As the world moves to combat climate change, it’s increasingly doubtful that coal will continue to be a viable energy source, because of its high greenhouse gas emissions. But coal played a vital role in the Industrial Revolution and continues to fuel some of the world’s largest economies. This series looks at coal’s past, present and uncertain future.

Will climate and emissions targets really curb China’s coal consumption? Only time will tell

As the world moves to combat climate change, it’s increasingly doubtful that coal will continue to be a viable energy source, because of its high greenhouse gas emissions. But coal played a vital role in the Industrial Revolution and continues to fuel some of the world’s largest economies. This series looks at coal’s past, present and uncertain future.
Something remarkable happened in China in 2014. China’s coal consumption - the highest in the world - appeared to stabilise for the first time in 16 years. Many commentators proclaimed a new era for China’s energy mix and perhaps even the beginning of the demise of coal in China.
As China is the world’s largest greenhouse gas emitter, this was heralded as good news for the climate.
But the future is rather more uncertain. China is a major regional power with a major energy economy. Its primary energy consumption has grown by more than 500% over the past 30 years. China overtook the United States as the world’s largest primary energy consumer in 2010.
Not surprisingly, the world has been watching the role of coal in China’s energy development with considerable interest over the past few decades.
Twin threats: pollution and climate changeIn 2010, China released its 12th Five-Year Plan (FYP), the country’s defining economic plan for 2011-15. It fundamentally changed China’s approach to energy and climate policies.
Instead of broad goals and statements, the plan shifted to specific policy instruments aimed at reducing emissions. It was driven in no small part by domestic environmental concerns centred on smog, air and water pollution.
The 12th FYP established binding targets to reduce energy intensity by 16%, reduce carbon dioxide (CO₂) emissions intensity (emissions per unit of GDP) by 17%, and increase the proportion of non-fossil fuels in the primary energy mix to 11.4% – all by 2015.
These targets were reinforced by the historic US-China Joint Announcement on Climate Change in 2014.
Through the announcement, and its pledge ahead of the Paris climate summit in December 2015, China promised to peak in CO₂ emissions around 2030 (and try to peak earlier), cut emissions intensity by 60-65% of the 2005 level, and source around 20% of its primary energy consumption from non-fossil fuels by 2030. Provided that economic growth is limited to 5.5% (China’s economy grew by 6.9% in 2015), China’s emissions in 2030 would return to close to 2005 levels.
After the Paris Agreement, China announced its 13th Five-Year Plan, covering 2016-20. With a focus on capping energy consumption to within 5 billion tonnes of coal equivalent (capping overall energy use, not only coal use) by 2020 and addressing air pollution, energy intensity will be reduced by 15%, CO₂ emissions intensity will fall by 18%, and the proportion of non-fossil fuels will increase to 15%.
What does this mean for coal?BP’s 2016 Energy Outlook shows China’s fuel mix is changing. The share of coal in primary energy is projected to fall from 66% in 2014 to 47% by 2035. Demand for coal is likely to peak in 2027 and then fall by 0.3% each year over the next seven years.
To compensate for China’s reduced reliance on coal, the share of natural gas is expected to more than double, with the share of non-fossil fuels also increasing rapidly to bridge the gap.
One interesting question is what does this mean for coal-fired power infrastructure in China?
Two main drivers influence the building of new power plants.
The first is growth in future electricity demand. This is influenced by population growth and the intensification of energy use in developing economies, such as China.
The second is “business-as-usual retirement” of infrastructure. This is driven largely by regulatory compliance and competitiveness in the electricity market, as well as a preference to shift to low-carbon sources to assist in meeting emissions reduction targets.
Most power plants approaching retirement age are located mainly in the USA and Europe, as you can see in the chart below. China, on the other hand, has a remarkably young fleet with a median age of 10 years.
And this is where the dilemma emerges. Very few plants are approaching the age of natural retirement in China, even by 2030 when emissions are scheduled to peak.

