Sentences with phrase «upstream emissions»
"Upstream emissions" refers to the greenhouse gas emissions that occur during the extraction, production, and transportation processes of a particular product or activity. It focuses on considering the environmental impact from the very beginning stages of a product's life cycle. Full definition

The charts also show a breakdown of total emissions into tailpipe emissions at point - of - use (CO2: 2.15 tonnes, NOx + PMs: 6.3 kilograms), together with upstream emissions generated during fuel and vehicle production.
But the legislation introduced by the B.C. Liberals fails to address upstream emissions from natural gas production.
According to economist Trevor Tombe, the average levy on upstream emissions from bitumen extraction will be about $ 2.25 per barrel at a carbon price of $ 30 / tCO2e.
First, upstream emissions during mining of coal or extraction of gas continue.
The emissions from consumer products also dwarfed those from the production of oil and gas, called upstream emissions.
All of these studies are reporting upstream emission estimates that are 10 - to 20-fold higher than those reported in this new paper by the Allen and colleagues.
Most studies have shown that more than half of the methane leakage from natural gas comes from drilling sites and gas processing plants (i.e. upstream emissions), with the remainder coming from pipelines and storage systems (i.e. downstream emission).
Higher capture rates are more costly and would not eliminate upstream emissions, equivalent to 23 - 42gCO2e / kWh, still well above the numbers for nuclear, wind or solar.
Further, due to growing output, total emissions from the oil sands continue to increase despite the reduced CI; total upstream emissions were roughly 65 MtCO2e, or 9 % of Canada's emissions, in 2010.
That's true even when one counts the energy - intensive tar sands extraction and processing — and, of course, there are plenty of upstream emissions associated with coal mining that I've left out of the equation here.
... And 11 % in Full Lifecycle Analysis But that's just upstream emissions: On a full lifecycle basis, the report concludes, «emission reduction potential is likely in the 7 - 11 % range.»
Even factoring upstream emissions of methane from flaring and leaks (that is, leaks and burning of gas before the end user flips the switch) natural gas emits far less greenhouse gases than does burning coal.
The system boundary for their lifecycle analysis included direct consumption of all primary fuels and electricity at production sites; processing of gas for H2 generation; emissions associated with direct land - use change; flaring from upgraders; emissions from tailings ponds (for mining); upstream emissions from natural gas production; emissions from crude bitumen batteries from in situ production; and emissions from directly producing the fuels in both mining and in situ production.
Hydrogen can be made with no upstream emissions using renewable energy to separate hydrogen from a water molecule in a process called electrolysis.
Their conclusion is that upstream emissions are low, 0.42 % of natural gas production (lower than we estimated for shale gas back in our April 2011 paper, and towards the low end of what we estimated for conventional natural gas).
Moreover, even when emissions from the generation of electricity (upstream emissions) were considered, electric vehicles produced 21 times less carbon dioxide equivalent emissions per year than their gasoline - powered alternatives.
The increase is entirely on the upstream emissions side.
Although the burning of fossil fuels generates most of the potential emissions from most reserves, emissions from production and processing operations (known as «upstream emissions») can also be important, depending on the reserve type and technologies used.
Even with Alberta's oil sands cap in place, National Energy Board (NEB) projections for oil and gas production growth show that upstream emissions will increase greatly, to the point that a 49 % reduction in emissions from the rest of Canada's economy would be required to meet our Paris targets.
These upstream emissions are expected to increase as the world's conventional fields get depleted and companies turn to fields that require more energy to extract, such as oil sands.
Astonishingly, she claims that this will have no effect on future production or upstream emissions.
Similarly, bio-derived fuels could be an abatement option, but only if it can be ensured that upstream emissions — in particular, land use change while growing biomass — does not impact wider potential savings.
Generally speaking, upstream emissions are small relative to consumption emissions, but, in the case of the oil sands, emissions associated with the production of the bitumen are much higher than for conventional oils.
Only 50 % Reduction in Upstream Emissions Possible According to the report Carbon Capture and Storage in the Alberta Tar Sands, CCS «has limited potential to reduce upstream emissions to levels comparable with the average for conventional oil,» with «even the most optimistic estimates from industry experts» showing reductions in the 10 - 30 % range in the medium term and up to 50 % in the long term.
