World Greenhouse Gas Emissions in 2005

This research paper provides an updated view of global anthropogenic greenhouse gas (GHG) emissions for 2005, specifically focusing on the revised contribution of land-use change to total emissions based on updated data and methodologies.

• The share of global greenhouse gas emissions attributed to land-use change was revised downward to 12.2% for 2005, compared to an 18.2% estimate in a 2000 chart. This decrease is attributed to revised methodologies in the Forest Resources Assessment (FRA) data rather than a reduction in actual deforestation rates.
• While the percentage share of emissions from land-use change decreased, the total CO2 emissions from this sector actually increased between 2000 and 2005; the share dropped because emissions in other sectors grew at faster rates.
• Estimates for CO2 from land-use change remain subject to significant uncertainty. IPCC 4th Assessment Report studies indicated global error ranges of up to ±2,933 MtCO2 (±0.8 GtC) during the 1990s. A November 2009 statement by forest experts suggested a best estimate of approximately 15% if peat degradation is included.
