Three of the main challenges in achieving rapid decarbonization of the electric power sector in the near term are getting to net-zero while maintaining grid reliability and minimizing cost. In this policy analysis, we evaluate the performance of a variety of generation strategies using this "triple objective" including nuclear, renewables with different energy storage options, and carbon-emitting generation with carbon capture and storage (CCS) and direct air capture and storage (DACS) technologies. Given the current U.S. tax credits for carbon sequestration under Section 45Q of the Internal Revenue Code, we find that two options: (1) cofiring bioenergy in existing coal-fired assets equipped with CCS, and (2) coupling existing natural gas combined-cycle plants equipped with CCS and DACS, robustly dominate other generation strategies across many assumptions and uncertainties. As a result, capacity-expansion modelers, planners, and policymakers should consider such combinations of carbon-constrained fossil-fuel and negative emissions technologies, together with modifications of the current national incentives, when designing the pathways to a carbon-free economy.

There has been a rapid rise in utilization of artificial intelligence (AI) in many different sectors in the last several years. However, business-to-business (B2B) marketing is one of the more notable examples. The initial assessments emphasize the significant advantages of AI in B2B marketing, including its knack for yielding unique understandings into consumer behaviors, recognizing crucial market trends, and improving operational efficiency.

Article Synopsis
- The digital economy is emerging as a key driver for high-quality economic development and is crucial in achieving carbon neutrality through technological advancements.
- A general equilibrium model demonstrates that the digital economy effectively reduces carbon emission intensity, supported by empirical tests that confirm its reliability.
- Regional variations are observed in the digital economy's impact on carbon emissions, with central and western regions benefiting more significantly post-"Broadband China" strategy implementation compared to the eastern region.
CO Sequestration Technologies May Undermine China's Sustainable Development Goals through the Climate-Energy-Air-Health Cascade.

CO sequestration technologies (CSTs) allow for increased CO emissions without exceeding a chosen temperature limit by creating additional carbon budgets. While these CO sequestration technologies offer low-cost routes to net-zero emissions, namely, the CST benefits, they impede progress to the Sustainable Development Goals, namely, the CST disbenefits. Focusing on China, we assess both the CST disbenefits and benefits in the climate-energy-air-health cascade by an integrated modeling framework.

The resilience of established business strategies has been tested in the wake of recent global supply chain upheavals triggered by events like the COVID-19 pandemic, Russia-Ukraine combat, Hamas-Israel war, and other geopolitical conflicts. Organizations are compelled to integrate sustainable practices into their supply chains to navigate the complexities of the post-COVID-19 era and mitigate the far-reaching consequences of such disruptions. However, exploring supply chain imperatives from sustainability dimensions still remains underexplored, presenting a significant research gap, particularly in the fashion retail sector.

In the last decade, there has been a push for greater evidence-based practice within the humanitarian sector, alongside an increasing turn towards localising humanitarian assistance. Humanitarian actors and organisations have been increasing their production and use of evidence, while also being encouraged to reflect more critically on power hierarchies and decolonise humanitarian aid. This paper explores the intersection of these two narratives, examining how the use of evidence in humanitarian decision-making fits within a localisation agenda.
