Green cities are cities that are trying human actions that lead to climate change. These cities attempt to live in a sustainable way such that the needs of the present inhabitants are met without that of possible future inhabitants being placed in jeopardy. Green cities are also referred to as sustainable cities. This is because they adopt a sustainable way of doing things primarily across the following spheres; ecology, economics, politics and culture.
With the fact that it has become quite hard to deny the fact that human actions have an impact on the climate, it has become imperative that better and more sustainable alternatives to how we do things are adopted. These alternatives include green buildings, solar energy, recycling and so on. Green cities are a necessity today seeing as a very large percentage of the world’s population today live in cities and a lot of our aggregated actions wreak havoc on the environment. If the aforementioned alternatives are thus employed successfully, a lot will be accomplished towards reducing our negative impact on the environment, hence, green cities.
Green cities strive to reduce the negative impact of human actions by adopting alternatives that results in;
- a reduction in the quantity of waste materials being churned out,
- a reduction in the amount of gases being emitted into the atmosphere
- an expansion in the amount of materials being recycled
- an increment in housing density while making more open space available
- supporting and encouraging businesses that have a sustainable mode of operation
A green city can;
- Meet its food needs via a sustainable reliance on the encompassing countryside
- Should be able to cater for its energy and power demands through renewable and sustainable sources of energy
You are all familiar with Dubai which is not the only city benefiting from ours 28-year expertise in AI technology, IoT manufacturing, energy control and management. In 2016, Germany, aiming to run on renewable energy in a couple of decades, tasked Hitachi Chemical & Co. and Robotina, with making this a reality. Examples below are also examples of how the world is moving towards greener cities;
A high-technology bus system which facilitates easy movement within the city, thus greatly reducing the volume of vehicular traffic and in essence, energy usage and emission. The development of this system encouraged many people to move within close distance of transit hubs thus resulting in more spaces being opened up. The bus system (which was established in the late 1900’s) has about ¾ of the entire city population as users.
This city uses hydrogen as a fuel source for its buses and also employs renewable sources (such as geothermal and hydropower) for its energy production
Vancouver, British Columbia
This city derives 90% of its total energy from renewable sources of energy. It has about 200 parks and a waterfront that spans across 18 miles.
With people becoming increasingly aware of how our actions affect the environment, more and more actions are being taken to ensure that we leave as little impact on our environment as possible from here on out. Governments are taking more responsibility on these issues and introducing measures that are favorable, hence, green cities. Renewable energy is at an all-time high, reusing and recycling are gaining ground, stricter and harsher measures are being put in place to combat emission and so on. This is the future of the human race and it is here already.
