Referencing TSC 1.12 Electricity generation from fossil gaseous fuels, Green Criteria include “The activity meets the following criteria: CCS is eligible as a lever for the activity to meet the green thresholds as defined in Table 1”; Amber Criteria include “New or retrofit of existing facilities to meet Amber threshold”. Given that CCS is commonly adopted in Singapore, is it compulsory to meet the criteria for CCS? What if the power plant meets the green thresholds without using CCS?

CCS is not compulsory, especially when the plant meets the threshold. Further, per part 1 (see below), this is an optionality criteria provided.

Part 1
Qn: Does ‘The activity meets the following criteria’ mean that it needs to meet all of the following criteria or just one of the following criteria?
The activity would have to meet all criteria (except for CCS, where it’s an additional optionality provided), as these criteria are all interconnected. For example, the second and third criteria relate to the certification standard required to be observed for the calculation of the first criterion.
