GreenBiz week in review

A weekly roundup of the news you need to know about.

Cambell's goes pro-GMO labeling

Big Food historically has been a strong foe of new labeling laws for genetically modified foods, but Campbell Soup has become one big exception after laying out a new policy in favor of increased disclosure.

Senior Writer Heather Clancy covers the upshot for sustainability amid the consumer trend toward better ingredients and transparency in the piece "What Campbell's bold new GMO plan means for the food label wars."

Sodexo wades into food waste

Elsewhere in the food industry, an interesting coalition of industry insiders and outsiders — Sodexo, Deloitte, the Closed Loop Fund and Mission Point Capital Partners — are coming together to take on the perennial issue of food waste.

As Senior Writer Barbara Grady reports in her latest piece, the group called Rethink Food Waste through Economics and Data (REFED) estimates that food waste is a $165 billion logistics, efficiency and consumer education business opportunity.

Charting a path to climate resilience

In a special contributed piece from the nonprofit 100 Resilient Cities, author Katherine Michonski chronicles the quest for climate resilience at city scale in in Durban, South Africa, and Boulder, Colorado.

The chief resilience officers of both cities weigh in on how they're evaluating — and responding to — the localized risked presented by climate change.

From e-waste to biopolymers to paper, agricultural waste and all manner of toxic compounds, the wide world of materials represents a massive challenge in the shift to "circular economy" production models where materials constantly are cycled back through supply chains.

Senior Editor Lauren Hepler delves into the disconnect between chemistry and sustainability ambitions in the piece "Why materials will make or break the circular economy."
