Rice-related greenhouse gases in Japan, variations in scale and time and significance for the Kyoto Protocol
The contribution of rice production to the three major greenhouse gases CO2, CH4 and N2O in 1990, the base year of the Kyoto protocol is investigated for Japan. For the CO2 assessment, we use a top-down life cycle approach, CH4 is assessed using the Japanese GHG emission inventory and N2O is assessed according to the ratio of rice area divided by the total area of agricultural soils. In total, ...

The role of driving in reducing greenhouse gas emissions and oil consumption
Transportation represented 71 percent of oil consumption and 31 percent of carbon dioxide (CO2) emissions in the United States in 2008. Therefore, federal transportation policy presents an opportunity to reduce both oil consumption and greenhouse gas (GHG) emissions. This report explores whether technology improvements alone can achieve oil consumption and GHG emissions reduction targets ...

Dietary choices and greenhouse gas emissions – assessment of impact of vegetarian and organic options at national scale
This study quantifies the sources of agricultural GHG emissions and explores the impact of diet on GHG emissions in Finland. The emissions associated with production of basic food items were quantified for four diet options. For current average food consumption, emissions from soil represent 62% of the total. The emissions due to enteric fermentation contribute 24%, and energy consumption and ...

Harmonising equity and efficiency in allocating global post-Kyoto GHG emissions
In this paper, a non-parametric efficiency analysis approach is presented for determining Greenhouse Gases (GHG) tradable emissions allowances for all countries. The approach has two steps: expansion and contraction. In the expansion step and given its population, each country is projected on the efficient frontier and a maximum GDP and associated energy and GHG emissions levels are computed. ...

Legal lookout: EPA issues final “tailoring” GHG permitting rule
EPA estimates that Title V permits would be required for over six million sources not now subject to the program. On June 3, 2010, EPA issued a final rule addressing greenhouse gas (GHG) emissions from stationary sources under the Clean Air Act (CAA). This controversial rule set thresholds for GHG emissions that define when permits under the New Source Review Prevention of Significant ...

Wastewater treatment process impact on energy savings and greenhouse gas emissions
The objective of this research was to assess the energy consumption of wastewater treatment plants (WWTPs), to apply a mathematical model to evaluate their carbon footprint, and to propose energy saving strategies that can be implemented to reduce both energy consumption and greenhouse gas (GHG) emissions in Greece. The survey was focused on 10 WWTPs in Greece with a treatment capacity ranging ...

The reduction of greenhouse gas emissions using various thermal systems in a landfill site
In this paper, the Greenhouse Gas (GHG) emissions from an uncontrolled landfill site filled with Municipal Solid Waste (MSW) are compared with those from controlled sites in which collected Landfill Gases (LFG) are utilised by various technologies. These technologies include flaring, conventional electricity generation technologies such as Internal Combustion Engine (ICE) and Gas Turbine (GT) and ...

GHG Protocol Initiative - A step forward in GHG emissions calculations
With the GHG Protocol 60 companies will look comprehensively at the impact of their corporate value chains, reports Envido. On January 20th, the GHG Protocol Initiative announced that 60 companies had started measuring the greenhouse gas emissions of their products and supply chains by testing a new global framework, part of the Greenhouse Gas Protocol Initiative. Developed by the World Resources ...

Greenhouse Gas Verification Programme
Greenhouse Gas verification programme in the aluminum industry 1. BUSINESS CHALLENGE Over the past decade, the aluminum companies operating in Quebec have voluntarily achieved significant reductions in their greenhouse gas (GHG) emissions. In 2002, the Aluminum Association of Canada and the Government of Quebec signed a covenant to voluntarily reduce an additional 200,000 tons of GHG ...

Greenhouse gas emissions of fossil fuel-fired power plants: current status and reduction potentials, case study of Iran and Canada
In this paper, methodology to estimate GHG emissions from electricity generation sector using Iran as an example was first explained. Then different scenarios to reduce GHG emissions were evaluated for two countries: Canada and Iran. The results demonstrated that there were great potentials for GHG emission reduction in both countries. These potentials were evaluated by introducing eight ...

Greenhouse gas emissions in Europe: a retrospective trend analysis for the period 1990-2008
This report presents a retrospective overview of the greenhouse gas (GHG) emission trends in Europe from 1990 to 2008, with a particular focus on the underpinning drivers and the influence of EU policies. The analysis is based on the combination of decomposition analyses to identify the respective influence of each identified driver and an overview of the main EU policies and their likely effects ...

Bottom line on regulating greenhouse gases under the clean air act
How can the EPA regulate GHGs? Doesn’t the Clean Air Act only apply to air pollutants? An April 2007 Supreme Court decision (Massachusetts v. EPA) ruled that GHGs are air pollutants under the Clean Air Act. The court instructed the EPA to decide whether GHG emissions endanger public health and/or welfare, or if current science is too uncertain to make a reasonable judgment. In response to the ...

Reports On Canadian Biofuels GHG Emissions Argue For And Against Biofuel Mandates Over Carbon Pricing
On October 4, 2016, Canada’s Ecofiscal Commission (EFC) published a report, Course Correction: It’s Time to Rethink Canadian Biofuel Policies, arguing for the termination of biofuel subsidies. The report claims that Canadian biofuel policies have reduced greenhouse gas (GHG) emissions an average of three million tonnes annually, accounting for less than 0.5 percent of Canada’s ...

A new approach to climate change: ideas beyond carbon emissions
Climate change is considered one of the greatest challenges in the relationship between humans and nature. One general belief is that this latest process of climate change is being accelerated (or even caused) by human greenhouse gases (GHG) emissions. Based on that, almost all suggested actions to cope with the problem are about reducing GHG emissions. Therefore, on this essay, the purpose is to ...

Environmental and economic assessment of municipal sewage sludge management – a case study in Beijing, China
A case study was conducted in Beijing to identify municipal sewage sludge (SS) management systems appropriate for a sound material-cycle society. The environmental and economic impacts of four realistic SS-handling scenarios were investigated: stabilization by thermal drying, increased inclusion of SS in cement manufacture, and using either dried or carbonized SS as substitute fuel for ...

More Changes Ahead for the Greenhouse Gas Reporting Rule
More Changes Ahead for the Greenhouse Gas Reporting Rule U.S. EPA continues to work on the Mandatory Greenhouse Gas (GHG) Reporting Rule (MRR) that was codified at 40 CFR Part 98 on October 30, 2009 (74 FR 56260). So far this work has included proposed new source categories and proposed amendments to the general provisions of the original MRR that will impact sources that are required to report ...

Analysing the levels of human-induced greenhouse gas emissions from land use, land use change and forestry activities on Annex I countries ability to meet Kyoto targets
This study analyses the 1990 and current Greenhouse Gas (GHG) emissions data from Annex I countries and assesses the impacts of LULUCF (Land Use, Land Use Change and Forestry) activities of countries in meeting their Kyoto targets. In a 'business-as-usual' scenario for the period 1990-2010, the total GHG emissions, excluding LULUCF activities of Annex I Parties, would decrease by 3.7%, whilst a ...
