When improper waste disposal procedures are producing islands of trash, it may be time to consider the weight of environmental issues. One by one, communities are diverting themselves from fossil fuels to pursue more environmentally friendly energy options. For state-owned vehicles in Sri Lanka, electric and hybrid cars will be stepping in as replacements as early as 2025.
Private owners have until 2040 to replace their cars, tuk-tuks and motorcycles, when the country plans to no longer allow any fossil fuel-burning vehicles on its roads… said [Finance Minister Mangala Samaraweera].
Home to roughly 6.8 million vehicles, Sri Lanka’s transition into electric will benefit the country immensely. To encourage a hassle-free switch, the government is encouraging consumers by cutting taxes on electric cars.
“The tax on electric cars will be reduced by over a million rupees (S$8,851) to encourage motorists to switch to clean energy,” Mr. Samaraweera told parliament.
On the other hand, Samaraweera is also hiking carbon and import taxes to discourage keeping gas vehicles. With inflation on the rise, Sri Lanka’s bumpy ride will hopefully segue into smoother (and sustainable) sailing.
With a rising number of electric buses and taxis headed for the streets, roads are having to undergo adjustments, too. Los Angeles is home to an excess of both trucks and smog. To revamp the deadly duo into something more eco-friendly, Siemens has installed its first electric highway where trucks can charge on-the-go.
“To have the road electrified and have these heavy trucks electrified is just far more efficient from the perspective that you don’t waste fuel, you save energy because the electric motor is far more efficient than the gas motor, and you have no emissions at all,” says Andreas Thon, the head of turnkey projects and electrification in North America.
The trucks are rigged onto overhead wires that run the entire length of the highway. The trucks themselves are cost-efficient, requiring significantly less maintenance than diesel motors. The highway also alleviates battery problems, as they don’t generate enough energy for heavy loads.
Thon says, “With this technology, you permanently feed energy into the truck.”
Siemens also hopes to install charging technology beneath road surfaces — but that will have to wait. After all, it does require a lot more science and a lot more money.
It’s been a year of firsts for the railway system — from going solar to launching its fastest model. Pushing its limits even further, China is test-driving its Autonomous Rail Rapid Transit system, which is fully electric and trackless.
ART bears the physical appearance of a train but it doesn’t rely on following a track. Instead, it follows a virtual route using an electric powertrain and tires. It’s expected to function much like an urban train or a tram, but since there’s no investment cost in laying down rails, it should be much cheaper to implement.
The train can only travel 15 kilometers at a time, but can fully recharge in just 10 minutes. Environmentalists will likely tip their hats off to the new system — it’s entirely emissions free! Smoggy China could surely use more sustainable public transport alternatives. Thankfully, its government has been taking other measures to ensure that its locals don’t further experience pollution-caused health issues.
40 percent of China’s factories have been shut down, and authorities are reportedly working on a timetable to end the sale of gas- and diesel-powered cars.
A round of applause for China — sounds fresh!
The steady rise of electric vehicles will soon leave petrol and diesel cars in the dust. BMW is launching electric buses all over Europe, while the London Taxi Company is replacing old cabs. A few months later, the U.K. remains on top of the eco-ladder, with Oxford planning to eliminate non-electric vehicles.
The scheme aims to cut levels of nitrogen dioxide, the majority of which comes from traffic fumes, by three-quarters.
To give distributors leeway, Oxford will be imposing the ban in 2020, increasing the affected zone by 2035. We all know electric vehicles aren’t the most affordable, so locals may have to do some walking. The plan is projected to cost £7 million, but the city council deems the shift will be well worth it.
Oxford city councillor John Tanner said a “step change” is urgently needed as toxic air pollution is “damaging the health” of residents.
It’s a bold move, Oxford, but hopefully a successful one.
People are constantly on the hunt for ways to keep our air clean. Urban areas are choosing to build vertical gardens. On the other hand, marginalized communities are seeking more eco-conscious cooking alternatives. While every small step is leading us towards a more positive direction, researchers have yet to break ground. Perhaps they now have with recycled waste biochar, a material that tackles air pollution.
Biochar is ground charcoal produced from waste wood, manure or leaves. Added to soil, the porous carbon has been shown to boost crop yields, lessen the need for fertilizer and reduce pollutants by storing nitrogen that would otherwise be released to the atmosphere.
If properly incorporated into farming, researchers project a 67% drop in nitrous oxide emissions in the United States within the next year. This could mean cutting up to $660 million in annual healthcare costs for pollution-related illnesses.
“Agriculture rarely gets considered for air pollution control strategies. Our work shows that modest changes to farming practices can benefit the air and soil too.”
Based on extensive research, biochar seems like it’s worth a shot. After all, there’s nothing to lose except ozone.
