Zeroing In: Carbon Neutral 2050

Now on the menu: traditional beef, grass-finished beef, soy meat and ― possibly sometime soon ― even lab-grown meat. Thanks to a growing awareness of sustainability, more and more people are seeing how food choices have an impact not only on their health, but also on the health of the planet. We'll meet the ranchers, dairy farmers and food entrepreneurs who are exploring new ways to satisfy our appetite while cooling down our sizzling Earth.

From Milan to New York to Tokyo, the buzziest fashion statement is ... sustainability. One Italian brand is replacing nylon fiber with a material made from ocean plastic; a California consignment shop is inspiring a generation of thrifters to reduce their carbon footprint; and a denim shop in Tokyo's ritziest neighborhood aims to make its operations carbon-neutral by 2050. We'll hit the ateliers and runways to see how cutting-edge designers are trying to keep us -- and our planet -- looking good.

In Bangladesh, rising waves rob humble islanders of their livelihoods. In California, wildfires and heatwaves are unbearable for those without the means to protect themselves. And in Japan, floods force scores of elderly residents into temporary housing, away from their beloved communities. Climate change is overwhelmingly caused by a wealthy few, but felt more acutely by the Most Affected People and Areas, or MAPA. We find out why the answer to this crisis lies in listening to their voices. Host: Catherine Kobayashi Guest: Greg Dalton, Journalist and Host, "Climate One"

Scientists who venture to the most perilous parts of Antarctica tell us the massive "Doomsday Glacier" is melting at an unprecedented pace. Our carbon emissions are having a potentially catastrophic effect on the world's sea levels, and we are in a race against time to avoid a global average temperature rise of 1.5 degrees Celsius by the year 2025. Entrepreneurs and researchers lead the way with innovative attempts to both reduce and capture CO2, but the fight for our future is not theirs alone.

City dwellers often refer to life in the "concrete jungle," but most probably aren't aware of the fact that cement accounts for 8% of global emissions. Innovative efforts are underway to decarbonize the industry, so that the infrastructure and architecture we rely on can help to provide a greener future. In partnership with a US public broadcaster, we zero in on some of the researchers who are pushing the boundaries by turning alternative materials into actual building blocks.

More people around the world are warming to the idea of geothermal energy in the race to help keep our planet cool. If harnessed with care, the vast amount of heat below our feet is clean, stable and virtually inexhaustible. In this episode of Zeroing In, we visit a Japanese community where the locals make full use of the steam rising from below, while our partners at Northern California Public Media cover a pioneering geothermal project in which wastewater becomes a real environmental asset.
