Regarding additionality: does this mean that, for purposes of the offset, you’re trusting that the technicians you train wouldn’t have properly recovered the refridgerant anyway? Do you have some rough statistics to suggest this? There’s also the issue of self-selection: the techs that work with you are probably more likely than the general population to be properly reclaiming already, for instance since the marginal gain from your program is greater for them (same money for no additional work). Have you considered this?
