Climate Tipping Points Insights For Effective Policy Action

This report reviews evidence that overshooting 1.5°C may push the earth over several tipping points, leading to irreversible and severe changes in the climate system. If triggered, tipping point impacts will rapidly cascade through socio-economic and ecological systems, leading to severe effects on human and natural systems and imposing important challenges for human adaptation.

This report reviews evidence that overshooting 1.5°C may push the earth over several tipping points, leading to irreversible and severe changes in the climate system. If triggered, tipping point impacts will rapidly cascade through socio-economic and ecological systems, leading to severe effects on human and natural systems and imposing important challenges for human adaptation. Of particular concern are the likely collapse of the West Antarctic and Greenland ice sheets and the abrupt melting of permafrost grounds in the Arctic, which would result in additional sea-level rise and greenhouse gas releases, leading to more warming. Based on the most recent science and consultations with renowned experts, Climate Tipping Points: Insights for Effective Policy Action argues that it is no longer appropriate to consider the risk of crossing tipping points as low-probability. Overshooting 1.5°C may likely lead to irreversible and severe impacts, which must be avoided, heightening the urgency to drastically reduce emissions within this decade. The report calls for a shift in how tipping points are treated in climate policy today and provides recommendations on how climate risk management strategies can better reflect the risks of tipping points in the areas of mitigation, adaptation and technological innovation.

This report provides a synthesis of the OECD Net Zero+ project, covering the first phase of an ongoing, cross-cutting initiative, representing a major step forward for an OECD whole-of-government approach to climate policy.

This report explores how institutional investors can apply risk-based due diligence as recommended by the OECD Guidelines for Multinational Enterprises on Responsible Business Conduct and help them prevent and mitigate adverse climate impacts associated with their investee companies on society and the environment.

This report addresses the urgent issue of climate-related losses and damages. Climate change is driving fundamental changes to the planet with adverse impacts on human livelihoods and well-being, putting development gains at risk.

The Climate Action Monitor is a key publication of the International Programme for Action on Climate (IPAC). It provides a synthesis of climate action and progress towards net-zero targets for 51 OECD and OECD partner countries. This year's edition presents a summary of information on greenhouse gas emissions, an assessment of climate-related hazards and recent trends in climate action. Directed towards policymakers and practitioners, the findings suggest that without increased ambition and a significant expansion in national climate action, countries will not be able to meet the net-zero challenge.

Greenhouse gas concentrations are rapidly increasing and as a result, fundamental economic transitions are needed to limit global warming. This essential book examines the climate and energy policies of selected jurisdictions in Europe and East Asia that have vowed to become carbon neutral.
