Item Restricted Assessing the Effectiveness of Carbon Trading Mechanisms in Promoting Carbon Reduction: A Case Study of the US(University of Glasgow, 2024-08-16) Alduraihem, Abdulaziz; Spagnolo, FabioThis study examined the effectiveness of the cap-and-trade policy adopted by California by exploring the effectiveness of the program in meeting the intended goals of reducing carbon emissions within the energy sector. The study used a deductive approach to analyse and empirically test the data using regression analysis. Data was sourced from government agencies in the fifty states and included per capita carbon emissions, carbon intensity, energy intensity, and GDP. The time frame for analysis was 2008 to 2021. The findings show that the cap-and-trade program implemented in California has resulted in a decrease in per capita CO2 emissions in the energy sector. The study also found that the effects of cap-and-trade did not intensify in the subsequent years after its adoption. Despite the limitations of data quality and availability, focus on per capita emissions and exclusion of carbon leakages, the findings of this study are crucial for economic policy development and implementation on carbon emissions.8 0Item Restricted Delivering a carbon net zero NHS at UCLH through more sustainable inhaler prescribing in the trust(University College London, 2024) Aldosari, Bodour; Roy, KayBackground Climate change, driven by anthropogenic greenhouse gas emissions, significantly impacts global health. The National Health Service (NHS) is committed to achieve net-zero carbon emissions by 2040, targeting reductions in healthcare-related emissions, including those from respiratory inhalers. Short acting beta agonist (SABA) are major contributors to the NHS’s carbon footprint due to their propellant gases. The North Central London has set key performance indicators to increase the use of lower-carbon inhalers. This project aims to primarily optimize asthma care within University College London Hospital (UCLH) by implementing sustainable inhaler prescribing practices in the emergency department (ED) and acute medical unit (AMU), aligning with these environmental goals. Methods Inhaler-sustainability champions delivered a regular education programme with interval performance of prescribing reported, following BTS-asthma 4 and surveys evaluating staff confidence pre- and post-training. Carbon footprint in NCL was calculated at community practice level and department level within UCLH to identify where more attention required. Teaching supported good disease management through prescribing of inhaled steroids and reduction in Salbutamol over-reliance with effective inhaler technique and adherence checks. We collected data pre and post interventions such as teaching to assess the impact of the educational interventions on clinical practice. Results There was an 18% and 40% reduction in SABA prescriptions in the ED and AMU respectively, cutting down carbon emissions by over 1,640 kg. Maintenance and reliever therapy prescriptions increased by 8.6% and 48% in ED and AMU, respectively. The Asthma 4 bundle application improved in the AMU. A staff surveys revealed overall improvement in knowledge and understanding after the educational intervention. Conclusion The implementation of sustainable inhaler prescribing practices in the ED and AMU at UCLH has led to a reduction in carbon emissions and improvements in clinical practice. Additionally, the educational interventions resulted in enhanced staff knowledge and understanding around optimal asthma care. These outcomes highlight the potential for such quality improvement initiatives in achieving both clinical excellence and environmental sustainability within healthcare settings8 0Item Restricted Role of Top Management in Carbon Risk: Evidence from Founder CEOs in the USA(Saudi Digital Library, 2023-08-27) Albalawi, Reem; Al Mamun, MuhammadFounder CEOs are important for the firm. They establish the firm and run the organization in the way that matches their vision and goal. They have a lot of decision-making power to take decisions that can influence firm’s outcome. Hence, this thesis examines the role of founder CEOs’ presence in US corporations on the carbon risk of the firm using firm level data on the release of carbon dioxide. The sample of the study is the period from 2002 to 2022. The findings of this study give us strong evidence the founder CEOs have negative and significant impact on reduction carbon emissions. The results are consistent when the study apply alternative econometric methods, address endogeneity problem using instrument variable approach, firm fixed effect and propensity score matching approach regression. The result also shows that founder CEOs effect on carbon risk is more significant and stronger for firms when founder CEOs have higher age. Moreover, the additional test show that the effect of founder CEOs on firm’s carbon risk is significant after adding new control variables such as CEO age, CEO tenure and CEO ownership. Overall, the findings of this research emphasize how important the founder CEO in respect to environmental sustainability.13 0
