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.

Structural Engineering Expert Available to Discuss High-Rise Building Stability, Structural Failures and Building Safety

University of Delaware structural engineering expert Michael Chajes is available to discuss the engineering challenges involved in assessing and stabilizing high-rise buildings following structural damage, structural failures and concerns about potential collapse. Chajes, a professor of civil and environmental engineering and a registered professional engineer, specializes in structural engineering, structural health monitoring and forensic engineering. He has provided expert commentary to national media outlets on major structural failures, including the Surfside condominium collapse and the Francis Scott Key Bridge collapse. His expertise is particularly relevant to the ongoing situation in New York involving a high-rise that is at-risk of partial collapse. He can discuss. • The conditions that can trigger structural instability during construction, renovation or changes in building use. • How engineers assess damaged structures and determine whether a building can be stabilized or safely repaired. • The engineering challenges involved in converting older office towers into residential buildings, including changes in structural loads, construction sequencing and temporary support systems. • How structural health monitoring and inspection technologies help engineers evaluate the safety of aging infrastructure and high-rise buildings.

Post-earthquake crisis in Venezuela: University of Delaware experts available to discuss public health, infrastructure and relief

Faculty from the University of Delaware’s renowned Disaster Research Center are available to comment on the back-to-back earthquakes in Venezuela. These experts can discuss critical infrastructure failures, public health threats, emergency logistics and community-led response efforts in the region. Available experts include: From what I’ve seen, it looks like the earthquake occurred on the boundary of the Caribbean and South American plate. A strike-slip fault similar to the San Andreas. There have been a lot of nonductile reinforced concrete frame building collapses. There may be an effect of soil given that a lot of the damage has been near the coast. Jennifer Horney (Professor of Epidemiology) Focus: Public health impacts, post-disaster waterborne/vector-borne disease outbreaks and the breakdown of healthcare delivery due to damaged roads and disrupted communication networks. Tricia Wachtendorf (Co-director, Disaster Research Center) Focus: Disaster response logistics, community improvisation, neighbors as first responders and how to donate effectively to maximize impact. Sarah DeYoung (Associate Professor, Sociology and Criminal Justice) Focus: Maternal and infant health/feeding in emergencies, pet and companion animal evacuations and community-level crisis decision-making.

From clay on the ground to construction on the moon

Building material samples from the University of Delaware spent six months mounted outside of the International Space Station, where the harsh conditions of low Earth orbit tested their limits. Some returned with higher measured strength than identical samples stored on Earth. The findings are a promising sign for the long-term goal of building infrastructure on the moon. There are no lunar supply yards, and transporting building materials from Earth would be prohibitively expensive. The solution may lie underfoot, in the form of lunar dust known as regolith. “Regolith is essentially a clay-like silicate material,” said Norman Wagner, Unidel Robert L. Pigford Chair in Chemical Engineering. “It is one of the most abundant materials on both Earth and the moon, which makes it interesting for construction.” Wagner's laboratory develops geopolymers, a cement alternative that binds clays into a strong solid through chemical reactions rather than high-temperature manufacturing. Their goal is to use regolith with minimal additives to produce construction materials without energy-intensive processing. The approach could contribute to more sustainable Earth-based construction, too. To evaluate how geopolymers hold up in space, the UD team sent thin plates made from commercially available simulated lunar and Martian regolith to the International Space Station as part of NASA's MISSE-20 mission. The findings, published in Advances in Space Research, showed the geopolymers did not deteriorate, and in some cases were stronger after their time in orbit. Lunar construction materials must not only survive space conditions, they also must be reliably manufactured on-site. In a separate study in Acta Astronautica, Wagner's team used artificial intelligence to tackle a practical challenge: not all lunar clays are the same. The researchers developed a machine learning model that can predict how strong a geopolymer will be based on the characteristics of the starting regolith and how it is processed. Complementary work from the Wagner lab offers insight into how geopolymers behave while being mixed, pumped and shaped before they harden. The researchers identified a key transition point, known as the critical gel point, at which the material shifts from a workable slurry into a solidifying structure. Mixing or shearing before that point did not affect how long the material took to harden or its final strength. This suggests that engineers may have flexibility in how they handle and process lunar construction materials, without compromising quality. That work appears in a special issue of the Journal of Rheology focused on materials behavior beyond Earth. To speak with Wagner about his space expertise, reach out to mediarelations@udel.edu.
