This version of the model incorporates two new pathways, wood to gasoline and wood to gasoline, as well as the expansion of the natural gas production system to include unconventional sources of natural gas, such as coal bed methane and shale gas.

This work introduces and develops a new functional unit to GHGenius so that the tool can be applied to freight transportation systems that are employed to move goods. This function unit is a tonne-km, being the movement of one tonne of goods one kilometre. Previously only a unit of energy or the distance travelled were used as functional units in GHGenius. This new measure provides a reference for very different systems that are commonly used to move freight.
This work includes a new output sheet for the results. The emissions are presented for all of the GHG and CAC emissions in the model.
The modes of freight that have been included are truck, rail, marine and some preliminary information for airfreight. Multiple classes for marine transportation are presented, as there is a difference in emissions according to vessel type and size.

A small revison to the model has been made.
One of the default buttons was not working properly and the seperate gases macro has been speeded up considerably.
Neither change impacts the results from the model.

A new version of GHGenius 3.16 has been posted. Issues with the electricity conversion from secondary to primary energy on the Energy Balance sheet and the Fish Oil Biodiesel pathways were resolved.
There are minor formatting and labelling changes as well.

A new version of the model has been posted that corrected a couple small issues in version 3.16. In most cases there are no differences in the results between the models.

The latest version of GHGenius has now been posted to the website. The changes to the model are described in two new reports, one describing the addition of Algae and Jatropha as biodiesel feedstocks and the other report detailing the updates made to the data and structure of the model.
The model is available in the Download section of the website.
The reports are available on the Reports page.

Version 3.15 of GHGenius has now been posted and is available for download.
There are two reports that accompany this version. One describes the default values for the "Provincial" versions of the model and the other describes the changes made to the model to add two biomethane pathways. One of the biomethane pathways utilizes purified landfill gas and the other involves the anaerobic digestion of manure and agricultural residues.

The Office of Energy Efficiency of Natural Resources Canada is pleased to invite you to a selection of stand alone one-day users workshop on the GHGenius life cycle model . The workshops will be held on Thursday, March 5, 2009 in Edmonton, Alberta; Friday, March 6, 2009 in Calgary, Alberta; and Thursday, March 12, 2009 in Toronto, Ontario. You will need to indicate which workshop you are interested in attending if you are interested in reserving a spot.
While the workshop is offered at no charge to participants, space is limited to a maximum of 40 people for each workshop. After the 40 spaces are filled you will be placed on a waiting list in case someone cancels. If demand is high we reserve the right to limit the number of people from any single organization. Please note that there will only be a few spaces available for the Calgary workshop as those that were registered for a postponed workshop from the fall are being given priority.
To reserve a space at the workshop please email Katie.Murphy@NRCan.gc.ca. Please be sure to include your:
name;
affiliation;
telephone number;
preferred email address; and
preferred date and location.
Ms. Murphy is in the office part time but will send you a confirmation as soon as possible.
While we intend to host future GHGenius Users Workshops, no other dates or locations are scheduled at this time.

Version 3.13 of the model has been posted along with the accompanying report. There are a number of enhancements in this version including expanded capacity for modelling oil sands, regional emission factors for N2O emissions, and enhanced land use calculations.
The model is available in the Download section and the report in the Reports section of the website.