Given the age of coal-fired infrastructure in China, it doesn’t appear as though business-as-usual retirements will drive a dramatic reduction in China’s coal use.
Increasing climate actionOf course the pledges announced prior to Paris are only part of the story. The Paris Agreement aims to hold warming to well below 2℃ and attempt to limit warming to 1.5℃.
Estimates suggest the Paris pledges would result in warming of 2.7-3.6℃. Accordingly, much greater emissions-reduction efforts are likely to be required to hold global average temperature increase to less than 2℃.
A recent study looked at the implications for global coal-fired power investments (operating, committed and planned) for a 2℃ average temperature rise scenario (in line with the International Energy Agency’s global mitigation scenario).
The investments in recent and new coal-fired power plant capacity are dominated by expansion in Asia, in particular China and India. A global reduction in coal-fired power infrastructure to shift from the business-as-usual scenario to the 2℃ mitigation scenario unsurprisingly would require China to make a significant contribution to this reduction.
Accordingly, China would need not only to reverse its growth trend in installed capacity by 2030, but also decommission some 400 gigawatts of coal-fired infrastructure, approximately equivalent to a third of its capacity, before the end of its useful life.
The implication is that non-OECD countries including China could be asked to carry more of the economic burden to transform the global energy system because these countries will need to prematurely retire cost-effective coal power assets. Questions about whether this is realistic and around compensation for the cost of such early retirements may influence the prospects of addressing the risk of climate change.
A second driver of China’s coal consumption trend is the push to reduce air pollution, in particular damaging pollution known as PM2.5. While BP’s Energy Outlook for 2016 suggests that this will drive the switch from coal to natural gas, in the absence of serious constraints on carbon emissions, energy security drivers may favour the use of coal-derived synthetic natural gas (syngas or SNG).
While this reduces air pollution, the production process is very carbon-intensive. China has made ambitious plans to develop this technology.
With the release of the 13th FYP earlier this year, the energy sector was expecting a limit on total coal consumption and cuts to coal production in order to peak emissions by 2030.
Yet while some production cuts have been announced, precisely how this will play out for coal-fired power infrastructure and actual coal consumption remains to be seen.

What would a global warming increase of 1.5C be like?
The Paris climate conference set the ambitious goal of finding ways to limit global warming to 1.5C, rather than the previous threshold of 2C. But what would be the difference? And how realistic is such a target? Environment 360 reports
How ambitious is the world? The Paris climate conference last December astounded many by pledging not just to keep warming “well below two degrees celsius,” but also to “pursue efforts” to limit warming to 1.5C. That raised a hugely important question: What’s the difference between a two-degree world and a 1.5-degree world?
Given we are already at one degree above pre-industrial levels, halting at 1.5C would look to be at least twice as hard as the two-degree option.

