Most of us have heard of “Meatless Monday,” a common phrase in the U.S. ever since Sid and Helene Lerner first launched the initiative back in 2003. Entrepreneur and activist David Yeung applied the concept in Asia in 2012, starting the “Green Monday” campaign to help transition the meat-heavy culture towards a healthier, plant-based future. Cutting down on demand for meat has a huge upside, not just for human health but for planetary wellness: the greenhouse gases emitted by global meat production currently outpace all transportation or industrial emissions, and nearly two thirds of the world’s agricultural land is used to raise animals. In China, land pollution and import dependence exacerbate these problems. But Yeung sees solutions. He’s leading the growing movement to make sustainable consumption accessible to all through Green Monday and with his Green Common stores in Hong Kong and beyond, which sell everything from the innovative “Omnipork”—a delicious pork replacement developed for the Asian palate—to dairy alternatives and innovative snacks. The goal: to empower everyone from corporations to the general public to make low-carbon, plant-first choices. And as Yeung’s work has shown, it’s already working; Green Monday’s impact prevented nearly one billion tons of carbon emissions last year.
