Reporting scope and data verification
GRI reference: 2-2, 2-3, 2-4
This report covers the CLP Group’s sustainability performance for the calendar year ending 31 December 2021. It is published at the same time as the CLP Annual Report. The previous CLP Sustainability and Annual Reports were published in March 2021.
CLP reviews its reporting scope regularly to ensure the material impact of the Group’s overall portfolio is covered. In 2021, there were no major changes to the reporting scopes of its ESG metrics.
CLP has continued to enhance the disclosure of ESG metrics, and the highlights are as follows:
- Health, Safety and Environment (HSE): CLP has broadened the disclosure of safety and environmental metrics to meet external reporting requirements. New disclosures include: high-consequence injuries (representing life threatening or life-altering work-related injuries), mercury emissions and a number of water metrics. Several existing safety metrics have been revised to align with international reporting practices, and additional safety metrics are now independently assured.
- Asset management: CLP has started to report the sent out of each type of renewable energy, namely solar, hydro, wind and waste-to-energy. It complements the existing disclosure on the generation capacity of the individual components of the renewable energy portfolio. Individual data points are independently assured. The total capacity and total sent out of the portfolio are also provided in the report to enable performance assessment.
- Climate Vision 2050: CLP has converted the carbon emissions intensity (kg CO2/kWh) to GHG emissions intensity (kg CO2e/kWh) to align with the updated Climate Vision 2050 targets. Disclosure on the GHG emissions of the generation and energy storage portfolio is added to provide transparency to the calculation of the Group’s GHG intensity.
