Eggs are an increasingly significant source of protein for human consumption, and the global poultry industry is the single fastest-growing livestock sector. In the context of international concern for food security and feeding an increasingly affluent human population, the contribution to global greenhouse-gas (GHG) emissions from animal protein production is of critical interest. We calculate...

Looked at in a simplistic way, aerosols have counteracted the warming effects of greenhouse gases (GHG) over the past century. This has not only provided some 'climate protection', but also prevented the true magnitude of the problem from becoming evident. In particular, it may have resulted in an underestimation of the sensitivity of the climate system to the effect of GHG. Over the present ce...

China's freight transport volume experienced rapid growth over recent years, causing great concerns over its energy and environmental impacts. In this study, by establishing a bottom-up accounting framework, a set of scenarios reflecting the possible future trajectories of energy consumption and Greenhouse Gas (GHG) emissions from China's freight transport sector are developed. According to our...

Biochar (BC) application to agricultural soils could potentially sequester recalcitrant C, increase N retention, increase water holding capacity, and decrease greenhouse gas (GHG) emissions. Biochar addition to soils can alter soil N cycling and in some cases decrease extractable mineral N (NO and NH) and NO emissions. These benefits are not uniformly observed across varying soil types, N ferti...

greenhouse gas (gHg) emissions from agriculture, including crop and livestock production, forestry and associated land use changes, are responsible for a significant fraction of anthropogenic emissions. using data from a new gHg global database developed at FAO, we focus on global indicator trends in the agriculture sectors, in relation to the carbon intensity of key food commodities. in partic...

This paper presents a baseline projection until 2020 of the future energy supply and demand situation in Greece, the associated trajectories of greenhouse gas (GHG) emissions, and the effects of an environmental tax equivalent to $40/t of carbon dioxide (CO2). The latter scenario represents a rough estimation of the GHG emissions abatement potential in the country’s various energy sectors. The ...

The livestock sector contributes considerably to global greenhouse gas emissions (GHG). Here, for the year 2007 we examined GHG emissions in the EU27 livestock sector and estimated GHG emissions from production and consumption of livestock products; including imports, exports and wastage. We also reviewed available mitigation options and estimated their potential. The focus of this review is on...

Companies around the world are increasingly expected to report their greenhouse gas emissions. Currently there are various formulas to calculate emissions, and there are different reporting formats. Most of the reporting formats are paper-based or non-readable-by-machine formats. The emissions of companies will influence their accounting results due to ‘cap & trade’ systems or environmental tax...

Bioenergy is increasingly being used to meet EU objectives for renewable energy generation and reducing greenhouse gas (GHG) emissions. Problems with using biomass however include high moisture contents, lower calorific value and poor grindability when compared to fossil fuels. Torrefaction is a pre-treatment process that aims to address these issues. In this paper four torrefaction treatments ...

We present results of a life cycle assessment (LCA) of Marcellus shale gas used for power generation. The analysis employs the most extensive data set of any LCA of shale gas to date, encompassing data from actual gas production and power generation operations. Results indicate that a typical Marcellus gas life cycle yields 466 kg CO2eq/MWh (80% confidence interval: 450-567 kg CO2eq/MWh) of gre...