Continue reading...Survey: more Australians want climate action now than before the carbon tax
In April 2011, not long after Julia Gillard was returned to power in the 2010 federal election, I asked a representative sample of Australians about their attitudes to climate policy.
Climate was a water-cooler issue at the time. The carbon tax legislation had been introduced into Parliament in March, paving the way for a subsequent emissions trading scheme.
That scheme bit the dust in 2014 after becoming a hotly debated issue during the rancorous 2013 election campaign, but carbon policy has not had the same high profile during the current campaign. My colleagues and I decided to repeat our survey and see whether attitudes really have cooled on global warming.
Despite climate policy being something of a sleeper issue in this election, our results suggest that concern about the climate is more widespread now than it was five years ago.
We found that 75% of people surveyed believe it to be an important global issue, and 74% see climate as an important issue for Australia.
As to what we should do about it, we found that 57% of people want Australia to act on climate change irrespective of whether other countries do or not. This is significantly more than in 2011, when 50% of people were in this category.
A further 28% in our new survey think that action should be taken only if there were concerted international policy action, whereas just 15% would prefer that Australia take no action at all. When asked why they did not want to proceed, 34% of them stated that they only wanted to proceed if global action was taken.
These are fairly clear indicators that Australians are not complacent about the need for climate action.
What policies do voters want?Both of the major political parties have committed to emissions targets: the Liberals have a target of a 26-28% reduction relative to 2005 levels by 2030, whereas Labor has pledged a 45% cut over the same time frame. Both are modest in comparison with the Climate Change Authority’s recommended cut of 40-60% by 2030 relative to 2000 levels.
As for the policies needed to meet these targets, Labor has proposed an emissions trading scheme, but some details are still vague. The Liberal Party is persisting with its Direct Action plan to “auction” emissions reduction projects to the cheapest corporate bidders.
Our survey, however, suggests that many voters' preferred policy is a mixture, potentially including a carbon tax, an emissions trading scheme and other direct action policies. Some 40% of respondents preferred this policy mix, up from 31% in 2011. Support for carbon taxation or emissions trading as standalone policies both fell relative to five years ago.
When divided according to voting intentions, all groups preferred a policy mix to any of the other choices. This preference was strongest for “unsure voters”, who made up nearly a quarter of our respondents. For Labor and Greens voters, the most favoured second-choice option was a carbon tax, while no single policy (not even Direct Action) came a close second among Liberal voters.
The numbers get even more intriguing when we split them by gender, age and income. We found that 82% of females see the issue of climate change as important at a global level, and the same proportion described it as important at a local level; this was 15 and 16 percentage points, respectively, greater than among their male counterparts. There was a similar 15-point gender difference in the desire to proceed on climate policy irrespective of global action.
This desire for climate policy irrespective of global action was the dominant view in every age group, although we found that it declined among older groups. The 55-59 age group was the weakest in its support for climate action and the most likely (at 36%) to select “no policy” as the desired climate response.
In our 2011 study, higher incomes were associated with less desire for climate policy. This was replicated in 2016, as can be seen in the graph below – note the significant increase in support for “no climate action” among those with salaries over A$110,000.
As these stats show, concern about climate change is relatively steady until we get to the highest income bracket, where it drops off significantly. There are several potential explanations, including the suggestion that those with higher incomes will be less adversely affected by climate change because they can afford to ameliorate its impacts.
But if there is a take-home message for politicians in these numbers, I would suggest it is this: even in those groups with the lowest levels of climate concern, a majority is still worried about the issue and wants to see action.
Perhaps, in the midst of the longest election campaign since the 1960s, it might be worth finding a bit more time to acknowledge that.

It's an agile predator, but a gruesome fate often awaits the dung fly
Wolsingham, Weardale Adult dung flies chew hoverflies like hotdogs, but many fall victim to an insect-eating fungus
Cattle had been sheltering in the lee of the hedge and had spattered the footpath with fresh cowpats. We had to be careful where we put our feet, but the male dung flies, Scathophaga stercoraria, sitting in the centre of these discs of ordure, had no such reservations; these were their courtship arenas. Each suitor, resplendent in golden hairs that glowed in the early morning sunlight, was waiting for the arrival of females – usually found to be in short supply.
Dung flies’ behaviour and their sex lives have intrigued evolutionary biologists. Males vary in size and females tend to choose the largest mates available on the cowpat, with multiple mating being the norm. It’s a situation where large males, which tend to be more fecund, should prosper.

