Emissions from Amazon deforestation in Brazil fall 57% since 2004
Annual emissions from deforestation in the Brazilian Amazon fell by about 57 percent between 2004 and 2011, 20 percentage points lower than the recorded drop in deforestation, reports a new study published in the journal Global Change Biology by Brazilian scientists. Overall, Brazilian deforestation represented roughly 1.5 percent of global carbon emissions from human activities. The results are based on a new emissions tracking system developed by researchers at Brazil's National Institute for Space Research (INPE) and other institutions. The system uses satellite data and biomass maps to estimate carbon emissions on an annual basis. According to Nature , the 20 percent difference between the drop in annual forest clearing and emissions can be partly attributed to "a natural lag as carbon stocks slowly decay and make their way into the atmosphere as carbon dioxide."
