Flashcards
0/20
Noise Pollution
Unwanted or harmful outdoor sound created by transportation vehicles. Can lead to health issues such as stress, hearing loss, and sleep disturbances.
Lifecycle Emissions
Includes all emissions from the production, operation, and disposal of a transportation vehicle, highlighting the importance of looking at the total environmental impact.
Soil Contamination
Accidental spills and runoff from roads can contaminate soil with hazardous substances, impacting plant life and water quality through infiltration.
Habitat Disruption
Construction of transportation infrastructure can lead to habitat destruction, fragmentation, and barrier effects, threatening wildlife populations.
Climate Resilience
The ability of transportation infrastructure to withstand and adapt to climate change impacts such as sea-level rise, extreme weather events, and higher temperatures.
Modal Shift
Encouraging the use of more environmentally friendly modes of transportation, like cycling, walking, or public transit, over less sustainable options like personal automobiles.
Water Pollution
Transportation can lead to water pollution through runoff of oil, fuel, and chemicals, affecting aquatic ecosystems and potentially contaminating drinking water supplies.
Lifecycle Analysis
A method to assess the environmental aspects and potential impacts throughout a product's life cycle, from raw material acquisition through production, use, and disposal.
Light Pollution
Excessive, misdirected, or intrusive artificial light from transportation sources that can disrupt ecosystems and human health.
Fuel Efficiency Standards
Regulations that set specific performance requirements for the fuel economy of vehicles, reducing overall emissions from the transportation sector.
Greenhouse Gas Emissions
Carbon dioxide (CO2) and other greenhouse gases released from vehicles, contributing to global warming. In transportation, this is primarily due to combustion of fossil fuels in cars, trucks, and airplanes.
Air Quality
Refers to the presence of pollutants in the air. Transportation sources emit nitrogen oxides, sulfur dioxide, particulate matter, and volatile organic compounds, which can affect human health and the environment.
Thermal Pollution
Increase in temperature caused by transportation infrastructure, such as dark pavements absorbing heat, impacting local climates and urban heat islands.
Resource Consumption
Transportation requires materials (like steel and concrete) and energy resources, which can lead to resource depletion and ecological footprint.
Sustainable Urban Planning
Incorporating green spaces, public transit, and walkable areas to reduce reliance on personal cars and mitigate transportation-related environmental impacts.
Carbon Footprint
The total amount of greenhouse gases produced to directly and indirectly support human activities, commonly expressed in equivalent tons of carbon dioxide (CO2).
Alternative Fuels Impact
The use of fuels like electricity, hydrogen, and biofuels to reduce the environmental footprint of transportation, compared to traditional fossil fuels.
Ecosystem Services Disruption
Transportation infrastructure can alter ecosystems and the services they provide, like water purification, flood regulation, and carbon sequestration.
Electric Vehicle Adoption
Switching to electric vehicles reduces tailpipe emissions, but also shifts the environmental impact to electricity generation and battery production processes.
Biodiversity Loss
Transportation can cause loss of biodiversity due to habitat destruction and pollution, affecting ecosystem health and resilience.
