Sustainable transportation practices aim to reduce traffic congestion by promoting alternative modes of transportation, such as public transit, walking, and cycling.

Sustainable transportation policies aim to reduce the environmental impact of transportation by promoting alternative fuels, energy-efficient vehicles, and transportation systems that minimize greenhouse gas emissions and air pollution.

Gasoline-powered vehicles emit greenhouse gases and air pollutants, contributing to climate change and poor air quality. Electric vehicles, public transit, and bicycles are all considered sustainable modes of transportation.

Multimodal transportation refers to a transportation system that allows users to seamlessly switch between different modes of transportation, such as public transit, walking, cycling, and personal vehicles.

Building more roads and highways can lead to increased traffic congestion and vehicle emissions, which are counterproductive to sustainable transportation goals.

A car-free city is a transportation system that prioritizes walking, cycling, and public transit over private vehicles. This can be achieved through measures such as pedestrian-friendly infrastructure, dedicated bike lanes, and restrictions on car usage.

Public transportation typically results in lower greenhouse gas emissions compared to private vehicles, as it allows for more efficient use of energy and resources.

An electric vehicle is a vehicle that runs on electricity stored in batteries, rather than relying on fossil fuels.

Gasoline is a fossil fuel, while biodiesel, ethanol, and natural gas are all alternative fuels that can be used to power vehicles.

Sustainable transportation refers to a transportation system that aims to minimize environmental impact, promote social equity, and ensure accessibility for all.

Building more roads and highways can lead to induced demand, where the increased road capacity attracts more vehicles, resulting in no net reduction in traffic congestion.

Zero-emission transportation refers to a transportation system that relies solely on renewable energy sources, such as electricity, hydrogen, or biofuels, to power vehicles.

Walking and cycling do not produce greenhouse gas emissions, unlike motorized vehicles.

Multimodal transportation refers to a transportation system that allows users to seamlessly switch between different modes of transportation, such as public transit, walking, cycling, and personal vehicles.
