Greenhouse gas (GHG) emission due to the fossil fuels combustion in the world's manufacturing industries with a share of 30% of emission is considered as one of the important potentials for GHG emission reduction. In this study, using the logarithmic mean of Division index (LMDI) method, in combination with Kaya model, the factors affecting the emissions of Iranian manufacturing industries, inc...

Total uncertainty in greenhouse gas (GHG) emissions changes over time due to “learning” and structural changes in GHG emissions. Understanding the uncertainty in GHG emissions over time is very important to better communicate uncertainty and to improve the setting of emission targets in the future. This is a diagnostic study divided into two parts. The first part analyses the historical change ...

The demand for fossil fuel in the transport sector is constantly increasing and transportation is ranked amongst the highest greenhouse emitting sectors globally. Today, tackling CO2 emissions from road transport a widely discussed topic and constitutes a milestone towards reaching a sustainable, carbon neutral economy. This challenge is being described in various initiatives adopted in the ...

Natural gas comprises almost one-fourth of all energy used in the U.S. New technologies, sometimes referred to as “unconventional” have enabled the production of more natural gas and have expanded domestic energy reserves. Natural gas is generally recognized as a clean-burning fuel source, producing less greenhouse gas (GHG) emissions per quantity of energy consumed than either coal or oil. How...

This study analyzes the climate change and economic impacts of food waste in the United States. Using lossadjusted national food availability data for 134 food commodities, it calculates the greenhouse gas emissions due to wasted food using life cycle assessment and the economic cost of the waste using retail prices. The analysis shows that avoidable food waste in the US exceeds 55 million metr...

On January 27, 2016, the Government of Canada announced that “direct and upstream greenhouse gas emissions” would factor into the regulatory review process for proposed pipeline projects.1 The new standard aims to address claims that new pipelines will induce greater expansion of Canada’s oil sands, producing more greenhouse gas (GHG) emissions. Specific details were not provided in the governm...

Methane is one of the most serious greenhouse gases contributing to irreversible climate change. The contribution of methane emissions from leaking pipelines and the expected increased throughput through the pipelines prompted the natural gas industry to set a goal of reducing emissions by 50% by 2010. The integrity of the pipelines is critical to the safety of the gas transportation infrastruc...

Since municipal solid waste (MSW) landfills emit significant amounts of methane, a potent greenhouse gas, there is considerable interest in quantifying surficial methane emissions from landfills. The authors propose a new and easier method by which to estimate methane emissions. The technique uses hundreds of ambient air VOC measurements taken within a landfill, as receptors, and solves the sta...

Climate change and agriculture influence each other. The effects of climate change on agriculture seem to be predominantly negative, although studies show a large variation in impacts between crops and regions. To compensate for these effects, agriculture can either intensify or expand in area; both of these options increase greenhouse gas emissions. It is therefore likely that such negative ef...

This paper is the second of a two part study which quantifies the economic and greenhouse performance of conventional, hybrid and fully electric passenger vehicles operating in Australian driving conditions. This second study focuses on the life cycle greenhouse gas emissions. Two vehicle sizes are considered, Class-B and Class-E, which bracket the large majority of passenger vehicles on Austra...
