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.
