Earning carbon credits by users of Edencrete possible?, page-19

Most schemes have provision for people to propose methodologies so that's always an option for them. The estimation of CO2 savings for the aspects you mention would be fairly straightforward, but would need to be validated through a pilot and monitoring.

One thing to keep in mind, in relation to what you're thinking, is that schemes tend to target upstream emission sources because there are fewer of them and that reduces the costs of monitoring and compliance. For example, schemes that cover energy sector emissions will tend to favour generation efficiency over end-use efficiency because there is one source versus thousands. It is more difficult to attribute emission reductions to an end user. The NSW scheme did it 15-20 years ago, but they had to make many assumptions and allow deemed emission reductions which opened to scheme to rorting by people delivering CFLs to households in exchange for a signature signing over the right to the deemed abatement, but the lights were never even installed. Different situation I know, but it's just an example of why any emission reductions from Edencrete are likely to be attributed to the manufacturer or project developer than end users.
