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.

The Intergovernmental Panel on Climate Change (IPCC) recently published its Special Report on 1.5°C (SR15) to guide implementation of the Paris Agreement. Governments are tasked with developing long-term low emission sustainable development strategies (LT-LEDS) in line with the 1.5°C goal, and are invited to submit them by 2020. This briefing lays out the key findings of the IPCC SR15 that inform governments in their task to develop and submit LT-LEDS, and inform the continuous scaling up of near- and mid-term action and targets, including in Nationally Determined contributions (NDCs), in line with the ratcheting-up mechanism enshrined in the Paris Agreement.  
Together with the Australian Conservation Foundation, we have been analysing Australia’s emissions profile and policies. This factsheet focuses on Australia’s vehicle fleet and outlines how it compares with other countries, breaks down the main sources of vehicle emissions and evaluates whether there are policies in place to decarbonise the sector.  
The European Union‘s targets and policies are not yet compatible with the Paris Agreement’s 1.5°C limit. This report, the second country assessment in the Climate Action Tracker's Scaling Up Climate Action Series, analyses areas where the European Union could accelerate its climate action. The report illustrates GHG emissions reductions from such actions, along with other benefits.  
With the Australian Conservation Foundation, Climate Analytics has been analysing Australia's emissions profile and policies. We have created some graphic factsheets that illustrate where Australia is compared with other countries, and clearly show how far behind Australia is compared to other major economies in terms of emissions and policies.  
Climate Analytics’ submission to the Talanoa Dialogue summarises the latest scientific findings relating to the 1.5°C limit. It outlines what climate impacts are being experienced around the globe at the current level of warming of around 1°C, such as extreme weather events, more intense tropical cyclones, impacts on oceans systems and health. It also discusses the benefits of the 1.5°C limit in terms of avoided impacts, especially on the most vulnerable communities, and what is needed to limit warming to 1.5°C.  

Projects

COP21 Results and Implications for Pathways and Policies for Low Emissions European Societies  
Science and policy to assist and support SIDSs and LDCs to negotiate a strong international climate regime, enabling low carbon development and supporting adaptation needs.  
Implemented under a collaborative framework, this project is designed to provide specific analytical, scientific and strategic information and support to strengthen the capacity of Least Developed Countries (LDCs). Project Period: 2011 - 2012  
PREVENT is built around a team of experienced climate scientists and analysts, whose objective is to provide science, policy, strategic and analytical support for delegations of the LDCs and SIDS, backed by science-based models to assess and synthesize climate science. Project Period: 2008 - 2011
