Evaluation of Sargassum cristaefolium, Sargassum crassifolium, and Enhalus acoroides as feed additives for improving rumen fermentation and mitigating enteric methane emissions in vitro [PDF]

Veterinary World
Background and Aim: Enteric methane emissions from ruminants contribute substantially to greenhouse gas accumulation and energy loss in livestock systems. In maritime regions such as Indonesia, macroalgae and seagrass represent abundant but underutilized

Under-reporting of greenhouse gas emissions in U.S. cities

Nature Communications, 2021
Many cities in the US self-report greenhouse gas emissions. Here, the authors find that US cities under-report their own greenhouse gas emissions, on average, by 18.3% because city inventories omit some fuels and source types and estimate transportation ...

Auctioning greenhouse gas emissions permits in Australia* [PDF]

Australian Journal of Agricultural and Resource Economics, 2010
The allocation of permits is an important design aspect of an emissions trading scheme. Traditionally, governments have favoured the free allocation of greenhouse gas permits based on individual historical emissions (‘grandfathering’) or industry benchmark data.

Greenhouse Gas Emissions From Cattle

Ekológia (Bratislava), 2015
Cattle produce greenhouse gases (GHG) which lead to changes in the chemical composition of the atmosphere. These gases which cause greenhouse effect include: methane (CH4), nitrous oxide (N2O), nitrogen oxides (NOx), sulphur dioxide (SO2), ammonia (NH3),

Conducting Life Cycle Assessments (LCAs) to Determine Carbon Payback: A Case Study of a Highly Energy-Efficient House in Rural Alaska

Energies, 2019
Buildings are responsible for a large portion of global greenhouse gas emissions. While energy efficiency features can significantly reduce the greenhouse gas emissions during a building’s operational stage, extra materials and processes associated

Population Under a Cap on Greenhouse Gas Emissions [PDF]

SSRN Electronic Journal, 2010
A cap on greenhouse gas emissions makes total emissions a fixed common-property resource. Population increases under a cap are therefore self-limiting: a population increase raises labor and reduces emissions per unit of labor, which lowers incomes and fertility.

Soil Inorganic Electron Acceptors and Carbon Substrates Hierarchically Govern Wetland Methanogenesis Temperature Response

Advanced Science, EarlyView.
ABSTRACT Wetlands constitute Earth's largest natural methane (CH4) source, yet projections of their climate feedback remain uncertain due to poorly constrained temperature sensitivity (Q10‐CH4) of microbial methanogenesis. While water table dynamics have been demonstrated to regulate wetland methanogenesis by altering key soil conditions such as ...

Tannin-Based Strategies for Mitigating Greenhouse Gas Emissions Through Nitrogen and Carbon Metabolism in Ruminants

Agriculture
Annual greenhouse gas emissions from livestock (CO2 equivalent) are estimated at approximately 7.1 billion tons, accounting for 14.5% of global emissions, with beef and dairy cattle production contributing 41% and 20% of total emissions, respectively ...

Modelling of Greenhouse Gas Emissions from Wheat Production in Irrigated and Rain-Fed Systemsin Khorasan Razavi Province, Iran [PDF]

International Journal of Agricultural Management and Development, 2017
Agriculture has a key role in greenhouse gas emissions. As such, the present study aimed to evaluate the greenhouse gas emissions from wheat production in irrigated and rain-fed systems. The primary data were collected from 116 wheat farmers.
