In this work we present two unit-level decommissioning schedules that are aligned with a Paris Agreement compatible CO2 emission reduction pathway. Both of these schedules require 4.2 GW of coal capacity to be retired each year, and units currently under construction would only be able to operate for four years at the most.  

Shifting energy supply in South Asia and South East Asia to non-fossil fuel-based energy systems in line with the Paris Agreement long-term temperature goal and achievement of Sustainable Development Goals  

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.  

Germany needs to phase coal out of its electricity sector by 2030 to meet its obligations under the Paris Agreement. This is earlier than the dates discussed so far by the Coal Commission, a body established to come up with a coal exit plan by the end of 2018. If Germany follows the Paris Agreement compatible pathway we propose here, it can also make significant steps towards meeting its 2020 emission reduction targets – something seen as impossible at the moment. Under a planned and structured coal phase out, energy security and reliability of electricity supply is not expected to be a major concern and will be manageable. As well as reduced health impacts, a coal exit from electricity generation by 2030 in Germany will bring added benefits in job creation, helping to smooth the transition to a zero-carbon energy system.  

Limiting global warming to 1.5 or 2.0°C requires strong mitigation of anthropogenic greenhouse gas (GHG) emissions. Concurrently, emissions of anthropogenic aerosols will decline, due to coemission with GHG, and measures to improve air quality. However, the combined climate effect of GHG and aerosol emissions over the industrial era is poorly constrained. This study shows the climate impacts from removing present-day anthropogenic aerosol emissions and compares them to the impacts from moderate GHG-dominated global warming.  

Stopping black carbon will not buy time for global warming, new study shows  

The fifth phase of the Coupled Model Intercomparison Project uses four representative concentration pathways (RCPs) that span the literature range of total anthropogenic radiative forcing, but not necessarily of each single forcing agent.
