A driver planning to make the trek from Denver to Salt Lake City can look forward to an eight-hour trip across some of the most beautiful parts of the country, long stretches with nary a town in sight. The fastest route would take her along I-80 through southern Wyoming. For 300 miles between Laramie and Evanston, she would see, according to a rough estimate, no fewer than 40 gas stations where she could fuel up her car. But if she were driving an electric vehicle, she would see just four charging stations where she could recharge her battery.

Fiat Chrysler Automobiles NV (FCA) is recalling around 965,000 gas-powered cars in the U.S. and Canada after they failed in-use emissions tests conducted by the company and by the U.S. Environmental Protection Agency (EPA), Reuters reported Wednesday.
The company will need to replace the vehicles' catalytic converters, which were shown to deteriorate during driving tests, leading to nitrogen oxide emissions above U.S. limits. Nitrogen oxide is associated with ozone and particulate matter pollution, which has serious health impacts.
For new cars and trucks released in 2017, carbon dioxide emissions reached a record low, and mileage per gallon reached an all time high, according an U.S. Environmental Protect Agency (EPA) report released Wednesday.
The findings are leading many environmental advocates to ask, if Obama-era fuel economy standards seem to be working, why roll them back, as Trump's EPA has proposed?
As of 2018, the commercial aviation industry accounted for 2.5 percent of all greenhouse gas emissions. If it were its own country, it would be the 7th highest emitter on the planet.
Because of this, some climate activists have begun calling on people to reduce the amount of time they spend in the air, or to stop flying all together. Two Swedish moms, for example, got at least 10,000 people to pledge not to fly at all in 2019 as part of their No-fly 2019 (Flygfritt 2019) campaign, as BBC News reported.

Everyone's talking about self-driving, autonomous vehicles these days. Late last year General Motors announced that it will shut down production of several conventional car lines, partly to pour resources into its self-driving car unit, and GM is just one of many companies ramping up such efforts, alongside Google, Tesla, Uber and a slew of others. But what kind of transportation future will this autonomous vehicle revolution bring? And who will it benefit? In a country with an increasing divide between rich and poor, what will this whiz-bang technology mean for marginalized groups such as the poor, people of color, the elderly and those with disabilities?

As cities strive to improve the quality of life for their residents, many are working to promote walking and biking. Such policies make sense, since they can, in the long run, lead to less traffic, cleaner air and healthier people. But the results aren't all positive, especially in the short to medium term.
This year's letter from Bill and Melinda Gates focused on nine things that surprised them. For the Microsoft-cofounder, one thing he was surprised to learn was the massive amount of new buildings the planet should expect in the coming decades due to urban population growth.
"The number of buildings in the world is going to double by 2060. It's like we're going to build a new New York City every month for the next 40 years," he said.
