14 June 2017, Carbon Brief, The world added a record amount of energy from renewable sources in 2016 and global coal use fell again, according to the 2017 BP Statistical Review of World Energy, published earlier this week. This helped to keep global CO2 emissions flat for the third year in a row, even as energy demand rose. The record 53 million tonnes of oil equivalent (Mtoe) added by non-hydro renewables met a third of the increase in global energy demand. Global coal use fell by 53Mtoe (1.4%) and is now 4% below the 2014 peak. Meanwhile, coal production fell by a record 231Mtoe (5.9%), as massive output declines continued in the US and China worked to reduce overcapacity and combat air pollution. Carbon Brief runs through BP’s new data and highlights some of the key changes in global energy production and use last year. Record renewables Non-hydro renewable energy sources, such as wind and solar, had a record year in 2016, adding 53Mtoe. They were the fastest-growing source of energy, up 14%, in line with average growth of 16% per year over the decade to 2015. Together with nuclear and hydro, low carbon energy supplied more than half of the net increase in global energy demand between 2015 and 2016. Read More here

8 June 2017, The Guardian, Australia’s carbon emissions rise in off-season for first time in a decade. Exclusive: On the eve of the long-awaited Finkel review, analysis shows Australia’s emissions rose sharply in the first quarter of 2017. Australia’s carbon emissions jumped at the start of 2017, the first time they have risen in the first few months of a year for more than a decade, according to projections produced exclusively for the Guardian. Emissions in the first three months of the year normally drop compared with the previous quarter, driven by seasonal factors and holidays. But in something not seen in since 2005, emissions rose in the first quarter of 2017 compared with the last quarter of 2016 by 1.54m tonnes of CO2, according to the study by consultants NDEVR Environmental. The rise was driven by increases in emissions from electricity generation. Government data on greenhouse gas emissions is released up to a full nine months after the end of a quarter. So NDEVR Environmental replicate the government data for the Guardian, releasing it about a month after the quarter finishes. The unseasonal rise in emissions continues a trend of rising national emissions which began in 2014 and which the government’s own modelling suggests will continue for decades to come, based on current policies.

5 June 2017, Renew Economy, Finkel’s fine line through Australia’s testy power politics. It now seems certain that chief scientist Dr Alan Finkel will deliver a range of options for government policy makers when presenting his review to the COAG ministers and leaders this Friday. There will be mention of the emissions intensity scheme, but because a carbon price of any form is not on the menu of this Coalition government, other more “palatable” alternatives will be on offer, including a low emissions target, an option on pairing new renewables with storage or back-up and, possibly, a pathway for regulation. All have their merits. But as in any policy, the devil will be in the detail and the way these schemes are designed – for the future or the past. And it is going to be interesting to see how Finkel presents his case. Will it be his view of what should be done? Or will it be focused on what can be managed in the current political environment? Certainly, there is a growing chorus among politicians and the mainstream media that something should be done. But there is not a lot of thought into what these policies can actually achieve, even though they should obviously seek to meet climate targets and manage the energy transition efficiently and at lowest cost. The problem was that none of the institutions could bring themselves to actually say it: that wind and solar are by far cheaper than coal and gas and any “other low-carbon technologies”. The Australian Energy Markets Commission and the Climate Change Authority reinforced their support for an emissions intensity scheme (EIS), and only saw a low emissions target (LET) as a second-best measure. Once again, those recommendations simply reinforce preconceived ideas, and lousy modelling. Both institutions came out strongly in support of an EIS last year, but as we pointed out at the time, here and here, these positions were based on hopelessly pessimistic modelling inputs on the cost of solar and wind.

22 May 2017, Washington Post, Stop hoping we can fix climate change by pulling carbon out of the air, scientists warn. Scientists are expressing increasing skepticism that we’re going to be able to get out of the climate change mess by relying on a variety of large-scale land-use and technical solutions that have been not only proposed but often relied upon in scientific calculations. Two papers published last week debunk the idea of planting large volumes of trees to pull carbon dioxide out of the air — saying there just isn’t enough land available to pull it off — and also various other strategies for “carbon dioxide removal,” some of which also include massive tree plantings combined with burning their biomass and storing it below the ground. “Biomass plantations are always seen as a green kind of climate engineering because, you know, everybody likes trees,” said Lena Boysen, a climate researcher at the Max Planck Institute for Meteorology in Germany, who led one of the new studies while a researcher at the Potsdam Institute for Climate Impact Research. “But we just want to show that that’s not the complete story. They cannot do that much.” Forests have long been recognized as one of the world’s most important natural carbon sinks, capable of storing large amounts of carbon that would otherwise end up in the atmosphere. Simply preserving the world’s forest resources — and replanting areas that have already been deforested — is viewed as an important step in protecting the climate. But for years, scientists have discussed the idea of going further by using large plantations full of fast-growing, carbon-storing trees to pull extra carbon emissions out of the atmosphere, a strategy sometimes called “afforestation.” But the amount of land and other resources this strategy would require to actually help us meet our global climate goals — namely, keeping global temperatures within at least two degrees of their pre-industrial levels — is completely impractical, according to Boysen’s new study in the journal Earth’s Future, and would require the destruction of huge amounts of natural ecosystems or productive agricultural land.
