Thanks to certifications like fair-trade and LEED standards, we can support businesses that care about sustainability. But how do we know if a company offers men and women equal opportunities? A new certification, EDGE, rates companies based on how gender-equal their workplace is. Edge takes into account five metrics including pay difference between sexes, recruitment and promotion opportunities, leadership development, work flexibility, and company culture. But instead of just applying a score to a business, EDGE looks at efforts the business is making to become more gender equal, and rates them on progress. Companies will be able to use EDGE to judge how effective their gender equalizing programs are.
