Summary: This study calculates and analyzes the greenhouse gas emissions of one of the largest gas refining companies in the Middle East for the first time, finding that CO2 and CH4 emissions mainly come from direct sources and fugitive emissions are minimal. The study suggests the need for further research in different regions to gain a more comprehensive understanding of the adverse effects of gas emissions on human populations.

Summary: The income and expenditure elasticity of household carbon footprints are important indicators of the social stratification of greenhouse gas emissions. They are used to estimate the inequality in emissions between households across the income or expenditure distribution. This article discusses methodological considerations when computing the elasticity of household carbon footprints and demonstrates their practical and empirical implications using Belgian survey data. The choice between income and expenditure as the main variable has the most significant impact on estimated household carbon footprints, while the income elasticity of household emissions is affected by a broader range of methodological choices. This has implications for estimating emissions along the income distribution and measuring inequality in household emissions by income groups.

Summary: Straw incorporation is widely used to improve crop productivity, and biochar amendment may be an effective countermeasure for reducing greenhouse gas emissions. However, there is insufficient data on the comprehensive evaluation of straw return and biochar amendment coupled with different N application rates on soil organic carbon sequestration rate, GHG emissions, and reactive N losses.

Summary: Stable isotopes play a crucial role in identifying contamination sources and tracking gas emissions in various fields of geosciences, aiding in evaluating environmental impacts and reducing emissions. The study conducted in volcanic and urban zones of the Mediterranean region demonstrated the effectiveness of stable isotopes in understanding CO2 sources and their fate. The detailed investigations using isotopic compositions contributed to broader research perspectives and enhanced understanding of the carbon cycle.

Summary: Constructed wetlands (CWs) are widely used for non-point source pollution control and water environmental quality improvement. However, their overall impacts on greenhouse gases (GHGs) emissions are a growing concern. The study found that CWs have good water quality improvement performance, especially for nitrogen removal. They also act as a carbon sink, sequestering a substantial amount of CO2, but they also emit significant amounts of CO2, CH4, and N2O.

Summary: Healthcare systems contribute 4%-5% of global greenhouse gas emissions. The environmental impact of health services is mainly due to indirect emissions (scope 3), with disposables, equipment, and pharmaceuticals accounting for a higher percentage. It is important for healthcare organizations to take action to reduce carbon emissions and for individuals to make changes.

Summary: The building sector is a major contributor to pollutant gas emissions, which have detrimental effects on the health impacts of climate change. This comparative study evaluates two buildings with similar characteristics but different structures (metal and concrete) using Building Information Modeling (BIM) for design, structural calculation, and three-dimensional dimensioning. The study also includes budget and product carbon footprint analysis to quantify emissions from each building. The results show higher emissions from the metal-structured building compared to the concrete building. To reduce these emissions, measures such as material substitution with lower emission rates were proposed, resulting in significant reductions in CO2 emissions. This study provides valuable insights for selecting sustainable materials in building renovations or new construction projects, particularly in the current COVID-19 pandemic situation where health-related buildings are in high demand.

Summary: The C-14 levels in methane and carbon dioxide were observed in an urban area (London) using a newly developed sampling system. The observed values surpassed the simulated values, indicating higher fossil fuel proportions and atmospheric concentrations. The correlation between observed and simulated net biospheric uptake was poor in June-July.

Summary: Over 1.3 billion tonnes of food are wasted globally each year, leading to significant greenhouse gas emissions. The Food Bank of Navarra plays a crucial role in reducing this waste and associated emissions. Without the actions of the food bank, a much higher amount of CO2 would have been released. The findings highlight the importance of integrating food banks into climate change policies.

Summary: The magnitude of stream and river carbon dioxide emission is influenced by seasonal changes and global estimates are uncertain. River CO2 emission varies significantly between regions, with hydrology playing a crucial role in the carbon transfer from land to the atmosphere.

Summary: Finland aims to achieve carbon neutrality by 2035, while the EU aims for 2050. This study evaluated Finland's potential to reach carbon neutrality at the national and regional scale, considering EU biodiversity targets. Modeling was done for anthropogenic emissions, forestry measures, and spatial prioritization of forest areas important for biodiversity protection. The results show the complementarity of emission mitigation and conservation measures, with significant carbon storage and sequestration potential by 2050.

Summary: In response to the need for greenhouse gas emission reduction, organizations are increasingly accounting for their carbon footprint. However, existing guidelines often do not consider the unique characteristics of organizations such as higher education institutions. This study provides a case study for a Northern European institution, aiming to expand the available calculation methodologies and identify limitations and mitigation measures for reaching carbon neutrality.
