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.


Achieving net-zero emissions at the global level, as required to limit warming to 1.5 °C, means both rapid emissions reductions across all sectors as well as a scaling-up of carbon dioxide removal (CDR). As a growing number of countries bring forward national net-zero targets, the questions of how much CDR each nation holds responsibility for, whether CDR transfers should be possible under the Paris Agreement market mechanisms, and how this might affect the years in which different countries should achieve net-zero, become increasingly important.  
This weekend the members of the G7 will meet in the UK, in a year that marks an important deadline for countries to bring forward stronger climate targets. All of the G7 governments, covering roughly half of global GDP and over a fifth of greenhouse gas emissions, have enhanced their targets in the last year. But are these countries and other major economies pulling their weight?  
Deutschland wird seine nationalen Ziele verstärken und geeignete Maßnahmen ergreifen müssen, um die Ziele des Pariser Klimaabkommens zu erreichen. Dies wird laut der Studie von Climate Analytics, im Auftrag von Agora Verkehrswende, erhebliche Anstrengungen im Verkehrssektor erfordern. Auch das bevölkerungsreichste Land der EU wird sich seiner Verantwortung stellen müssen.  
This report provides key carbon budget benchmarks for the energy and industry sectors for Queensland that are consistent with the state playing its role in national and global efforts to limit global mean warming to 1.5°C above pre-industrial.
