The issue of low carbon emission reduction is getting more and more attention. This paper focuses on analyzing the equilibriums and digging deep into the impacts of cap-and-trade regulation, joint emission abatement scheme, and online direct channel on the performances of supply chain. By constructing two decentralized models in the single/joint emission abatement schemes under cap-and-trade regulation in a dual-channel supply chain, we find that consumer's environmental preference effectually motivates both the manufacturer and retailer to reduce emissions with joint emission abatement scheme. The analysis results show that introducing an online channel is always good for improving enterprises' profits, as well as protecting the environment in the joint emission abatement. Besides, the retailer should provide consumers with better service in the retail channel, which can further promote purchase power and drive the sustainable development of the supply chain. The manufacturer, when consumers have strong environmental preferences, should actively participate in cap-and-trade mechanism no matter single or joint emission abatement scheme is enforced.

Owing to critical policy significance, a growing body of literature has been predominantly concentrating on the social welfare benefits brought by green finance (GF) initiatives. However, there is a paucity of research that quantifies the economic costs of GF initiatives on carbon reduction, raising the increasing concerns about the irreconcilable climate-economy trade-offs. To end this, the present study systematically investigates the influence of GF initiatives on the carbon-related marginal abatement cost (MAC) using two competing hypotheses: regulatory versus technical effects.

Carbon dioxide (CO) accumulation and emission are well-known features of deep lakes, making them a significant unavoidable carbon source to the atmosphere. In the case of meromictic lakes, degassing devices are installed to controllably release through a pipe the CO trapped in the bottom waters. Otherwise, the gas is emitted diffusely at the air-water surface or accidentally through a limnic eruption when the saturation limit is reached.

Ammonia emissions from vehicles and power plants cause severe environmental issues, including haze pollution and nitrogen deposition. Selective catalytic oxidation (SCO) is a promising technology for ammonia abatement, but current catalysts often struggle with insufficient activity and poor nitrogen selectivity, leading to the formation of secondary pollutants. In this study, we developed a bifunctional Ru/Cu-CHA zeolite catalyst for ammonia oxidation, incorporating both SCO sites (Ru) and selective catalytic reduction sites (SCR, Cu).

The transition to net zero emissions requires the capture of carbon dioxide from industrial point sources, and direct air capture (DAC) from the atmosphere for geological storage. Dissolved CO has reactivity to rock core, and while the majority of previous studies have concentrated on reservoir rock or cap-rock reactivity, the underlying seal formation may also react with CO. Drill core from the underlying seal of a target CO storage site was reacted at in situ conditions with pure CO, and compared with an impure CO stream with SO, NO and O that could be expected from hard to abate industries.
