The automotive industry plays a significant role in global warming and climate change. The primary influence comes from the emissions of greenhouse gases, particularly carbon dioxide (CO2), produced by car engines. Carbon dioxide is the main anthropogenic greenhouse gas that enhances the greenhouse effect and leads to global warming. These emissions create a dense layer in the atmosphere that traps heat and results in an increase in the Earth's surface temperature.
In addition to carbon dioxide, cars also emit other harmful substances such as nitrogen oxides (NOx) and heavy metals, which pollute the air and cause harm to human health and ecosystems. High concentrations of nitrogen oxides contribute to smog and acid rain, which have negative consequences for plants, animals, and water resources.
Apart from direct emissions, automobile infrastructure and traffic congestion also have an impact on the climate. The construction and maintenance of roads, parking lots, and fuel stations require significant energy and resources, leading to additional greenhouse gas emissions. Traffic congestion increases travel time and leads to increased fuel consumption and emissions.
However, there are positive changes happening in the automotive industry. The adoption of environmentally friendly technologies, such as electric and hybrid vehicles, helps reduce greenhouse gas emissions and mitigate the negative impact on the climate. Support for public transportation, the development of cycling and pedestrian zones, and car-sharing principles contribute to reducing car traffic and emissions.
