Cities use smart technology to accomplish sustainability goals. Examples include ensuring close proximity between citizens and landmarks to reduce transit times, and providing access to city bike rentals and electric vehicle charging stations.
1. Energy Efficiency

With the global population continuing to grow, cities need to be prepared for the challenge of becoming safe and sustainable places for their inhabitants. Whether it’s urban forests that absorb floodwaters or solar energy farms to power city buildings, creating green cities has become the focus of many innovators worldwide.

The first step in becoming a green city is reducing the amount of energy used in buildings and other municipal facilities. This can be done by using energy-efficient building materials, reducing the temperature of buildings with insulation or air conditioning and by making sure that lighting and appliances are turned off when they’re not being used. Additionally, all municipal buildings should be LEED (Leadership in Energy and Environmental Design) certified. LEED certification is a globally recognized standard that awards points for water efficiency, energy savings, CO2 emissions reduction and more.

Similarly, transportation is a big source of greenhouse gasses, so city leaders need to encourage their residents to ride bikes or take public transit instead of driving cars. They can do this by implementing bike paths, encouraging car-sharing programs and supporting eco-friendly transportation companies. They can also support the use of electric vehicles by providing refueling stations for them.

Finally, energy consumption can be cut by switching to renewable sources. Solar power is an excellent option for this because it provides clean, affordable electricity and creates jobs in the green economy. Cities should look into incorporating solar panels into their public buildings, schools and municipal structures, and they can even build wind turbines to harness the power of the wind.

In addition to improving energy efficiency, city leaders need to ensure that they are recycling 100% of their waste and utilizing recycled water. This can be achieved by implementing new recycling initiatives, encouraging citizens to reuse their food containers and requiring that all municipal facilities recycle at least 80% of their waste.

With the right policies in place, it is possible to turn a city into a green one. The best way to do this is by encouraging innovation in the private sector, as well as leveraging the resources of the public sector. Innovative 'eco-city districts' like the Western Harbor district in Malmo, Sweden are demonstrating the latest green technologies and how they can be applied in urban areas.
2. Water Conservation

Many of the most important eco-friendly urban living initiatives center around water conservation. The world’s cities consume an average of 49 gallons per person every day, so improving resource management is vital. Green infrastructure practices help reduce the amount of water that reaches sewers and waterways, reducing flood risks and climate change impacts. Additionally, harvested rainwater can be used for landscaping and toilet flushing, which can save a significant amount of money over the long term.

Planting trees and other vegetation helps to filter and clean stormwater runoff, lowering contaminant levels in local waterways. This is important because when water quality deteriorates, fish and shellfish populations decline and people become sick after eating contaminated seafood. Additionally, plants are great at reducing air temperatures and smog through their use of photosynthesis, cooling cities in hot weather.

Green roofs and other green infrastructure also improve water efficiency by reducing demand on municipal drinking-water systems. These practices are especially effective during droughts because they provide a source of low-cost water for non-potable uses, such as irrigation and gardening.

A growing number of cities are using green infrastructure practices in conjunction with rainwater harvesting to develop more sustainable water systems that are able to cope with drought conditions and climate change impacts. For example, green streets utilize pavements, bioswales and other techniques that allow stormwater to soak into the ground, reducing flooding and recharging aquifers. They also lower contaminant levels in waterways, preventing them from becoming too polluted to support healthy marine ecosystems and reducing public health costs associated with drinking contaminated ocean water.

The goal is to build green, livable cities that are both economically competitive and environmentally friendly. These urban areas must also be sustainable and equitable to ensure access for all to the natural resources they need. Fortunately, the resources and technology are available to make this a reality. Throughout the world, people are developing innovative solutions and partnerships to create green cities that are not only energy efficient but also socially connected and environmentally regenerative. As the world’s population continues to urbanize, these efforts will be critical for creating more environmentally friendly and resilient communities.
3. Indoor Gardens

Growing your own herbs, vegetables or fruits at home can be a fun and rewarding activity. But if you have limited outdoor space, or live somewhere with harsh winter temperatures that prevent growing your preferred vegetables and fruits, it can be difficult to get the fresh produce you desire. Fortunately, green innovations like indoor gardens allow you to enjoy your favorite foods all year round.

These easy-to-use indoor garden kits can be a great solution for urban dwellers with limited outdoor gardening space or those who simply want to be more eco-friendly. Many of these indoor gardening systems use hydroponics, which means the plants’ roots grow in a nutrient-rich water solution instead of soil. This allows you to grow double the amount of food in much less space than traditional soil-based gardening.

The best indoor gardens on the market include features that make it easy for anyone to create a successful vegetable or herb garden. Some even feature built-in LED lighting that can be customized to your specific plant’s needs. For example, the AeroGarden Bounty Basic has a simple setup process, an LCD screen that tells you when to water and feed your plants, and an app that gives you full control of your garden.

Urban green spaces are important to the health and wellbeing of city residents. Trees and green areas can help reduce air pollution, mitigate rising local temperatures, and promote healthy diets and physical activity. They can also provide a habitat for insects and wildlife.

Increasing the number of green spaces in cities is a key strategy to improve environmental and social sustainability. This can be done by building urban farms and community gardens, incorporating edible landscaping, and supporting recycling and composting programs. Moreover, preserving agricultural land within cities can shorten food supply chains and reduce the CO2 emitted when transporting food from rural to urban areas.

Green initiatives in urban settings can also focus on reducing energy consumption, using renewable sources of power, and improving waste management. For instance, converting paved surfaces to greenery and implementing rainwater harvesting strategies can help reduce greenhouse gas emissions from buildings. Other ways to promote green living in cities include promoting cycling and walking to reduce vehicle traffic, encouraging the use of solar panels and wind turbines, and implementing sustainable stormwater management.
4. Sustainable Transportation

While sustainability initiatives may be able to reduce the environmental footprint of a city, it’s important to remember that the built environment and transport infrastructure are long-term investments. For example, a city’s fleet of automobiles are likely to remain in service for ten or more years, and replacing them with newer vehicles that consume less fuel can make only a small difference.

Fortunately, urban transportation can be improved in several ways that help achieve sustainable living goals. A few of the most effective measures are to encourage walking and cycling, promote public transportation use, restrict vehicle traffic in congested areas, and encourage ride-sharing. In addition, a number of companies are developing greener vehicles and technologies that are more efficient, such as electric cars and hyperloops.

A sustainable transportation system is one that allows people to get to and from work or school, shop for food, visit friends and family, and access services and recreational activities without causing harm to the environment. It includes the planning and operation of transport modes and facilities, as well as the provision of adequate infrastructure for walking and cycling. It also limits emissions and waste within the Earth’s ability to absorb them, and ensures a reasonable level of social equity.

In general, green cities rely on low carbon technologies, energy efficiency, water conservation and preservation and transportation alternatives to reduce greenhouse gas emissions. Increasingly, these are being combined to create a city that is both environmentally friendly and economically competitive.

Many cities are taking action to become greener, and some have reached the next stage—making their buildings eco-friendly by using more renewables such as solar power. In addition, some cities are converting their streets to pedestrian pathways, creating public bike shares, and implementing parking rules that discourage automobile travel.

Other green cities are going further and are requiring that all residential and commercial buildings adhere to strict sustainable design standards. These standards include reducing water consumption, building energy-efficient homes, and using non-toxic materials. Some are even encouraging residents to plant gardens, which can further reduce the city’s dependence on fossil fuels for energy. And some cities are even transforming into “forest cities,” such as the stunning Forest City in China, which is covered in trees and other vegetation!
