The 8 best companies for the world, according to a major sustainability nonprofit

No business is immune from making bad decisions, but some companies do more good for the world than others.

Every year, the nonprofit B Lab rolls out its list of the best companies for the world - that is, the top 10% of B Corp-certified scorers on the B Impact Assessment, a sustainability management tool that examines a company's effect on the environment, workers, and community.

B Lab certification requires companies to meet a rigorous set of criteria related to corporate social responsibility, including environmental and legal accountability. It's a high benchmark in and of itself, so a B Lab-certified company that also scores highly on the impact assessment is a big deal.

This time around, over 500 companies were eligible for the Best for the World awards.
