What You'll Learn
Diesel vehicles emit more harmful substances than petrol vehicles
Diesel fuel will likely be phased out in the future, as countries and car manufacturers transition to more sustainable energy sources. While there are currently no plans for a mandatory phase-out of diesel and petrol vehicles in countries like the UK, various regions have committed to banning the sale of new fossil-fuel powered cars by 2035 or earlier.
While diesel engines were once promoted as a more environmentally friendly alternative due to their lower carbon dioxide (CO2) emissions, the focus on CO2 led governments to overlook other toxic emissions. The Volkswagen scandal, known as Dieselgate, further brought to light the issues with toxic emissions from diesel engines, as it was found that their vehicles emitted up to 40 times more nitrogen oxides than the set standards.
To address the emissions gap, diesel engine manufacturers have adopted technologies like particulate filters. However, these filters can clog in urban driving conditions and require regular maintenance. Additionally, diesel engines require more driver input for emissions regulation, as they need a urea mixture added to the engine. In contrast, petrol emissions systems are self-regulating.
Despite the higher emissions of harmful substances, diesel vehicles offer better fuel economy, making them a more cost-effective option for high-mileage drivers. Nevertheless, the transition away from diesel fuel and the increasing demand for electric vehicles will likely lead to a gradual phase-out of diesel cars over time.

The UK will ban the sale of new diesel cars by 2035
Diesel fuel is a fossil fuel that powers vehicles, including cars, vans, lorries, and buses. Several countries and cities worldwide have pledged to phase out the sale of new fossil-fuel-powered vehicles, including diesel, and encourage the use of alternative forms of transportation.
In the UK, the government has announced plans to ban the sale of new petrol and diesel cars from 2035, with the original target date being 2030. This ban is part of a "green industrial revolution," aiming to create a low-carbon economy and millions of new jobs. The delay from 2030 to 2035 was made by Prime Minister Rishi Sunak to ease the burden on motorists during the cost-of-living crisis.
From 2035 onwards, new car buyers in the UK will only be able to choose from vehicles that produce zero emissions, primarily battery-electric vehicles, but other options like hydrogen fuel cell models may also be available. While there are currently no plans for a mandatory replacement of existing petrol and diesel vehicles with electric ones, it is expected that internal combustion engine (ICE) cars will gradually disappear from the roads as the ban on their sales takes effect.
The phase-out of diesel and the transition to electric vehicles is driven by environmental concerns. Diesel vehicles produce higher levels of nitrogen oxides and particulate matter, contributing to an increased risk of respiratory illnesses, lung cancer, heart disease, and other conditions. The UK has approximately 30 million petrol and diesel cars, and this transition is expected to be gradual, with a reduction in demand for diesel fuel over time.
While diesel vehicles are being phased out in the UK and other countries, there is still a demand for diesel cars among high-mileage drivers due to their better fuel economy. Car manufacturers will likely continue to meet this demand, and diesel cars may remain in use beyond 2035, but their numbers are expected to decrease significantly.

India has pledged to phase out the sale of new diesel vehicles by 2040
India has been facing an air pollution crisis that is responsible for 1.2 million deaths per year and costs the economy an estimated 3% of its GDP. In a bid to curb this growing threat, the Energy Transition Advisory Committee has recommended banning all diesel vehicles by 2027 in cities with a pollution density of more than one million people. The Indian government has also announced that it wants to sell only electric cars within the next 13 years.
In November 2021, the Indian government joined 30 other national governments and six major automakers in pledging to phase out the sale of all new petrol and diesel vehicles by 2040 worldwide, and by 2035 in leading markets. This pledge was made at the 2021 United Nations Climate Change Conference held in Glasgow, where multiple governments and companies signed a non-legally-binding declaration to accelerate the transition to zero-emission cars and vans.
While this pledge is a positive step towards reducing air pollution and tackling climate change, it will be challenging to implement. Diesel-powered vehicles are widely used in India, particularly in trucks and buses, and have cheaper operating expenses and better performance compared to petrol vehicles. A sudden ban on diesel vehicles could lead to severe disruptions and financial problems for many people.
To achieve the goal of phasing out diesel vehicles by 2040, the Indian government and automakers will need to work together to promote the adoption of electric vehicles and develop the necessary infrastructure. This may include providing incentives for the purchase of electric vehicles, investing in charging stations, and ensuring a stable supply of electricity to meet the increased demand. It will also be important to address the concerns of those who rely on diesel vehicles for their livelihoods, such as offering support for the transition to electric alternatives.

Diesel fuel is evolving to become more sustainable
Diesel fuel is indeed being phased out in some places, with many countries and cities committing to banning the sale of diesel-powered vehicles. However, diesel fuel is also evolving to become more sustainable.
Diesel has been the go-to fuel for moving entire industries, especially for heavy-duty vehicles and equipment requiring high power and endurance. Diesel vehicles have nearly doubled their fuel efficiency rates in the last decade. Diesel is also a flexible fuel, with the ability to be used with a wide range of engines and equipment.
However, diesel vehicles have faced scrutiny due to their emissions, particularly the Volkswagen scandal ("Dieselgate") in 2015, which revealed that diesel engines were emitting far more nitrogen oxides (NOx) than previously thought. This, along with concerns about other emissions like soot and sulphur, has led to a push for cleaner diesel technology. Renewable diesel, a type of biofuel made from vegetable oils and animal fats, is one such alternative that reduces greenhouse gas emissions while maintaining fuel economy and performance.
While the demand for diesel engines remains high, with millions of diesel vehicles on roads worldwide, the future of diesel is about balance and diversification. As emission regulations tighten, diesel manufacturers are working to improve fuel efficiency and sustainability.
The transition to cleaner energy sources and the emergence of electric vehicles will likely reduce the demand for diesel fuel over time. However, diesel fuel is not expected to disappear anytime soon, especially with the development of cleaner diesel powertrain technology.

Diesel locomotives are being replaced with alternatives
Diesel locomotives are indeed being phased out in favour of alternative energy sources. This is part of a broader shift away from fossil fuels and towards electrification. In November 2021, the Indian government joined 30 other national governments in pledging to phase out the sale of all new petrol and diesel vehicles by 2040, with the aim of achieving this by 2035 in leading markets.
This shift is also occurring at the city level, with some local governments implementing measures to partially or entirely phase out fossil fuel vehicles. Cities like Brussels, Madrid, and Paris plan to reject Euro 6 diesel vehicles from their urban centres due to air quality concerns. The UK is also set to ban the sale of new petrol and diesel cars from 2030 onwards, and while classic cars will be exempt, demand for petrol and diesel will likely decrease.
Germany is another country pushing to replace diesel locomotives with alternatives. This is partly due to legal challenges brought by Environmental Action Germany (DUH), which has resulted in local diesel restrictions. Alternatives to diesel locomotives include battery electric multiple units, hydrogen fuel trains, and overhead wire electrification. While electric locomotives were introduced before diesel, they are now seen as superior due to their increased power, reduced weight, lower emissions, and quieter operation.
However, the transition to electric locomotives is not without its challenges. Electrifying tracks can be extremely costly, especially in countries like the US with extensive railroad networks. Additionally, electric locomotives may not be suitable for all routes, and diesel locomotives can serve as a backup solution in such cases.
In summary, diesel locomotives are being replaced with alternatives as part of a broader shift away from fossil fuels. While electric locomotives offer significant advantages, the transition is gradual due to the high costs and infrastructure changes involved.
