I might be missing something, but I am still not 100 per cent clear about where private investment relating to carbon gets a return, if the market is not to be highly regulated. Are we in danger of repeating what happened when we had subsidy quotas in farming? People started to trade in quotas rather than in livestock, for example. They sold quotas, and we created a whole new economy of quotas.

In our evidence session on 24 November, David Finlay from the Ethical Dairy said:

“The Ethical Dairy is sequestering 5 tonnes per hectare per year, and we are emitting 4.5 tonnes per hectare per year, according to Agrecalc. If I sell that 5 tonnes of carbon credit, I am no longer net zero. I do not understand how the industry can sell its carbon credit without becoming carbon positive.”—[Official Report, Rural Affairs, Islands and Natural Environment Committee, 24 November 2021; c 14.]

The chair of the Scottish Land Commission has said:

“We have had a number of concerns raised recently from people across different land use sectors and by stakeholders of the Tenant Farming Advisory Forum about the pressures farmers and crofters are facing to sign over carbon rights.

This is a fledgling market and there is a risk decisions are being made without full awareness of the implications for individual land managers. I would encourage landowners and land managers to exercise caution when considering transferring carbon rights or options until there is greater clarity over issues such as ownership of the rights and the need to retain them in offsetting their own business emissions in the future.”

I know that Eilidh Mactaggart said that the industry is a fledgling one, but is that not all the more reason to ensure that we get this right?

I will interrupt you on that point.

Given what you have just said, do you believe that we should have land grades as the prerequisite for what will be planted? Are you suggesting that good-quality arable land should not be used for tree planting? Are you seeking specific grading of land for specific investments?

I am sorry, Eilidh, but can I—

That goes back to my earlier point to you. Dieter Helm mentioned having a type of trust fund organisation that makes such investment decisions. You said that you do not have the expertise to deal with that—I get that—but that raises the question of what we are trying to achieve. We want to achieve net zero and a return for investors, and we want to be able to keep people on the land. It seems to me that there needs to be a mechanism for us to bring all that together.

That is just a statement; it is not a question for you, Eilidh.

You have raised something that I had not thought about. I had never heard of the Civil Contingencies Act 2004. I assumed that the act was about foot and mouth when you said that it was from the early 2000s.

The 2004 act is there, and we currently have the Coronavirus Act 2020. I go back to what you said about the need to look at having some sort of public emergency act after this is all done and dusted. Coronavirus has affected not only people’s health. Should we have looked at a broader picture and used the 2004 act? The pandemic has affected business, freedoms, poverty and every aspect of society. Would it not have made more sense to use the 2004 act, which relates to civil contingencies, rather than creating an act that relates to health?

I apologise for being an absolute pedant here, but if we had gone down the route of using the 2004 act, would it not have been the same principle that those powers would have been devolved for the period of time to allow the devolved Administrations to use them?

I will talk about vaccine uptake and where there is a bit of hesitancy. My points come from questions that members of the public have put to the committee.

A number of people have been in touch about women’s reproductive health and the vaccine. Some are asking whether fertility is impacted in any way by having the vaccine. I know that we have covered that before but, if we are getting the questions, it is clear that the message still has not got out to some individuals.

Others have asked whether breastfeeding women will be eligible for the booster vaccine, and whether health and social care partnerships and midwives have appropriate information and training on eligibility for the vaccine. Parents have highlighted that there is inconsistency of knowledge and understanding in HSCPs across Scotland in relation to breastfeeding and vaccine eligibility.

Finally, I have a constituent who is very concerned about getting the vaccine because she is on cancer drugs. I ask Jason Leitch to comment on that.

May I make a point, convener? That would not be a false negative; it would be a fraudulent negative.

I will be brief because I have to go to the chamber, but I will comment on my use of the word “fraudulent”. Christmas is coming up, and if someone who is 18, 19 or 20 is going out with their mates and they do not feel bad but their test comes up positive, they might just chance their luck because they feel okay. I have a genuine concern about that. That has always been my concern about going down this road.
