Solar radiation modification (SRM), is presented by some as an option that may help to limit global temperature rise. However, SRM cannot address the root causes of anthropogenic climate change – the continued emissions of greenhouse gases. Investing precious time and resources in this critical decade to explore SRM technologies distracts from the urgent need to step up mitigation efforts to halve emissions by 2030.  

This report examines the implications of committed and proposed developments in the LNG and coal mining sectors for reform of Australia's Safeguard Mechanism.  

Based on scenarios underlying the IPCC's 6th Assessment Report, in this paper we construct a suite of scenarios that combine the following elements: (a) two quantifications of a moral claim to the remaining carbon space by South Asia, and Africa, (b) a 'highest possible emission reduction' effort by developed regions, and (c) a corresponding range for other developing regions. Our findings raise important questions of perspectives on equity in the context of the Paris Agreement including on the critical importance of climate finance.  

Considering cryosphere and warming uncertainties together implies drastically increased risk of threshold crossing in the cryosphere, even under lower-emission pathways, and underscores the need to halve emissions by 2030 in line with the 1.5 °C limit of the Paris Agreement.  

This briefing summarises the latest science on 1.5°C including from the Intergovernmental Panel on Climate Change, the International Energy Agency and other key reports.  

This fourth and final ZERO IN report looks at how cutting emissions this decade can limit temperature rise and other climate impacts in the near-term. It looks back to what was set out by governments in the Glasgow Climate Pact and unpacks what “enhanced mitigation ambition …. in this critical decade” must look like, based on the latest IPCC science.  

Limiting global warming to 1.5°C requires transforming almost all systems, from how we power our economy and build our cities to how we feed a growing population and manage our land. This report provides an overview of how we are collectively doing in addressing the climate crisis.
