How to make cars more eco-friendly? (3 ways)

The article will explain how to make cars more eco-friendly. Three narratives will be shed light on that will include the manufacturers, governments, and personal levels. 

How to make cars more eco-friendly?

The transportation sector, specifically the automotive industry, has a substantial impact on global carbon emissions. Cars, trucks, and buses contribute approximately 20% of the world’s carbon dioxide emissions, making a significant contribution to climate change. 

As a result, there is a pressing need to reduce the carbon footprint of vehicles by making them more environmentally friendly. This essay will explore several strategies to achieve this objective.

What can car manufacturers do to make cars more efficient?

Car manufacturers can play a significant role in order to make cars more eco-friendly. They are as follows.

Improving Fuel Efficiency

Making cars more eco-friendly involves improving their fuel efficiency. Fuel efficiency is the measure of the amount of fuel consumed by a vehicle to travel a certain distance. The higher the fuel efficiency, the lower the carbon emissions. Here are some strategies to improve fuel efficiency:

  • Utilising lightweight materials: By using lightweight materials such as aluminium and carbon fibre. These make the cars lighter and result in better fuel efficiency.
  • Aerodynamic design: Reducing wind resistance makes the car move through more efficiently, which results in less fuel consumption.
  • Engine improvements: Improving variable valve timing, turbocharging and direct injection can significantly increase the output of the engine which in turn reduces fuel consumption.

Eco-friendly Manufacturing

The manufacturing process of cars can also be made more sustainable by adopting eco-friendly practices. One way is to power car manufacturing plants using renewable energy sources like wind and solar power to reduce carbon footprint.

  • Use of renewable energy: Car manufacturing plants can use renewable energy sources like wind and solar power to reduce their carbon footprint.
  • Waste reduction and recycling: Implementing recycling and waste reduction practices, can significantly reduce environmental impact. By recycling materials such as aluminium, for instance, car manufacturers can save energy and reduce waste.
  • Sustainable materials: Using sustainable materials such as bamboo, recycled plastic, and biodegradable materials can also help to make car manufacturing more eco-friendly. These do not have a significant impact on the environment.

Hybrid and Electric Vehicles

Hybrid and electric cars produce zero emissions and are fuel-efficient compared to conventional cars. Hybrid vehicles are equipped with both an electric motor and an internal combustion engine, whereas electric vehicles operate solely on electricity.

Some ways to make hybrid and electric more eco-friendly are given. 

  • Renewable energy: Electric vehicles can be charged with electricity from renewable sources like wind, solar, and hydroelectric power, which further lowers the carbon footprint of these vehicles.
  • Battery technology: Recent advancements in battery technology have resulted in batteries that are more efficient and long-lasting. But there is still a need to improve batteries further and increase their lifecycle. This will also reduce the landfills with used batteries.
  • Lightweight materials: Electric and hybrid vehicles, similar to traditional vehicles, can improve their fuel efficiency by using lightweight materials. Currently, batteries are also very heavy and require materials that are light in weight in order to improve fuel efficiency.

Alternative Fuels

These fuels are produced from renewable sources and produce less greenhouse gas emissions when compared to fossil fuels. A few examples are:

  • Hydrogen: It is a fuel that burns cleanly and only releases water vapour as a by-product. It can power fuel cell vehicles by generating electricity to operate the vehicle.
  • Biofuels: These are renewable fuels made from organic matter, like crops or agricultural waste, and have a lower emissions output compared to traditional fossil fuels.
  • Natural gas: It burns more cleanly than gasoline or diesel, resulting in fewer emissions. It is utilised in compressed natural gas (CNG) vehicles, which are gaining popularity.

What can we do on a personal level to make cars more eco-friendly?

We as individuals can play our role in order to make cars eco-friendly. Some of the ways we can achieve this are:

  • Choosing a fuel-efficient car

One of the simplest steps towards reducing your car’s carbon emissions is to opt for a fuel-efficient vehicle. You can consider buying a hybrid or electric car or choosing a conventional vehicle with good fuel efficiency. 

To make an informed decision, you can take the help of the U.S. Environmental Protection Agency’s (EPA) fuel economy website. This website allows you to compare various vehicles and make a well-informed purchase decision.

  • Driving smartly

Driving behaviours can have a significant impact on fuel consumption and emissions. To drive smarter, consider the following tips:

  1. Gradually accelerate and avoid rapid acceleration to save fuel and reduce emissions.
  2. Maintain a steady speed to reduce the need for sudden acceleration or braking.
  3. Avoid idling for extended periods to reduce unnecessary fuel consumption and emissions.
  4. Use cruise control, when possible, to maintain a consistent speed and reduce fuel usage.
  5. Remove unnecessary weight from the vehicle to improve fuel efficiency.
  • Minimising energy usage

Charging electric vehicles with renewable energy from sources like wind, solar, or hydroelectric power can further reduce the vehicle’s carbon footprint. If possible, consider generating clean energy through the installation of solar panels in your home or business to power your electric vehicle.

  • Car maintenance

Regularly maintaining your car can help keep it running efficiently, which can result in reduced emissions and fuel consumption. It is essential to follow the manufacturer’s recommended maintenance schedule and promptly address any issues that arise.

If the car is of an older model, getting emissions checked on a yearly basis will also let you know if your car is having any significant impact on the environment.

  • Alternative transportation and carpooling

Public transportation, biking, or walking are sustainable options that can be utilised when feasible. Carpooling or ridesharing with friends and colleagues can also reduce the number of cars on the road, leading to fewer emissions.

What role can the government play to make cars more eco-friendly?

The automotive industry can benefit from the government’s efforts to promote eco-friendly practices. Here are some ways in which the government can contribute to this effort:

  • Establishing fuel efficiency standards for new cars can incentivize automakers to produce more fuel-efficient vehicles, reducing emissions and saving drivers money on fuel costs.
  • Offering tax incentives for the purchase of electric or hybrid vehicles can encourage people to switch to more eco-friendly cars.
  • Investing in research and development of new technologies, such as battery technology, alternative fuels, and lightweight materials, can help make cars more eco-friendly.
  • Investing in infrastructure to support eco-friendly cars, such as electric vehicle charging stations and hydrogen fuelling stations, can facilitate their adoption.
  • Promoting the use of public transportation, such as buses and trains, can reduce the number of cars on the road and emissions.


To combat climate change, it is essential to reduce the carbon footprint of the transportation industry. Various approaches can be taken to make cars more eco-friendly, including improving fuel efficiency, using alternative fuels, introducing electric and hybrid vehicles, and making manufacturing processes sustainable. 

Individuals can also contribute by driving smarter, using alternative transportation, and choosing eco-friendly cars. Avoiding rapid acceleration and maintaining a consistent speed, can decrease fuel consumption and emissions. Minimising energy usage by charging electric vehicles with renewable energy, regularly maintaining the car, and performing yearly emissions checks can also help to reduce the vehicle’s carbon footprint.

Governments can play a crucial role in promoting and implementing eco-friendly practices, including providing infrastructure, funding research, offering tax incentives, and setting fuel efficiency standards. The collective efforts towards eco-friendly cars are an important step towards achieving a more sustainable future.
