British rock band Coldplay has announced dates for a world tour in 2022, with the band planning to integrate a range of sustainable features into its concerts to reduce their effect on the environment.

In a statement on its website, the group pledged to make the stadium tour “as sustainable and low-carbon as possible.”

Among other things, it wants to cut consumption, lower its direct CO2 emissions by 50% compared to its previous tour and “recycle extensively.”

While it may appear to be ambitious, the group accepts the tour will “have a significant carbon footprint.” To this end, Coldplay has committed to “draw down more CO2 than the tour produces.”

This will be achieved through the backing of projects focused on areas like renewable energy, conservation and soil regeneration, to name three. Millions of trees will also be planted, including one for every ticket the band sells.

When it comes to powering the gigs themselves, a number of ideas and technologies will be incorporated.

These include: the installation of solar tiles at the arenas; the use of hydrotreated vegetable oil in the group’s buses and trucks when possible; and the installation of a kinetic floor in and around stadiums.

The latter is being rolled out “so that the fans’ movements can be converted into energy and help to power the show.”

In addition, Coldplay said it had partnered with the German automaker BMW to develop what it described as “the first ever mobile, rechargeable show battery.”

While the band is keen to show it is making efforts to tour in a sustainable way, some significant challenges to achieving this goal remain, such as having to fly many thousands of miles around the world in order to play shows.

In an interview with the BBC it was put to Coldplay lead singer Chris Martin that, when rock stars spoke about the environment, there were “always cries of hypocrisy, especially when private jets are being used.” The singer was asked if he was ready for an “inevitable backlash.”

“I don’t mind any backlash at all,” Martin replied. “We’re trying our best and we haven’t got it perfect, absolutely. We always have backlash for everything.”

“And the people that give us backlash for that kind of thing, for flying … they’re right. So we don’t have any argument against that.”

The environmental footprint of aviation is significant. According to the International Energy Agency, carbon dioxide emissions from aviation “have risen rapidly over the past two decades,” hitting almost 1 metric gigaton in 2019. This, it notes, equates to “about 2.8% of global CO2 emissions from fossil fuel combustion.”

Elsewhere, the World Wildlife Fund describes aviation as “one of the fastest-growing sources of the greenhouse gas emissions driving global climate change.” It adds that air travel is “currently the most carbon intensive activity an individual can make.”

In an effort to reduce the environmental effects of its flights, Coldplay claims that when it comes to “all flights, commercial and charter”, it will pay a surcharge so it can “use or supply” sustainable aviation fuel.

In his interview with the BBC, Martin acknowledged that even this wasn’t a panacea. There was still a lot of offsetting required when it came to flying, he said, “because even sustainable aviation fuel isn’t good enough yet.”

World's largest EV maker unveils new sodium battery electric motorbikes

Yadea, which has claimed the title of the world’s largest electric vehicle maker for seven years running, has just announced a new electric motorbike powered by the company’s innovative HuaYu sodium-ion battery technology.

Yadea has long dominated the electric two-wheeler and three-wheeler market globally, but has generally relied on both lithium-ion and lead acid batteries to power its vehicles in different markets.

The newly unveiled electric scooter uses Yadea’s recently introduced sodium battery technology, offering what the company says is outstanding performance in range, charging speed, and safety. Using the HuaYu Sodium Superfast Charging Ecosystem presented by Yadea, the battery can reach 80% charge in just 15 minutes, providing greater convenience for riders.

Yadea’s sodium battery has successfully passed more than 20 safety tests, many focusing on its resistance to fire and explosions under extreme conditions like punctures and compression.

Yadea’s new sodium battery offers an energy density of 145 Wh/kg and a lifespan of up to 1,500 cycles at room temperature, with the company rating it for a five-year useful lifespan. It also includes a three-year warranty for added assurance.

With excellent low-temperature capabilities, the battery retains over 92% of its discharge capacity at -20°C, making it well-suited for colder climates.

Sodium batteries present major advantages

Most electric vehicles used in the West, especially electric two-wheelers, rely on lithium-ion batteries for their high energy density. But sodium-ion batteries offer many benefits over traditional lithium-ion batteries.

