Sustainable development is the kind of development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

The core concept behind sustainable development has been the limitations in the carrying capacity of spaceship earth.

“The nature and form of the urban environment is a critical determinant of the sustainability of our society as it is responsible directly for a large proportion of consumed energy, and influences indirectly the patterns and modes of energy consumed in everyday activities.”(Rickwood, 2008)

Energy Subsidies in Trinidad and Tobago
![Page 18: Concepts and Frameworks for approaching Urban Sustainability and Planning Module 1 Urban Sustainability and Smart Cities Dr. Asad Mohammed, Director of](https://reader035.vdocument.in/reader035/viewer/2022062409/5697bfbb1a28abf838ca10de/html5/thumbnails/18.jpg)

Over five per cent of total Government expenditure is the subsidy on fuel.
The fuel subsidy on gasoline for 2013 was over $4 billion.
The current price of gasoline at the pump in the United States is approximately TT$ 5.30 per litre compared to our current price of $2.70 per litre for super unleaded
Consequence is that there is little incentive to reduce care use, car pool and people are not sensitive to the real economic cost of gasoline.
Hence Trinidad has too many cars on the road

Transportation, land use and the environment
The spatial location of activities like residence, work, shopping, production and consumption give some indications on the required travel demand and average distances between activities
It is over the matter of density that the relationships between transportation, land use and the environment can be the most succinctly expressed.
The higher the level of density the lower the level of energy consumption per capita and the relative environmental impacts.

Transportation issues in developing CountriesIn developing cities where local technical capacity is weak, planning instruments are rudimentary and responsibilities, fragmented.
The development has been largely unplanned, and the provision of urban services has lagged due to limited budgets and inadequate technical capability
The location or direction of urban development influences transport investment, particularly in roads.
The poor, who tend to live on the fringes of cities, are usually burdened with the highest transport costs

Planning solutions in developing Countries
Substitutions of technology and alternate energy for sustainable consumption and rethinking the physical growth strategies .

Critical Issues in sustainable cities in the Caribbean
Brown vs the Green Agenda
Social and economic sustainability
Liveability more tangible than sustainability
Sustainable consumption important Mitigation important for economic sustainability
Realistic urban planning an management
Smart Growth vs Smart cities
