Base year / Verification process

Hello, we already have an emissions reduction target defined in 2014 to achieve in 2030, but we began the verification process with a third party audit in 2019 (only scope 1 and 2), maybe it is better to establish a new reduction target with this year (we include the emissions of our commercial and productive sites.
We want to select this option in the SME Target Setting Letter.

Well-below 2°C option Commits to reduce absolute scope 1 and scope 2 GHG emissions 30% by 2030 from a 2018 base-year, and to measure and reduce its scope 3 emissions.

Can we use 2019 as the base year for this option?