Sodium is an abundant element on the planet and is easily accessible, unlike lithium, which is concentrated in specific regions and often expensive to extract. This abundance can make sodium-ion batteries cheaper to produce, reducing costs for EV manufacturers and potentially making electric vehicles more affordable.

Lithium mining also has environmental challenges, such as water depletion and habitat destruction. Sodium, on the other hand, can be sourced from seawater or common salts, offering a more sustainable and environmentally friendly option.

Sodium-ion batteries are less prone to overheating and thermal runaway compared to lithium-ion batteries. This makes them inherently safer for electric vehicles, reducing the risk of fires and improving consumer confidence in EV technology.

Sodium-ion batteries perform better than lithium-ion in cold climates. Lithium-ion batteries struggle with capacity retention in freezing conditions, but sodium batteries maintain efficiency, making them ideal for EVs in colder regions.

Sodium batteries still have challenges to overcome

While sodium-ion batteries are promising, they currently have a lower energy density than lithium-ion batteries, meaning they store less energy per unit of weight.

For EVs, this translates to shorter driving ranges for the same-sized battery. That’s especially important in electric two-wheelers like motorbikes and electric bicycles, which don’t have much extra space for storing bulky batteries.

However, advancements in cathode materials and battery architecture are quickly closing this gap, which Yadea has demonstrated. These sodium-ion batteries still can’t match the energy density of lithium-ion batteries, but as they continue to improve their energy density, the technology’s other major advantages provide encouraging signs for larger adoption in the industry.

Yadea’s status as a major electric motorbike maker also means that its adoption of sodium-ion battery technology could help lead the entire industry towards this battery chemistry, bringing safety and performance benefits along with it.

Last year I had the unique opportunity to visit one of Yadea’s global manufacturing sites.

CES2025 | John Deere autonomous mower promises a perfect cut, every time

At CES2025, the impressively built-out John Deere exhibit was all about automation. Autonomous job sites, autonomous farms … but it was this new, battery electric, autonomous lawn mowing robot that stole the show.

The self-driving Deere mower robot was positively dwarfed by the giant farm machinery surrounding it, but it continues to prove that humans will pack bond with anything as more than one burly-looking and grizzled man asked what its name was. (It’s Howard. I’ll fight you.)

For his part, Howard packs a 21.4 kWh battery pack that runs a suite of electric motors that includes a drive motor and three cutting blade motors spread across a 60 inch cutting deck – but it’s not the electric motors that make John Deere’s little robot mower cool, it’s the way it works.

See, instead of using “just” GPS data or “just” repeating a pre-recorded run, Howard can do something in between. The way it was explained to me, you would ride the stand-up mower around the perimeter of the area you wanted to mow, select a pattern, then hop off, fold up the platform, and let it loose. Howard mows just the way you would, leaving you to focus on edging, planting, or (let’s face it) schmoozing with the clients.

It’s exactly the sort of help landscapers are looking for.

But that should come as no surprise, of course. John Deere, perhaps more than most companies, knows its customer. “We’ve been in the turf business for 60 years — it’s a core part of Deere,” says Jahmy Hindman, chief technology officer at John Deere, explaining things beautifully. “The work that’s being done in this industry is incredibly labor intensive … they’re not just doing the mowing work. They’re doing the tree trimming, maintaining flowerbeds and all these other jobs. The mowing is table stakes, though, for them to get the business. It’s the thing they have to do in order to get the higher value work.”

Tim Lewis, lead engineer with the commercial automatous mower, told Lawn & Landscape that the industry in general has a high turnover rate as well, making it difficult to hang to people who know where one job ends and another begins. “There’s a lot of nuances it takes to do these jobs effectively,” he explains, “so “Autonomy can help with that.”

The John Deere autonomous commercial mower (there’s no snazzy alphanumeric, yet) leverages the same camera technology as other Deere autonomous machines, but on a smaller scale (since the machine has a smaller footprint). With two cameras each on the front, left, right, and rear sides of the little guy, he has a 360-degree view of the world and enough AI to lay down a pattern, avoid an obstacle, and shut off if it thinks it’s about to mow down something (read: someone) it shouldn’t.

John Deere will have Howard on display through tomorrow at CES in the LVCC’s West Hall. If you’re in town, be sure to go say hi.
