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.
When the greenhouse gas emissions associated with an activity or entity are balanced by carbon removal elsewhere, such as carbon credits, carbon sinks or storage, and renewable energy certificates.
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. The CAFF formalises and governs project evaluation, management of proceeds and reporting for Climate Action Finance Transactions, including bonds, loans and other forms of finance.
Climate Vision 2050
CLP’s Climate Vision 2050 sets out the blueprint of the Group’s transition to net-zero greenhouse gas emissions leading up to mid-century. Launched in 2007 with a focus on the ambition to mitigate CLP’s climate impact, Climate Vision 2050 has been instrumental in informing CLP’s business strategy and guiding its investment decision-making.
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.
Decarbonisation of the power sector primarily refers to the reduction in the greenhouse gas emissions from electricity generation, and providing lower-carbon energy services and solutions to customers. At CLP it is measured by the reduction in carbon intensity, which is expressed in kilograms of carbon dioxide per kilowatt hour of electricity sent-out.
Decentralised generation / distributed generation
Refers to electrical generation and storage performed by a variety of technologies of a smaller scale located close to the load they serve. In contrast, centralised generation is the large-scale generation of electricity serving multi-loads connected to the transmission network.
Demand response programmes encourage participating customers to commit to short-term reductions in electricity demand, helping energy suppliers to keep the grid running optimally during high load periods.
The application of new information technologies including artificial intelligence and data analytics to help electric utilities develop new customer-centric services and improve operations.
Distributed energy includes power generated from sources such as solar panels and wind turbines located close to the users, as well as controllable loads or storage such as electric vehicles and batteries.
Gross electricity generated by a power plant less self-generated auxiliary power consumption, measured at the connecting point between generating unit and transmission line.
Evolution in the business strategy of energy companies to provide a more diverse range of value-adding energy services and solutions such as consultancy, energy management and distributed energy resources to customers, in addition to basic utility services.

The uninterrupted availability of energy sources.
Transformation of the global energy sector from fossil-fuel based energy systems to low- or zero-carbon sources.
Energy transition enablers
Non-generation products or services that facilitate the energy transition, including energy storage, transmission and distribution, electric vehicle charging points and smart meters, amongst others.
An approach set out by the GHG Protocol Corporate Standard for an organisation to consolidate GHG emissions for the purpose of accounting and reporting GHG emissions. On this basis, the organisation accounts for GHG emissions from operations according to its equity share in the operations.
Feed-in Tariff (FiT)
Payable by Hong Kong power companies under the SoC agreement to purchase electricity from approved renewable energy projects. Find out more at https://www.clp.com.hk/en/business/low-carbon-solutions/renewable-energy/feed-in-tariff-business
Flue gas desulphurisation (FGD) facility
Equipment used to remove sulphur oxides from the combustion gases of a boiler plant before discharge to the atmosphere.
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.
Large, transformative global forces that define the future by having a far-reaching impact on business, economies, industries, societies and individuals. A megatrend is distinguished from other trends in that it cannot be stopped or significantly altered, even by powerful actors such as governments.
Megatrend analysis is an important tool for companies aiming to drive sustainable growth as competition increases and new disruptive ideas and concepts affect entire industries.
Localised networks with generation, energy storage and load entities, that can operate in tandem with an existing grid or independently. They can potentially be deployed to meet the energy needs of remote areas cost-effectively, foregoing the expenses of transmission grids.
National Electricity Market (NEM)
Australia’s NEM is a wholesale spot market connecting six regional market jurisdictions – Queensland, New South Wales, the Australian Capital Territory, Victoria, South Australia, and Tasmania.
Net-zero greenhouse gas emissions
When greenhouse gas emissions are reduced, and the residual emissions is balanced by the removal of an equivalent amount of greenhouse gases from the atmosphere.
Non-carbon energy/non-carbon emitting energy
Energy from power sources that add no extra carbon to the atmosphere, such as wind, solar, hydro and nuclear energy. It does not include waste-from-energy and other forms of biomass.
Operational control basis
An approach set out by the GHG Protocol Corporate Standard for an organisation to consolidate GHG emissions for the purpose of accounting and reporting GHG emissions. On this basis, the organisation accounts for 100 percent of the GHG emissions from operations over which it has operational control, but does not account for GHG emissions from operations in which it owns an interest but has no control.
