Ms Haughey says the government has continued to increase investment into mental health services.

Diabetes Scotland is calling for more funds to ensure people with diabetes can access psychological support.

Mental Health Minister Clare Haughey points to the establishment of on advisory group on healthy body image.

Mr Greene seeks more information on this group.

The minister says the group will focus on developing a charter pledge on healthy body image for young people, looking at options on how professionals can support this and providing the Scottish government with advice on the next steps.

The Tory MSP asks what steps can be taken around the reporting of online abuse and increasing the diversity of body types people see.

Ms Haughey says the government has committed to publishing advice on healthy social media use.

The Committee on Climate Change has called for a UK wide heating strategy.

CCC CEO Chis Stark told MSPs: "If there is a test of whether we are serious, it's heating.

"I would really like to see a UK wide strategy for domestic heat now."

The CCC also welcomed the Scottish government's quick acceptance of its target for achieving net-zero green house gas emission by 2045.

Earlier this month the committee urged that Scotland set the target five years ahead of the UK as a whole.

The Scottish government almost instantly announced it would legislate to meet the target after receiving fresh advice from the expert panel.

Mr Stark said: "I'm delighted our recommendation was accepted so early."

There is a more integrated approach in Scotland about what needs to be done, Mr Stark says.

Climate change has to be given a much more prominent role, he argues.

Prof Piers Forster adds that the conversation must be taken out into the community.

Prof Keith Bell asks if government departments have the capacity to offer analysis and expertise on this, and Chris Stark replies it does not at the moment.

Gillian Martin thanks all of the members of the Committee on Climate Change for giving evidence and the session draws to a close.

Mr Stark says: "We haven't been fighting with Nigel Lawson, instead we've been having a good discussion with Extinction Rebellion."

This is remarkable progress, he adds.

The CCC CEO points out there is still a feeling something could be done quicker but says there needs to be a credible strategy.

"This report is as ambitious as we have ever been on the committee and it does give us a platform to say we are among the most ambitious countries in the world in terms of climate change."

Saying this is an unambitious report is hugely off and if the Scottish and UK government meets the targets that would be an enormous task, he concludes.

Mark Ruskell suggests that meeting the 1.5C limit is a 50:50 chance even with these targets, which he says is a "big gamble".

Mr Stark says there is not a pathway that deliver more than that.

This is not us conceding, this is as ambitious as we can be just now he adds.

Mr Ruskell asks about the Scottish government's response to the CCC report.

Mr Stark replies: "I'm delighted our recommendation was accepted so early."

The CCC CEO says he thinks the Scottish government accepted them at two minutes past midnight and jokes "we'll allow them 60 seconds".

It matters immensely that they chose to accept the recommendations so quickly, he adds.

"That to my mind has been fantastic in Scotland."

Prof Bell agrees: "It's a fantastic signal."

There is a real need to ensure we reach carbon-zero in a way that is not socially regressive and does not impact competitiveness, Mr Stark insists.

He argues there is a need for HM Treasury to look at this.

We will not manage to hit the targets if the costs are just lumped onto consumer electricity bills, he warns.

Mr Stark says: "We are relying on a mixture of technological change and behavioural change to achieve net-zero."

We're not going to achieve this without engaging people, he says.

To achieve the target we must act through

• 38% low carbon technologies
• 9% societal change
• rest through a combination of efforts

Prof Piers Forster praises the establishment of the Just Transition Commission as it will ensure early actions are taken.

Mr Stark says infrastructure needs more active thought and active planning.

We are forecasting a doubling of electricity demand and that is a big infrastructure requirement the CCC CEO explains.

Improving the housing stock is probably the biggest requirement and Scotland is performing slightly better on this than the rest of the UK, he adds.

Green MSP Mark Ruskell asks if we can continue to extract oil and gas at the current rates and still meet the net-zero target by 2045.

"This is one of the most difficult areas for us," replies Chris Stark.

The CCC CEO adds the short answer to this is we probably can but we don't have the things in place to allow this.

Mr Stark says the extractive industries we have at the moment are not compatible with net-zero.

He points out the alternatives are more expensive, but that does not mean we shouldn't pursue them.

"There can be world where we continue to extract oil and gas, but oil and gas cannot be burned unabated."

Mr Carson turns to studies indicating meat consumption needs to drop by 50%, which he warns would "decimate" the agricultural industry.

Mr Stark explains that reducing meat consumption is just one option for tackling climate change.

He says the proposed 20% cut in consumption is in line with social trends, rather than anything to do with policy, when looking at dietary differences between generations.

Such a cut would also free up land for other climate interventions, he adds.

Tory MSP Finlay Carson moves on to agriculture, livestock breeding and diets.

Chris Stark calls for an honest discussion about it and says that has not happened yet.

There seems to be more of an open discussion at Westminster about this than here in Scotland, particularly with Michael Gove's policy of public money for public goods, he points out.

• Join us tomorrow morning as the UK environment secretary gives evidence to MSPs twice.

The CCC CEO points out the agriculture community understands climate change more than any other community.

They must not be seen as the enemy, but the set of incentives for farmers beyond food production must be introduced he adds.
