Environment and Climate Change Secretary Roseanna Cunningham says the success of Earth Hour is obvious with the participation of hundreds of millions of people across the planet.
Ms Cunningham says the Scottish government switched of a number of buildings.
The minister has enshrined long term carbon emission reductions in legislation, which is quite rare.
She highlights the improved climate change targets in the forthcoming Climate Change Bill.
The Scottish government has outlined a new target of reducing greenhouse gas emissions by 66% by 2032.
The minister also highlights the draft climate change plan for the next 15 years at Holyrood.
She concludes with a poem and then says "fixing climate change will stop the earth greeting".
Conservative MSP John Scott says all of the events around Earth Hour are important as they inspire our school children.
Mr Scotts says low carbon policies are more important than ever and adds there is much to be done.
SNP MSP Ash Dehnam says Scotland has done a large amount in tackling climate change.
Ms Dehham says Earth Hour is our opportunity to reaffirm our protection of the planet.
She praises WWF for the venture.
Green MSP Mark Ruskell says it is important to recognise what Earth Hour is and is not.
Mr Ruskell says it is clearly not a way to reduce electricity consumption directly.
The Green MSP says it is about raising awareness which can be a springboard for further action.
He calls for "true energy democracy" and he says he sees a bright future in the darkness of the Earth Hour.
Labour MSP Claudia Beamish says that Earth Hour is a "brilliant idea".
Ms Beamish says a transition to a low carbon economy must be a just transition and people in Scotland need to be ensured that jobs will be created in the low carbon economy.
Tory MSP Finlay Carson says "it is all too easy to forget or shrug off our responsibilities" to protect the environment.
"We must not allow that to happen," he says.
SNP MSP Graeme Dey says he is delighted Scotland is making good progress to meeting its climate change targets.
Mr Dey says behavioural change is key to tackling climate change.
He says there must be progress made on the actions agreed to in Paris.
Mr Golden says the old ways are not working anymore and Scotland needs new ideas.
The world is changing "for the sake of our children lets make sure it is changing for the better," he says.
From the WWF website:
"WWF is the world’s leading independent conservation organisation. Our mission is to create a world where people and wildlife can thrive together.
"To achieve our mission, we're finding ways to help transform the future for the world’s wildlife, rivers, forests and seas; pushing for a reduction in carbon emissions that will avoid catastrophic climate change; and pressing for measures to help people live sustainably, within the means of our one planet.
"We’re acting now to make this happen."
Tory MSP Maurice Golden says at 20:30 on the 25 March many around Scotland joined those around the world to mark Earth Hour by putting off their lights.
Mr Golden says Earth Hour has been embraced around the globe.
The Tory MSP says he looked like an extra from the shining as he posted a picture of himself that evening on his Twitter page.
He says 1200 schools across Scotland took part in earth hour and their involvement is testament to the level of engagement.
Mr Golden says there is much to be proud of in Scotland when it comes to combating climate change.
He says climate change cuts across party lines and he welcomes the opportunity to hear from others across the chamber.
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."
Tory MSP Maurice Golden will now lead a debate entitled 'WWF Earth Hour 2017".
111 MSPs back the financial resolution, 4 voted against and there were 6 abstentions.
MSPs back the general principles of the Air Departure Tax (Scotland) Bill
112 MSPs backed it, 4 voted against and there were 6 abstentions.
The government motion on child tax credit cuts and the 'rape clause', as amended, is agreed to with 91 MSPs backing it and 31 against.
The Green amendment on child tax credits and 'rape clause' is agreed to with 91 MSPs backing it and 31 against.
The Labour amendment on child tax credit cuts and the 'rape clause' is agreed to with 91 MSPs backing it and with 31 against.
The Tory amendment on child tax credit cuts and the 'rape clause' is not agreed to, with 31 MSPs backing it and 91 against.
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.
