Environmental targets and data management
In 2022, CLP developed a new set of group-wide annual environmental targets covering air emissions, waste and water management for its fossil fuel plants, which account for the majority of CLP’s emissions and resource consumption. To drive continuous improvements and meet external stakeholder expectations, CLP’s group-wide environmental targets are tracked and reviewed on an annual basis. Details of the targets are discussed in the respective environmental sections.
Digital technology in data management is deployed to ensure data integrity and measure progress against targets, as well as facilitate the follow-up actions for each asset for continual improvement. In addition to CLP’s customised Group Operations Information System (GOIS), CLP has been implementing MonitorPro, an environmental data management system across all its operational assets in Australia. The tool is designed to safeguard environmental data, automate trend analysis and data reporting and support compliance and risk management.

CLP closely monitors developments in environmental regulatory requirements. In Hong Kong, the emission allowances of CLP's power plants have been progressively tightened over time through the Technical Memorandums (TM) of the Air Quality Control Ordinance. Since 2022, a new set of emission caps requires CLP Power Hong Kong Limited (CPL Power) to further reduce the emissions of sulphur dioxide (SO2), nitrogen oxides (NOx) and Respiratory Suspended Particulates (RSP) by 12% to 27% compared with the 2021 level which CLP Power has achieved. Discussion with the Hong Kong Government on the review of the latest TM is in progress, as the new 2028 emissions caps will be promulgated in 2023.
In India, the Ministry of Environment, Forest and Climate Change issued the E-Waste (Management) Rules, 2022, which will be effective from April 2023. These rules require the bulk consumers of electrical and electronic equipment, including solar PV panels/cells, to ensure their e-waste will be handed over only to the registered producer, refurbishing entity or recycler. A gap assessment is under progress to ensure compliance of all applicable statutory requirements by March 2023.
Emerging policy changes in relation to GHG emissions are discussed in the Climate-related Disclosures Report.

In Australia, there were six environmental licence breaches recorded in 2022.
Three of them were relevant to marginal air emissions exceedances. One related to particulate matter emissions at Mount Piper Power Station, and two others related to particulate matters and SO2 emissions at Yallourn Power Station.
Another two breaches were from Mount Piper Power Station during a 21-day emergency discharge event. One related to the exceedance of the daily limit of discharge volume, while another one related to missing oil and grease test in the weekly water samples.
The local Environment Protection Authority (EPA) was notified of these five incidents. Associated corrective and preventive active actions have been taken by EnergyAustralia to prevent recurrence of similar incidents. None of them resulted in any actions by EPA.
The other licence limit exceedance case related to oil spillage from Jeeralang Power Station due to the failure of one of its unit transformers. The oil contamination was cleaned up by using vacuum tankers and removing the contaminated soil. EnergyAustralia notified EPA and is currently liaising with them for a case review.
In India, there were eight cases of short-term SO2 licence limit exceedances at Jhajjar Power Station in 2022. In all these incidents, Jhajjar Power Station had requested a loading reduction or shutdown of the unit to control SO2 emissions. However, the State Load Dispatch Centre of India denied permission to reduce the loading or shutdown of the unit due to the state’s high power demand. Subsequently, Jhajjar Power Station continued to run the unit and recorded exceedences. All these exceedances were reported to the regulatory authorities (the Central Pollution Control Board (CPCB) and Haryana State Pollution Control Board (HSPCB)) which have not imposed any penalties or taken any further action.
