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 contributions of single greenhouse gas emitters to country-level climate change are generally not disentangled, despite their relevance for climate policy and litigation. Here, we quantify the contributions of the five largest emitters (China, US, EU-27, India, and Russia) to projected 2030 country-level warming and extreme hot years with respect to pre-industrial climate using an innovative suite of Earth System Model emulators.  
This report identifies 40 indicators across key sectors that must transform to address the climate crisis, and assesses how current trends will impact how much work remains to be done by 2030 and 2050 to deliver a zero-carbon world in time. It also outlines the required shifts in supportive policies, innovations, strong institutions, leadership and social norms to unlock change.  
In December 2020, the Federal Government projected Australia’s emissions would reach roughly 22% below 2005 levels by 2030 which falls short of its 26-28% Paris Agreement target. We anticipate the Federal Government will soon announce an increase in projected emissions reductions for 2030 under a business-as-usual scenario. This report reveals virtually none of the likely reductions are a result of the Federal Government’s own policy.  

Projects

The Paris Agreement commits all countries to take ambitious steps to guarantee a low carbon future. This requires individual national governments to submit more ambitious emission reduction targets. In support of this urgent need to translate global trajectories to be in line with the Paris Agreement, this project, founded by the IKEA Foundation, shows how a group of countries, across all regions and development spectrum can update their NDCs to be in line with the Paris climate goals.  
The project aims to investigate how changes in land cover and land management can help to meet the mitigation and adaptation objectives of the Paris Agreement, as well as the Sustainable Development Goals. The project partners findings will be disseminated through a number of tools, events and products and by closely involving stakeholders and policy-makers, with the aim to support sustainable land use decision-making.  
COP21 Results and Implications for Pathways and Policies for Low Emissions European Societies The Paris Agreement represents an important new strategic context for EU climate policy. Analysing the implications of this new context requires an interdisciplinary approach, combining analysis of the evolution of the international climate regime as well as of NDCs and their socio-economic implications.  
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
