EMISSION FACTORS 2020 DATABASE DOCUMENTATION
kWh of electricity and heat (gCO2 per kWh) GHGKWHHIN This ratio is based on total CO2 emissions from fossil fuels consumed for electricity and heat generation divided by the output of electricity and heat (in kWh) from all fossil and non-fossil sources It includes electricity-only plants, combined heat and power plants, and heat-only plants
CARBON DIOXIDE (CO INFORMATION SHEET EMISSION INTENSITIES
To help you calculate the carbon emissions associated with your electricity use, we provide several options for CO 2 intensities to meet your needs 1 The basic calculation: lbs/kWh x annual kWh = lbs of CO 2 Intensities provided here are based on CO 2 emissions from all electric generation, including biomass and on-site, distributed solar 2
Carbon Footprint of Electricity Generation
budgets Average emissions from electricity generation fell from 718 gCO 2 eq/kWh in 1990 to 500 gCO 2 eq/kWh in 2008 (Box 1) 2 The Committee on Climate Change (CCC) recommends a further reduction to just 50 gCO 2 eq/kWh by 2030 to support achievement of the national budgets 3 These figures consider only the emissions caused directly at

Energy Systems - IPCC
Its specific emissions are below 100 gCO 2 eq per kWh on a lifecycle basis and with more than 400 operational nuclear reactors worldwide, nuclear electricity represented 11 of the world’s electricity genera - tion in 2012, down from a high of 17 in 1993 Pricing the externali - ties of GHG emissions (carbon pricing) could improve the
The Netherlands: list of fuels and standard CO emission factors
For national monitoring of greenhouse gas emissions under the framework of the UN Climate Change Agreement (UNFCCC) and monitoring at corporate level for the European CO 2 emissions trade, international agreem ents state that each country must draw up a national list of defined fuels and standard CO 2 emission factors This is based on the IPCC
Among the lowest greenhouse gas emissions of all electricity
Based on a life cycle analysis, net GHG emissions from Québec hydropower are significantly lower than electricity generation from natural gas and coal, and on par with wind 1 UNDERSTANDING QUÉBEC HYDROPOWER AMONG THE LOWEST GREENHOUSE GAS EMISSIONS OF ALL ELECTRICITY GENERATION OPTIONS GHG EMISSIONS Power generation options (g CO 2 eq */kWh)
Comparison of Lifecycle Greenhouse Gas Emissions of Various
Accounting for emissions from all phases of the project (construction, operation, and decommissioning) is called a lifecycle approach Normalizing the lifecycle emissions with electrical generation allows for a fair comparison of the different generation methods on a per gigawatt-hour basis The lower the value, the less GHG emissions are
