In a Policy Forum, David Victor and colleagues outline a framework for incentivizing meaningful investments into high-risk, transformative clean technologies in the aviation industry. While massive reductions in global emissions are needed to combat climate change, most current clean investments focus on low-risk, mature technologies such as renewable energy, batteries, and electric vehicles. However, many sectors, including aviation, which accounts for about 3% of global emissions, face steep technological and economic barriers to decarbonization, making formative solutions risky and unattractive to investors. These industries are also highly competitive, leaving little room for bold, costly experimentation. According to Victor et al., building a low-carbon aviation industry requires tackling two core issues: the lack of breakthrough clean technologies and weak incentives for investors to take risks on them. In a competitive, capital-intensive sector, the authors note that few will innovate without stronger support and rewards for risk-taking. Although vast sums of money flow into aviation each year, almost none is directed toward sustainability, as investors favor low-risk, high-return projects. To address this, the authors propose an “aviation sustainability index” (ASI), which assigns measurable scores to projects, like adopting efficient aircraft or sustainable fuels, based on their emissions impact. This could help guide investment decisions by providing a credible framework linking financial rewards to verified climate benefits. This could allow investors to distinguish genuine progress from greenwashing and steer capital toward high-impact projects. “In many respects, the challenges in this sector are shared across other “hard to abate” sectors such as ship- ping, heavy freight, steel, and others,” write Victor et al. “All face the common challenge that there are many ideas for new technologies and business models, but none gets sufficient traction because investors don’t know which vision is most credible; there are few rewards for taking bigger risks.”

Cutting planet-warming pollution to near-zero will take more than inventing new clean technologies—it will require changing how the world invests in them. That’s especially true for industries like aviation, where developing and adopting greener solutions is risky and expensive, according to a University of California San Diego commentary piece in Science. 

In a new study, researchers analyzed power outage data and corresponding weather records from several major service territories on the east coast of the United States. They found that excessive weather stress and planning vulnerabilities at specific grid nodes are key drivers of prolonged local outages, which spread to the whole system. The authors use their findings to suggest ways to reduce customer outages.

MedAxiom, the premier source for cardiovascular organizational performance solutions, has released its 2025 Cardiovascular Provider Compensation and Production Survey report that includes data from the largest number of programs since its debut. With 232 cardiovascular programs submitting 2024 data, MedAxiom’s 13th annual survey saw a 15% increase in program participation and a 21% increase in cardiovascular providers represented. The survey is powered by MedAxcess, the cardiovascular industry’s leading business intelligence application and proprietary database. 

Consumers are more likely to choose a higher-priced item when it’s correlated with messages that emphasize an increase in the product’s positive attributes—rather than a reduction in its negative ones.

New study on a ‘portfolio approach’ to carbon removal enables firms to mix expensive tech-based solutions that inject carbon deep underground with lower-cost and currently more available nature-based options.
