=== 2.3.2 Trends in Global and Regional CBEs Trajectories ===

<div id="h2-6-siblings" class="h2-siblings"></div>

In comparison to territorial emissions discussed in [[#2.2|Section 2.2]] , Figure 2.14 shows the trends of global and regional CBEs from 1990 to 2018. This section uses the PBEs and CBEs data from the Global Carbon Budget 2020 ( [[#Friedlingstein--2020|Friedlingstein et al. 2020]] ), which are slightly different from the PBEs used in [[#2.2|Section 2.2]] . The Global Carbon Budget only includes CO 2 emissions from fossil fuels and cement production.

'''Figure 2.14''' '''|''' '''Consumption-based CO''' 2 '''emissions trends for the period 1990–2018.''' The CBEs of countries are collected from the Global Carbon Budget 2020 ( [[#Friedlingstein--2020|Friedlingstein et al. 2020]] ). Source: this figure is modified based on [[#Hubacek--2021|Hubacek et al. (2021)]] .

The two panels at left in Figure 2.14 show total and per capita CBEs for six regions. The three panels on the right show additional information for the 18 top-emitting countries with the highest CBEs in 2018. In Developed Countries, consumption-based CO 2 emissions peaked at 15 GtCO 2 in 2007 with a subsequent 16% decline until 2016 (to 12.7 GtCO 2 ) and a slight rebound of 1.6% until 2018 (to 12.9 GtCO 2 ). Asia and Pacific has been a major contributor to consumption-based CO 2 emissions growth since 2000 and exceeded Developed Countries as the global largest emissions source in 2015. From 1990 to 2018, the average growth rate of Asia and Pacific was 4.8% per year, while in other regions emissions declined by –1.1%–4.3% per year on average. In 2018, 35% of global consumption-based CO 2 emissions were from Developed Countries and 39% from Asia and Pacific, 5% from Latin American and Caribbean, 5% from Eastern Europe and West Central Asia, 5% from Middle East, and 3% from Africa ( [[#Hubacek--2021|Hubacek et al. 2021]] ). Global CBEs kept growing over the period with a short-lived decline in 2008 due to the global financial crisis. In 2020, lockdowns associated with COVID-19 significantly reduced global emissions ( [[#2.2.2|Section 2.2.2]] ), including CBEs ( [[#Shan--2021a|Shan et al. 2021a]] ).
