This chapter assesses the latest trends in greenhouse gas (GHG) emissions and the progress of G20 members towards both the Cancun Pledges for 2020 and nationally determined contributions (NDCs) for 2025 and 2030. Throughout the chapter, the implications of the COVID-19 pandemic on emissions in 2020 and by 2030 are considered.
The chapter is organized as follows: section 2.2 takes stock of the current trends in total global GHG and carbon dioxide (CO2) emissions from fossil fuel use and industry-related sources. These trends are discussed in the context of global peaking of emissions and general economic trends. Sections 2.3 and 2.4 assess G20 members’ progress, both collectively and individually, towards their Cancun Pledges and NDCs.1 The assessment covers all individual G20 members and regions, including the European Union and its three individual Member States (France, Germany and Italy), as well as the United Kingdom (hereafter EU27+UK) as one member.2 Section 2.5 provides an update of announced net zero emissions goals and the implications for short- to medium-term action in the context of new and updated NDCs.
