| Zusammenfassung |
| An understanding of the regional contributions and trends of anthropogenic
carbon dioxide (CO2) emissions is critical to design mitigation
strategies aimed at stabilizing atmospheric greenhouse gases. Here we report
CO2 emissions from the combustion of fossil fuels and land use change
in Africa for various time periods. Africa was responsible for an average of
500 Tg C y−1 for the period 2000–2005. These emissions resulted from the
combustion of fossil fuels (260 Tg C y−1) and land use change (240 Tg C
y−1). Over this period, the African share of global emissions from land
use change was 17%. For 2005, the last year reported in this study,
African fossil fuel emissions were 285 Tg C accounting for 3.7% of the
global emissions. The 2000–2005 growth rate in African fossil fuel emissions
was 3.2% y−1, very close to the global average. Fossil fuel
emissions per capita in Africa are among the lowest in the world, at 0.32 t C
y−1 compared to the global average of 1.2 t C y−1. The average
amount of carbon (C) emitted as CO2 to produce 1 US{$} of Gross
Domestic Product (GDP) in Africa was 187 g C/$ in 2005, close to the
world average of 199 g C/$. With the fastest population growth in the
world and rising per capita GDP, Africa is likely to increase its share of
global emissions over the coming decades although emissions from Africa will
remain low compared to other continents. |
