Ship Scrubbers Have Caused Major Environmental Damage

The adoption of ship scrubbers—technology meant to clean up dirty fuel—has caused a surge in heavy metal pollution.

Lina Zeldovich, writing for Hakai Magazine – Coastal Scienec and Societies reports:  “In early 2020, people in port cities around the world started breathing a little easier thanks to new regulations from the International Maritime Organization (IMO)—the overseer of international shipping—that restricted how much sulfur oxide pollution ships could have in their exhaust. Sulfur oxides, also known as SOX gases, can trigger a rash of ill effects, including heart and lung diseases and asthma. Worldwide, sulfur pollution is linked to some 400,000 premature deaths and 14 million new childhood asthma cases each year.

Shipping companies largely complied with the IMO’s new rule. But one of the prime tools in this cleanup effort—devices known as ship scrubbers—had an unfortunate side effect. While the technology has successfully diverted boatloads of pollutants from the air, it has also sent a steady flow of heavy metals into the sea, contaminating marine life and causing millions of dollars worth of damage.

The problem wasn’t negligence or oversight, according to Erik Nøklebye, the CEO of the Swedish shipping company Wallenius Lines, but rather an example of an “imperfect innovation solution.” When the IMO issued its new regulations, says Nøklebye, shipping companies essentially had two options: switch from the default heavy fuel oil to more expensive low-sulfur fuel, or install a ship scrubber—a device that sprays ocean water onto exhaust gases before they leave the engine, capturing the harmful SOX gases as a sulfuric acid solution.”

Surprising Downsides to Planting Trillions of Trees

New research has found that we have to be very careful of the potetential unseen consequences of our actions:

“On November 11, 2019, volunteers planted 11 million trees in Turkey as part of a government-backed initiative called Breath for the Future. In one northern city, the tree-planting campaign set the Guinness World Record for the most saplings planted in one hour in a single location: 303,150.

“By planting millions of young trees, the nation is working to foster a new, lush green Turkey,” Turkey’s president, Recep Tayyip Erdoğan, said when he kicked off the project in Ankara.

Less than three months later, up to 90 percent of the saplings were dead, the Guardian reported. The trees were planted at the wrong time and there wasn’t enough rainfall to support the saplings, the head of the country’s agriculture and forestry trade union told the paper…

Forests are, of course, good for the planet. And they do absorb loads of greenhouse gases, making them an important bulwark against rising temperatures. But headline-grabbing campaigns focused solely on planting trees can harm both people and ecosystems by focusing more on the goal itself than on the purpose behind it — and distracting us from the hard work of reducing emissions. The tough reality, as Holl puts it, is that “we’re not going to plant our way out of climate change.”

New Hydrogen-electric Light Aircraft Engines

ZeroAvia has received a conditional order from Maritime Energy Heli Air Services (MEHAIR), for a maximum of 20 ZA600 hydrogen-electric engines.

These engines have been under development with Zero Avia for a long time and their current plan involves their aim to have the engine certified by the end of 2025. Along with working to develop the engine itself, the company has also been working with the UK’s CAA, plus other regulators, to make sure that the engine is certified across the globe. The order that MEHAIR made, brings the total number of engine pre-orders which ZeroAvia has received up to 2,000.

Cessna C208 Caravan of the type to be converted to hydrogen-electric engines

The 20 ZA600 engines will be retrofitted to MEHAIR’s fleet of 10 Cessana Caravan aircrafts and in order to do this MEHAIR will begin looking into options for financing this development. Along with supplying the engine, ZeroAvia will also work together with MEHAIR to create a fuel supply across India, to enable the operator’s services.

MEHAIR has ordered the engines as the company has stated their plans and aims of creating a system of sub-regional routes throughout India. The company aims for these routes to be accessible for both amphibian and wheeled aircraft. These designs have been approved by India, who will use these aircrafts to its advantage in its aim to use hydrogen as a pathway towards it clean energy future. The main focus for India’s plan will be on the hard-to-abate sectors such as aviation, with the overall goal for this plan being to reach Net Zero by 2070. Starting this journey, India has the preliminary aim to be producing five million metric tons of hydrogen every year, by 2030.

In the past ZeroAvia has had success with hydrogen-powered technology and the company recorded its first flight in 2023, they have also entered several other partnerships with other countries, continuously expanding and growing their business.

Emirates Declaration on Sustainable Agriculture, Resilient Food Systems and Climate Action

Launched at COP28 in Dubai, the Emirates Declaration on Sustainable Agriculture, Resilient Food Systems and Climate Action reaffirms existing international commitments to halt climate change and nature loss while building in more resilience. It outlines how bringing these agendas together will be crucial to ensuring food security in the decades to come.

Representatives of those signed up to the Declaration will meet at a roundtable this weekend, within the annual UN-led climate conference, to make connections that should enable collaborative delivery.

