In the three years since most of the world's nations signed on to the Paris climate agreement, major oil and gas companies have poured more than $100 billion into their fossil-fuel infrastructure. That's more than 10 times the amount the same companies have spent on low-carbon investments, despite lip service toward that area, according to a new report.The five biggest—ExxonMobil, Royal Dutch Shell, Chevron, BP and Total—will collectively spend $115 billion on capital investments this year, according to the report. Just 3 percent of that spending will go to low-carbon investments, like hydrogen batteries or electric-car charging stations.
