Green MSP Mark Ruskell begins by praising those who have lobbied and protested around this bill, saying they are a "huge strength and a huge testament".

The science shows Scotland will have used its entire carbon budget for 2C in the next ten years and there would be no turning back from that, he warns.

"This crisis demands political-risk taking, however uncomfortable it may feel."

Mr Ruskell says he is "saddened and angry" that an opportunity to deliver real change has been passed up, describing the bill as narrow legislation in which big opportunities have been missed.

Ms Beamish says: "Let's all commit today to going further as soon as we possibly can."

The Labour MSP says the Scottish government prevented proposals for a statutory long-term Just Transition Commission even coming to a vote.

She adds: "It bears repeating: those who have done the least to cause climate change and are least equipped to tackle it are the people being struck by its terrible effects first and worst."

"We have much more to build and to do."

She ends with the quote: "Treat the Earth well. It is not given to us by our parents, it was loaned to us by our children."

Claudia Beamish, closing for Labour, says her vision has been about meeting ambition and being just, adding the "climate emergency is here".

Ms Beamish praises the young climate change strikers and all the voices around the world calling on all politicians to do better, specifically the indomitable Greta Thunberg.

She says the fact is the Scottish government's interim target was not enough and she points out Scottish Labour will consult on its position, following the UK-wide party yesterday committing to net-zero emissions by 2030.

She points to her amendment, calling for a 75% cut by 2030, which was agreed to earlier.

Tory MSP Maurice Golden warns increases in global temperatures will have a devastating impact on humanity.

We should be proud of what we have achieved as a nation on emissions he says.

But our success hides a lack of progress in major areas including housing, Mr Golden argues.

He welcomes the passing of his amendment on an agricultural modernisation fund.

It is important targets are achievable, he concludes.

Ms Cunningham says when in government, you have to make sure legislation is realistic and achievable.

The climate change secretary says the transition to net-zero will require changes to everyday life and must be a national endeavour.

She insists a just transition is central to the government's approach to ensure no-one is left behind.

The minister points out the government supported the creation of a climate change citizens assembly.

Climate Change Secretary Roseanna Cunningham says Scotland has already been world-leading on climate action, highlighting emissions have already fallen 47% since the 1990 baseline.

She says the government has followed the Committee on Climate Change's advice on targets and indeed has today committed to going further on the 2030 interim target.

Scottish Green co-leader Patrick Harvie highlights in previous legislation on climate change his party has called for the government to go further, were told this was not possible and yet now those targets have been surpassed.

We were right before - is it not possible we are right again, he asks, referring to his party's rejected call for an 80% cut to emissions by 2030..

MSPs will now debate setting more ambitious climate change targets for Scotland, before voting on whether to pass the legislation that will do just that at decision time.

The Climate Change (Emissions Reduction Targets) (Scotland) Bill, external seeks to set a target of reaching net-zero emissions by 2045.

During voting on amendments to the bill, MSPs upped an interim goal to cut emissions by 75% by 2030, compared to 1990 levels, ahead of the vote.

They also agreed to create a climate change citizens assembly.

MSPs have backed an amendment to the Climate Change (Emissions Reduction Targets) (Scotland) Bill from Labour MSP Claudia Beamish, calling for a new interim target of cutting emissions by 75% by 2030.

They rejected the more ambitious 80% cut proposed by the Greens.

An amendment from Green MSP Mark Ruskell, proposing a citizens assembly on climate change, ws however unanimously backed.

Scotland's current target, set in the Climate Change Act, is to reduce emissions by 80% by 2050 compared with benchmark levels from 1990.

This bill will set the new target of net-zero by 2045, if passed, as expected, at decision time.

The signs and impacts of global warming are speeding up, the latest science on climate change, published ahead of key UN talks in New York, says.

The data, compiled by the World Meteorological Organization (WMO), says the five-year period from 2014 to 2019 is the warmest on record.

Sea-level rise has accelerated significantly over the same period, as CO2 emissions have hit new highs.

The WMO says carbon-cutting efforts have to be intensified immediately.

On to the final amendment of the day, Ms Beamish says infrastructure investment should be assessed in terms of contributions to climate targets.

Mr Ruskell says this amendment is a baby step forward but there is much more to do.

The cabinet secretary confirms her support for the amendment, explaining it fits within a wider range of measures.

Review and research programmes will help to identify steps across portfolios she explains.

MSPs back the amendment unanimously.

That ends consideration of amendments and we have a short suspension until 5.10pm.

The terms carbon neutral and net-zero are often used interchangeably but there are differences.

Carbon dioxide (CO2) is the most abundant greenhouse gas but there are others which the Scottish government counts and they are not all carbon-based.

Therefore, some climate change campaigners prefer the term net-zero as it includes not just CO2 and methane but also nitrous oxide, which is emitted during agricultural and industrial activities as well as from fossil fuels.

Simply being carbon neutral would not stop global warming because these other gases are also harmful to the atmosphere.

Perhaps an even better term would be "climate neutral".

MSPs back Claudia Beamish's just transition principle amendments.

The Labour MSP's amendment 12A is not agreed to, with 91 MSPs voting against it and only 27 voting for it.

Ms Cunningham confirms her support for all the amendments put forward, bar one which she insists would duplicate measures elsewhere.

Regarding the comments on the statutory Just Transition Commission, she says a commission already exists and she looks forward to receiving its report.

Mr Beamish replies that she is "perplexed and bewildered" by this response and hopes the government will reconsider after the Commission's report is published.

Green MSP Mark Ruskell speaks to his amendment, saying he has been very pleased to work with Claudia Beamish to embed a just transition in this bill.

Liam McArthur also stresses the "importance of taking people with us" and the Lib Dem MSP stresses the importance of a just transition.

Claudia Beamish says her next amendments are designed to embed just transition principles within the bill.

Reaching net-zero emissions will require a huge shift in everyone's way of life, she explains.

She insists questions of justice must be asked multiple times throughout this shift.

Ms Beamish argues it is "worrying" that this Scottish government will not ensure the Just Transition Commission will last beyond three years and leave it open to political change.

She criticises the government's refusal to provide a financial resolution for this legislation, explaining this meant she was unable to bring her proposal for a statutory Just Transition Commission to a vote.

I see the government's rejection of a statutory commission as a fundamental misunderstanding of the concerns of workers, communities and businesses, she states.

In June we reported the Scottish government had officially missed its target for reducing greenhouse gas emissions.

Although total emissions fell by 3.3%, Scotland's participation in the EU-wide Emissions Trading System (ETS) means adjusted emissions, used for setting targets, increased by 3.7%.

It means Scotland has officially reduced its emissions by 39.1% since 1990.

However, "source emissions", which exclude the ETS, are down 46.8%.
