11 Cities Showing What Bold Climate Action Looks Like

3. Curitiba, Brazil

The city of Curitiba is a winner of the C40 Awards 2016 in the Sustainable Communities category. Since 1986, Curitiba's Urban Agriculture Program has used empty public spaces to encourage communities to grow their own food. In addition to creating sustainable communities, the project reduces greenhouse gas emissions: directly through carbon sequestration in soil and biological nitrogen fixation by legumes and non-use of chemical nitrogen fertilizers; and indirectly by reducing food and waste transport distances, composting organic waste, reduction of "heat islands" and creating environmental awareness.

2018 saw a number of studies pointing to the outsized climate impact of meat consumption. Beef has long been singled out as particularly unsustainable: Cows both release the greenhouse gas methane into the atmosphere because of their digestive processes and require a lot of land area to raise. But for those unwilling to give up the taste and texture of a steak or burger, could lab-grown meat be a climate-friendly alternative? In a first-of-its-kind study, researchers from the Oxford Martin School set out to answer that question.

Hurricane Florence, which battered the U.S. East Coast last September, left a trail of ruin and destruction estimated to cost between $17 billion and $22 billion. Some of the damage was all too visible—smashed homes and livelihoods. But other damage was less so, like the long-term environmental impacts in North Carolina from hog waste that spilled out over large open-air lagoons saturated in the rains.

Hog waste can contain potentially dangerous pathogens, pharmaceuticals and chemicals. According to the state's Department of Environmental Quality, as of early October nearly 100 such lagoons were damaged, breached or were very close to being so, the effluent from which can seep into waterways and drinking water supplies.
