The crude stock, whether heavy of light, is not relevant to the CO2 emission produced. Because the controlling factor is the refined product which is combusted.

To refine heavy crude oil, which has many carbons and few hydrogens, refiners like Chevron mix the heavy crude with natural gas, which has many hydrogens and few carbons. The resulting refined product has a nearly constant ratio of carbon to hydrogen regardless of the original crude oil used.

In contrast, burning coal will create more CO2 per BTU produced as essentially all of the energy is coming from carbon combustion with virtually no energy derived from hydrogen combustion.

Water can be used as a hydrogen donor, instead of natural gas, but this process requires more energy. I suspect that using water as a hydrogen donor would create more CO2 emissions in total due to the extra energy required.
