A carbon credit is a tradeable instrument which represents either (a) a permit which gives the holder the right to emit one tonne of carbon dioxide or equivalent greenhouse gas (tCO2e) into the atmosphere or (b) a certificate from a project that represents the removal or avoidance of one tCO2e from the atmosphere. CLP Carbon Credits ( are generated from renewable energy sources and can be used to offset carbon emissions generated by governments, organisations or individuals.

Carbon neutral

When the greenhouse gas emissions associated with an activity or entity are balanced by carbon removal elsewhere, such as carbon credits, renewable energy certificates, carbon sinks or storage. Also known as net zero carbon dioxide emissions.

Clean energy

Generally refers to power sources that add no extra carbon to the atmosphere. Non-carbon emitting energy, including renewable energy, is considered clean energy in CLP’s context.

Climate Action Finance Framework (CAFF)

Launched in 2017, CAFF supports the transition to a low-carbon economy by attracting socially responsible, sustainable financings, and to support CLP’s investments that reduce the carbon content of energy generated and increase the efficiency of energy usage.

Climate Vision 2050

CLP’s Climate Vision 2050 sets out a series of 10-year targets from 2010 to 2050 compared to 2007 levels. These targets are based on the company’s generation capacity on an equity plus long-term capacity and energy purchase basis. They consist of decarbonisation targets, measured in terms of the Group’s carbon intensity, and clean energy targets, based on the renewable and non-carbon emitting energy share of CLP’s generation portfolio.

Combined-cycle gas turbine (CCGT)

A technology used in gas-fired generation to enable significantly higher efficiency by utilising residual heat from gas turbine exhaust to run steam turbine and generating additional electricity.

Generation capacity

The maximum amount of power that a generator is rated to produce. Also known as installed capacity or nameplate capacity.

Greenhouse gas (GHG)

The emission of gases that contribute to the greenhouse effect causing a changing climate. CLP’s GHG emissions inventory covers the six GHGs specified in the Kyoto Protocol. Nitrogen trifluoride (NF3), the seventh mandatory gas added under the second Kyoto Protocol was deemed immaterial to CLP’s operations after an evaluation.

The GHG Protocol Corporate Standard classifies an organisation’s GHG emissions into three ‘Scopes’. Scope 1 emissions are direct emissions from owned or controlled sources. Scope 2 emissions are indirect emissions from the generation of purchased energy. Scope 3 are indirect emissions (not included in Scope 2) that occur in the value chain of the organisation.

Incremental distribution network (IDN)

To open up the distribution market in an orderly manner as part of the ongoing reforms of the electricity market in Mainland China, the Government is encouraging power companies to set up IDNs to provide safe and reliable electricity services using a newly-added distribution network and to meet demand from users in designated areas such as business and industrial parks.

Intergovernmental Panel on Climate Change (IPCC)
