For the ‘Diesel Combustion in Construction Equipment (no transport)’ option in the Equipment category and ‘Fuel installations’ category, the construction GWP for 1 litre of diesel has changed significantly between the UK V13 LCI source and the UK V18 LCI source.
It would be useful to understand the reasons behind this change and how the decarbonisation of this emissions source has come about.
The LCI sources are constantly getting updated and refined as more information gets collected over time. Older datasets may also have errors which is fixed in newer datasets. As such, we believe that the newer dataset may be more accurate and always recommend using the latest dataset as opposed to the older dataset.
