-->Social equity: Relates to conditions favoring a distribution of resources among the current generation based upon comparative levels of productivity. 
Economic efficiency: Concerns conditions permitting higher levels of economic efficiency in terms of resource and labor usage. It focuses on capabilities, competitiveness, flexibility in production and providing goods and services that supply a market demand. 
Environmental responsibility: Involves a "footprint" which is lesser than the capacity of the environment to accommodate. 

 

Transport that minimizes harmful effects on the environment and the depletion of natural resources, such as walking, cycling, and fuel-efficient public transport, and hence can be sustained in the long term. 

1)       Sustainable transport refers to the broad subject of transport that is sustainable in the senses of social, environmental and climate impacts and the ability to, in the global scope, supply the source energy indefinitely. 

Sustainable Transport is sometimes known as Green Transport and it is any form of transport that does not use or rely on dwindling natural resources. Instead it relies on renewable or regenerated energy rather than fossil fuels that have a finite life expectancy. For this reason it is said to have a low or a negative effect on the environment since it makes use of energy sources that are sustainable. 

- water or air transport

- the source of energy

- the infrastructure used to accommodate the transport (roads, railways, airways, waterways, canals and terminals)

- pipelines for transporting liquid or gas materials

- transport operations and logistics as well as transit-oriented development

The World Health Organisation has estimated that a city needs to allocate at least nine square metres of green space for each resident. Yet many fast-growing cities around the world are making do with less than two square metres after allocation of ever more precious land to feed the insatiable appetite for roads and parking. 

Adding roads and highways merely encourages more people to use private transport modes.

The greatest impact individuals can have in fighting climate change is to have one fewer child, according to a new study that identifies the most effective ways people can cut their carbon emissions.

The next best actions are selling your car, avoiding long flights, and eating a vegetarian diet. These reduce emissions many times more than common green activities, such as recycling, using low energy light bulbs or drying washing on a line. However, the high impact actions are rarely mentioned in government advice and school textbooks, researchers found.

Carbon emissions must fall to two tonnes of CO2 per person by 2050 to avoid severe global warming, but in the US and Australia emissions are currently 16 tonnes per person and in the UK seven tonnes. “That’s obviously a really big change and we wanted to show that individuals have an opportunity to be a part of that,” said Kimberly Nicholas, at Lund University in Sweden and one of the research team.

The new study, published in Environmental Research Letters, sets out the impact of different actions on a comparable basis. By far the biggest ultimate impact is having one fewer child, which the researchers calculated equated to a reduction of 58 tonnes of CO2 for each year of a parent’s life.

The figure was calculated by totting up the emissions of the child and all their descendants, then dividing this total by the parent’s lifespan. Each parent was ascribed 50% of the child’s emissions, 25% of their grandchildren’s emissions and so on.

Transportation typifies the FutureStructure framework. (FutureStructure is a sister publication of Governmet Technology.) Soft infrastructure — the realm of concepts, policies and legislation — is rapidly evolving to accommodate the demand for global investment in hard transportation infrastructure. Technology is bridging the two as vehicles and the infrastructure on which they operate become increasingly connected.

Traffic and population growth create demand for more transportation infrastructure, but many jurisdictions don’t have sufficient money or space to build more roads and rail.

Despite cities lacking funds population growth will continue — the World Health Organization expects 7 out of 10 people on the planet will live in cities by mid-century. Coupled with climate change concerns, cities leaders must start rethinking the very nature of existing transportation systems.

The new technology can help to the development for example with the creation of electronic cars, this cause the reduction of the green gas in the atmosfere so reduce the pollution.  

- The Sustainable transport means a transport without pollution. It use a renewable or regenerated energy like fossil fuels that have a finite life expectancy. 

- The New Technology could help the development of Sustainable Transport with the creation of new machines,  which use green energy. 

-  Replacing old cars with gasoline or another bad fuel by other with electric engine. 

- We can reduce the emission of pollutants buying electric cars, using bicycle or public transport. 

- Using public transport instead of your car.
