To reduce obesity and depression, we need more nature in our lives.

by AveryGrafton Posted on March 22, 2017

U.S. cities are packed with about 5 million medium-sized buildings — schools, churches, community centers, apartment buildings. Most use way more energy than they should. Many also have poor airflow and dirty, out-of-date heating and electrical systems. Those conditions contribute to high inner-city asthma rates and other health concerns.

“These buildings are actually making children sick,” says Donnel Baird, who grew up in such a place. His parents, immigrants from Guyana, raised their kids in a one-bedroom Brooklyn apartment, relying on a cooking stove for heat. Baird eventually moved to the South and then attended Duke University, before returning to New York as a community organizer in 2008.

In 2013, Baird launched BlocPower, which provides engineering and financial know-how to retrofit city buildings. The technical part is cool: Engineers survey structures with sensors and smartphone apps, figuring out the best ways to reduce energy use, like replacing oil boilers with solar hot water. But the financing is critical; BlocPower builds the case for each project and connects owners with lenders. It has already retrofitted more than 500 buildings in New York and is expanding into Chicago, Philadelphia, and Atlanta.

“The biggest way for us to reduce carbon emissions right now,” Baird says, “is efficiency.”

Meet all the fixers on this year’s Grist 50.

North America pledges to deliver 50 percent zero-carbon energy in less than a decade

Climate change will be front and center at the North American Leaders’ Summit this week in Ottawa, the annual meeting between the prime minister of Canada and the presidents of Mexico and the U.S.

In addition to President Obama’s address on climate change, the leaders of the three nations will announce that Mexico will be joining an agreement between the United States and Canada to regulate methane leaks. They will also pledge to generate half of the continent’s electricity from clean energy sources by 2025. The target, up from 37 percent today, will require increasing include wind, solar, hydropower, nuclear energy, and carbon capture technology, according to the New York Times.

Environmentalists, however, are mixed on both nuclear energy and carbon capture technology, which doesn’t exist in any scalable way right now. There are only eight carbon-capture projects currently operating in the world, including a handful in the U.S and one massively expensive “clean coal” plant in Canada.

Still, the announcement coming Wednesday isn’t nothing. “This agreement means the United States will dramatically increase the amount of clean, renewable energy we get from sources like wind and solar within the next decade,” said Sierra Club Executive Director Michael Brune.

Here’s hoping.
