The main anthropogenic source of CO2 emissions is the combustion of carbon-based fuels. Since 1860, industrialization has progressed with an increase in the use of fuels - especially fossil fuels - and a corresponding increase in CO2 emissions. The growth has been steady and exponential, interrupted only by the two World Wars and the Great Crash of 1929. In 1997 the emissions reached a maximum of 6.6 PgC yr-1 (0.2 PgC yr-1 of this was from cement production). The average value of emissions increased from 5.44 ± 0.3 PgC yr- in 1980s to 6.3 ± 0.4 PgC yr-1 in 1990s.
