Emissions from airport sources degrade air quality impacting community health. While some airports assess air pollution, others assess broader environmental effects, including CO emissions and noise. Utilising a transition management approach, this paper examines Australian airport practices and develops key sustainable strategies to reduce environmental impacts. After reviewing environmental policies and reports from eight major airports and conducting in-depth interviews with 18 sustainable aviation experts, five key strategies are proposed: 1) Collaborating data-sharing among stakeholders, including airport operators, ground handlers, airlines and air traffic controllers; 2) Evaluating emissions from aircraft ground idling delays; 3) Advancing in the Airport Carbon Accreditation program; 4) Assessing air pollutant emissions directly emitted from airport sources; 5) Maintaining an air pollutant emissions inventory. Airports should integrate these strategies into their environmental policies to support their long-term sustainable goal of reaching net zero emissions by 2050.

The escalating global fecal waste and rising CO levels present dual significant environmental challenges, further intensified by urbanization. Traditional fecal waste management methods are insufficient, particularly in addressing the related health risks and environmental threats. This study explores the synthesis of biochar from pig manure as a carbon substrate to disperse and stabilize Cu nanoparticles, resulting in the formation of an efficient Cu-NB-2000 electrocatalyst for electrocatalytic CO reduction (ECR).

Accelerated global urban expansion not only directly occupies surrounding ecosystems, but also induces cascading losses of natural vegetation elsewhere through cropland displacement. Yet, how such effects alter the net primary productivity (NPP) worldwide remains unclear. Here, we quantified the direct and cascading impacts of global urban expansion on terrestrial NPP from 1992 to 2020 and projected the impacts under the shared socioeconomic pathways framework by 2100.

Botulinum toxin, through its inhibitory effects, has been hypothesized to improve premature ejaculation (PE). This study evaluates high-quality evidence on botulinum toxin-A injections into the bulbospongiosal muscle as a treatment for PE.

Indonesia currently calculates CO emissions from gas fuels using Tier 1 emission factors adopted from the Intergovernmental Panel on Climate Change (IPCC). However, this method may not accurately capture the country's specific emission characteristics. To address this, this study aims to derive country-specific CO emission factors for gas fuels, including liquefied petroleum gas (LPG), liquefied gas for vehicles (LGV), natural gas (NG), and liquefied natural gas (LNG), by analyzing fuel samples collected nationwide.

In 2022, the European Union put forward the REPowerEU plan in response to Russia's invasion of Ukraine, aiming at enhancing short-term energy security by diversifying imports and reducing natural gas demand while accelerating the deployment of renewable alternatives in the long term. Here, we quantify the life cycle environmental impacts of both REPowerEU's short-term measures, including the controversial extended coal-fired power plant operations, and how the first year of the crisis was managed in practice. We find that the policy measures' impact on greenhouse gas (GHG) emissions would be negligible, although they could have detrimental effects on other environmental categories.
