value chain to drive progress.”

Likewise, Clif Bar & Company, Emeryville, Calif., joined the initiative.

“Climate action has been a fundamental part of our sustainability program from the start, and climate change puts our farming systems, the places we care about most deeply, and our communities at risk,” said Elysa Hammond, vice-president of environment stewardship.

Clif Bar also is driving renewable energy into its supply chain.

“We treat energy like an ingredient,” Ms. Hammond added. “Just like the care we take to source organic and sustainable ingredients for our bars, we also work to use clean, renewable energy to make our products.”

In the end, corporate responsibility is an ingredient for success.
