The world can learn from China




China's carbon intensity has declined by 46% compared to 2005, already exceeding the 2020 target.

China's Policies and Actions for Addressing Climate Change helps all interested people fully understand China's policies and actions, their performances, and effects in addressing climate change since 2017. 

Non-fossil energy accounted for 13.8% of primary energy consumption, which will be reduced more. Afforestation and forest protection continued in China and the ability to adapt to climate change has been continuously enhanced.

The continued improved institutional mechanisms in addressing climate change have increased the awareness of climate change in the whole society.

The technology changes according to the challenges.  China has some unique technologies which can be learnt by the world and help other developing countries to get inspired and take measures.

1.    China’s solar highway

In late-2017, China opened its 1km solar highway in the Shandong province’s capital Jinan, south of Beijing.




It spans 5,875 sqm and is capable of generating up to 1GWh every year – enough to power 800 homes.

However, the Chinese government plans to use the electricity created by its solar highway to power street lights, billboards and CCTV cameras, as well as to heat the road's surface to melt any snow that gathers on it.

In its first 14 weeks in operation, the road generated 96MW of energy.


2.    Forest City


The world's first “Forest City,” created to fight pollution, is now under construction in Liuzhou, Guangxi Province, China.

Designed by Stefano Boeri Architetti, a team that develops green projects all around the world, the futuristic Forest City will be home to a community of about 30,000 people.

This city will run on renewables and absorb nearly 10,000 tons of CO2 and 57 tons of pollutants yearly.

December 30th, 2017 by Steve Hanley. China has opened a 1-kilometre long solar road in Jinan, the capital of Shandong province south of Beijing. 
The two-lane road covers 5,875 square meters and can generate up to 1 million kilowatt-hours of power annually — enough to power 800 Chinese homes, according to XinhuaNet.

3.    The first International Bamboo Architecture Biennale

Place: Baoxi, Zhejiang province
Motive: a showcase of the fast-growing plant’s possibilities
Year completed: 2016

In 2016, the first International Bamboo Architecture Biennale called many international architects to the heart of rural China. They erected a permanent structure made of bamboo.

The installations are a youth hostel, a ceramics museum and a bamboo bridge with plans to turn them into a hotel and learning centre for visitors.

Amid the country’s hard-edged, smoggy cities made from concrete, the bamboo structures are a reminder of the traditional building material’s strength, versatility, sustainable qualities and elegant aesthetics, and they’ve helped to breathe new life into the small town of Baoxi.


4.    Fighting desertification

Place: Gobi Desert’s border
Motive: 100 billion trees to stop the desert from spreading
Status: underway with expected completion in 2050


China is fighting desertification, which is when land becomes increasingly dry, destroying plants and driving out wildlife.

The main cause of this is the Gobi Desert’s encroachment into arable areas due to sandstorms. The country has devised an unlikely way of fighting back: trying to plant 100 billion trees along the Gobi’s 4,500-kilometre border.

Billions of trees have already been planted, in an extremely large area known as the Great Green Wall.

The Problem

Although many scientists are sceptical that planting trees will make a difference, there don’t appear to be any plans to change the programme, which started in 1978 and is expected to go on until 2050.


5.    The world’s largest floating solar farm


Place: Huainan, Anhui province

The world’s largest floating solar farm
Year completed: 2017

Anhui province’s symbol of clean energy wasn’t always so clean: the world’s largest floating solar farm started out as a coal mine. 

When the mine became flooded with groundwater, the government built an artificial lake there instead. Now that lake floats with about 120,000 solar panels, which can power up to 15,000 homes. 

This transformation from coal mine to solar farm jibes with China’s general direction of investing in clean energy projects. It’s not the cutest solar farm in the country, however – that honour would have to go to the panda power plant in Shanxi province’s Datong, which, yes, resembles China’s national treasure when seen from above.

6.    Sun Commune

Place: Lin’an, Zhejiang province
Purpose: farm and agricultural education centre
Year completed: 2016


Sun Commune, an initiative on the rural outskirts of Hangzhou, might just have the happiest pigs in the world.
There, at the foot of scenic mountains, they bask in a spacious stay with a handsome thatched roof and a pool in their large backyard for swimming. 
But space isn’t just for the pigs. There’s a learning centre nearby, which helps to promote the countryside to urbanites – adults and children alike – as an attractive place to live and work. The centre is a modernist architectural marvel in this rice field setting: a ring frame is covered in white canvas, with an open-air deck in the middle. 
It serves as an overnight camp for schoolchildren, who get to experience something different from their city lives in Hangzhou and Shanghai.

7.    Artificial moon in China 

China is planning to launch its own ‘Artificial Moon’ by 2020 to replace streetlamps and lower electricity costs in the southwestern city of Chengdu. The illuminated satellite would be eight times brighter than the real moon, it will be part of the country’s growing ambition in space. 

How ‘the Fake moon’ would work? 

Chinese scientists plan to send three artificial moons into space in the next four years, and the moons--- made from reflective material like a mirror—are expected to orbit at 500 kilometers above the Erath and light up an area with a diameter of 10 to 80 kilometres. Aerospace science and technology microelectronics system research institute corporation which developed the project, said the illuminating satellite would provide a “dusk-like glow”. 

The satellite brightness and service time are both adjustable and the accuracy of the lighting can be controlled within tens of meters. Three artificial moons would operate alternately in order to significantly infrastructure electricity consumption, especially during winter.

What is the purpose behind this project? 

The reason why China creating fake moons simply to save money, China officials stated that putting a fake moon in space could actually end up being cheaper than paying street lights.

 An area of 50sq km could save up to 1.2 billion yuan a year in electricity charges. Electricity at night is very expensive, so having free illumination for up to 15 years, it might work out better economically in the long term. 

It could also “illuminate blackouts areas” in any natural disaster event like an earthquake. 


How it would be possible? 

Scientifically, it's viable the fake moon would have to be permanently in orbit over Chengdu - a relatively tiny area when you look at the Earth from space, that would mean it would need to be a geostationary orbit, which is about 37,000 km from the earth. 

And if you want to light up an area with an error of say 10km even if you miss by one 1ooth of a degree you’ll have the light pointing at another place. And to have any impact from that distance, the mirror would have to be truly colossal. 

Would a fake moon cause a lot of light pollution? 

Fake moons will cause much more light pollution. The moon would significantly increase the night-time brightness of an already light-polluted city, creating problems for Chengdu's residents who are unable to screen out the unwanted light. It will disrupt the night cycle of nature and this could possibly affect animals. 

The idea of a fake moon 

The idea for the man-made moon originated from a French artist who imagined hanging a necklace made of the mirror in the sky to light up the streets of Paris at night. 

This is not a first time a space mirror to create daylight at night has actually been tried before, Russia attempted to launch a 25- meter “space mirror” but the project was put off in 1999. 

Don't you think that climate change needs more awareness? Would you wait for governments to react? Or do you want to contribute to save our home- 'the Earth'.
