Is it Chicago’s O’Hare International Airport, or Dubai International? Both apparently. But it depends on the metric. If you go by number of flights, then O’Hare is the world’s busiest airport (881,933 flights in 2014), dethroning Hartsfield-Jackson Atlanta International Airport (868,359) after 10 years at the top – by this way of measuring. However, if [...]

As 2015 begins, the road to the crucial COP-21 summit here in Paris (where I am based) is being outlined by the French government, the UN, and a huge number of other actors and NGOs. But the first big question might be, is it crucial at all? The 2009 UN summit in Copenhagen was famously [...]

For this #MapMonday we return to Yale’s Environmental Performance group, featured previously here on #MapMonday. The newly released biodiversity map brings together a whopping amount of data to detail the state (quality not just quantity) of species around the world, and while the staggering diversity of life on our planet is breathtaking (and sometimes pretty [...]

Does Uber Make Cities More Energy Efficient?

It seems you can’t read an article about new mobility or the sharing economy without stumbling across Uber; the mobility service that sprung up in 2009 to only five years later become valued at more than Avis, Hertz, or Sony. Yes, Sony. Two weeks ago, I found myself using the service for the first time, [...]

The prevalence of pesticides and other chemicals may seem like something of a bygone era, one marked by Silent Spring and the Bhopal Disaster, but the grim reality is that they are unfortunately very much around. Whether it is BPA in your water bottle or neonicotinoids decimating bee populations, action has not been uniform. To [...]

You may recently have read about climate change and North Carolina for all the wrong reasons, entailing laws designed to forbid the mentioning of the term “climate change” as well as outright banning measurements of sea-level rise. At the heart of this drama, is elevation mapping technology applied to climate change to better understand future [...]

Few tourists travel explicitly to see a city’s or country’s mode of transportation, but I dare say that besides transport nerds such as myself, there are examples which qualify as must-see, including Japan’s Shinkansen high-speed train, Lisbon’s old tram system, and the streetcars of New Orleans, among others. While Paris is most recently known for [...]

Fuel/Cost Savings of Improving Fuel Economy from 12->15 mpg = 30->60 mpg

Fuel economy is not as straight-forward as you might think. Image courtesy: fragallo

Consumer tip-of-the-day: increasing efficiency of fuel economy on a miles-per-gallon scale is not linear, as more miles-per-gallon (mpg) are initially better for your wallet and the planet than you might expect, and eventually trail off with diminishing returns. Last week, a friend pointed out a good blog post by Nicholas Chase and the Energy Information [...]
