Smart growth is an urban planning and transportation theory that concentrates growth in compact walkable urban centers to avoid sprawl. It also advocates compact, transit-oriented, walkable, bicycle-friendly land use, including neighborhood schools, complete streets, and mixed-use development with a range of housing choices. The term "smart growth" is particularly used in North America. In Europe and particularly the UK, the terms "compact city", "urban densification" or "urban intensification" have often been used to describe similar concepts, which have influenced government planning policies in the UK, the Netherlands and several other European countries.
The California Air Resources Board is an agency of the government of California that aims to reduce air pollution.

Sustainable transport refers to ways of transportation that are sustainable in terms of their social and environmental impacts. Components for evaluating sustainability include the particular vehicles used for road, water or air transport; the source of energy; and the infrastructure used to accommodate the transport. Transport operations and logistics as well as transit-oriented development are also involved in evaluation. Transportation sustainability is largely being measured by transportation system effectiveness and efficiency as well as the environmental and climate impacts of the system. Transport systems have significant impacts on the environment, accounting for between 20% and 25% of world energy consumption and carbon dioxide emissions. The majority of the emissions, almost 97%, came from direct burning of fossil fuels. In 2019, about 95% of the fuel came from fossil sources. The main source of greenhouse gas emissions in the European Union is transportation. In 2019 it contributes to about 31% of global emissions and 24% of emissions in the EU. In addition, up to the COVID-19 pandemic, emissions have only increased in this one sector. Greenhouse gas emissions from transport are increasing at a faster rate than any other energy using sector. Road transport is also a major contributor to local air pollution and smog.

Washington, D.C. has a number of different modes of transportation available for use. Commuters have a major influence on travel patterns, with only 28% of people employed in Washington, D.C. commuting from within the city, whereas 33.5% commute from the nearby Maryland suburbs, 22.7% from Northern Virginia, and the rest from Washington, D.C.'s outlying suburbs.
California's transportation system is complex and dynamic. Although known for its car culture and extensive network of freeways and roads, the state also has a vast array of rail, sea, and air transport. Several subway, light rail, and commuter rail networks are found in many of the state's largest population centers. In addition, with the state's location on the West Coast of the United States, several important ports in California handle freight shipments from the Pacific Rim and beyond. A number of airports are also spread out across the state, ranging from small general aviation airports to large international hubs like Los Angeles International Airport and San Francisco International Airport.
The United States produced 5.2 billion metric tons of carbon dioxide equivalent greenhouse gas (GHG) emissions in 2020, the second largest in the world after greenhouse gas emissions by China and among the countries with the highest greenhouse gas emissions per person. In 2019 China is estimated to have emitted 27% of world GHG, followed by the United States with 11%, then India with 6.6%. In total the United States has emitted a quarter of world GHG, more than any other country. Annual emissions are over 15 tons per person and, amongst the top eight emitters, is the highest country by greenhouse gas emissions per person.
The Clean Cities Coalition Network is a coordinated group of nearly 100 coalitions in the United States working in communities across the country to advance affordable, domestic transportation fuels, energy-efficient mobility systems, and other fuel-saving technologies and practices.
The DC Streetcar is a surface streetcar network in Washington, D.C. that consists of a single line running 2.2 miles (3.5 km) in mixed traffic along H Street and Benning Road in the city's Northeast quadrant.
Active mobility, soft mobility, active travel, active transport or active transportation is the transport of people or goods, through non-motorized means, based around human physical activity. The best-known forms of active mobility are walking and cycling, though other modes include running, rowing, skateboarding, kick scooters and roller skates. Due to its prevalence, cycling is sometimes considered separately from the other forms of active mobility.
Shared transport or shared mobility is a transportation system where travelers share a vehicle either simultaneously as a group or over time as personal rental, and in the process share the cost of the journey. It is a transportation strategy that allows users to access transportation services on an as-needed basis, and can be regarded as a hybrid between private vehicle use and mass or public transport. Shared mobility is an umbrella term that encompasses a variety of transportation modes including carsharing, Bicycle-sharing systems, ridesharing companies, carpools, and microtransit.

Public transport is a system of transport for passengers by group travel systems available for use by the general public unlike private transport, typically managed on a schedule, operated on established routes, and that may charge a posted fee for each trip. There is no rigid definition of which kinds of transport are included, and air travel is often not thought of when discussing public transport—dictionaries use wording like "buses, trains, etc." Examples of public transport include city buses, trolleybuses, trams and passenger trains, rapid transit and ferries. Public transport between cities is dominated by airlines, coaches, and intercity rail. High-speed rail networks are being developed in many parts of the world.

Michael Replogle is an internationally recognized expert and advisor in the field of sustainable transport. He co-founded the Institute for Transportation and Development Policy (ITDP) in 1985, a nonprofit organization that promotes environmentally sustainable and equitable transportation projects and policies worldwide, as well as Bikes Not Bombs in 1984. He was the president of ITDP from 1985–1992 and 1998-2009, and managing director of ITDP from 2009-2015. His seminal 1987 paper on sustainable transport was the first to define the term. In 2024, his expert testimony led to a pathbreaking settlement of a lawsuit between Hawai'i Department of Transportation and 13 youth plaintiffs, represented by Our Children's Trust and Earthjustice, for a statewide plan to decarbonize transportation by 2045, achieving a 50% reduction by 2030, with 5-year targets and annual reporting.
