The Environmental Impact of Transportation
Human activities such as burning fossil fuels, deforestation and industrial production release greenhouse gases (GHGs) like carbon dioxide and methane. These gases trap heat in the atmosphere, causing global temperatures to rise and intensifying climate change. A major share of emissions comes from energy use in industry, buildings and agriculture. However, transportation alone contributes more than 16% of global emissions, with road vehicles being the largest source. Addressing transport-related emissions is therefore crucial for building a sustainable future.
Electric & Hybrid Vehicles
Electric vehicles (EVs) are cars that run solely on electricity through their batteries, without the need for a gasoline engine. These cars are environmentally friendly because they produce no exhaust fumes, are less expensive to operate than conventional cars, and are simple to maintain because they do not contain a complex combustion engine. Hybrid cars, on the other hand, use a combination of gasoline and electricity to provide power, making them more fuel-efficient and producing fewer harmful emissions than conventional cars. They are also suitable for long journeys thanks to their ability to combine electric power with gasoline. Both types represent an important step toward more efficient and environmentally friendly vehicles.
How Individuals Can Make a Difference
Walking, biking, using public transportation, and driving electric vehicles help reduce greenhouse gas emissions and air pollution. These alternatives to traditional gas-powered cars consume less or no fossil fuels, preserving natural resources. Public transport and active travel like walking or biking also reduce traffic congestion and urban noise. Overall, they contribute to cleaner air, lower carbon footprints, and a healthier planet.
