The details of the report
show that declines in manufacturing
and mining, quarrying
and oil and gas extraction were the reasons for the negative month - on - month reading, with the 0.8 % contraction in the mining, quarrying,
and oil and gas extraction sector being the main drag as well as the most disappointing since it marked the third consecutive monthly decline.
On the contrary, Figure 1 is a conservative estimate of potential emissions from tar sands because: the economically extractable amount grows with technology development
and oil price; the total tar sands resource is larger than the known resource, possibly much larger;
extraction of tar sands
oil uses conventional
oil and gas, which will
show up as additions to the purple bars in Figure 1; development of tar sands will destroy overlying forest
and prairie ecology, emitting biospheric CO2 to the atmosphere.
