The Big Picture
Minnesota lawmakers are considering a proposal that would dramatically expand liability around historic energy use and emissions. Modeling by the U.S. Chamber of Commerce shows the policy could cost $16.5 billion in 2026, rising to $17.38 billion by 2030—roughly $84.84 billion over five years. For households, that’s about $6,883 in 2026, climbing to $7,243 by 2030 with inflation.
How the Proposal Drives Costs
The bill dramatically and retroactively increases liability on fossil fuel extractors. The Minnesota Pollution Control Agency (MPCA) would determine each company’s liability share, collect the payment through a lump sum or nine annual payments, and place them into a new “Greenhouse Gas Pollution Account.” Those new liability costs would then become direct input costs that would ultimately then be embedded in prices for years to come.
Companies cannot absorb multi-billion-dollar retroactive liabilities—they must pass them onto their customers through increased fuel prices, electricity rates, transportation, construction, heating, and every downstream good and service. The bill ensures that these new costs would ultimately reach Minnesota families and small businesses.
Lump-Sum Option
What It Means for Minnesota Families
Here’s how the annual per household impact shows up in a typical family budget assuming a lump sum payment.
- 2026: $6,883 total
- Electric: $1,610
- Housing: $864
- Transportation: $2,395
- All Other Goods: $2,014
- 2030: $7,243 total
- Electric: $1,696
- Housing: $909
- Transportation: $2,517
- All Other Goods: $2,120
In other words, the policy doesn’t just touch utilities—it ripples into rent and mortgages, commuting and deliveries, and the price of everyday purchases.
Economic Sector Impact
The model also shows which economic sectors would bear the initial hit before costs filter down to families:
- Transportation: $5.75B
- Electric Power: $3.86B
- Industrial: $3.27B
- Residential: $2.07B
- Commercial: $1.56B
The Payment Plan Option
The bill also allows businesses to pay over nine years, with 20% paid in the first year and the remaining 80% over the subsequent 8 years. If they choose this option, businesses’ payments would increase in years two through nine. The inflation adjustment would raise their costs close to $265 million in total, which equals an extra $233 per household.
Why This Hits Minnesota Small Businesses Hard
Minnesota’s own labor market data shows that small businesses are the backbone of the state economy, making up 88.9% of all establishments and employing nearly 18% of the workforce as of early 2025. These firms—most with fewer than 20 employees—are heavily concentrated in sectors like personal services, repair shops, construction, agriculture, and other locally rooted industries that operate on thin margins and cannot easily absorb new compliance or legal risk costs.
Because these businesses drive job growth (small firm employment in the state is up 4.5% since 2019), any policy that triggers significant price increases—like the projected $16.5B in 2026 annual statewide impacts shown in our model—will disproportionately squeeze the very employers Minnesota relies on most. Most small firms cannot spread costs across national markets and typically lack buffers to withstand unpredictable, retroactive liabilities. That means many will face painful choices: reduce staffing, delay expansion, raise prices, or close entirely. Small business closures would have devastating impacts in rural regions, where small business employment reaches 23–30% of all jobs.
Methodology
Emissions valuation.
Our analysis begins by identifying Minnesota’s projected carbon emissions over the analysis window. Those emissions are then valued using the Social Cost of Carbon (SCC)* to produce a total modeled liability for the period. The SCC is used solely to translate emissions into dollars for scenario modeling.
Price pass through and household impacts.
We assume full pass‑through of these mandated costs into prices and rates paid by Minnesota consumers and businesses. Using Minnesota household counts, we converted the annual totals into annual per household impacts and distributed them across four budget categories—Electric, Housing, Transportation, and All Other Goods—to reflect how sector level costs appear in family budgets.
Sector allocation.
Payment is allocated across major sectors—electric power, transportation, industrial, residential, and commercial—in proportion to each sector’s share of Minnesota’s energy related CO₂ emissions. This reflects where emissions originate within the state and how costs propagate through production, distribution, and consumption.
Lump sum option and nine payment schedule option.
The modeled liability is assessed and presented under both the lump sum option as well as the nine annual payments option under the proposal’s installment structure. For the installment structure, the numbers reflect 20% of the sum in year one, and the remaining 80% in the subsequent eight years (with any inflation/indexing, if applicable under the bill, applied consistently year-to‑year within the model).
Presentation.
Because the bill imposes strict, proportional, and potentially joint and several liability across a decades‑long emissions baseline, results are presented as statewide annual impacts (and per household annual impacts), not firm specific projections. The objective is to illustrate how a liability regime of this design would ripple through the entire state economy, affecting households, small businesses, and every sector that depends on energy related inputs.
* Note that the Chamber does not endorse the Social Cost of Carbon as a measurement tool. However, proponents of imposing costs on energy companies as a function of CO2-equivalent emissions frequently rely on the Social Cost of Carbon to quantify those costs, and we believe it is reasonable to assume the Social Cost of Carbon would be employed to calculate damages under this type of legislation.
