C A COMMUNITY ENERGY AND EMISSIONS INVENTORY OBJECTIVES In its work investigating greenhouse gas emissions (GHGs), the Community E [...] Communities located on major highway thoroughfares can expect higher sales even though most of the actual consumption of fuel will take place further down the road. Communities along the TransCanada then, would likely see their fuel sales much higher than actual consumption within their municipality boundaries. iii. [...] Communities servicing large wilderness tourism areas generally will see higher‐than‐ expected fuel sales from what is actually consumed within its municipal boundaries. Communities such as Golden, for example, experience very large increases in fuel sales during the summer, although most tourists would not consume the fuel in Golden itself. iv. [...] Communities near the US or Alberta borders will likely experience lower‐than‐expected sales as consumers travel to the US or Alberta for shopping. Residents of the Northeast for instance are notorious for their cross‐border shopping, many choosing to make weekly or biweekly excursions to Alberta towns solely to save on taxes.3 Similarly, smaller communities without large re [...] In the EMME Model, long‐term behavioural patterns are highly dependent on these input data. As a consequence, many behavioural changes since the last update (in this case, 2001) are not fully captured and thus may not reflect accurately changes in VKT. In a nutshell, this means that relying on EMME results to determine changes in VKT on an annual basis is problematic and because
