What is the world’s remaining “carbon budget”? Or, how much more CO2 can the Earth take before we know we’ll miss our 1.5oC (and 2oC) goals for 2050. Making those calculations is not easy and IPCC benchmark estimates inevitably include levels of uncertainty in the final answer. Kasia Tokarska at the ETH Zurich Institute and Damon Matthews at Concordia University summarise their research that narrows down that uncertainty, making life a little … [Read more...]
IEA’s WEO 2019 scenarios won’t hit the Paris targets, again. It must start telling us what will
As always, the energy world is abuzz with reactions to the IEA’s annual World Energy Outlook, published yesterday. As always, it’s getting plenty of criticism from those who say it lacks ambition, and in doing so will again get quoted to justify support for continued reliance on fossil fuels, explains Kelly Trout at Oil Change International. The IEA’s most ambitious pathway, the Sustainable Development Scenario (SDS), gives a 66% chance of … [Read more...]
Global ‘sectoral’ treaties, legally binding corporate targets can turn around emissions rise
The United Nations Framework Convention on Climate Change started with a top-down legally binding Kyoto Protocol and ended up with a bottom-up ‘self-determined’ voluntary Paris Agreement, says Chandra Bhushan. As a result, nobody has the tools to drive global collective action to combat climate change. The author says that’s why emissions are at record levels. He recommends international ‘sectoral’ treaties to achieve real transition in energy, … [Read more...]
New tool to show whether companies’ climate strategy matches their public ambitions
By now we’re used to stats that show what would happen if everyone in the world had the same carbon footprint as a European, or an American, someone in China, or indeed anywhere. According to the consultancy right. based on science, they have now created a way of modelling the same projections, except for specific companies. The model also number-crunches a company's climate strategy to work out whether they are going to help or hinder the race … [Read more...]
Why we can’t reverse climate change with negative emissions technologies
The United Nation’s panel on climate change said that technologies to remove CO2 will be necessary to limit global temperature rise to only 1.5oC. But these techniques are largely unproven, and the technical, economic and environmental barriers of negative emissions technologies (NETs) are very real, states Howard J. Herzog, Senior Research Engineer at Massachusetts Institute of Technology and a leading expert in CO2 capture and storage. … [Read more...]
Europeans ‘not very worried about climate change’
The latest UN Intergovernmental Panel on Climate Change report is a wake-up call for the need to act quickly on greenhouse gas emissions. But research from the European Social Survey suggests European attitudes towards climate change could be hard to shift, says Ed Grover, senior communications officer at City, University of London.

8 things you need to know about the IPCC 1.5˚C report
In its landmark report released today on global warming, the UN Intergovernmental Panel on Climate Change (IPCC) says urgent and unprecedented changes are needed to stop global temperatures from rising by over 1.5˚C – but it is possible. The report makes it clear to governments and businesses that limiting warming to 1.5˚C is imperative, says Kelly Levin of World Resources Institute: “Now it’s time for them to step up to the challenge.” … [Read more...]
Dutch court’s climate ruling may force other states to cut emissions – or else
States have a duty of care towards their citizens that the absence of a global climate treaty does not take away, argues Professor Arthur Petersen from University College London. A recent court ruling in the Netherlands sets a precedent for national judges to directly use climate science to find governments liable for inadequate action on climate change, he says. The ruling's biggest impact may be outside the Netherlands. … [Read more...]
