Description

Extraction and upgrading/refining of mined bitumen are energy intensive operations that require significant fuel consumption resulting in emissions of greenhouse gases. The less understood part of GHG emissions from surface mining operations is methane and carbon dioxide production from fluid tailings ponds. Part I of this paper explains past, current and future practices that affect greenhouse gas emissions from tailings ponds and presents a few facts that contrast with assumptions commonly made in literature regarding fugitive emissions from oil sands mines. Part II of the paper then proposes a Base GHG Model for calculating future greenhouse gas emissions. This modelling effort presents a different approach to calculate greenhouse gas emissions from ponds based on fermentable substrates with a focus on diluent, which has been shown to be the most bioavailable part of tailings. Different scenarios based on the Base GHG Model show potential pathways toward lowering the Alberta...

Description

Written for the biofuel production facility or project developer, this protocol quantifies the emission reductions from the avoidance of fossil fuel consumption when the fossil fuel is replaced by biofuels on an equivalent energy potential basis. The protocol also includes reductions in greenhouse gas (GHG) emissions due to any heat/power production and electricity generation related to the process, and from the avoidance of landfilling any materials which may be diverted for conversion to biofuel. The protocol is not intended to be prescriptive, but instead serve as a generic “recipe” for biofuel facility owners and operators to follow in order to meet measurement, monitoring and GHG quantification requirements.

Description

This MOU establishes a framework within which the ministries of Environment and Sustainable Development and Transportation and the Alberta Roadbuilders and Heavy Construction Association can work together to facilitate greenhouse gas emissions reductions that enable the industry to adjust to a carbon-constrained future and help Alberta meet the targets set out in the 2008 Alberta Climate Change Strategy and the Provincial Energy Strategy.