The Declaration covers issues including:

  • Adapting food systems to climate change that is already ‘baked in’, with a focus on the specific needs of the most-affected groups including smallholder farmers and Indigenous groups
  • Helping these groups maintain their livelihoods
  • Enhancing early warning systems
  • Enhancing water management in agriculture, which accounts for more than 70% of global freshwater use each year
  • Protecting and restoring soils and ecosystem
  • Reducing food loss and waste, which is accountable for at least 8% of global annual emissions
  • Promoting more sustainable aquaculture
  • Encouraging changes in consumption, with a focus on the Global North
  • Ensuring and improving access to nutrition, with a focus on the Global South

Fatal Flaw with Vertical Farming

In June 2022, a vast new vertical farm opened on the outskirts of the town Bedford, UK. At a swanky opening event, members of the UK Parliament heard that the gleaming facility would one day produce 20 million plants annually. It was the latest opening for Infarm, a European vertical farming company that had raised over $600 million in venture capital funding, promising a future where vegetables are grown in high-tech warehouses stacked with LED lights rather than in open fields or greenhouses.

But now the future of the Bedford farm looks less than gleaming. On November 29, Infarm’s founders emailed its workforce to announce they were laying off “around 500 employees”—more than half of the workforce. The email detailed the firm’s plans to downsize its operations in the UK, France, and the Netherlands, and concentrate on countries where it had stronger links to retailers and a higher chance of eventually turning a profit. In September, Infarm had already laid off 50 employees, citing a need to reduce operating costs and focus on profitability.

Just six months ago, the vibe from Europe’s biggest vertical farm company was unrelentingly optimistic, so what changed? According to Cindy van Rijswick, a strategist at the Dutch research firm RaboResearch, several pressures that have always existed for vertical farms have really come to a head in 2022. For starters, the industry is extremely vulnerable to increases in electricity prices. Powering all of those plant-growing LEDs uses a lot of electricity, and between December 2020 and July 2022 consumer energy prices in the EU went up by nearly 58 percent. Eighteen months ago, European vertical farms might have spent around 25 percent of their operational costs on electricity, but that might have gone up to around 40 percent, estimates van Rijswick.

At the same time, investors are starting to tighten their belts and look for faster routes to profitability. Vertical farms are expensive to build compared with conventional outdoor farms. AppHarvest—a US-based firm that builds high-tech greenhouses—has struggled to find enough cash to fund its ongoing operations despite going public in 2021. In its latest quarterly report the company said there is “substantial doubt” about its ability to continue into the future.

The poor global financial outlook is also putting pressure on consumers. Most vertical farms grow herbs, shoots, and other leafy salad vegetables. Leafy greens are the industry’s go-to produce because they grow quickly under LEDs and have a short shelf life and premium price point. But with inflation high, consumers might prefer to forgo expensive vertically farmed herbs for something a little more budget-friendly. That’s particularly true for European vertical farms. “The European market is a difficult place for vertical farming because there’s so much competition from crops that are grown in fields or greenhouses,” says van Rijswick.

Vertical farms might stand a better chance of surviving if they look further afield, to countries where energy is cheap and growing crops outside is difficult. One obvious place is the Middle East. Gulf Cooperation Council countries—a group made up of Saudi Arabia, Bahrain, Kuwait, Oman, Qatar, and the United Arab Emirates—import around 85 percent of all their food and 56 percent of their vegetables. “When choosing new markets to expand to and establish a farm, we are going to look to places that have an increasing need for food production and food security,” Infarm founder Erez Galonska told the Vertical Farming Congress in Abu Dhabi on December 14. One of the world’s largest vertical farms opened earlier this year in Dubai. The facility is nearly three times the size of Infarm’s Bedford growing center and supplies leafy greens for the Emirates airline and local stores.

Largest Vertical Farm: Dubai

Crop One Holdings and Emirates Flight Catering announced this week they opened Emirates Crop One, what they say is “the world’s largest vertical farm.”

The over 330,000-square-foot facility is located in Dubai, United Arab Emirates near Al Maktoum International Airport at Dubai World Central. It has the capacity to produce over 2 million pounds of leafy greens annually.

The facility got its start in 2018 when Crop One, an indoor vertical farming company, and Emirates Flight, the airline Emirates catering arm, signed a $40 million joint venture to build Emirates Crop One. AgFunder reported the $40 million was a majority debt funded.

Dubbed ECO 1, the farm uses 95% less water than field-grown produce and is guaranteed an output of three tons per day, according to the companies. Passengers on Emirates and other airlines will be able to eat the leafy greens, which include lettuces, arugula, mixed salad greens and spinach on their flights starting this month.

Those local to the United Arab Emirates will be able to buy the produce at stores under the Bustanica brand. The greens require no pre-washing and are grown without pesticides, herbicides or chemicals.
