The Big Impact of Bigger Cars
The rise of SUVs (Sport Utility Vehicles) is more than just a trend, it’s a significant issue that affects our planet and our daily lives. With nearly half of all new cars sold in 2023 being SUVs, we’re seeing a dramatic shift in vehicle size preferences. This shift poses challenges, such as increased greenhouse gas emissions and pedestrian safety concerns, but it also opens doors for climate action. By transitioning from gas-guzzling SUVs to electric vehicles (EVs), we could cut down on pollution significantly. Imagine if all gas-powered SUVs were replaced with electric ones—this could prevent around 770 million metric tons of carbon dioxide from entering the atmosphere! This topic connects directly to your future as you think about the impact of your choices on the environment and the community around you. Understanding the implications of vehicle sizes is crucial as we consider sustainable living and our role in combating climate change.

Greenhouse Gas Emissions
Gases released into the atmosphere that trap heat, contributing to climate change (e.g., carbon dioxide from cars).

Carbon Footprint
The total amount of greenhouse gases produced directly and indirectly by an individual, organization, or product, often measured in carbon dioxide equivalents.

Electric Vehicles (EVs)
Cars that run on electricity instead of gasoline or diesel, producing no tailpipe emissions.

Sustainability
Practices that meet the needs of the present without compromising the ability of future generations to meet their own needs, especially regarding environmental health.

Lithium-Ion Batteries
Rechargeable batteries commonly used in electric vehicles that store energy for powering the car.

Pedestrian Safety
The measures and considerations taken to protect people walking in areas shared with vehicles, especially regarding the risks posed by larger vehicles.
