US American (and self-proclaimed Albertan), trees absorb carbon dioxide when they grow and release it over the life of whatever their wood is used for.  As long as the trees are replanted and the land not repurposed (for urban development, industry, agriculture) carbon balance is maintained.  Hydrocarbons aren't like that.  They are a potentially one way ticket to sequestration but form very slowly.  That industry pulls who knows how many 1000s of years of fossilized fuel out of the ground each year.
