Map Monday: World Carbon Prices

Via Carbon Brief, here’s an (interactive) world map showing the price people pay for a pound of CO2 in each nation around the world. The US has a “per-ton of CO2” price of 85 cents, versus $26.21 in Germany or $3.79 in Canada (for example). Note that this is the “effective carbon price,” which is […]

This chart from the Financial Times is impossible to pass up, showing the health benefits of urban bicycling at different levels of particulate pollution. The article includes a helpful cycling benefits chart generator, where you plug in the current Twin Cities’ PM2.5 air quality measurement and it gives you a cool chart showing the relationship between exercise […]

As you can see, though emissions relative to each other remain largely stable, there is clear trend where transportation emissions are becoming a larger piece of the pie.

In September, 2015, The Journal of Applied […]

Map Monday: Minnesota’s Carbon Donut

I love interactive maps and one got my attention recently. Christopher M. Jones and Daniel M. Kammen at UC Berkeley published a study in 2013 taking data on household carbon footprints to develop carbon profiles of zip codes, cities, counties, and states. They took the carbon profile data and produced an interactive map of the […]
