When an individual questioned what actions Musk would take if Trump does pull out of the Paris Agreement, which the president is reportedly on the verge of doing, the CEO said he would pull out of his own agreement to advise President Trump.
Trump has said the accord would cost the USA economy trillions of dollars without tangible benefit.
The only Canadian leader who understood the importance of Canada moving in sync with the USA on carbon pricing - lest we deliberately undermine our economy - was former Conservative prime minister Stephen Harper.
"The Paris Agreement is proof that with shared political will and mutual trust, multilateralism can succeed in building fair and effective solutions to the most critical global problems of our time".
Those who want to see the USA stay in the accord or renegotiate it include Secretary of State Rex Tillerson, senior adviser Jared Kushner, Energy Secretary Rick Perry, economic adviser Gary Cohn and national security adviser H.R. McMaster.
A US exit won't sink the Paris agreement, but it could hurt the efforts of developing countries counting on aid to meet their targets.
"The EU and China are joining forces to forge ahead on the implementation of the Paris agreement and accelerate the global transition to clean energy", said EU climate commissioner Miguel Arias Cañete.More news: Warburton keen for action as Lions begin tough quest

"That's the biggest irony of Donald Trump's hypocrisy", Blumenthal said.
Trump claimed before taking office that climate change was a "hoax" created by the Chinese to hurt the USA economy, an assertion that stands in defiance of broad scientific consensus.
"Climate change is not a fairy tale". At the summit, leaders expressed frustration about Trump's stance on the landmark agreement and urged him to remain in it.
According to John Sterman, a professor at the MIT Sloan School of Management and senior advisor at ClimateInteractive, leaving the Paris Agreement would create an uncertainty in the economy over the future of both fossil fuels and renewable energy resources.
Word of Trump's expected decision came a day after the president met with Pruitt.
But current trends do not guarantee that the USA will meet its Paris commitment to reduce domestic greenhouse gas emissions by 26 to 28 percent below 2005 levels by the year 2025 - absent a global climate accord.
He dropped the idea when Obama's carbon pricing proposal subsequently died in Congress, because he understood that going ahead without the USA would amount to Canada putting a bullet in its own economy as it tried to recover from the 2008 global recession.
"Withdrawal from the climate change agreement would be a job killer", Blumenthal said. Extreme weather in many places has increased. The Mercer and Hudson generating stations will close on Thursday, as cheap natural gas continues to force coal off of the grid in states across the country. Failing to create steady leadership in this area makes it more hard for USA entrepreneurs and businesses to invest in these areas, resulting in an accumulation of lost economic opportunities.
