Will Greenwood is backing England to sparkle under the lights in Paris on Saturday - as he sits in the darkness to support Earth Hour.
The former England international and Sky Sports expert is excited by the prospects of a Grand Slam title for Eddie Jones' side, but is also urging everyone to simultaneously get behind the global initiative organised by the World Wide Fund for Nature.
The event is held worldwide annually to encourage individuals, communities and businesses to turn off their non-essential lights for one hour as a symbol of their commitment to the planet.
Greenwood told Sky Sports News HQ: "Sky as a company have got a long history and long heritage of supporting climate change, with a six-year campaign in and around the rain forest. Earth Hour has been going since 2007 and in 2015 10 million people took part in over 172 countries. But what does Earth Hour mean?
"Between 8.30 and 9.30 tonight switch off as many lights as possible. I know people are saying England are playing France to win the Grand Slam but I'll be watching it at home with simply the TV on and the rest of the house in darkness.
"Iconic landmarks like Buckingham Palace and the Eiffel Tower will be taking part. Around the world many sporting stadiums will simply press 'Click, turn, off' with an understanding that even the smallest changes can make the biggest difference.
"Climate change is responsible for the extinction of species, and also really at the heart of why poverty takes place around the world so it's hugely important initiative.
"Sky have always grasped the bull by the horns it terms of being proactive in looking after our climate and we are hoping that as many of the 21m Sky custoners as possible tonight between 8.30-930 if they are having their takeaway or having a pint can ask the landlord to turn the lights off and drink their beer by candlelight."
As to England's hopes of landing their first Grand Slam for 13 years in Paris, Greenwood said: "The key is to have the mental side of the game right. The southern hemisphere sides don't really care who wins the Six Nations but they will sit up and take notice if a side completes the clean sweep, turning over World Cup quarter-finalists like Wales and Ireland.
"Playing at the Stade de France is a mighty challenge for any side, no matter what the current struggles are for the French. They still have threats throughout their side, but if England play with the right tempo, their defence will disintegrate and then England can take their chances."
Earth Hour is on Saturday, 19 March 2016 8:30 p.m. local time. For more information as to how you can get involved click here
