Little chance of global emissions decreasing.
Remember the meme which was that “Australia needs to show some leadership by doing it’s bit.”
The Australian target (for the current Government) is that we will be reducing our CO2 emissions by 28% by 2025/30, or whenever, and how the other sides say that’s nowhere near enough.
The current World total CO2 emissions have cracked 40 Billion tonnes per annum, and that’s end of 2014, so at the expected rate of rise, it’s now closer to 42 Billion tonnes.
The Australian total is (around) 550 Million tones, so that’s 1.3% of that World total.
So, with a 28% cut, that will take it down to (around) 400 Million tonnes, a cut of 150 Million tonnes, by 2025/2030, whenever, and that’s a deep and significant cut.
China is constructing one new large scale (new technology) coal fired power plant at the rate of one every seven to ten days, still, as it has been for almost 8 years now.
So, at that rate of construction, and the added CO2 emissions from them, Australia’s targeted cut in 10 to 15 years is totally and utterly negated by China every 11 weeks.
Makes you think eh!
Oh, and Labor, (nyahh nyahh! we’re better than you) well, their target is 50%, so that’s negated in total by China in 19 weeks, and The Greens, (nyahh, nyahh! we’re better than all of them) well their target of 100% will be negated by China in 7 Months.
And that’s just from coal fired power generation.
Now, I wonder! Is that showing leadership, because it sounds more like futility to me!

I read yesterday that in the USA, 2 nuclear plants are to be closed in Illinois I think, because they are no longer economic, because of power from cheap natural gas, and the government is refusing to give them subsidies on the basis they don’t emit CO2.
As fracking spreads across the globe, Natural gas will be used more and more for power generation. Making nuclear and ‘green’ power less economic in most places.

Nonetheless:
CH4 (ie. methane or LNG) + 2O2 > CO2 +2H20 + heat
Between 10%-15% more efficient in generated heat for equivalent CO2 emissions than the new USC coal plants but about 1.8x as expensive.
Here is an example of optimism.
China’s Carbon Emissions May Have Peaked, but It’s Hazy 3 Apr 16

Ian,
‘A fuel price comparison based on equivalent energy content ($/MMBtu) does not reflect differences in energy conversion efficiency (heat rate) among different types of generators. Gas-fired combined-cycle units tend to be more efficient than coal-fired steam units. The second tab shows coal and natural gas prices on an equivalent energy content and efficiency basis. For the fifteenth consecutive month, the price of natural gas at Henry Hub was below the price of Central Appalachian coal on a $/MWh basis. The spread between the two prices increased significantly in March 2016, mainly due to the large decrease in the price of natural gas at Henry Hub. The price of natural gas at New York City on a $/MWh basis was below the price of Central Appalachian coal for the first time in three months, with the spread between the two prices increasing significantly due to the decrease in the price of natural gas at New York City.’
