Sustainable Transport:benefical method for global environment

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 (roads, railways, airways, waterways, canals and terminals). 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 sustainable transport,it has methods that can release burden on environment and reduce air pollution from traditional transportation.Sustainable transport includes both public transport (electric buses, zero emissions buses, metro, electric train, trams, etc.) and private transport (pedestrians, bikes, electric vehicles, etc.).These transport may reducecarbon dioxide  emissions and atmospheric pollution and improved air quality in cities.

Cyclying system

Cycling may be the best and the most economical transportation in the world.By cycling,people can complete daily travelling like going to work,entertainment and exercises.Nowadays in many cities, the governments have constructed a lot of bikeways for people cycling.A bikeway is a lane, route, way or path which in some manner is specifically designed and /or designated for bicycle travel.Bike lanes demarcated by a painted marking are quite common in many cities. Cycle tracks demarcated by barriers, bollards or boulevards are quite common in some European countries such as the Netherlands, Denmark and Germany.In some terms, traffic jams have been released in these countries.

Electric public transport

Public transport (also known as public transportation, public transit, mass transit, or simply transit) 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 charge a posted fee for each trip.Public transport is always an important role and part in a city.In some terms public transports has the duty of helping city normally running for citizens like a structure.Examples of public transport include city buses, trolleybuses, trams (or light rail) and passenger trains, rapid transit (metro/subway/underground, etc.) 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.Unlike underground trains or tolleries,coaches and buses are traditional fuel vehicles.Fuel vehicles need great amounts gasoline or diesel oil which can generate lots of pollutants for air, water and other ecological environment.Fuel vehicles have a great influence on environment.Electric public transport only use electricity replaces fuel,which is called green energy.Buses are the busiest public transportation in the city.There is a great numbers of buses running in the city and they have to run everyday for ensuring citizens’ daily life.It’s no doubt that buses can generate lots of pollutants like carbon dioxide,methane and nitrous oxide during burning fuel.Electricity energy has advantages that release air pollution which generated by running fuel buses and less pollution for environment,not to mention underground trains or tolleries.

Electric vehicles:green cars

A green vehicle, clean vehicle, eco-friendly vehicle or environmentally friendly vehicle is a road motor vehicle that produces less harmful impacts to the environment than comparable conventional internal combustion engine vehicles running on gasoline or diesel, or one that uses certain alternative fuels.Green vehicles can be powered by alternative fuels and advanced vehicle technologies and include hybrid electric vehicles, plug-in hybrid electric vehicles, battery electric vehicles, compressed-air vehicles, hydrogen and fuel-cell vehicles, neat ethanol vehicles, flexible-fuel vehicles, natural gas vehicles, clean diesel vehicles, and some sources also include vehicles using blends of biodiesel and ethanol fuel or gasohol.As part of their contribution to sustainable transport, these vehicles reduce air pollution and greenhouse gas emissions.Green vehicles include vehicles types that function fully or partly on alternative energy sources other than fossil fuel or less carbon-intensive than gasoline or diesel especially electricity which is belongs to renewable energy sources.

Since 2016, a tendency swept the whole world is the development of electric transportation,especially developing renewable vehicles.These newly energy vehicles and low-carbon transportation are seen to be methods for “rescuring”world environment and these “methods” are all necessary.In the contiuning using these vehicles and cycling,great burden of pollution on envrionment will be effectively earsed in the future.
