What makes a city sustainable?


Several factors contribute to making a city sustainable.

Energy

Large and populated cities are huge contributors to pollution and climate change due to the overuse of fossil fuels for energy. Recently there has been a push in the use of more sustainable forms of energy or ‘green energy,’ such as solar energy, geothermal energy, and the likes to reduce carbon footprint.

Transportation infrastructure

Good public transport is the need of the hour. Cities that have the kind of infrastructure with easy access to public transport will automatically reduce their carbon footprint. When a city has good and affordable public transport, its citizens are more likely to rely on public transport for everyday travel.

Affordability

Being a sustainable city also means that the means to achieve sustainability should be affordable to all. The use of green energy for houses should be affordable and easily accessible to the citizens of a city to ensure that sustainability becomes a natural part of their lifestyle.

Pollution

Although no level of pollution is safe, efforts to reduce the level of pollution can improve the level of life expectancy and pave the way for a healthy future. Having good air quality is crucial especially for large cities and contributes to a sustainable lifestyle.

Air quality

The quality of air is an important aspect of what makes a city liveable and sustainable. Curbing pollution, increasing the number of green spaces, encouraging the use of public transport, and the use of green energy can help improve the air quality in cities, making the air healthy and breathable.

CO2 emissions

Consumption of fossil fuels like coal, oil, and natural gas for energy and electricity increases the amount of CO2 emissions in the air. CO2 makes up the majority of greenhouse gases in the atmosphere and is greatly contributing to climate change. Many cities are working towards reducing their carbon footprints and reduce the use of fossil fuels.

Percentage of green space available

As urbanization continues to grow, the level of pollution in cities has and will reach dangerous levels. Having large green spaces like parks and other such areas can help reduce the effects of pollution and the urban heat effect.
