Alliances of countries, in most cases sharing the same geographic region, which meet privately to discuss issues
and nominate bureau members and other officials for activities under the Convention. The five regional groups are
Africa, Asia, Central and Eastern Europe (CEE), Latin America and the Caribbean (GRULAC), and the Western Europe
and Others Group (WEOG).
Registries, registry systems
Electronic databases that tracks and records all transactions under the Kyoto Protocol's greenhouse-gas
emissions trading system (the "carbon market") and under mechanisms such as the Clean Development
Mechanism. "Registry" may also refer to current discussions on a system for inscribing nationally
appropriate mitigation actions.
Research and systematic observation
An obligation of Parties to the Climate Change Convention; they are called upon to promote and cooperate in
research and systematic observation of the climate system, and called upon to aid developing countries to do
An exception or concern noted for the record by a Party in the course of accepting a decision of the COP or the
CMP. No reservations are allowed to the Convention itself, or to the Protocol.
A component or components of the climate system where a greenhouse gas or a precursor of a greenhouse gas is
stored. Trees are "reservoirs" for carbon dioxide.
Directives that guide the work of the COP or the CMP-- opinions rather than permanent legal acts. Unlike decisions,
resolutions do not generally become part of the formal body of legislation enacted by the COP or the CMP.
Review of commitments
Regular scrutiny by Convention Parties of the adequacy of the treaty's Article 4.2 (a) and (b) outlining
developed country commitments to limit greenhouse-gas emissions. The first review took place at COP-1 and led to a
finding that progress was not "adequate" -- and so to negotiations that led to the Kyoto Protocol, which
has more stringent commitments for developed countries.
Three environmental conventions, two of which were adopted at the 1992 "Earth Summit" in Rio de Janeiro:
the United Nations Framework Convention on Climate Change (UNFCCC), and the Convention on Biodiversity (CBD), while
the third, the United Nations Convention to Combat Desertification (UNCCD), was adopted in 1994. The issues
addressed by the three treaties are related -- in particular, climate change can have adverse effects on
desertification and biodiversity -- and through a Joint Liaison Group, the secretariats of the three conventions
take steps to coordinate activities to achieve common progress.
The United Nations Conference on Sustainable Development, to be held in Rio de Janeiro, Brazil, on June 4-6, 2012.
The first UN Conference on Sustainable Development was the "Earth Summit", held in 1992, and it spawned
the three "Rio Conventions"-- the UNFCCC, the UNCCD, and the UNCBD.
Removal unit (RMU)
A Kyoto Protocol unit equal to 1 metric tonne of carbon dioxide equivalent. RMUs are generated in Annex I Parties
by LULUCF activities that absorb carbon dioxide.
Roster of experts
Experts nominated by Parties to the Climate Change Convention to aid the Secretariat in work related to review of
national reports of Annex I Parties, preparation of reports on adaptation technology, the transfer of technology to
developing countries, and the development of know-how on mitigating and adapting to climate change.
Rules of procedure
The parliamentary rules that govern the procedures of the COP, the CMP and the subsidiary bodies, covering such
matters as decision-making and participation. The COP has not yet formally adopted rules of procedure, but all
except one (on voting) are currently being "applied." As such, they are commonly referred to as the
"draft rules of procedure being applied".
Second Assessment Report (SAR)
An extensive review of worldwide research on climate change compiled by the IPCC and published in 1995. Some 2,000
scientists and experts participated. The report is also known as Climate Change 1995. The SAR concluded that
"the balance of evidence suggests that there is a discernible human influence on global climate." It also
said "no-regrets options" and other cost-effective strategies exist for combating climate change.
The office staffed by international civil servants responsible for "servicing" the UNFCCC Convention and
ensuring its smooth operation. The secretariat makes arrangements for meetings, compiles and prepares reports, and
coordinates with other relevant international bodies. The Climate Change Secretariat, which is based in Bonn,
Germany, is institutionally linked to the United Nations.
Small island developing States.
The signing by a head of state or government, a foreign minister, or other designated official indicating a
country's agreement with an adopted international text, such as a Convention or Protocol, and signalling the
country's intention of becoming a Party to the agreement.
Any process, activity or mechanism which removes a greenhouse gas, an aerosol or a precursor of a greenhouse gas
from the atmosphere. Forests and other vegetation are considered sinks because they remove carbon dioxide through
Special Climate Change Fund (SCCF)
The SCCF was established to finance projects relating to adaptation; technology transfer and capacity building;
energy, transport, industry, agriculture, forestry and waste management; and economic diversification. This fund
should complement other funding mechanisms for the implementation of the Convention. The Global Environment
Facility (GEF), as the entity that operates the financial mechanism of the Convention, has been entrusted to
operate this fund. For more information click here.
"Spill-over effects" (also referred to as "rebound effects" or "take-back
Reverberations in developing countries caused by actions taken by developed countries to cut greenhouse-gas
emissions. For example, emissions reductions in developed countries could lower demand for oil and thus
international oil prices, leading to more use of oil and greater emissions in developing nations, partially
off-setting the original cuts. Current estimates are that full-scale implementation of the Kyoto Protocol may cause
5 to 20 per cent of emissions reductions in industrialized countries to "leak" into developing
A committee that assists the Conference of the Parties. Two permanent subsidiary bodies are created by the
Convention: the Subsidiary Body for Implementation (SBI) and the Subsidiary Body for Scientific and Technological
Advice (SBSTA). Two major temporary bodies that exist currently are the Ad Hoc Working Group on Further Commitments
for Annex I Parties under the Kyoto Protocol (AWG-KP), established at COP 11 in Montreal, and the Ad Hoc Working
Group on Long-term Cooperative Action under the Convention (AWG-LCA), established at COP 13 in Bali. Additional
subsidiary bodies may be established as needed.

Subsidiary Body for Implementation (SBI)
The SBI makes recommendations on policy and implementation issues to the COP and, if requested, to other
Subsidiary Body for Scientific and Technological Advice (SBSTA)
The SBSTA serves as a link between information and assessments provided by expert sources (such as the IPCC) and
the COP, which focuses on setting policy.
Development that meets the needs of the present without compromising the ability of future generations to meet
their own needs.
A broad set of processes covering the flows of know-how, experience and equipment for mitigating and adapting to
climate change among different stakeholders
Third Assessment Report (TAR)
The third extensive review of global scientific research on climate change, published by the IPCC in 2001. Among
other things, the report stated that "The Earth's climate system has demonstrably changed on both global
and regional scales since the pre-industrial era, with some of these changes attributable to human activities.
There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to
human activities." The TAR also focused on the regional effects of climate change.
One of two approaches for verifying emission reductions or removals under joint implementation, whereby each JI
project is subject to verification procedures established under the supervision of the Joint Implementation
Supervisory Committee. Track two procedures require that each project is reviewed by an accredited independent

A draft article considered during the negotiation of the Kyoto Protocol that would have permitted developing
countries to voluntarily adhere to legally binding emissions targets. The proposed language was dropped in the
final phase of the negotiations. The issue remains important for some delegations and continues to be discussed,
currently in the context of the Bali Action Plan, in terms of what constitutes "voluntary".
The degree to which a system is susceptible to, or unable to cope with, adverse effects of climate change,
including climate variability and extremes. Vulnerability is a function of the character, magnitude, and rate of
climate variation to which a system is exposed, its sensitivity, and its adaptive capacity.
