The Simplest Way to Improve Cities: Remove Cars

For the last 100 years streets have been destroyed by the automobile and corporations that profit from excessive use of cars. This has caused harm to the wellbeing of people both in and outside the cars as well as countless environmental issues. It does not have to be this way, and cities from Paris to Seoul have shown us that we can modify our cities to reclaim them from the scourge of the automobile industry. Over at Fast Company they have a nice list of five things cities can do to improve life for everyone in the.

Reversing car-centric design is not a utopian dream. Cities around the world are already doing it. Paris is removing 70,000 parking spaces to make room for bikes and trees. Barcelona is expanding its network of “superblocks” that prioritize pedestrians and eliminate through-traffic. Oslo removed cars entirely from its city center and saw foot traffic, and local business, surge. Cities in the Global South are pioneering new forms of green micormobility, such as Jakarta where the government has set a target of electrifying 2.1 million motor cyles by the end of 2025

We Can Use Container Ships to Sequester CO2

Years of researchers looking into carbon sequestration have concluded two things:
1. It’s far better to reduce emissions than rely on sequestration to avoid climate catastrophe
2. Ocean-based sequestration is more efficient than direct air capture.

A team of researchers have found a way to get container ships to help with sequestration of carbon into the ocean by using an accelerated natural process. It’s well known that modern fossil-fuel powered shipping is very bad for the planet so the researchers wondered what if we could leverage the movement of ships on the water to spread limestone over greater distances? They modelled it out and this approach of using ships as a way to spread the carbon sequestration method is quite efficient and better than a stationary setup.

Calcium carbonate dissolution is the dominant negative feedback in the ocean for neutralizing the acidity from rising atmospheric carbon dioxide. Mimicking this natural process, the accelerated weathering of limestone (AWL) can store carbon as bicarbonate in the ocean for tens of thousands of years. Here, we evaluate the potential of AWL on ships as a carbon sequestration approach. We show a successful prediction of laboratory measurements using a model that includes the most recent calcite dissolution kinetics in seawater. When simulated along a Pacific shipping lane in the Estimating the Circulation and Climate of the Ocean–Darwin ocean–general circulation model, surface alkalinity and dissolved inorganic carbon increase by <1.4% after 10 years of continuous operation, leaving a small pH and partial pressure of carbon dioxide impact to the ocean while reducing 50% carbon dioxide emission in maritime transportation.

Cargo Bicycles Are More Efficient Than Cargo Vans

Delivery vehicles are a significant cause of delays in city as they stop and block other transportation modes at a frequent basis. I’m sure everyone can relate to being frustrated while a truck or van blocks a bike lane (or car lane) while they unload. Urban planners and logistics professionals need to think more about using cargo bikes to help with the flow of traffic while also reducing gross emissions. Cargo bikes are actually more efficient than vans when it comes to urban deliveries. This is particularly worth noting when thinking of opening up streets to people as some argue that deliveries are a key reason we need to close streets to people (and only allow vehicles to be on the road).

When delivering goods in central Brussels the electric Bullitt cargo bikes covered 30% shorter routes, and travelled at 16 km/h versus 11 km/h for vans constrained by congestion, according to the study. The cargo bikes were over 2 times faster than vans using 48 min. versus 99 min. on a typical 8.5 km bike route in Brussels urban centre.

Over a month and a half, the cargo bikes delivered 10.1 packages per hour on average, while vans were able to deliver 4.9 packages per hour to the same destinations. Bikes bypass traffic jams, take shortcuts through streets closed to through traffic and ride to within 30 metres of delivery points on average, minimising walking time. Meanwhile, previous studies have shown that vans can spend up to 25 min per stop searching for parking.

Batteries Still Work in Winter

The myth that batteries are useless in the winter continues to spread despite the overwhelming evidence to the contrary. This myth has slowed the uptake of elective vehicles, which is a bad thing. The CEO of a an EV car company is trying their best to dispel that myth and get consumers to understand that batteries do work even when it’s cold outside. In fact, fossil fuel cars which are a direct cause of the climate crisis are worse than EVs in the winter.

“The number of stories that talked about EVs that weren’t operating properly in that time was staggering,” Scaringe said. “There wasn’t a single story about the thousands and thousands of combustion vehicles that didn’t start that morning because of the cold weather.”

While EVs have gotten a bad rap when it comes to cold weather, a recent study showed the challenges that EVs face from extreme cold weather are actually less than those encountered by gas-powered cars, concluding that EVs are “almost twice as good as fossil cars in the cold.”

“The desire to tell a negative story was so strong and so surprising to me — it was so biased,” Scaringe told TCD. “All we can do is continue to try to balance the story with the facts and a true story.”

Of course, the best thing to do is not drive any car; and we should focus on sustainable transportation solutions like bicycles and public transit. Cars are harmful not just because of their emissions.

Bike Lanes are Really Good for Businesses (seriously, there are too many studies proving this)

Bike lanes are good for business and everybody knows it, except for business owners and local politicians afraid for of small minded businesses. Over at Business Insider they’re running an article that summarizes the current knowledge about bike lanes and how good they are. Like anything, there are winners and losers when it comes to change in the built environment and it’s clear some stores do better than others. The key thin is no business regrets having bike lanes once they are in. Yes, bike lanes are good for business.

The most effective way to deal with opposition from local businesses is to just get the bike lanes built. Before-and-after surveys tend to show that in the long run, everyone winds up satisfied. “It’s a political question, and oftentimes it’s a very divided community when it comes to these types of projects,” Poirier says. “But once a street is changed, generally speaking, after six months or a year, nobody remembers what it used to look like. It’s the new normal.” All the data in the world may prove that bike lanes are good for business. But nothing beats experiencing them.
