Climate Change Impact: 

- Alberta accounts for almost 40 per cent of Canada's greenhouse gas emissions
- Oil sands release greenhouse gasses such as nitrogen oxide (NOx), sulphur dioxide (SO2), hydrogen sulphide (H2S), ozone and fine particulate matter
- A recent study by the Pembina Institute, an Alberta-based environment think tank, reported that oil sands development is "the single largest contributor to greenhouse gas emissions growth in Canada," and is expected to contribute to almost half of Canada's emissions growth in the next few years
-Tar sands minning procedure releases 3 times the CO2 than regular oil production

- Kyoto Agreement is an international agreement (including Canada) to lower greenhouse gas emissions and Alberta's oil sand are allowing that a agreement sink under our nations hands
