Considerations when mapping new datasets

[dgarijo]

After discussing with @m-markovic today, we need to consider the following changes (grouping issues here, but happy to separate them in issues at a later stage):

• We need to add a version of the conversion factors without the CO2e equivalent. Right now we have the numbers in co2e, which implicitly have a global warming potential indicator!
• We will need to indicate that a ECF aggregates other ECF
• We need to represent conversion factors and emission conversion factor. Global warming potential is a set of conversion factors (multipliers) that need to appear! If we have co2eq, then there should be a link to a gwp factor
• Move into cleaner source and target as we discussed with Stefano
