Ambiguity in factors such as data reliability, access to emissions databases, and emissions calculation methods have resulted in inconsistent, disorganized Scope 3 measurement and management on a global scale. While the Greenhouse Gas Protocol (GHG Protocol) has released its ‘Scope 3 Calculation Guidance’ to guide companies on disclosure-related matters, this document is merely suggestive. Companies can openly interpret this piece of guidance, which often results in uncertainty around what data companies use in their Scope 3 measurements and how they use this data. Recognizing the financial implications of Scope 3 data, financial institutions have started to consider Scope 3 emissions in their evaluations of lending and credit decisions. This project aims to build a consensus on the global and Hong Kong jurisdictional status of Scope 3 disclosure policies and the existing research in this field through a literature review. The project will then evaluate the current practices of firms in select sectors in Hong Kong, specifically addressing how firms calculate their Scope 3 emissions and identify potential sources of error and uncertainty in these calculations. Study on the Ozone Episodes in Hong Kong Supervisor: WANG Zhe / ENVR Student: LEE Jason Chung Hei / CHEM-IRE Course: UROP 1100, Summer Surface ozone pollution has adverse effects on human health and the environment. It causes respiratory disease and eye irritation in the public. Ozone pollution is also related to vegetation destruction. Despite the Hong Kong government’s efforts to reduce the emission of precursors in recent years, including volatile organic compounds (VOCs) and nitrogen oxides, the local ozone level is still increasing. Here, the general trend of ozone from 2011-2023 and the 2019 September to November ozone episode are studied. The focus of this report is to find out the reasons behind the increasing general ozone trend and ozone episodes that happen from time to time.
