Climate Change: Less Cars, More Public Transport

Climate change is one of the most pressing issues of our time, and it's something that we all need to take seriously. The scientific consensus is clear: the Earth is warming, and human activity is the primary cause. The consequences of climate change are severe, and they're already being felt around the world. From more frequent and severe weather events to rising sea levels, climate change is affecting every aspect of our lives.


In this article, we'll explore why we need fewer cars and more investment in public transport. Transportation is a major contributor to greenhouse gas emissions and reducing our reliance on cars is an important step in the fight against climate change. But it's not just about reducing emissions - investing in public transport has a wide range of benefits for both individuals and society. First and foremost, reducing the number of cars on the road is crucial for reducing greenhouse gas emissions. Transportation accounts for around a third of global greenhouse gas emissions, and cars are a major contributor to this. In fact, the transportation sector is the second-largest contributor to greenhouse gas emissions in the US, after electricity generation. By reducing the number of cars on the road, we can make a significant dent in our overall emissions.

But it's not just about emissions. Investing in public transport can have a range of other benefits as well. For one, it can help reduce congestion on the roads. As anyone who's ever been stuck in traffic knows, congestion is a major problem in many cities. It's not just frustrating - it's also bad for the environment, as cars idling in traffic emit more pollutants than cars that are moving. By investing in public transport, we can help reduce congestion and make our cities more liveable.

Public transport can also be more affordable than owning a car. Cars are expensive to buy and maintain, and the cost of fuel and insurance can add up quickly. Public transport, on the other hand, is often more affordable and can save individuals and families money in the long run. This is especially true in cities, where parking can be expensive and public transport is often readily available. Investing in public transport can also help create jobs and stimulate economic growth. Building and maintaining public transport infrastructure requires a lot of labour, and this can help create jobs in communities that need them. Additionally, public transport can make it easier for people to get to work, which can help stimulate economic growth by increasing productivity and reducing absenteeism.


There are many examples of cities around the world that have successfully invested in public transport and seen positive results. In Oslo, for example, the city has implemented a range of policies designed to reduce car usage and increase public transport usage. This includes making public transport more affordable, increasing the number of bus and tram lines, and investing in bike infrastructure. The results have been impressive - the percentage of trips taken by car in Oslo has fallen from 43% in 2015 to 32% in 2019.

Another example is Curitiba, Brazil. In the 1970s, the city began investing in a bus rapid transit (BRT) system, which has since become one of the most successful and well-known public transport systems in the world. The BRT system has helped reduce congestion and emissions and has also spurred economic growth and development in the city.

These examples do show that if investment and effort is used to improve a city or even a countries Carbon emission, it is possible to do so. If planned effectively whereby it clearly has been in the projects I have named. Furthermore, these projects have also shown that even when reducing carbon emissions economic growth still can occur and even improve if done efficiently.

Overall thoughts:

In conclusion, reducing our reliance on cars and investing in public transport is crucial for addressing climate change and creating more liveable, sustainable cities. It's not just about reducing emissions - investing in public transport can also help reduce congestion, save individuals and families money, create jobs, and stimulate economic growth. There are many successful examples of cities around the world that have implemented policies and infrastructure to promote public transport, and there's no reason why other cities can't follow their lead. By working together and taking bold action.
