Emissions Gap Report 2018

This 9th edition of the UN Environment Emissions Gap Report assesses the latest scientific studies on current and estimated future greenhouse gas emissions and compares these with the emission levels permissible for the world to progress on a least-cost pathway to achieve the goals of the Paris Agreement. This difference between “where we are likely to be and where we need to be” is known as the ‘emissions gap’. As in previous years, the report explores some of the most important options available for countries to bridge the gap.

Introduction

The year 2018 will most likely be the fourth warmest year on record since 1880, with the past five years the five warmest ever recorded (NOAA, 2018). In addition to increased temperatures, 2018 has experienced numerous other climate-related extremes, including devastating storms, floods, heatwaves and droughts, causing thousands of casualties and huge economic losses for citizens, companies and states. While it is difficult to attribute single events to climate change, the patterns are well aligned with the findings of the recently released Intergovernmental Panel on Climate Change (IPCC) Special Report on Global Warming of 1.5°C (IPCC, 2018). The report details how climate variability and extreme events will escalate with increased global temperatures and determines that many impacts will be irreversible, even if temperatures decrease again in the long term. This Emissions Gap Report has benefited significantly from the IPCC Special Report and its underlying studies and scenarios.
