37 add indicators for climate finance

[Mattie-P]

Following on from discussion, we have added indicators for:

• total climate allocable ODA
• mitigation significant (1)
• mitigation principal (2)
• mitigation not targetted (0)
• mitigation not screened (99)
• mitigation total (1+2)
• adaptation significant (1)
• adaptation principal (2)
• adaptation not targetted (0)
• adaptation not screened (99)
• adaptation total (1+2)
• overlap total (1) --> In theory, we only need to combine the significant indicators as the activities marked as principal should not have any other focus.
