25 April 2016, The Guardian, The Guardian view on the UN climate change treaty: now for some action. The danger of gala events like the official signing of the climate change treaty at the UN in New York on Friday, crowned with a guest appearance from Leonardo DiCaprio and with 60 heads of state in attendance, is the impression they create that the job is done. It was certainly a spectacular demonstration of global intent to get more than 170 signatures on the deal agreed in Paris in December at the first time of asking; but what matters is making it legally binding. For that, it must be not just signed but ratified by at least 55 countries, and it must cover 55% of emissions. Nor does the Paris deal go far enough. It was only a step on a long, hard road. The targets that each country set themselves do not go nearly far enough. Now the gap between reality and the ambition of holding global warming below 2C needs addressing. In Churchillian rhetoric, this is not the end, nor the beginning of the end, but it is the end of the beginning. Read More here

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.
