- "The environmental effects of transport are significant because transport is a major user of energy, and burns most of the world's petroleum." - "This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through emission of carbon dioxide."
The study of the impact of transportation on the environment, including air pollution, noise pollution, and greenhouse gas emissions.
Transportation modes (air, road, rail, water): Understanding the strengths and weaknesses of different transportation modes and their impact on the environment.
Transportation infrastructure: The planning and design of transportation infrastructure and its impact on the environment.
Traffic flow and congestion: Traffic flow analysis and management to optimize transportation systems for efficiency and environmental sustainability.
Urban planning and transportation: Land use planning and transportation integration for sustainability and livability in urban areas.
Alternative fuel vehicles: The development, deployment, and impact of vehicles using alternative fuels (electric, hydrogen, biofuels) on the environment.
Sustainable transportation policies: Government policies, regulations, and incentives that promote sustainable transportation practices and reduce negative environmental impacts.
Green logistics and supply chain management: The role of logistics and supply chain management in reducing the environmental impact of transportation and moving towards a more sustainable future.
Carbon footprint and emissions trading: Tools and techniques for measuring and reducing carbon emissions in the transportation sector, including the use of emissions trading schemes.
Environmental impact assessment: The assessment of transportation projects' environmental impacts and their mitigation strategies.
Sustainable transportation technology and innovation: Research and development of new technologies and innovations that can promote sustainable transportation practices and reduce negative environmental impacts.
Active transportation: The promotion of walking, cycling, and other non-motorized modes of transportation for sustainable and healthy urban living.
Public transportation and transit-oriented development: The role of public transportation and transit-oriented development in promoting sustainable transportation and urban living.
Environmental justice and equity: The impacts of transportation on marginalized communities and the role of transportation policies in addressing equity concerns.
Environmental impact of global trade: The environmental impacts of global trade and the role of transportation in facilitating it.
Sustainable tourism and transportation: The relationship between tourism and transportation and the potential for sustainable tourism practices to reduce negative environmental impacts.
Automobiles: Cars and trucks are one of the primary sources of air pollution, greenhouse gas emissions, and noise pollution.
Public Transit: Public transportation, such as buses and subways, can reduce traffic congestion and provide an eco-friendlier mode of travel. However, these vehicles still contribute to air pollution and carbon emissions.
Trains: Trains generally emit less greenhouse gases than air or car transport. However, their use of fuel and the construction and maintenance of rail infrastructure can have its own environmental impact.
Airplanes: Airplanes are significant emitters of greenhouse gases and contribute to climate change. They also generate significant noise pollution and damage local ecosystems with airport construction and expansions.
Bicycles: One of the most sustainable and eco-friendly transportation modes available. Bikes don't emit greenhouse gases, require little to no fuel, and provide a healthy mode of exercise.
Watercraft: Shipping and boating account for a small proportion of global carbon emissions, as newer ships and boats tend to use cleaner fuels. However, the waste of cruise ships and the impact of major shipping routes on marine ecosystems can be significant.
Walking: Walking is, of course, the most sustainable and eco-friendly mode of transportation, requiring no fuel or emissions.
- "Within the transport sector, road transport is the largest contributor to global warming."
- "Environmental regulations in developed countries have reduced the individual vehicle's emission."
- "However, this has been offset by an increase in the number of vehicles, and increased use of each vehicle (an effect known as the Jevons paradox)."
- "Some pathways to reduce the carbon emissions of road vehicles have been considerably studied."
- "Energy use and emissions vary largely between modes."
- "Environmentalists call for a transition from air and road to rail and human-powered transport."
- "Increase transport electrification and energy efficiency."
- "Other environmental impacts of transport systems include traffic congestion and automobile-oriented urban sprawl, which can consume natural habitat and agricultural lands."
- "By reducing transport emissions globally, it is predicted that there will be significant positive effects on Earth's air quality, acid rain, smog, and climate change."
- "Health effects of transport include noise pollution and carbon monoxide emissions."
- "While electric cars are being built to cut down CO2 emission at the point of use, an approach that is becoming popular among cities worldwide is to prioritize public transport, bicycles, and pedestrian movement."
- "Redirecting vehicle movement to create 20-minute neighbourhoods that promotes exercise while greatly reducing vehicle dependency and pollution."
- "Some policies are levying a congestion charge to cars for travelling within congested areas during peak time."
- "This creates air pollution, including nitrous oxides and particulates."
- "Transport is a significant contributor to global warming through emission of carbon dioxide."
- "Energy use and emissions vary largely between modes."
- "Automobile-oriented urban sprawl... can consume natural habitat and agricultural lands."
- "Increase transport electrification and energy efficiency."
- "Health effects of transport include noise pollution and carbon monoxide emissions."
