Google (GOOG) CEO Sundar Pichai also weighed in.

Meanwhile, over on Facebook (FB, Tech30), CEO Mark Zuckerberg shared his own chagrin.
"Withdrawing from the Paris climate agreement is bad for the environment, bad for the economy, and it puts our children's future at risk," Zuckerberg said.

In recent months, hundreds of companies have lobbied the Trump administration to remain in the agreement. Apple (AAPL, Tech30), Starbucks (SBUX), Gap (GPS), Nike (NKE), Adidas (ADDDF), L'Oreal (LRLCF) and Monsanto (MON) all voiced their support for the Paris deal.

Even oil companies like ExxonMobil (XOM) and Chevron (CVX) gave their backing. Exxon CEO Darren Woods wrote Trump a personal letter earlier this month asking him to remain in the pact, saying it ensures the U.S. is "well positioned to compete."
