Net-zero emissions targets: Genuine goals or Fortune 500 greenwashing?

Moving towards “net-zero” emissions has become a popular “target” for multinational corporations that have committed to improving their sustainability. But is it a new tagline from marketing departments or something firms are actually committed to?


About half of the U.S.-based Fortune 500 firms have declared their intent to reach net zero – the point at which the emissions from an entity equals the amount of greenhouse gasses being taken out of the atmosphere – as early as by 2030.


The University of Delaware’s Kalim Shah, an expert on energy and climate policy, has some thoughts on these targets, their feasibility and why these companies are pursuing these goals.


  • We should question why the language has changed in less than a decade from lowering emissions or low carbon options to “net-zero” when targets to meet lower emissions have not really been fulfilled in the first place. Part of the explanation could be to get ahead of would-be legislated pressure, that is, to dissuade legislative efforts which would imply compliance requirements, whereas now, these pledges are completely voluntary.
  • Net zero is more technologically feasible in some sectors/ processes and not in others. In other words, there is likely not a cost effective, technological fix for net zero in the aluminum smelting or iron or concrete making industries in the immediate future.
  • Lack of industry standards for measuring net zero – or perhaps more correctly, several competing methods of calculating net zero – can give some cover, for now, to firms attempting to “greenwash.” In effect, one firm's net zero may not be comparable to another's net zero.
  • A company’s “emissions scope” must be examined closed. Are firms referring to direct emissions related to on-site fuel combustion or fleet vehicles; Indirect emissions related to emission generation of purchased energy, such as heat and electricity; and/or Other indirect emissions related to both emissions from upstream and downstream business activities when setting targets?
  • We have to "read the fine print" as well, as terms that sound as ambitious but have slightly different strategies, such as “carbon neutral” and “carbon negative” targets can also complicate how we hold firms accountable.
  • Where net zero is less possible, emissions could be “offset” through various schemes like carbon credits of forest offsets. A carbon offset is a reduction or removal of emissions of greenhouse gases made in order to compensate for emissions made elsewhere. En vogue since the 2000s, largely because it presented a way for indebted developed countries to capture market value by preserving endangered forests when multinationals ‘"offset" operations emissions by paying said developing countries, this mechanism has become highly questionable of late for its unverifiability.

Inside the Italian art heist: Experts explain the global fight to protect cultural heritage

A lightning-fast art heist in Italy has reignited global concerns about museum security and the protection of cultural heritage. As investigators search for stolen works by some of history’s most celebrated artists, University of Delaware experts are available to help journalists unpack the broader implications. Earlier this month, thieves executed a highly coordinated robbery at the Magnani-Rocca Foundation, stealing paintings by Pierre-Auguste Renoir, Paul Cézanne and Henri Matisse in a matter of minutes. Authorities say the operation was swift, targeted and likely premeditated – highlighting the evolving sophistication of art crime. The theft adds to a growing pattern of high-value art crimes across Europe, raising urgent questions about how institutions safeguard collections and what happens when culturally significant works disappear into illicit markets. UD experts are available to provide context, analysis and on-the-record commentary: Debra Hess Norris Chair, Department of Art Conservation A globally recognized leader in art conservation, Norris specializes in the protection, preservation and recovery of cultural heritage. She can speak to: How museums assess and mitigate security risks What happens after a major art theft The challenges of recovering stolen works in international markets How conservation science supports authentication and repatriation Jessica Horton Associate Professor of Art History Horton’s research examines global art histories and the movement of cultural objects across borders. She can discuss: Why stolen artworks matter beyond their monetary value Cultural ownership, repatriation and ethical considerations How art theft disrupts historical narratives and public access The broader cultural consequences of illicit art trafficking While headlines focus on the dramatic nature of art heists, the deeper story is about the fragility of cultural heritage – and the global effort required to protect it.

Delaware emerges as a test bed for the future of AI in health care

Delaware is positioning itself as a “living lab” where academia, health systems and government collaborate to shape the future of artificial-intelligence-enabled health care.  The latest issue of the Delaware Journal of Public Health, guest edited by University of Delaware computer scientists Weisong Shi and Yixiang Deng, brings together 16 articles from researchers, clinicians, policymakers and industry leaders examining how AI and big data are reshaping health care. The issue, debuting this month, balances Delaware-specific topics with broader perspectives, highlighting three levels of impact: what Delaware can expect in the coming years, what other states can learn from Delaware’s approach and how UD research is advancing AI for health through collaborations. “At UD, we don’t work in isolation. We’re working closely with health care systems so that innovation happens together from the beginning,” says Shi, Alumni Distinguished Professor and Chair of UD’s Department of Computer and Information Sciences. Highlights from the issue include: The nation’s first nursing fellowship in robotics – ChristianaCare, Delaware’s largest health system, created an eight-month fellowship to train bedside nurses to conduct applied robotics research. Nurses who completed the program reported higher job satisfaction, improved well-being and greater professional confidence, suggesting programs like this may help retain the bedside workforce and reduce nationwide staffing shortages. Wheelchairs that navigate hospitals on their own – UD researchers developed a prototype autonomous wheelchair that combines onboard sensors and computing with software that interprets spoken directions from users, a step toward moving beyond systems that only work in controlled environments. To operate effectively in health care settings, the researchers say, wheelchairs must be able to navigate crowded hallways, interact with doors and elevators and recover safely when sensors or navigation systems fail. Smarter insulin dosing for type 1 diabetes – Researchers are developing computer models to predict blood sugar (glucose) trends and guide insulin delivery, but must address issues such as noisy data, reliable real-time prediction and the computational limits of wearable devices. A review by UD researchers and colleagues emphasizes the importance of interdisciplinary collaboration, standardized datasets, advances in computational infrastructure and clinical validation to turn these models into practical tools that improve patient care.
