adaptação às alterações climáticas

adaptation to climate change

The process of preparing to cope with living in a changing climate, e.g. increased rainfall , higher temperatures, scarce water, or more frequent storms.


fuga de carbono

carbon leakage

The part of emission reductions in Annex B countries (countries that have their greenhouse gas emissions capped under the Kyoto Protocol) offset by an increase in emissions in non-constrained countries above their baseline levels.


mercado do carbono

carbon market

Trading system through which countries may buy or sell units of greenhouse gas emissions in an effort to meet their national limits on emissions, either under the Kyoto Protocol or under other agreements, such as that among Member States of the European Union.


crédito de compensação de carbono

carbon offset

A unit of carbon dioxide equivalent that is reduced, avoided, or sequestered to compensate for emissions occurring elsewhere.


unidade de redução certificada de emissões

certified emission reduction unit (CER)

Unit generated from a Clean Development Mechanism project activity, certifying an emission reduction of one tonne of carbon dioxide equivalent.


Mecanismo de Desenvolvimento Limpo

Clean Development Mechanism (CDM)

Defined in Article 12 of the Kyoto Protocol, a mechanism allowing a country with an emission reduction or emission limitation commitment under the Kyoto Protocol (Annex B Party) to implement an emission reduction project in developing countries.


alterações climáticas

climate change

A change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.


mitigação das alterações climáticas

climate change mitigation

Action to reduce the net amount of greenhouse gases released into the atmosphere, and thus help to slow down the process of climate change resulting from human activities.


período de compromisso - período de cumprimento

commitment period

Five-year period in which the Parties to the Kyoto Protocol undertake to reduce greenhouse gas emissions.


licença de emissão

emission allowance

Within the context of the EU Emissions Trading Scheme (EU ETS), the entitlement to emit a tonne of carbon dioxide or an amount of any other greenhouse gas with an equivalent global warming potential during a specified period.


unidade de redução de emissões

emission reduction unit (ERU)

Unit generated from a Joint Implementation activity, certifying an emission reduction of one tonne of carbon dioxide equivalent.


redução das emissões

emissions reduction - emissions abatement

Reduction in emissions (e.g. of greenhouse gases).


comércio de emissões - comércio de licenças de emissão

emissions trading

A market-based approach to achieving environmental objectives that allows those reducing e.g. greenhouse gas emissions below what is required to use or trade the excess reductions to offset emissions at another source inside or outside the country.


Regime de Comércio de Emissões da UE - Regime de Comércio de Licenças de Emissão da UE

EU Emissions Trading Scheme (EU ETS)

Company-level 'cap-and-trade' system of allowances for emitting carbon dioxide and other greenhouse gases, launched by the EU at the beginning of 2005.


Fundo Verde para o Clima

Green Climate Fund

Operating entity provided for under the Copenhagen Accord to support projects, programmes, policies and other activities in developing countries related to mitigation.


gás com efeito de estufa

greenhouse gas (GHG)

A gas, such as water vapour, carbon dioxide, methane, chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), that absorbs and re-emits infrared radiation, warming the Earth’s surface and contributing to climate change.


Painel Intergovernamental sobre as Alterações Climáticas

Intergovernmental Panel on Climate Change (IPCC)

A scientific intergovernmental body established to provide decision-makers and others interested in climate change with an objective source of information about climate change.


Implementação Conjunta

Joint Implementation (JI)

Mechanism defined in Article 6 of the Kyoto Protocol, which allows a country with an emission reduction or limitation commitment under the Kyoto Protocol (Annex B Party) to earn emission reduction units from an emission reduction or emission removal project in another Annex B Party, each equivalent to one tonne of carbon dioxide, which can be counted towards meeting its Kyoto target.


Protocolo de Quioto à Convenção-Quadro das Nações Unidas sobre Alterações Climáticas

Kyoto Protocol to the United Nations - Framework Convention on Climate Change - Kyoto Protocol

An international agreement, linked to the United Nations Framework Convention on Climate Change, which commits industrialised countries to reducing greenhouse gas emissions.


tecnologia hipocarbónica - tecnologia de baixo carbono

low-carbon technology

Technology which results in reduced emissions of carbon dioxide compared with conventional technology.


sumidouro

sink

Any process, activity or mechanism which removes a greenhouse gas, an aerosol or a precursor of a greenhouse gas from the atmosphere.
