Location: CA-QC - Canada, Québec
This dataset represents the production of heat from natural gas at boiler condensing modulating >100kW in Quebec.This is an adaptation for Quebec from the corresponding global dataset. Only time period, annual production volume and heating value have been modified. Uncertainties have been adjusted accordingly.

NOx and CO emissions derived from measurements under controlled conditions; no adjustment to real operation made due to lack of information. Other emission data from different references.
None
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
