Labour MSP Claudia Beamish insists the 2030 interim target should be a 76% reduction against 1990 levels, based on the current inventory.

We cannot accept legislation with caveats to be held in good faith, she adds, calling for protection against a lack of clarity having consequences in the future - i.e. a change of government.

Ms Cunningham says the key question around the amendments in this group is whether we trust the Committee on Climate Change or not.

An emissions inventory is a database that lists, by source, the amount of air pollutants discharged into the atmosphere during a year or other time period.

According to the Committee on Climate Change, external inventory improvements are designed to increase the transparency, accuracy, consistency, comparability, and completeness of the inventory.

Changes to the emissions inventory published in 2018 mainly affected the forestry, shipping, agriculture and waste sectors:

Emissions from degrading peatlands will be included for the first time going forward.

These changes will lead to a change in the targets..

Green MSP Mark Ruskell says his amendment is about changing the target date to 2042.

It's about bringing absolute clarity to the bill, not about changing the effort he explains.

The Green MSP says there is a lack of coherence around the emissions inventory at present and getting to 2045 requires the same effort to reach 2042 and warns against the risk of revising down the targets.

The targets should be set on the current inventory, he adds.

The cabinet secretary insists the 2045 target relies on the UK government also setting a net-zero target for 2050 and she welcomes confirmation last week that it would do so.

Mr Ruskell's amendment to set the target three years earlier at 2042 goes against the Committee on Climate Change's advice that 2045 is the highest possible target, she insists.

She goes on to highlight other amendments which also go against the CCC's analysis.

Acknowledging how long she has been speaking to the 51 amendments in the group, she concludes saying this is a long session but the key one.

Claudia Beamish's amendment relates to the CCC recommendation for a 2030 interim target:

• Scotland should set a target to reduce emissions by 66% in 2030 on 1990 levels,supported by a target for a 56% reduction by 2020. These reductions would keep open the option to achieve more ambitious levels of emissions reduction by 2050 (e.g. 90% the reduction discussed above), and would allow Scotland to increase its overall ambition (and set it into legislation) at a later date, if required. An interim 2040 target should be set to be consistent with the final 2050 ambition.

Ms Beamish seeks to change the 66% target to 76%.

We now move to the crucial amendments relating to resetting the target for net-zero emissions as 2045.

Ms Cunningham's amendment does just that, while Green MSP Mark Ruskell will try to set the target earlier at 2042.

The Scottish government committed to net-zero greenhouse gas emissions by 2045, five years ahead of the UK as a whole.

It followed net-zero recommendations from the UK Committee on Climate Change (CCC).

Green MSP Mark Ruskell says the climate justice principles are important, particularly in recognising Scotland's "debt" to the world as a developed nation.

Environment Secretary Roseanna Cunningham says she is sympathetic to Ms Beamish's amendment and is supportive of the principles.

She insists there is a considerable overlap between this amendment and one of her own to be voted on at a later stage.

Ms Cunningham points to issues she has with the member's amendment but offers to work with her on improving it ahead of stage 3.

I have no doubt that all of the amendments in the grouping have good intentions, but there is a risk of overburdening the legislation with good intentions she suggests.

Claudia Beamish withdraws her amendment, as does Maurice Golden.

Tory MSP Maurice Golden says his amendment seeks clear objectives on the face of the bill.

Labour MSP Claudia Beamish begins with the first amendment of the day, explaining she hopes to ensure the delivery of climate justice.

It would require Scottish ministers and the Committee on Climate Change to recognise principles of climate justice (detailed below) as it considers action, she says.

The Scottish government will legislate to reduce greenhouse gas emissions to net-zero by 2045 after receiving fresh advice from an expert panel.

The Committee on Climate Change, external (CCC) urged that Scotland set the target five years ahead of the UK as a whole.

The panel says Scotland has more potential sites for carbon capture and a greater landmass for tree planting.

It came after a report to the UN last year urged the world to go "further and faster" in tackling climate change.
