Regional and Global Emissions of Air Pollutants: Recent Trends and Future Scenarios

“…The recent UNEP/WMO's Integrated Assessment of Black Carbon and Tropospheric Ozone (7) concluded that emissions of NO x and SO 2 are generally well understood, whereas estimates of BC, OC, CO, and NMVOC emissions remain quite uncertain for many source types. This is consistent with the findings and recommendations of the UN Task Force in Hemispheric Transport of Air Pollution (2,28,71).…”

“…The extent to which this decoupling occurred varied among world regions, economic sectors, and pollutants as illustrated in Figure 1. The regional trends are calculated with the Greenhouse Gas Air Pollution Interactions and Synergies (GAINS) model ( 30) and are consistent with the energy statistics of the International Energy Agency (31), data used in the recent United Nations Environmental Programme/World Meteorological Organization assessment (7), and global (e.g., Reference 27) and regional trends (28,(32)(33)(34)(35)(36)(37) discussed in more detail below.…”

“…Only a very few papers analyze the global evolution of air pollutant emissions in the past decades (27)(28)(29), but a growing number of re-gional assessments has been published recently, especially for Asia, Europe, and the United States. These assessments clearly demonstrate that in many world regions the evolution of air pollutants has been effectively decoupled from economic growth.…”

Two hundred fifty years of aerosols and climate: the end of the age of aerosols

“…Global BC and OC emissions in the reference scenario are larger in 2030 and 2050 than any of the scenarios in Streets et al (2004); see ESM. The RCP4.5 emissions were also similar to several near-term scenarios for Asia in 2030 (Streets et al, 2010), although all of these newer scenarios were also higher than the estimates by Streets et al (2004).…”
