Further decrease in carbon emissions from China

Post by mr friendly guy »

Following up China's decrease in emissions last year it seems to have continued the good work, justifying my view that developing countries eventually "clean up" once they reach a certain level of development.

It Only Took Four Months For China To Achieve A Jaw-Dropping Reduction In Carbon Emissions
BY ARI PHILLIPS POSTED ON MAY 15, 2015 AT 11:45 AM


China is the world’s largest greenhouse gas emitter, so small decreases in its emissions seem like monumental feats when compared to other countries. According to a new analysis, in the first four months of 2015, China’s coal use fell almost 8 percent compared to the same period last year — a reduction in emissions that’s approximately equal to the total carbon dioxide emissions of the U.K. over the same period.

The analysis, published by Greenpeace and Energydesk China, reviewed data from a number of sources, including China’s industrial output, and found that China had reduced its coal output by 6.1 percent in the first four months of 2015. The research team calculated that the drop in coal use translates into a nearly 5 percent drop in domestic CO2 emissions.

Lauri Myllyvirta, an analyst who worked on the Greenpeace report, told RTCC that the report shows that China’s industrial output and thermal power generation are falling while renewable energy sources like hydro, wind, and solar are growing fast.

She said that while some question the accuracy of the data, she has “a high degree of confidence in those statistics because in the current economic situation no government has an incentive to publish falling numbers for industrial growth.”

In 2014, China cut domestic consumption of coal by 2.9 percent, the first drop in more than a decade, with coal production also falling 2.5 percent. China’s carbon emissions also fell last year for the first time in over a decade, dropping 2 percent in 2014 compared to 2013.

While China is rapidly pursuing clean energy technology — with solar growth that dwarfs any other country — and also closing hundreds of coal plants in response to domestic air pollution issues and a shifting fossil fuel landscape, the real reason for the dramatic fall in emissions is likely the country’s sluggish economy. So far in 2015, China’s economy is growing slower than the government’s desired 7 percent pace — a trajectory that puts it on course to have its weakest economic year in a quarter of a century.

But while China’s economic growth may turn around, its coal use will not. Late last year the government announced it plans to cap coal use by 2020, a necessary target to meet its global pledge of peaking greenhouse gas emissions by 2030. Reducing its use of coal, which still generates three-fourths of China’s electricity, is also a key element of China’s renewable energy target of 20 percent non-fossil fuels in “primary energy consumption by 2030.”

As the Wall Street Journal reports, all these factors are coming together in the country’s upcoming overhaul of its power industry, which will be “bad news for coal-fired plants.”
The reforms could throw coal-fired power plants “to the market lions,” which would likely precipitate the closure of countless plants that now represent a glut of coal power in the country and are reliant on tariffs for economic viability.

With China’s domestic energy picture rapidly shifting, it has also continued to engage in strong international rhetoric around climate change in the lead up to the United Nations climate talks in Paris at the end of the year. After entering into a pledge with the U.S. in late 2014 to peak emissions by 2030, this week leaders from China and India — the world’s first and third biggest greenhouse gas emitters — issued a joint statement calling climate change “one of the greatest global challenges of the 21st century.”

The countries, which depend on rapid economic growth for political stability, stopped short of any hard commitments. Rather, they focused on the responsibility of wealthy countries to aid in their efforts to reduce emissions by financing clean energy technologies and by trying harder to reduce their own emissions.
“The two sides urged the developed countries to raise their pre-2020 emission reduction targets and honor their commitment to provide $100 billion per year by 2020 to developing countries,” the joint statement said.

Despite its drop in coal use, China remains a major emitter of the greenhouse gas emissions that drive climate change. In 2013, China was responsible for nearly 30 percent of total global carbon dioxide emissions, a percentage that is rapidly rising. In 2014, for the first time, China’s per capita CO2 emissions surpassed those of the E.U., a trend made even more notable by China’s continued population growth.
A few thoughts

1. Its derived from a Greenpeace report, and while I detest them and their views on GMO, I do agree with them on a lot of aspects on climate change

2. This report talks about declining industrial growth as a cause. From their own link China's industrial output is still growing, just not at previous high levels. What this means is for China to have higher output but lower carbon emissions, they must be using less carbon intensive sources.

3. This is just following the trend last year, where total energy usage grew 3.2%, but coal consumption decreased 2.9% and total carbon emissions declined 1%.

This of course makes me more optimistic for the future.

Re 2. specifically, they are replacing first generation inefficient (and sooty) tech with the newer stuff they have available.

A few years ago the cleaner tech started to take over the installation of new builds, producing a slowly declining average. Now the economics of scale are there (and the worst stuff has passed through even the 2nd hand market to the scrap heap, while the cleaner is starting to enter the 2nd hand market), meaning the average is improving incredibly rapidly without significant behavior change. In a few years it will start to plateau again unless the Party keep driving renewable tech (which it seems they will, since energy independence is valuable to China)

The replacement with more efficient coal plants has been going on for some years. The main contributor to the drop last year seems to be they had a good year with hydro, but we shouldn't overlook a lot of the effort going into renewables. Another thing to note is that a lot of their civilian nukes came online late last year, and a few more are scheduled this year.

If I was a betting man I would predict carbon emissions for China will decrease in 2015 as well. While we are onto fighting climate change, Scientific American are talking up China's tree planting as well.

According to a study published recently in the journal Nature Climate Change, the total amount of carbon stored in all living biomass above the soil has increased globally by almost 4 billion tons since 2003, with China contributing in a notable way to the increase.

The comments section of this Scientific American article is irritating. People are complaining that planting trees won´t be usefull for storing CO2 because the trees will eventually die and the CO2 will be released.

So the Great Green Wall is working after all. I remember how back in 2007, all these journalists were screaming about it being a giant Potemkin garden.

The Great Green wall isn't smooth sailing. Sometimes the trees die out from disease (since there isn't much variety in the planted trees), but it appears not as fast as China can plant them.

I remember CNN talking about Beijing becoming a desert with dust storms etc. Shortly after I read up and found that the desertification process is being reversed, albeit slowly. Then CNN stopped talking about it. :D I think they switched to Beijing's smog problem.

The chinese are also building a shitload of nuclear power plants (I think they are approaching 400, the newer ones largely Westinghouse AP1000s, which are modular-prefab designs)

53 either built, being built or already approved.
Experts have warned that China will struggle to meet its target to put 58 gigawatts of nuclear power into commercial operation by the end of 2020, but Zhang said the quick approval of new projects this year could put the country back on track.

The number of reactor units in operation, under construction or already approved now amounts to 52. They would bring installed capacity up to 53 GW once they were completed, Zhang said.

I expect the number will come close to 400 once they get enough trained personnel around (say 2040-2050)?
