Beto O'Rourke released his official climate change plan last week, outlining a $5 trillion dollar plan to improve infrastructure and reach net-zero U.S. emissions by 2050 — but he amended his plans to include new provisions Iowans asked for.

The four new provisions, announced Wednesday, include topics Iowa farmers and Iowans affected by floods addressed with the 2020 presidential candidate during the Texans' recent visit to the state.

For example, he added a proposal to expand federal crop insurance to cover stored grains after he visited flooded Pacific Junction, his campaign staff said.

“The policy prescriptions are important — the facts and the science behind it — but there’s nothing more powerful than meeting the people who are experiencing it," the Democrat told the Des Moines Register on Sunday after a town hall event in Red Oak. "Seeing with my own eyes what they are trying to live through right now ... add the urgency that's necessary to get this done."

The proposals include:

Expanding federal crop insurance to cover stored grains and investing in flood infrastructure

Streamlining an existing application process to enable family farms to profit from the transition to wind energy

Investing in land-grant universities and new programs to develop agriculture technology

Creating performance incentives to encourage, but not require, carbon farming practices such as no- or reduced-till agriculture, the use of cover crops and carbon-capturing crop rotation

Before Beto released his new Iowa-specific proposals, he also hosted a roundtable discussion with renewable energy business leaders and environmental activists in Des Moines Monday.

O'Rourke talked about his plans at both his Charles City and Fayette house parties on Tuesday, outlining why he believes his proposal will help Iowans.

His campaign says his entire $5 trillion plan would be "directly leveraged by a fully paid-for $1.5 trillion investment," and funded through raising taxes on wealthy individuals and corporations.

He also recently signed the "no fossil fuel money" pledge and returned donations from fossil fuel executives after being repeatedly asked about the donations in Iowa and elsewhere.

On the campaign trail, O'Rourke repeatedly emphasized the urgency of acting on climate change to mitigate natural disasters, like Iowa's flooding, Hurricane Harvey in Texas and California wildfires last year.

He said the nation should rely on the know-how and innovation of farmers to disturb less of the carbon in the soil and offer them a “performance-based” measure, “which they will achieve if we will give them the chance to do this, the chance to lead as they have in so many instances in our past.”

“This is the last best hope of earth, literally,” he said.
