The phase-out of diesel fuel has been a topic of discussion for several years, with a growing number of cities and countries taking steps to restrict or ban its use. Diesel-powered vehicles have been associated with high levels of pollution, particularly in urban areas, due to the emission of nitrogen oxides, particulate matter, and microscopic soot particles that can have significant impacts on human health and the environment. In response to these concerns, cities like Paris, Rome, Madrid, Athens, and Mexico City have announced plans to ban diesel cars by 2024 or 2025. Car companies such as Fiat Chrysler, Toyota, Honda, and Ford have also announced plans to phase out diesel engines from their passenger cars due to declining demand, rising production costs, and a shift towards electric vehicles. While diesel fuel was once promoted as a more fuel-efficient and environmentally friendly alternative, the focus has now shifted towards reducing air pollution and encouraging the development and adoption of cleaner energy sources for transportation.

What You'll Learn
Environmental pressures and consumer confusion
Diesel fuel is facing environmental pressures and consumer confusion, which are driving its "slow death".
Environmental Pressures
Once promoted by governments and the car industry as a cheaper way to save the planet, diesel fuel is now facing scrutiny due to its environmental impact. In the 1980s, Germany, with the efforts of environmentalist Jürgen Resch, instituted regulations to lower the sulfur content of diesel fuels and established low-emission zones in German cities, which were eventually adopted by the EU. However, it was later discovered that diesel exhausts release nitrogen oxides and dioxides (NOx) and particulate matter (PM), which contribute significantly to pollution in cities and have detrimental health impacts. As a result, cities like Paris, Rome, Madrid, Athens, and Mexico City have announced plans to ban diesel cars by 2024 or 2025. German cities, such as Hamburg, have also approved bans on older diesel vehicles to reduce air pollution, and similar measures are expected to spread to other cities. These environmental concerns have led to increased taxes and charges for diesel vehicles, further reducing their appeal.
Consumer Confusion
The decline in diesel's popularity is also influenced by consumer confusion and a lack of enthusiasm for diesel vehicles. Marketing consultant Dennis Keene notes that consumers don't fully understand diesel and are hesitant to purchase diesel cars. The Volkswagen emissions scandal, where cars produced higher levels of NOx on the road than in laboratory tests, further damaged consumer trust. Additionally, the focus on bringing down the cost of electric vehicles and the development of hybrid and all-electric cars provide consumers with more attractive and environmentally friendly alternatives. As a result, the demand for diesel cars has decreased, impacting both the new and second-hand markets.

The Volkswagen emissions scandal
Volkswagen deployed this software in about 11 million cars worldwide, including 500,000 in the United States, from model years 2009 to 2015. The scandal was first uncovered in 2013 when the International Council on Clean Transportation (ICCT) commissioned the West Virginia University Center for Alternative Fuels Engines and Emissions (WVU CAFEE) to test the on-road emissions of diesel cars sold in the US. An environmental policy group further exposed the fraud in 2015, revealing that Volkswagen's "'clean diesel'" cars produced up to 150 times the pollutant levels of gasoline-powered models.
As a result of the scandal, Volkswagen faced significant consequences and financial penalties. In April 2016, the company announced plans to spend €16.2 billion (US$18.32 billion) related to the scandal. In June 2016, Volkswagen agreed to pay up to $14.7 billion to settle civil charges in the United States, including buybacks, lease terminations, and compensation for consumers. In January 2017, Volkswagen pleaded guilty to criminal charges and acknowledged that its management had instructed engineers to develop the defeat devices to conceal the true emissions levels of its diesel models. As of June 2020, the scandal had cost Volkswagen $33.3 billion in fines, penalties, financial settlements, and buyback costs.

