Shipping's Climate Impact: Will Green Ships Lead the Way?

In the bustling harbor of Copenhagen, the world recently witnessed the arrival of Laura Maersk, an impressive container ship. While she may not be a visiting dignitary, her significance goes beyond her colossal stature. Laura Maersk is a prime example of the global shipping industry's efforts to combat its role in the planet's warming.

Commissioned by Maersk, this remarkable ship boasts a special engine capable of burning green methanol as an alternative to conventional fossil fuels. By making this shift, Laura Maersk singlehandedly reduces her daily greenhouse gas emissions by a staggering 100 tons, equivalent to the emissions of 8,000 cars.

The impact of global shipping on our climate cannot be overstated. This industry is responsible for nearly 3% of worldwide greenhouse gas emissions, an amount matching the annual emissions of the aviation sector.

Finding solutions to limit these emissions is challenging. Some ships are revisiting age-old techniques, like harnessing wind power. However, for a vessel to circumnavigate the globe, a more reliable and powerful energy source is necessary, as ships can't frequently recharge from batteries and electrical grids. They require a portable, clean fuel.

Laura Maersk's pioneering voyage with a green methanol engine is a significant step in addressing the shipping sector's climate contribution. However, it also underscores the vast journey that lies ahead. While about 125 methanol-burning ships are currently on order from companies like Maersk, this is just a fraction of the 50,000+ cargo ships traversing our oceans daily, transporting 90% of the world's goods.

The market for green methanol is still in its infancy, and it remains uncertain if this new fuel will be produced in sufficient quantities and at the right price to power the vast global fleet.

Surprisingly, shipping remains an efficient method of transportation. Shipping goods halfway across the world via container ship generates significantly fewer greenhouse gas emissions compared to trucking them across a single country.

However, this efficiency has come at an environmental cost. Ships burning fossil fuels not only affect our atmosphere but also release pollutants, negatively impacting the health of communities near ports.

During the COVID-19 pandemic, supply chain bottlenecks led to the piling up of ships outside the Port of Los Angeles, creating pollution equivalent to nearly 100,000 big rigs per day. Teresa Bui, the policy director for climate at Pacific Environment, emphasizes the decades of underregulation in the shipping industry.

Some shipping companies attempted to cut emissions by using liquefied natural gas, but many argue that relying on another fossil fuel is not the right direction. For Maersk and several other industry players, greener fuels like methanol, ammonia, and hydrogen offer the most promising path. Maersk's goal is to achieve zero carbon emissions by 2040, and they are investing significantly in cleaner fuels.

Transitioning to methanol requires new ship designs or retrofitting old ones with different engines and fuel storage systems. Ports worldwide must install the necessary infrastructure for fueling these vessels.

Crucially, the production of green methanol needs to grow. Currently, most methanol is produced from coal, oil, or natural gas. Green methanol can be made more sustainably using renewable energy and captured carbon. However, its production remains limited. While Maersk commits to sustainably produced methanol, it's essential for the entire industry to follow suit.

Ahmed El-Hoshy, CEO of OCI Global, points out that the production of green methanol remains at an early stage. Technology and financing are crucial to scaling up these projects. Long-term contracts for green fuel are also needed, as it can be up to three to five times more expensive than conventional fuel.

Maersk has already established partnerships with green fuel providers like OCI and European Energy, which is building the world's largest plant for methanol production using renewable electricity. Companies like Amazon and Volvo are willing to pay more for greener fuel transport, reducing their carbon footprint.

However, many companies are hesitant to embrace these greener technologies, citing cost concerns. A key missing element, according to experts, is regulation that levels the playing field for companies working to reduce emissions.

The European Union and the United States have started implementing rules to encourage decarbonization and green fuel use in shipping. The International Maritime Organization, a United Nations body, has set an ambitious target to eliminate greenhouse gas emissions from the global shipping industry by around 2050.

Nations are working on a legal framework to regulate emissions, but debates continue regarding the type of regulation and its impact on the industry's economics. Some believe that strict regulation could increase shipping costs and harm economies, while proponents argue it's essential to support cleaner practices and provide industry direction.

While green methanol may not be the ultimate solution, it signifies a pivotal shift in the sector. Maersk acknowledges that the maritime industry is unlikely to be predominantly powered by methanol. However, they emphasize the importance of transitioning to greener technologies as they become available.

