Delaney in Iowa

To stave off the effects of climate change, he’d try to encourage the development of “negative emission technology,” machines that take carbon out of the air. Delaney said he’d take $5 billion in annual tax incentives from the fossil fuel industry and “create a market” for those new technologies.

Under his plan, the federal government would buy carbon from the lowest bidder, encouraging companies to build carbon-capturing technology so they can sell to the government.

When it comes to flood prevention, he said improvements are “situational” but could include building higher levees or using additional stormwater pumping stations. Delaney will arrive in Iowa on Saturday, two weeks after flooding devastated farms and communities along the Missouri River.