Government incentives for diesel
Diesel fuel was once promoted by governments and the car industry as a cheaper, more fuel-efficient, and environmentally friendly alternative to petrol. In the 1990s, diesel passenger cars gained popularity in Europe due to advancements in engine technology, and many drivers switched to diesel, which was touted as emitting less CO2 than petrol. To encourage the use of diesel, governments offered various incentives such as tax breaks and duty cuts. For example, in the UK, Gordon Brown, the then-chancellor of the Labour government, cut fuel duty on diesel vehicles in 2001.
However, in recent years, the tide has turned against diesel as the health and environmental impacts of diesel emissions have come to light. Cities like Paris have introduced restrictions on diesel-run cars, with plans to phase out diesel entirely by 2025. The resale value of diesel cars has also declined due to decreasing demand and the push for cleaner alternatives.
Despite the backlash against diesel, some governments continue to offer incentives for diesel-powered vehicles, particularly in the form of tax credits. In the United States, diesel-powered car buyers can qualify for federal tax credits as diesel engines are generally more fuel-efficient and can run on cleaner blends of diesel fuel. The specific incentives vary across different states. For example, Arizona offers a $75 tax credit for installing an EV charging outlet, while California offers rebates of up to $2,500 for purchasing an EV or plug-in hybrid through the Clean Vehicle Rebate Project (CVRP). Colorado provides grants of up to $5,000 for purchasing electric vehicles.
The federal government also provides tax credits for specific models, such as certain Volkswagen diesel models, which can receive a tax credit of up to $1,700. However, these tax credits are typically higher for alternative fuel vehicles, such as the Honda Civic GX, which runs on compressed natural gas (CNG) and receives a $4,000 tax credit. Additionally, the Diesel Emissions Reduction Act (DERA) Program offers grants and rebates to upgrade older diesel engines to cleaner and zero-emission solutions.
While the focus has shifted towards electric and hybrid vehicles, some of the existing incentive programs for diesel vehicles are still in place, although they may be phased out gradually.

Bans on diesel in major cities
While diesel fuel has not been banned in Europe, major cities across the world have implemented or are considering implementing bans on diesel-powered vehicles. These cities include Paris, Mexico City, Madrid, Athens, London, Copenhagen, and Stockholm.
In 2017, Paris introduced a system of coloured stickers to classify car types and emission levels. Diesel-run cars made before 2000 are not allowed on the roads inside the French capital, and diesel cars built between 2000 and 2010 could face tighter restrictions as the mayor, Anne Hidalgo, tries to phase out diesel entirely by 2025. Paris has also implemented a car-free zone along the Seine River and closed the Champs-Élysées to traffic once a month.
The mayors of Mexico City, Madrid, Athens, and Paris announced plans in 2016 to ban diesel cars and vans from their roads by 2025. This initiative, led by Anne Hidalgo, aimed to tackle air pollution and the health problems and deaths caused by it. The mayor of Mexico City, Miguel Ángel Mancera, said that increasing investments in public transport and promoting electric vehicles would help clean the city's air and reduce greenhouse gas emissions.
In the UK, campaigners have urged London's mayor, Sadiq Khan, to commit to phasing out diesel vehicles from the city by 2025 and creating new clean air zones in all of the UK's major towns and cities. Khan has proposed an expansion of the planned Ultra-Low Emission Zone in central London.
Other cities that are considering banning diesel vehicles include Copenhagen and Stockholm. Copenhagen will test extensive zero-emission zones from 2023, which will effectively ban diesel cars. Stockholm has approved a regulation banning petrol and diesel cars from entering the city centre starting in December 2024 to reduce pollution and emissions.
The push to ban diesel vehicles in major cities is driven by concerns about air quality and the health impacts of diesel emissions, which include nitrogen oxides (NOx), particulate matter (PM), and soot. These pollutants can contribute to cardiovascular illness and death, with the World Health Organization (WHO) linking around three million deaths every year to exposure to outdoor air pollution.
The shift away from diesel is also influenced by the development of alternative technologies, such as electric, hybrid, and plug-in vehicles, which are becoming more affordable and attractive to consumers.

The future of diesel cars
The decline in the popularity of diesel cars can be attributed to a variety of factors, including environmental concerns, consumer confusion, and the rising cost of diesel fuel. Environmental groups have raised concerns about the impact of nitrogen oxides and particulate matter (PM) on human health, with studies showing that these emissions from diesel engines contribute significantly to pollution in cities and can cause respiratory issues.
In response to these concerns, many cities around the world have taken steps to reduce the use of diesel cars. Paris, for example, has introduced a system of coloured stickers to classify car types and emission levels, with plans to phase out diesel entirely by 2025. Other cities, such as Rome, Madrid, Athens, and Mexico City, have also announced similar bans on diesel cars by 2025. German cities have also started to ban older diesel vehicles from busy downtown areas, with Hamburg leading the way.
The decline in the demand for diesel cars has also affected the second-hand market, with the value of used diesel models declining. This is due to the restrictions on diesel cars entering city centres and the lack of enthusiasm for diesel engines among consumers. As a result, car companies are shifting their focus towards hybrid, plug-in, and all-electric vehicles, with the cost of these technologies becoming more affordable.
While diesel cars may have been popular in the past for their fuel efficiency and lower carbon dioxide emissions, the tide is turning against them. The future of diesel cars looks increasingly uncertain as cities and countries move towards cleaner and more sustainable transport options.
