and a carbon tax as means to reduce emissions, saying that the two proposals are "perfectly compatible" with each other. Schatz believes that climate change is a threat and has supported clean energy initiatives. In 2013, he wrote an op-ed promoting subsidies for wind turbines. He has advocated for 50% clean and carbon-free electricity by 2030. He opposed the Keystone Pipeline. Along with Martin Heinrich and Sheldon Whitehouse, Schatz is one of the "Three Climateers" of the Senate, driving and negotiating legislation to address climate change, culminating in the Inflation Reduction Act of 2022. Foreign policy Schatz criticized China's island-building activities, saying that "China’s outsized claim to the entire South China Sea has no basis in international law." In October 2017, Schatz condemned the genocide of the Rohingya Muslim minority in Myanmar and called for a stronger response to the crisis. Schatz spearheaded a nonbinding resolution in July 2018 "warning President Trump not to let the Russian government question diplomats and other officials".

He expressed disappointment when both the Democrat-proposed Feinstein Amendment (making the sale of firearms to individuals on the terrorist watchlist illegal) and the Republican-supported background check changes and gun sale alert system did not pass the Senate. He said: More than 90% of Americans demand we take action on gun violence, but again Senate Republicans refuse to act. It's unacceptable.

After one of the most horrific mass shootings in our history, we saw people across the country courageously stand up against gun violence and hatred. When will Republicans in Congress finally do the same? In response to the 2017 Las Vegas shooting, Schatz said, "We
