17 percent. That’s how much global carbon emissions have dropped since the coronavirus pandemic sent much of the world into their homes, according to new data from the science journal Nature Climate Change.

But while that dip might appear promising for climate advocates, the glass half-empty perspective is that, even with everyone staying indoors, humans continue to use 83 percent of the fossil fuels they normally would.

Speaking on what this data means in the context of a global climate crisis was Charlie Sennott, who joined Boston Public Radio by phone on Thursday.

"What really struck me about the findings that we’re seeing around this is that behavioral change is not going to be enough,” the GroundTruth Project CEO said. "I don’t think we ever want to forget [that] those individual behavioral changes matter, but what this is going to require is structural change."

Sennott struck an optimistic tone, however, positing that the global shutdown could present an opportunity for world leaders to adapt their energy infrastructure in a substantial way.

"What better moment than right now, when the world is slowed down, to make that structural shift?” he said. "I just wait for the wake-up call when we say, 'we could really fund our infrastructure right now, to make this change.’"
