Reporting GHG Emissions: Change in Uncertainty and Its Relevance for Detection of Emission Changes

by Khrystyna Hamal

- This study analyzes the relative uncertainty in emissions of greenhouse gases over time that countries report in their annual national inventories under the Kyoto Protocol to the United Nations Framework Convention on Climate Change. The analysis shows how to take advantage of emissions estimates that are recalculated annually and how this knowledge can be used to estimate biases (systematic errors) that are included in the reporting (first-order approximation or one-sided view). This study focuses on the EU-15 as a whole, with examples drawn from individual countries.
