This database contains data from both intervention and non-intervention
scenarios of future emissions of greenhouse gases, supporting the activities
of the IPCC Special Report on Emission Scenario (SRES). The goal of the SRES
was to provide a basis for analysis of potential future climatic changes and
associated impacts as well as a reference for socio-economic analysis of
long-term mitigation options. Several of the scenarios are the results of an
integrated assessment (IA) model - they take into consideration the
interactions between energy, economy, and land use changes.

Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2000. Central to
any study of climate change is the development of an emissions inventory
that identifies and quantifies a country's primary anthropogenic sources and
sinks of greenhouse gases. This current inventory adheres to both (1) a
comprehensive and detailed methodology for estimating sources and sinks of
anthropogenic greenhouse gases, and (2) a common and consistent mechanism
that enables signatory countries to the United Nations Framework Convention
on Climate Change (UNFCCC) to compare the relative contribution of different
emission sources and greenhouse gases to climate change. Moreover,
systematically and consistently estimating national and international
emissions is a prerequisite for accounting for reductions and evaluating
mitigation strategies.
