Climate Analysis Indicators Database from the World Resources Institute (WRI)

The Climate Analysis Indicators Tool (CAIT) is an information and
analysis tool on global climate change. It provides a comprehensive
and comparable database of greenhouse gas emissions data (including
all major sources and sinks) and other climate-relevant
indicators. CAIT can be used to analyze a wide range of
climate-related data questions and to help support future policy
decisions made under the Climate Convention and in other fora.

Indicators in CAIT are divided into three categories: GHG Emissions,
Socio-Economic, and Natural Factor indicators. GHG Emission Indicators
include annual emissions of greenhouse gases as well as indicators
that relate to the historical responsibility for climate
change. Socio-Economic Indicators are framed broadly and include
numerous indicators that relate to the capabilities that countries may
have to protect the climate system, including health, education,
income, governance and other indicators. Finally, Natural Factor
Indicators represent those factors that tend to lie largely beyond the
reach of public policy (like climatic conditions, fossil fuel
reserves, and geography), but which nevertheless may significantly
influence greenhouse gas emissions.

CAIT includes emissions of (1) CO2 from fossil fuels and cement
(1850-2000), (2) CO2 from land-use changes (1950-2000), (3) and
non-CO2 gases, such as methane (CH4) and nitrous oxide (N2O) (1990,
1995, 2000).

CAIT includes two main groups of countries: (1) Parties to the UNFCCC
and (2) non-Parties that are members of the United Nations. All UNFCCC
Parties are included in CAIT except Liechtenstein, Marshall Islands,
Micronesia, Monaco (combined with France), San Marino (combined with
Italy), and Tuvalu. In these cases, there was inadequate emissions
data. The European Union is also included as a "country" because the
European Community (a subset of the EU) is a Party to the
Convention. Non-Parties included in CAIT are limited to the following
UN member states: Afghanistan, Brunei, Iraq, Liberia, and Turkey. The
only exception to the two criteria above is the inclusion of Taiwan
(Chinese Taipei), which is neither a UN member nor a Convention
Party. This exception is made because Taiwan (Chinese Taipei) is a
significant source of emissions.
