Environmental impact of oil tanker collision depends on at least three things
The crash involving a cargo ship and oil tanker off the East Yorkshire coast is bad news for the sea, fish and air in the area. What we don’t know yet is quite how bad it will be.
That depends on a few things – but the speed of the collision, clouds of filthy black smoke from the fires and the leaked fuel are certainly worrying.
Firstly, it matters what was on board those two massive vessels.
Follow live: Jet fuel spilling into sea after tanker collision
Analytics firm Vortexa estimates the 183m-long tanker was carrying about 130,000 barrels of jet fuel (kerosene), which is now leaking into the sea.
Jet fuel is not as sticky or viscous as heavier types of oil, thankfully, so it’s less likely to clog the feathers and fur of birds and seals. It can also be broken down by natural bacteria.
But it can still poison fish and kill animals and plants on the shoreline if it makes its way into the soil there.
The Marine Conservation Society has pointed out the site in the Humber estuary is close to some protected areas and is important for seabirds and harbour porpoises.
And both ships will have been powered by a dirtier, heavier kind of oil – likely marine gas oil or heavy fuel oil, though we don’t know the details yet.

Cheap, thick and tar-like, it can smother animals and is very dangerous if they consume it, and is extremely difficult to clean up. Let’s hope this isn’t creeping around the North Sea already.
We don’t know how much of either the jet fuel or the oil powering the ships has leaked, or how much will be burned off in the violent fires – which themselves are ploughing black smoke and filthy air pollution into the surrounding atmosphere.
And we don’t know for sure what was on the Solong cargo ship and if, or what, will go into the sea.
Cargo ship ‘had sodium cyanide on board’
It was carrying 15 containers of sodium cyanide among other cargo, according to a report from maritime data provider Lloyd’s List Intelligence.
The container vessel was also transporting an unknown quantity of alcohol, said the casualty report – an assessment of incidents at sea – citing a message from the local coastguard.
Plastic takes hundreds of years to break down, and potentially can choke or trap animals.
Many of us have seen that uncomfortable viral video of a turtle having a straw yanked out of its nose. Previous accidents on cargo ships have seen plastic Lego pieces wash up in Cornwall 25 years later.

Secondly, the impact depends on the sea and weather conditions around it.
Things like the wind and currents affect how an oil spill spreads in the sea. Scientists can draw up computer models to simulate how the oil could behave.
Thirdly, it matters how quickly this is all tackled and then cleaned up, if necessary, and if it can be.
Usually the slower the response, the worse the impact.
The coastguard has said the incident “remains ongoing” and it has started assessing the “likely counter pollution response” that will be required.
Such a response might need the help of numerous public bodies: the government environment department, the transport department, the Environment Agency and the Maritime and Coastguard Agency.
So for now the best we can hope for – aside from the welfare of the people involved – is that not all the oil is spilled or burnt, that conditions are calm and that rescuers and those cleaning up can work swiftly.
UK drivers are “confused” by the country’s electric car transition, ministers are being warned.
Although most drivers are not hostile towards electric vehicles (EVs), many are confused about what changes are coming and when, according to new research from the AA.
In a survey of more than 14,000 AA members, 7% thought the government was banning the sale of used petrol and diesel cars.
Around a third thought manual EVs exist, despite them all being automatic.
More than one in five said they would never buy an EV.
The government’s plan for increasing the number of electric vehicles being driven in the UK focuses heavily on increasing the supply of the vehicles.

What you can do to reach net zero
In 2024, at least 22% of new cars and 10% of new vans sold by each manufacturer in the UK had to be zero-emission, which generally means pure electric.
Each year, those percentages will rise, reaching 80% of new cars and 70% of new vans in 2030.
Manufacturers will face fines of £15,000 per vehicle if electric vehicle sales fall short of 28% of total production this year.

By 2035, all new cars and vans will be required to be fully zero emission, according to the Department for Transport.
Second-hand diesel and petrol cars will still be allowed to be sold after this date, and their fuel will still be available.
There are more EVs – but will people buy them?
In February, 25% of new cars were powered purely by battery and in January, they made up 21% of all new cars registered in the UK.
But despite the growth of electric sales, manufacturers continue to warn that the market will not support the growth required to hit government EV targets, and called for consumer incentives and the extension of tax breaks.
The AA suggested the government’s plan focuses on “supply but does little to encourage demand for EVs”.
It called on ministers to co-ordinate a public awareness campaign alongside the motoring industry which directly targets drivers who doubt the viability of EVs.
“Our message to government is more needs to be done to make EVs accessible for everyone,” said Jakob Pfaudler, AA chief executive.
Which? head of consumer rights Sue Davis said: “When it comes to making sustainable choices such as switching to an electric car, our research shows that people are often held back by high costs, complex choices or uncertainty.
“The government needs to provide the right information on electric vehicles and other sustainable choices so that people have the confidence to switch.”
A Department for Transport spokesperson said: “We’re investing over £2.3bn to help industry and consumers make a supported switch to EVs.
“This includes installing a public charge point every 28 minutes, keeping EV incentives in the company car tax regime to 2030, and extending 100% first-year allowances for zero-emission cars for another year.
“Second-hand EVs are also becoming cheaper than ever, with one in three available under £20,000 and 21 brand new models available for less than £30,000.
“We’re seeing growing consumer confidence as a result.”