In the end, a comprehensive and global approach to regulating emissions and promoting cleaner fuels is the key to a sustainable shipping industry. The transformation is underway, and the world is watching closely.

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering MagR expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the MagR gene responded to magnetic fields only in the presence of light, with Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns The World Beekeeping Awards will not grant a prize for honey next year due to the “inability” to thoroughly test honey for adulteration. The announcement comes amid the rise of honey fraud in the EU, where a 2023 investigation found that 46% of 147 honey samples tested were likely contaminated with low-cost plant syrups. Apimondia, the International Federation of Beekeepers’ Associations, organizes the event at its Congress, whose 49th edition will be held in Copenhagen, Denmark, in September 2025. The conference brings together beekeepers, scientists and other stakeholders. “We will celebrate honey in many ways at the Congress, but honey will no longer be a category, and thus, there will be no honey judging in the World Beekeeping Awards. The lessons learned from Canada 2019 and Chile 2023 were that adequate testing was impossible if we are to award winning honey at the Con...

Start the New Year Humming Like a Bee

Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

The Essential Role of Bees in Our Ecosystem and the Challenges They Face

The Essential Role of Bees in Our Ecosystem and the Challenges They Face Bees have been an integral part of our ecosystem and human agriculture for over four centuries, primarily utilized for their honey in the early days. Now, they are recognized more for their critical role in pollination, which directly impacts a vast majority of the food we consume. Mark Lilly, a prominent beekeeper, emphasizes that without bees' pollination efforts, a significant portion of our diet would be at risk. However, bees face numerous threats, including varroa mites and, in specific regions like West Virginia, black bears. These challenges necessitate concerted efforts for preservation and protection. Frequently Asked Questions (FAQs) Q1: Why are bees so important to the ecosystem? A1: Bees are crucial for pollinating plants, which is necessary for the production of fruits, vegetables, and nuts.

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles As the number of pets in South Korea steadily increases, pet owners face a growing dilemma due to the limited number of pet cemeteries across the country. Under the current legal framework, pet remains are classified as household waste, requiring specific disposal methods that are neither convenient nor easily accessible for all citizens. The imbalance between the rising pet population—over 5.52 million households with pets by the end of 2022—and the mere 70 registered pet cemeteries has led to significant challenges. This shortage is particularly evident in regions like Jeju Island, where pet owners must undergo arduous journeys to the mainland to ensure their pets receive proper burials. The root cause of this shortage lies in the strict regulations governing the establishment of pet cemeteries. These facilities, which must include crematoriums, face numerous restrictions, such as proximity to resident...

Climate Crisis Claims Glacier's Vital Climate Data Archive

Climate Crisis Claims Glacier's Vital Climate Data Archive A recent study published in Nature Geoscience reveals a distressing consequence of global warming: the irreversible loss of valuable climate data stored in alpine glaciers. The research, conducted by a team led by Margit Schwikowski from the Paul Scherrer Institute (PSI), underscores the alarming rate at which glaciers are melting and highlights the implications for climate research. The study focuses on the Corbassière glacier at Grand Combin in Switzerland, where ice cores drilled in 2018 and 2020 were intended to serve as vital climate archives. However, comparing the two sets of ice cores reveals a grim reality—global warming has rendered the glacier unsuitable as a reliable climate archive. Glaciers, renowned as climate archives, encapsulate valuable information about past climatic conditions and atmospheric compositions. The fluctuating concentrations of trace substances in ice layers provide insights into historica...

German election: Climate and environment take a back seat

German election: Climate and environment take a back seat When the coalition government comprising the center-left Social Democratic Party (SPD) , Greens and neoliberal Free Democratic Party (FDP) emerged after the last German federal election in the fall of 2021, then-incoming Chancellor Olaf Scholz (SPD) did not object to being called the "climate chancellor." That was no surprise: the climate crisis had been a top issue during the election campaign. The new government made the fight against climate change a task for the Economy Ministry and appointed Vice Chancellor Robert Habeck from the Greens as its head. Three and a half years later, campaign speeches barely mention climate protection. The dominant issues are how to curb irregular immigration and how to boost Germany's sluggish economy. Skeptical view of renewable energy The head of the center-right Christian Democratic Union (CDU) , Friedrich Merz ...
