Carbon Dioxide

Thousands of miles of oil and natural gas pipelines already crisscross the country. Now, many more are being proposed to carry things like hydrogen and carbon dioxide as ways to combat climate change.

“We need to connect the environmental crisis that we’re currently facing with the company’s current and future operations," said a sustainability management professor. "All companies rely on natural assets to some degree, whether it’s clean water, clean air or even disease control."

Other projects are still on the table as advocates, industry groups debate regulatory reform

Proposed projects would add more than 3,000 miles of new carbon pipelines through rural parts of the Midwest. Some emergency officials are concerned about safety, especially after a rupture on a similar pipeline three years ago.

In an effort to reach zero carbon emissions by 2050, the Biden administration is offering more tax credits for carbon capture sequestration and utilization. The program once expected to cost $3.2 billion now could exceed $100 billion.

As Illinois considers ways to achieve its goal of relying entirely on clean energy by 2050, one technology that has courted controversy is carbon capture.

Three companies want to capture carbon dioxide from Midwestern ethanol plants, transport it by pipeline and store it underground. Many in the ethanol industry claim it’s essential to the industry’s survival. Environmentalists and even farmers argue the pipelines are a boon for the industry — not a real solution for climate change.

Agriculture companies are increasingly paying farmers to capture carbon. But some say the newly budding carbon marketplace isn’t enough to fight climate change.

The city gets more trees, and companies are able to offset their carbon use.
