1. Fixed Process Emissions
2. Issue Implementing the fixed process emission provisions in framework
Recalling from Framework that:
“Predefined fixed process emissions would have a 0% reduction in emission intensity from 2006 levels in 2010”
“Fixed process emissions are emissions that are tied to production and for which there is no alternative technology that will reduce them. The only way to reduce these emissions is to reduce production.”
“Fixed process emissions will have to be determined on the basis of the characteristics of firms and sectors.”
3. What are fixed process emissions Most industrial GHG emissions are from:
Fuel combustion
Burning of fossil fuels to produce energy
Processes
Chemical reactions in production processes or other releases of GHGs during the production process.
Differing ability to reduce emissions
Fuel combustion emissions can be reduced through fuel efficiency and the use of low emitting fuels
Some process emissions can be reduced through the use of alternate processes and improved process control.
Other process emissions are not controllable
It is these process emissions that not controllable with alternate technologies that are considered fixed process emissions.
4. What are fixed process emissions: Example Cement
Cement is made by heating calcium carbonate (CaCO3), found in limestone at high temperatures to produce clinker (mainly calcium oxide) the main ingredient of cement.
In the process as calcium carbonate converts to calcium oxide (CaO), CO2 is released from the calcium carbonate.
CaCO3? CaO + CO2.
CO2 is released at a rate of 0.44t CO2/t Clinker.
Combustion is the other reaction releasing CO2 in the process.
Heat from combustion is needed to drive the reaction. This is not considered a fixed process emission because it is intended to produce energy for the process.
5. Fixed process emissions as estimated and presented in Framework
6. Framework: Background Estimates in Framework of fixed process emissions (winter 2007) were based on previous work by the departments.
Have generally followed a narrow interpretation of what are fixed process emissions.
Recognizing the risk of slippage on emission reductions if the interpretation is broadened.
Department consulted with industry in the spring and summer of 2007 on fixed process emissions in their sectors.
7. Status Designation as fixed process emission is based on decision on whether facilities in that sector have the potential to reduce the process emission (for ex., through efficiencies, alternate technologies etc).
Analysis is underway to confirm the specific fixed processes in each sector.
