18 April 2016, The Conversation, Australia’s carbon emissions and electricity demand are growing: here’s why. Australia’s greenhouse gas emissions are on the rise. Electricity emissions, which make up about a third of the total, rose 2.7% in the year to March 2016. Australia’s emissions reached their peak in 2008-2009. Since then total emissions have barely changed, but the proportion of emissions from electricity fell, largely due to falling demand and less electricity produced by coal. But over the last year demand grew by 2.5%, nearly all of this supplied by coal. In 2015 I wrote about concerns that Australia’s electricity demand and emissions would start increasing again. This has now come true. So what’s driving the trend? Why did demand fall? To understand this trend we need to look at data from Australia’s National Electricity Market (NEM), which accounts for just under 90% of total Australian electricity generation. While the NEM doesn’t include Western Australia or the Northern Territory, it has much better publicly available data. The chart below shows electricity generation from June 2009 to March 2016.

 The most important things to note are that, until February 2015, overall generation fell and the amount of electricity supplied by coal also fell. These two trends are closely related. Read More here

12 April 2016, Carbon Brief, In-depth: Experts assess the feasibility of ‘negative emissions’. To limit climate change to “well below 2C”, as nations agreed to do in Paris last December, modelling shows it is likely that removing carbon dioxide emissions from the atmosphere later on this century will be necessary. Scientists have imagined a range of “negative emissions” technologies, or NETs, that could do just that, as explained by Carbon Brief yesterday. But are any of them realistic in practice? Carbon Brief reached out to a number of scientists, policy experts and campaigners who have studied both the necessity and feasibility of negative emissions. We sent them the following identical email: The Paris Agreement calls for “holding the increase in the global average temperature to well below 2C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5C above pre-industrial levels”. However, as the IPCC AR5 report showed, the majority of modelling to date assumes a significant global-scale deployment of negative emissions technologies in the second half of this century, if such temperature limits are to be achieved.

1) What negative emissions technologies offer the most promise – and why?
2) Is it feasible to achieve the scale of deployment required to meet the aims of the Paris Agreement? If so, how? If not, why?

These are the responses we received, first as sample quotes, then, below, in full: Read More here

23 March 2016, Renew Economy, Turnbull’s sleight of hand on clean energy investment. Prime Minister Malcolm Turnbull has put his own stamp on clean energy investment in Australia, dumping Coalition plans to scrap the Clean Energy Finance Corporation, but announcing new plans to essentially de-fund the Australian Renewable Energy Agency and replace it with a new “Clean Energy Innovation Fund.” The retention of the CEFC will be welcome and signals a potential shift from the anti-renewable policy stance of the Abbott regime that preceded him. But the move to de-fund ARENA and create a “new” fund using money already allocated to the CEFC is nothing but a sleight of hand, and an elaborate ruse by Turnbull to save more than a $1.3 billion and get his new pet-word “innovation” included in a financing scheme. It may also be designed to meet Australia’s Paris commitment to invest “new money” in clean energy innovation. But the move may back-fire, because although the new set-up will continue to support near commercial projects, the technologies and ideas at the formative stage of the innovation process may be left stranded, without funding. According to the former chairman of ARENA, Greg Bourne, Australian innovation may move overseas to get the necessary support. So much for the innovation nation. The Turnbull government has been showing less interest in ARENA, and its cost to the budget, and over the last few months has allowed not renewed contracts for directors, and allowed it to narrow to a single director, the head of Greg Hunt’s environment department. ARENA will continue to manage its current projects, and complete its $100 million funding program for large scale solar projects. But after that its funding will be stopped and it will effectively be morphed – along with its staff – into an annexe of the CEFC and the new fund. Under the new plan hatched by Turnbull and Hunt, ARENA’s grants-based funding strategy will be replaced by “innovative” finance such as debt and equity funding – effectively lending money and buying shares in the investments. Read More here

18 March 2016, Climate News Network, Emissions standstill boosts Paris hopes. The link between global economic growth and emissions growth has been further weakened as greenhouse gas levels show no increase for the second year in succession. The world continued to make progress towards a low-carbon economy during 2015, according to analysis by the International Energy Agency (IEA). It says analysis of preliminary data for the year reveals that global energy-related emissions of carbon dioxide − the largest source of man-made greenhouse gas emissions − showed no increase for the second year in a row.The IEA announcement will be doubly welcome as some Arctic temperatures continue to warm bizarrely. It comes a day after reports from Fort Yukon in Alaska said temperatures there had reached up to 10°C higher than expected for this time of year. Fatih Birol, the IEA’s executive director, said of the emissions report: “The new figures confirm last year’s surprising but welcome news. We now have seen two straight years of greenhouse gas emissions decoupling from economic growth. Landmark agreement  “Coming just a few months after the landmark COP21 agreement in Paris, this is yet another boost to the global fight against climate change.” Significantly, the global economy continued to grow in 2015 by more than 3%, which the IEA says is further evidence that the link between economic growth and emissions growth is weakening. In more than 40 years, it says, there have been only four periods in which emissions stood still or fell compared to the previous year. Three of those – the early 1980s, 1992 and 2009 – were associated with global economic weakness. But the recent stall in emissions comes amid economic expansion. According to the International Monetary Fund, global GDP grew by 3.4% in 2014 and 3.1% in 2015. The IEA says global emissions of CO2 stood at 32.1 billion tonnes in 2015, having remained essentially flat since 2013. Its preliminary data suggest that electricity generated by renewables was critical, accounting for around 90% of new electricity generation in 2015. And wind alone produced more than half of new electricity generation. Read More here
