Electric vehicles aren’t a fix for carbon emissions. These 3 things ne

Transportation is Responsible for 24% Of energy-related carbon emissions around the world. Half of these emissions come from carrying goods and services, and the other half is from transporting people from A to B – also known as “Passenger transport. “

Passenger transportation has a huge impact on our environment, and is one of the biggest factors in determining where we live and work. It could be bumper-to-bumper traffic in Los Angeles, Danish cities full of bikes, Japanese ball trains, sizzling Vietnamese mopeds, taxi ranks with India’s famous tricycles, or bustling London Underground trains.

Familiarity Electric vehicles (EVs) on a huge scale has often been defined as a solution to reduce passenger emissions – witnesses to Britain’s plans All new homes and upgraded buildings will have 2022 car charging points.

However, Recent research The US has proven that electrifying cars alone will not be enough for the transportation sector to reach an ambitious world Climatic action targets In order to prevent more than 2 degrees Celsius from global warming.

In addition, a population that continues to depend on cars poses significant problems for emerging cities. With increasing urbanization and space at a high price, we need to reduce vehicle ownership in cities if we want to keep them as reasonable and accessible as possible. Huge quantities Land that could otherwise be used for people’s residence or be dedicated to nature is still reserved for roads and parking lots.

While electric cars certainly help cope with increasing transportation emissions, simply focusing on replacing conventional cars with electric vehicles is Missing an opportunity For countries to develop an alternative Means of transport Beyond hanging in the car.

Funds for climate action – incl Adaptation beam, An international fund supported by the United Nations that helps developing countries adapt to climate change –Are expected to Reach funding of £ 74 billion by 2023. Much of this money is channeled to sustainable infrastructure projects, which can help developing countries build efficient and sustainable mass transport systems.

Of the UN Intergovernmental Panel On climate change Advocates b Access to passenger transportation planning called “Avoid, set, improve, “Which is adapted from a framework first developed in Germany in the early 1990s:

avoid

“Avoid” refers to reducing the need for transportation in the first place. It involves planning new urban areas and redeveloping old areas so that they are as organized as possible so that people do not have to travel far for their work, shopping, education and leisure needs. While years of investing in roads have made it very difficult for some cities to stay away from car use, the future is not yet written for many of our growing cities.

This access also includes connecting homes and rural towns to the Internet so that people can work easily and cheaply from home, leaving free road space for people – like doctors or teachers – who cannot.

shift

“Shift” means the transition from necessary travel to sustainable, active means of transportation and higher occupancy. Instead of single cars, for example, we could use buses, trains, bicycles, scooters, skateboards or walking trails. Around the world, we can see exciting examples of how countries have managed to keep this change away from dependence on high-carbon cars.

God TransMilenio The bus system, which operates in the cities of Bogota and Socha in Colombia, is one of the largest of its kind in the world. Transportation between one million and two million people daily, a wide range of stations, dedicated bus routes and cheap ticketing stations create an easily accessible service.

Increasing the absorption of active cycling is another way to encourage this change. Electric bikes are among Grows fastest Types of transportation in China. Motor-driven travel encourages cycling on longer journeys in mountainous areas, warmer areas and among less fit people. Studies from Sweden and Norway Show that cyclists who switch from regular bikes to electric bikes increase their number of trips and the distances they travel on average for each ride.

Recently, Berliners voted to expand the car limits in the German city to cover the city’s 88 square kilometers – a proposal that would create the The largest in the world An urban area without cars. Such actions can address the safety concerns of pedestrians and cyclists, who fear navigation alongside heavy vehicles moving at high speed, by providing separate active driving lanes. It is important, Researchers noted That without means of restricting the use of the vehicle, other means of encouraging the absorption of public transport, walking and cycling have little effect.

Once unnecessary travel has been interrupted by things like poor urban planning and an employer policy that requires the presence of office workers, and once safe public transportation systems or active travel options have been provided, we can focus on making our vehicles today more sustainable.

to improve

Although fuel efficiency has slightly reduced fuel consumption per km of car transport, the demand for passenger transport continues to grow – that is, overall, increasing emissions from passenger transport outweighs the reduction in efficiency. , Trains and vehicles from fossil fuels to electric.

The key to reducing passenger emissions is to provide access and use of electric cars only when there are no other reasonable travel options. If we do, we have an opportunity to end our dependence on cars while helping as many people as possible to travel.
