Background: Climate neutrality is the major aim of our generation. In order to be able to achieve this a net zero emission should be strived for in operating theaters.
Objective: What does zero emission implicate for the operative sector? Which structural approaches already exist? Can zero emission surgery be achieved?
Material And Methods: Evaluation of published studies, discussion of fundamental research and expert recommendations.
Results: Studies in England and Germany show that by structural alterations and strict sustainability structures net zero emission surgery seems to be feasible. In Germany the attention and awareness of the topic are greatly increasing and the first projects and studies have been launched.
Conclusion: To achieve the aim of net zero emission by 2050 we must rapidly and significantly increase our efforts.

Peatlands are invaluable but threatened ecosystems that store huge amounts of organic carbon globally and emit the greenhouse gasses carbon dioxide (CO) and methane (CH). Trophic interactions of microbial groups essential for methanogenesis are poorly understood in such systems, despite their importance. Thus, the present study aimed at unraveling trophic interactions between fermenters and methanogens in a nitrogen-limited, subarctic, pH-neutral fen.

While their preoperative diagnosis remains challenging due to the lack of specific diagnostic markers and imaging findings, there have been no detailed reports describing the diagnostic utility of various imaging modalities for bile duct NETs at the junction of the cystic and common hepatic ducts. We report a case of a woman in her 40s who presented with jaundice and elevated hepatobiliary enzymes.

In a hydrogen-based economy future, hydrogen leakage is becoming an environmental concern. Ruminants naturally produce small amounts of hydrogen, which is emitted in the environment along with other fermentation gases, such as the GHG methane and carbon dioxide. Here, for the first time, we estimated hydrogen emissions from the global ruminant livestock at 527 kt/yr (95% CI: 399, 654), or about 3.

The disposal of municipal solid waste (MSW) is a significant source of greenhouse gas (GHG) emissions. As incineration becomes the primary method of MSW disposal in China, MSW incineration (MSWI) plants are expected to play a crucial role in mitigating GHG emissions in the waste sector. This study estimated the quarterly GHG emissions from two representative MSWI plants in Qingdao using a life-cycle assessment (LCA) approach.

Taking a sewage treatment plant in Suzhou City, Jiangsu Province, as an example, the greenhouse gas (GHG) emissions generated in the sewage treatment system were calculated using the carbon balance method and the emission factor method. The environmental impacts and economic aspects of different treatment units in wastewater treatment plants were analyzed using life cycle assessment, cost-benefit analysis, and data envelopment analysis models, and emission reduction pathways were proposed. The results indicated that the total GHG emissions (in terms of CO) from a certain municipal wastewater treatment plant in Suzhou were 6 653.
