Each edition of the Frontiers report introduces selected emerging environmental issues that present distinct challenges and require tailored solutions. These issues have...

The 20th century was a period of unprecedented ecological change, with dramatic reductions in natural ecosystems and biodiversity and equally dramatic increases in people and...

If the temperature increase is to be kept well below 2°C by 2100, the global economy must undergo rapid decarbonization.

The chapter provides a detailed review of greenhouse gas emission reduction potentials in 2030 for key economic sectors. Sectoral emission reduction potentials, also called...

Carbon dioxide removal (sometimes called carbon removal or CDR) refers to a cluster of technologies, practices and approaches that remove and sequester carbon dioxide from the...

This chapter outlines the opportunities to reduce the emissions gap afforded by limiting emissions of short-lived climate pollutants (SLCPs). This is a topic that has not been...

The assessment builds on all available information, including that reviewed by the IPCC in its fifth assessment report, as well as more recent scientific studies. The assessment...

This chapter provides an update, based on the latest available scientific literature, on trends in global emissions and progress towards the G20 members meeting their Cancun...

The eighth UN Environment Emissions Gap Report provides an up-to-date scientific assessment of the global progress towards the emissions reductions required to be on track to...

This Technical Annex to Chapter 3 of the 2016 UNEP Emissions Gap Report provides technical background to the computations supporting the discussion in the chapter. It reproduces...

This document includes: Appendix A Supplementary material for chapter 2: Global emissions trends; Appendix B Supplementary material for chapter 3: Nationally determined...

UNEP’s Emissions Gap Report 2021 finds that annual greenhouse gas emissions need to almost halve by 2030 to limit global warming to 1.5°C, but the updated Nationally Determined...

UNEP’s Emissions Gap Report 2021 finds that annual greenhouse gas emissions need to almost halve by 2030 to limit global warming to 1.5°C, but the updated Nationally Determined...

This chapter assesses the role of methane in the NDCs and in bridging the emissions gap, and considers options for cost-effective reductions of the otherwise growing emissions...

This chapter looks at how net-zero emission targets have emerged from the scientific understanding of the climate system and the goals of the Paris Agreement (section 3.2). It...

This chapter explores three questions: 1) How could COVID-19 related public spending bridge the emissions gap? 2) What are the characteristics of fiscal rescue and recovery...
