Mr Golden uses his motion to mark the WWF Earth Hour 2017.

The Earth Hour took place at 8.30pm on 25 March when Scotland and the rest of the UK joined more than 175 countries in switching of the lights.

The Tory MSP says everyone should take part in events like Earth Hour to help raise awareness of climate change.

On 25 March major landmarks around the world turned out their lights to mark Earth Hour, an event that draws attention to climate change.

Around 170 countries and territories took part on the Saturday, by turning off non-essential lights at 20:30 local time.

The event, which reached its 10th anniversary this year, is organised by conservation group WWF.

"We started Earth Hour in 2007 to show leaders that climate change was an issue people cared about," said coordinator Siddarth Das.

"For that symbolic moment to turn into the global movement it is today, is really humbling and speaks volumes about the powerful role of people in issues that affect their lives."

MSPs will now vote on motion and amendments from the debate on child tax credits and the 'rape clause' and the general principles of the Air Departure Tax Bill.

Green MSP Patrick Harvie raises a point of order about the financial resolution for the Air Departure Bill.

Mr Harvie says the financial memorandum does not go into the taxation revenue impacts of the bill and he asks if the standing orders are still adequate.

Presiding Officer Ken Macintosh say there were other considerations in the bill that allowed a financial resolution, but concedes Mr Harvie raises an interesting point.

Mr Mackay says this is about devolution and the transfer of powers and, for that reason, it would be wrong of the liberals to oppose it at this stage. 

The finance secretary says there will be further engagement around the tax rates and bands.

Scottish Green co-conevener Patrick Harvie says he has set out factors that should be included to "put pinciple into the bill" and asks why the finance secretary would find this uncomfortable. 

Mr Mackay says decision will be informed by analysis and he will continue to engage with parties.

He says the bill will be used to stimulate the economy and that the Scottish government is delivering on its environmental objectives.

Finance Secretary Derek Mackay says this has been a very consensual debate and he says he will reflect on the contributions from across the chamber.

Mr Mackay says he accepts Labour and the Tories backing the general principles of the bill does not mean they back the government's policy on the level of air departure tax.

He says the SNP policy of a 50% cut  in ADT will increase connectivity and stimulate the economy.

The finance secretary says it should be welcomed that the government is taking forward the call for independent analysis.

Tory MSP Dean Lockhart says there has been a range of different views on how Scotland can use ADT.

Mr Lockhart says the bill lacks detail in a number of important areas and there are no details of the rates that will apply.

The Tory MSP says there is also no detail of the economic and environmental impacts.

He says the Tories support an overall reduction of ADT tax but that they would prefer to see a targeted reduction in long hall flights for economic benefits.

Mr Lockhart says he welcomes the government's commitment to undertake a full analysis of its plans. 

Labour MSP James Kelly says clearly the Air Departure Tax Bill is a logical conclusion from the Smith Commission and he says his party supports having the tax in place.

Mr Kelly says, however, the Scottish government wants to reduce the tax by 50% during this parliament and ultimately abolish it.

He says evidence for this has been "wholly inadequate" and the 50% reduction will lead to a revenue reduction of £189m.

The Labour MSP says Derek Mackay will bring Stage 3 of the ADT bill before there is any proper analysis.

He questions the fairness of the policy saying it is "wholly unfair".

Mr Kelly also asks how this policy fits with reducing carbon emissions as air travel will increase.