Victoria's renewables target joins an impressive shift towards clean energy
![](https://62e528761d0685343e1c-f3d1b99a743ffa4142d9d7f1978d9686.ssl.cf2.rackcdn.com/files/126852/width496/image-20160616-19921-1w5w1d9.jpg)
The Victorian Labor government has announced an “ambitious and achievable” Victorian Renewable Energy Target (VRET). This target will commit the state to generating 25% of its electricity from renewable energy by 2020, and 40% by 2025.
While details of the VRET are yet to be fully fleshed out, it is set to be based on a similar mechanism to the scheme used in the Australian Capital Territory (ACT), which has managed to sidestep the uncertainty that has plagued the renewables industry in recent years. The ACT deputy chief minister, Simon Corbell, called Victoria’s announcement on Wednesday “a game-changer”.
In fact a key motivation identified by the Victorian energy minister, Lily D'Ambrosio, was “restoring the confidence needed to invest”.
National tallyThe federal Renewable Energy Target (RET) was reduced by 20% following the Warburton Review in 2014. Since then, state and territory governments have announced their own targets to support the industry.
Earlier this year, the ACT announced it would bring forward previous commitments. It is now aiming to meet 100% of its electricity needs by 2020.
In 2014, South Australia announced a 50% target by 2025. More recently, Queensland committed to generating 50% of its energy from renewable sources by 2030.
Based on forecasting by the Australian Electricity Market Operator, these commitments add up to a considerable expansion of renewable energy. In total, these commitments represent 56 terawatt hours (TWh) each year, above baseline generation. Baseline generation is renewable generation that existed before 1997, almost exclusively hydro power.
![](https://62e528761d0685343e1c-f3d1b99a743ffa4142d9d7f1978d9686.ssl.cf2.rackcdn.com/files/126700/width754/image-20160615-14060-1613a3w.png)
The remaining states already have renewable generation and these facilities presumably won’t be torn down. So even assuming that these states don’t build a single new project, in combination with the targets, Australia is headed towards a total of 61TWh above the baseline.
This compares to the current national target of 33TWh. If the states fulfil their commitments, they will deliver almost twice as much renewable generation as the national RET requires.
If we add baseline hydro back into the equation, total renewable energy generation in Australia is set to be at least 77TWh by 2030. Depending on how electricity demand changes, and how rooftop solar is included, Australia is on track to meet 30-35% of its power demand from renewables by 2030.
What does the target mean for coal?Victoria has always been a major exporter of electricity in the National Electricity Market. In 2014-15, it generated more than 55TWh of electricity and exported over 8TWh. Generally, Victoria exports to South Australia, New South Wales and Tasmania (although Tasmania’s flows have been more interesting in recent times).
It is unlikely that Victoria will substantially increase exports. Indeed, it has limited ability to do so. The South Australian government recently announced funding for a study into new interconnection for South Australia to import power when required, and export more renewable energy to other markets.
Consequently, such a significant increase in renewable generation in Victoria – expected to be in the vicinity of 5,400 megawatts – will have dramatic implications for the state’s existing power stations.
An increase in market share of renewables, from roughly 14% today to 40% in 2025, will necessarily come at the expense of market share for existing power stations. And in Victoria that means brown coal, Australia’s most carbon-intensive power source.
The question now is can the brown coal generators collectively survive such a reduction in market share? And if they can’t, who drops out, and when? Or perhaps brown coal can be progressively phased out without too much pain.
This is, however, good news for Australia’s national climate change mitigation commitments. At average Victorian emissions intensity, by the time the 2025 Victorian target is fulfilled, the new renewable generation in Victoria would be avoiding the emission of some 18 million tonnes of CO₂ per year.
National policy implicationsAt the national level, several different policies and pathways have emerged through the election campaign. These includes a national 50% renewable energy target, an emissions trading scheme, a brown coal exit plan and potential modifications to the government’s cap on emissions (known as the safeguard mechanism).
Whatever emerges at the federal level, the Victorian scheme is well adapted to future changes to both the energy market and energy policy developments. Indeed, it is expressly designed to complement national schemes in the long term, and to provide certainty and confidence for investors in the short term.
In response to the VRET, the Business Council of Australia has called for climate policies that are “integrated with broader energy policy”. A decade of policy uncertainty and toxic political debate has thus far prevented this from occurring.
As the Grattan Institute reported earlier this year: “An economy-wide carbon price remains the ideal climate policy. But pragmatism and urgency demand a practical, next-best approach.”
Given the popular support for renewable energy, perhaps this policy is actually such a pragmatic approach.
