Can I assume that my 40% energy savings is also 40% in GHG given that I have only one source of energy which is electricity...
Note, I'm using local emission factor for both baseline and proposed.
Note. My project is under V4 but registered after March 2024.

Hi Omar,
Possibly yes, but... you didn't mention if you are including renewables and if they are on-site vs off-site in your 40% energy savings. So that's one aspect which is noted in the calcs and how those can be claimed for GHG savings. See Option 1 Table 1 & 2 Notes for details.
The other "but" is an annualized emissions factor for your Scope 2 electricity usage will give you this kind of over simplification where 40% kWh reduction is 40% CO2e saving. GBCI doesn't require you do hourly emissions factor analyses (either average-hourly or marginal-hourly) in v4 or v4.1 but this is in the v4.1 Ref Guide under Electrictiy Hourly Emissions Factors.
Cheers,
Jamy
