Battery Electric Vehicles: Travel Characteristics Of Early Adopters, Yunwen Feng, Jean-Daniel Saphores, Hilary Nixon, Monica Ramirez Ibarra
Mineta Transportation Institute
Do U.S. households with battery electric vehicles (BEVs) drive less or more than U.S. households with internal combustion engine vehicles (ICEVs)? Answering this question is important to policymakers and transportation planners concerned with reducing vehicle miles traveled and the emissions of greenhouse gases from transportation. So far, this question has not been answered satisfactorily, possibly because of the relatively low number of EVs in the U.S. until recently, but also because of methodological issues. In this paper, we aim to fill this gap by analyzing data from the 2017 National Household Travel Survey (NHTS). We apply propensity score matching (PSM), …

Are Corporations Responding To Civil Society Pressure?: A Multilevel Analysis Of Corporate Emissions, Annika Rieger
Research Collection School of Social Sciences
Previous research in the world-society tradition associates improvements in nation-level environmental outcomes with greater civil society integration. However, research in the world-systems tradition indicates these improvements depend on a nation’s position in the global political-economic hierarchy. To test whether these patterns are present at the organizational level, I estimate a multilevel model using corporate emissions data from the Carbon Disclosure Project and include interactions between world-system position and three measures of civil society integration: number of NGOs, proportion of corporations with climate-management incentives, and number of corporate UN Global Compact signatories. I find that the relationship between civil society pressure …

Sim Kee Boon Institute for Financial Economics
This paper investigates the applicability of the Just Transition Transaction (JTT), initially developed as a financial mechanism for South Africa's energy transition, to Southeast Asian (SEA) countries, including Indonesia, Vietnam, and the Philippines, which heavily rely on coal. Utilizing South Africa as a reference case study, we deconstruct the JTT and develop a novel framework of necessary and conducive features for evaluating its suitability for supporting a just energy transition in SEA. Our findings suggest that the JTT is well-suited for Indonesia and Vietnam but not as well suited for the Philippines. Recommendations for specific research avenues in estimating baselines …

Creating Synthetic Energy Meter Data Using Conditional Diffusion And Building Metadata, Chun Fu, Hussain Kazmi, Matias Quintana, Clayton Miller
Research Collection College of Integrative Studies
Advances in machine learning and increased computational power have driven progress in energy-related research. However, limited access to private energy data from buildings hinders traditional regression models relying on historical data. While generative models offer a solution, previous studies have primarily focused on short-term generation periods (e.g., daily profiles) and a limited number of meters. Thus, the study proposes a conditional diffusion model for generating high-quality synthetic energy data using relevant metadata. Using a dataset comprising 1,828 power meters from various buildings and countries, this model is compared with traditional methods like Conditional Generative Adversarial Networks (CGAN) and Conditional Variational …

Energy politics lie at the heart of human activity. In a time of ecological and energy crisis, it is fundamental to realise that our reality systems are always open to change and that, in order to respond to the challenges of a changing energy landscape, we must explore the full possibilities of technology in a radical way. This research aims to consider the ethical implications of energy and technology, presenting an urgent case for cosmotechnical pluralism, that is the diversification of world-views, knowledges, technologies in the pursuit of energy justice in global politics. To reconstruct the world and its politics …

Research Collection College of Integrative Studies
Missing data are frequently observed by practitioners and researchers in the building energy modeling community. In this regard, advanced data-driven solutions, such as Deep Learning methods, are typically required to reflect the non-linear behavior of these anomalies. As an ongoing research question related to Deep Learning, a model's applicability to limited data settings can be explored by introducing prior knowledge in the network. This same strategy can also lead to more interpretable predictions, hence facilitating the field application of the approach. For that purpose, the aim of this paper is to propose the use of Physics-informed Denoising Autoencoders (PI-DAE) for …

This essay explores the devastating impacts that global warming currently has on women living in the Sundarbans, the largest mangrove forest globally, located in South Asia. Womanist ideas are employed to identify the underlying injustices within environmental policies like the Paris Agreement, which undermine the effects of climate change in the global south. Initiatives led by women in vulnerable regions are then shared to offer ideas for improvement.
