Mitigation Scenarios and Pathways

We explore the greenhouse-gas emission reductions necessary to achieve long-term global climate goals, such as holding warming below 1.5 and 2°C warming relative to pre-industrial levels. Analysing emissions scenarios from energy-economic models and other sources with coupled carbon-cycle/climate models leads to globally “allowed” ranges of emissions for different greenhouse gases, air pollutants and sectors, as well as associated time- and pathway-dependent mitigation costs and technology portfolios.

COP23 briefing - There has been much talk of "Blue Carbon" in the Bonn climate negotiations. But what does it really mean? This briefing sets out the issues and finds that the use of blue carbon to offset and hence effectively avoid required emission reductions in other sectors would undermine our ability to limit temperature rise to 1.5°C.  
One of the world’s leading climate experts says Australia needs to aim for 100 per cent renewables within two decades as part of its efforts to meet climate targets, and it stands to reap enormous economic – and environmental – benefits if it does. Coverage of Climate Analytics' CEO Dr Bill Hare's talk at Keith Roby Memorial Lecture at Murdoch University in Perth, Australia.  
Less than two weeks ago, Alan Finkel told the Australian Senate his landmark report would help Australia meet the commitments it made in Paris to reduce its economy-wide emissions by 28% below 2005 levels by 2030. But his recommendations on the future of the National Electricity Market, released today, appear to fly in the face of those very commitments. With comments from Climate Analytics' Bill Hare.  
A pact by almost 200 nations to slash greenhouse gases used in refrigerators and air conditioners will likely fall short of governments' hopes of averting a full half-degree Celsius (0.9 Fahrenheit) of warming this century, scientists say. Michiel Schaeffer of Climate Analytics estimates "around 0.2 degree Celsius (0.36F) by 2100" of avoided warming.  
A new Climate Analytics report, released by The Climate Institute today, looks at the implications of the 1.5°C warming limit in the Paris Agreement for Australia, and, in the light of the severe environmental impacts it faces, emphasises the urgency of ramping up climate action.  
A new analysis of the scientific and policy aspects of the 1.5°C temperature limit in the Paris Agreement’s long-term temperature goal has identified a number of important areas that require more scientific research.

There have been proposals for the UNFCCC to adopt a dual-term greenhouse gas accounting standard: 20-year GWPs alongside the presently accepted 100-year GWPs. It is argued that the advantage of such a change would be to more rapidly reduce short term warming and buy time for CO2 reductions. This briefing shows why these changes would be counterproductive and the benefits overstated.  
The Finkel Review was an opportunity to propose a science-based approach to the short and long-term development of Australia's electricity sector consistent with the low-carbon transformation required to meet the goals and obligations of the Paris Agreement. Unfortunately, should the government accept the minimum electricity sector pathway suggested by the Finkel Review, Australia would very likely not be able to meet its obligations under the Paris Agreement, which calls for countries to adopt measures to hold global warming well below 2°C and limit this to 1.5°C.  
A new analysis of the scientific and policy aspects of the 1.5°C temperature limit in the Paris Agreement’s long-term temperature goal has identified a number of important areas that require more scientific research. The analysis, written by a team of scientists who have published key research papers on the science, impacts and policy aspects of the 1.5˚C limit, is a centrepiece of a collection by Nature Climate Change, Nature Geoscience and Nature on 'Targeting 1.5°C'
