14 December 2015, Renew Economy, Hidden gem in Paris deal condemns coal to early demise. When France foreign minister Laurent Fabius brought the gavel down on Saturday night and declared the Paris Agreement on climate change action was sealed, the reaction was almost immediate. Within the conference hall it was greeted with cheers, hugging and great emotion. Outside, the agreement to cap temperature rises “well below 2°C” and as low as 1.5°C signalled a remarkable achievement that had one major implication: the end of the fossil fuel era is nigh. ….But if that is what the fossil fuel industry and the Coalition government are really thinking, then the evidence suggests that they are kidding themselves. One little gem, alerted to me by the Potsdam Institute’s Malter Meinshausen (on the dance floor of the COP after party of all places) puts the agreement in a new perspective. It is this paragraph, article 17, in the decisions text of the deal: “Clause 17. Notes with concern that the estimated aggregate greenhouse gas emission levels in 2025 and 2030 resulting from the intended nationally determined contributions do not fall within least-cost 2 ̊C scenarios but rather lead to a projected level of 55 gigatonnes in 2030, and also notes that much greater emission reduction efforts will be required than those associated with the intended nationally determined contributions in order to hold the increase in the global average temperature to below 2 ̊C above pre-industrial levels by reducing emissions to 40 gigatonnes or to 1.5 ̊C above pre-industrial levels by reducing to a level to be identified in the special report referred to in paragraph 21 below”; OK, now for a quick translation. The world currently emits around 50 gigatonnes of greenhouse gas emissions a year. Even if all the pledges put together by 186 nations before and during the Paris climate talks were enacted, these emissions would grow to around 55 gigatonnes of GHG emissions a year by 2030. But to meet the 2°C target, the world will need to reduce those emissions to 40 gigatonnes a year. And to reach that level, they are likely going to have to reverse direction before 2020. What’s more, if the world does move to that aspirational goal of capping temperatures to 1.5°C above pre-industrial levels, then it is going to have to move a lot faster, and a lot more dramatically than that. That trajectory will be outlined by a new IPCC report due in 2018. Read More here

14 December 2015, The Guardian, Pentagon to lose emissions exemption under Paris climate deal. Armed forces around the world – including US military – will no longer be automatically excluded from including their carbon emissions under national reductions targets. The US military and armed forces of countries around the world will no longer be automatically exempted from emissions-cutting obligations under the UN Paris climate deal, the Guardian has learned. Although the US never ratified the Kyoto protocol, it won an opt-out from having to fully report or act on its armed forces’ greenhouse gas emissions, which was then double-locked by a House national defence authorisation bill in 1999. Under the Paris agreement, countries would not be obliged to cut their military emissions but, equally, there would be no automatic exemption for them either. US officials privately say that the deal adopted on Saturday has no provisions covering military compliance one way or another, leaving decisions up to nation states as to which national sectors should make emissions cuts before 2030.

14 December 2015, Science Daily, Vegetarian and ‘healthy’ diets could be more harmful to the environment, researchers say eating lettuce is ‘over three times worse’ in greenhouse gas emissions than eating bacon. Contrary to recent headlines — and a talk by actor Arnold Schwarzenegger at the United Nations Paris Climate Change Conference — eating a vegetarian diet could contribute to climate change. In fact, according to new research from Carnegie Mellon University, following the USDA recommendations to consume more fruits, vegetables, dairy and seafood is more harmful to the environment because those foods have relatively high resource uses and greenhouse gas (GHG) emissions per calorie. Published in Environment Systems and Decisions, the study measured the changes in energy use, blue water footprint and GHG emissions associated with U.S. food consumption patterns. “Eating lettuce is over three times worse in greenhouse gas emissions than eating bacon,” said Paul Fischbeck, professor of social and decisions sciences and engineering and public policy. “Lots of common vegetables require more resources per calorie than you would think. Eggplant, celery and cucumbers look particularly bad when compared to pork or chicken.” Fischbeck, Michelle Tom, a Ph.D. student in civil and environmental engineering, and Chris Hendrickson, the Hamerschlag University Professor of Civil and Environmental Engineering, studied the food supply chain to determine how the obesity epidemic in the U.S. is affecting the environment. Specifically, they examined how growing, processing and transporting food, food sales and service, and household storage and use take a toll on resources in the form of energy use, water use and GHG emissions. On one hand, the results showed that getting our weight under control and eating fewer calories, has a positive effect on the environment and reduces energy use, water use and GHG emissions from the food supply chain by approximately 9 percent. However, eating the recommended “healthier” foods — a mix of fruits, vegetables, dairy and seafood — increased the environmental impact in all three categories: Energy use went up by 38 percent, water use by 10 percent and GHG emissions by 6 percent.

14 December 2015, Energy Post, Paris emission cuts aren’t enough – we’ll have to put carbon back in the ground. With the Paris climate deal, the world has created the mother of all take-back schemes, writes Myles Allen, Professor of Geosystem Science at the University of Oxford. According to Allen, fossil fuel companies don’t necessarily have to stop producing CO2 – they just need to be required to ensure it doesn’t end up in the atmosphere. #takebackCO2 – start tweeting it now! Courtesy of The Conversation. I wonder how many of the delegates in Paris realise that they have just created the mother of all “take-back schemes”. As a consumer, you may have already come across this sort of deal: if you don’t want to dispose of the packaging of your new sofa, you can take it back to IKEA and it’s their problem. In many places, you can even take back the sofa itself when your kids have wrecked it. For the Paris climate deal to succeed something similar will have to happen, where companies that rely on fossil fuels will be obliged to “take back” their emissions. The agreement reaffirms a commitment to stabilising temperature rises well below 2℃, and even retains the option of limiting warming to 1.5℃ if possible. But it also confirms national targets that do little more than stabilise global emissions between now and 2030. Given those emissions, sticking to within 2℃ will require us to take lots of carbon out of the atmosphere and store it in the ground. The parties to the agreement are, in effect, saying “we’re going to sell this stuff, and we’re going to dispose of it later”. How do I know? Well, peak warming is overwhelmingly determined bycumulative carbon dioxide emissions. To stabilise temperatures at any level, be it 1.5℃, 2℃ or even 3℃, net carbon dioxide emissions must be reduced to zero. Most governments, environmental groups and business leaders now understand this. And it is acknowledged, albeit implicitly, in Article 4 of the Paris agreement, which calls for greenhouse emissions to be “balanced” by carbon sinks some time after mid-century. But we’re unlikely to hit “net zero” emissions before temperatures reach 2℃, and even less likely before they reach 1.5℃. Warming is currently at about 1℃ and rising by 0.1℃ every five to ten years. We could slow the warming by reducing emissions, of course. But if we fail to reduce at the required rate – and the inadequate emissions targets indicate this is the intention – then we will be left with no option but to scrub the excess CO2 back out of the atmosphere in future.
