Cities and their inhabitants produce huge amounts of green house gases, contributing to global warming and environmental damage. In response, a number of communities are focused on reducing their carbon-emissions, with some attempting to go entirely carbon-free.

The Sustainable City in Dubai, a 500-home complex outside Dubai City, proposes one solution. Scroll through the gallery to discover how other communities are living sustainably.

Fujisawa in Japan is a "sustainable smart town" built by Panasonic in collaboration with 17 other companies. Located 50km west of Tokyo and receiving its first batch of residents in November 2014, the town's infrastructure is based on a smart grid which connects every building to a central real-time energy network. This means the energy demands of the inhabitants are connected to the variables of renewable energy.

The 600 houses and 400 apartments, which can accommodate 3,000 people, are equipped with solar panels to provide clean and carbon-free energy. The engineers predict a 70% reduction in CO2 emissions. The leaf-inspired road layout also channels wind which reduces the need for air conditioning in hot weather.

The Danish municipality of Sonderborg has the ambitious goal of aiming to be carbon-free by 2029. The "ProjectZero" plan was launched in 2007 and involves a move towards towards using renewable energy. The plan includes the establishment of on- and off-shore wind farms.

The "ProjectZero" plan is a collaboration between politicians, businesses and the 77,000 people that live in the area. Much of the region lies on the coast and has experienced flooding due to rising sea levels and heavy rainfall. The municipality is already a hub for green technology. Danfoss, a leader in solar energy, and Linak, who make components for wind and solar energy technology are based there.
Spanish architects Infiniski take an eco-friendly approach to design. This involves using recycled and non-polluting construction materials. The basic components of many of their buildings are shipping containers. They are also designed to provide a cooling effect in hot climates and are cheap and quick to build.
Masdar City in the UAE aims to be the world's first planned carbon-free city. Located 10.5 miles from Abu Dhabi, Masdar City was initiated in 2006 and is designed to be a global center for "cleantech" companies.

Based in the desert, there is no shortage of sunlight. Masdar City uses this natural resource; 87,777 solar panels provide the city with carbon-free energy. However, the managers of Masdar City have admitted they are not close to being a carbon-free community.

Initial plans banned automobiles from the city. Driverless pods, known as "personal rapid transit" (PRT) carts, are used by residents. The city is also designed in a way to encourage walking and cycling. Although revised plans have allowed for electric and clean energy cars to be permitted within the city.

One-way of moving towards eco-friendly and carbon-free living is as simple as reducing the size of your home. The "Tiny House Movement" (an example pictured above) is a transition towards building smaller homes and downsizing. Smaller homes, by their nature, have much less cooling and heating costs, and are powered by solar panels on the roof.

Earthships are weird and wonderful eco-friendly homes, built from from natural and recycled materials. They are designed to be "off-grid ready", not needing to rely on external sources of energy or fossils fuels.

Another sustainable approach to living is to build using recycled materials. Designer Gregory Kloehn did this by turning a dumpster into a fully functional home. He "up-cycles" washing machines, tires, bathroom and sun decks.

Another example of the push towards carbon-free living is the Wintles Village, United Kingdom, which features houses which are said to be among the most energy efficient in the UK. Domestic dwellings claimed to be responsible for 27% of the UK's carbon emissions.

The United Arab Emirates (UAE) will not run out of oil any time soon. According to the most recent data set available, the Emirates has proven reserves equivalent to 98 billion barrels – enough for the nation to rank seventh globally.

According to World Bank figures, the UAE consumes 18.4 tons of CO2 per capita per year – nearly four times higher than the global average. But the nation is moving away from crude solutions and swapping them for ones of the eco variety.

In January, Sheikh Mohammed bin Rashid Al Maktoum, the ruler of Dubai and UAE vice president, announced a new energy strategy and $163 billion of investment in alternative energy over the next three decades.

These changes, taking place on a macro level, will gradually transform Dubai. The Emirates’ aim is to produce 50% clean energy by 2050 – 44% of that from renewables – and increase energy efficiency by 40%.

The UAE has already embarked on huge government-funded green housing projects – Masdar City in Abu Dhabi, for example, has funding commitments of $15 billion. But private companies are also playing a part.

Dubai-based developer and civil engineer Faris Saeed is already working on a model of what future “green” communities might look like. His company Diamond Developers has constructed The Sustainable City, a 5-million square foot complex built to consume zero net energy with the potential to go off-grid – the first of its kind in the emirate, the company claims.

Sunshine city

The Sustainable City’s 500 homes, located 18 miles from Dubai City, are powered by solar panels capable of achieving 10 mega-watts at their peak.

Regional expert and author Jim Krane says Dubai’s “300-plus sunny days a year” make solar energy a “very predictable resource.” Yet while the rooftops soak up rays, houses are orientated to avoid direct sunlight inside, keeping interiors cool.

Can the 'City of Wonders' become sustainable?

As part of the community’s award-winning model, all water is recycled on site, the complex is car-free, and the community grows its own vegetables between 11 biome greenhouses.

On top of this, the site features a 161,000-square foot plaza with retail space, offices and eateries.

“We created … a DNA for sustainability where we deal with the social, environmental and economical (at) the same time,” says Saeed.

Buying a slice of sustainable living is not cheap. House prices start at $1 million, but CEO of construction company Diamond Developers Faris Saeed says that two thirds of the homes have been sold, while others are rented.

"We're trying to prove here that you can make your profits ... and still you can do something which you will be proud of," says Saeed, "your kids will be proud of, and all the world will like it."

Saeed says that Dubai’s 2009 financial crisis – in which the city was almost insolvent – was a turning point for Diamond Developers. Subsequently, he decided to build a green development which also made good business sense, launching his concept in 2013.

To do so he borrowed from best practises around the world.

He cites Fujisawa Sustainable Smart Town in Japan, 50km west of Tokyo, where 18 companies have collaborated on the 60 billion yen ($544 million) project, which began to populate in November 2014. The site includes residences, parks and commercial facilities and is also powered by solar panels, with energy distributed via a localized smart grid.

Still in progress, it will complete in 2018 with 1,000 households, designed and built by Panasonic’s PanaHome division, as part of a 100-year sustainability plan.

“We have never claimed that we invented anything here,” Saeed adds of The Sustainable City. “It’s the way of thinking, the creative way of linking things together.”

Going green

To succeed, citizens need to commit to such projects. But it’s possible, even in places that were not built from the ground up to be eco-friendly. Places like Sonderborg, Denmark.

The city has implemented ProjectZero, a plan to transform itself into a zero-carbon locale by 2029. Using 2007 as a baseline, the 76,000-strong population has already cut emissions by 35% by introducing high-tech solutions including electric vehicle charging points, but also education programs to help citizens make greener choices.

Education is also one of Saeed’s goals. He plans to build a school at The Sustainable City to teach future generations about the impact of sustainability. “We developers have a lot of things to do and we have a huge impact we can make,” he argues.

Buying a slice of sustainable living in Dubai isn’t cheap. House prices at The Sustainable City start at $1 million, but so far two thirds of the properties have been sold, while others are rented.

“Developers are afraid always from the extra cost, and people will not afford or people won’t buy their products,” Saeed argues.

“We’re trying to prove here that you can make your profits … and still you can do something which you will be proud of, your kids will be proud of, and all the world will like it.”
