Integrating Pollutant registers for the climate change risk evaluation of industrial companies in Australia, Europe and North America

Introduction Albeit climate-related financial disclosure is becoming a norm with more governments in developed countries adopting the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD), not all companies are preparing strategies, selecting key performance indicators and setting targets to contribute to reaching the global objective of minimizing global warming to 1.5C by 2050. Firms TCFD/climate risk disclosures are prone to become a ceremonial practice with ’cheap talk’, ’greenwashing’ or ’cherry-picking’ and reporting of primarily non-material climate risk information 1 , 2 . Pollutant Release and Transfer Registers (PRTRs) and Greenhouse Gas Reporting Programs (GHGRPs) are increasingly used as fundamental data sources for corporate climate and environmental footprint research 3 , 4 , 5 , 6 . National pollution registers offer a nuanced examination of local pollution 7 , but neglect to offer international assessment. Earlier studies on PRTRs focused on the chemical footprint assessment of point-source emissions and calculated impact potentials for human toxicity and ecotoxicity as key metrics to measure chemical footprints on the national, pollutant and facility level 3 , 8 , 9 . The Japanese PRTR was used for an input-output analysis and decomposition analysis, to measure the socio-economic factors of changes in toxicological footprint 10 . Earlier carbon footprint methods helped assess resource consumption, (CO_2) emission and related climate change risk separately, but usually neglected integrated assessment of other indicators 11 . The improvement of various physical and transition risk assessment methods has become an urgent task for the scientific research community, however, there is still an obvious gap between the contribution of the scientific research community and enterprise needs 12 . Investors and regulators require as well reliable estimates of physical climate risks for decision-making 13 . The methodology developed by the present study gives corporate-level insight on the potential corporate strategies […]
