Ferries and factory retrofits gave most of the projected cuts for 15% of the money

For each type of fiscal year 2025 Climate Commitment Act project with an emission estimate, its share of spending and its share of projected lifetime emission cuts. Types run from lowest to highest cost per ton.

Point chart by project type. Industrial and clean-fuel: 2% of spending, 14% of tons. Ferry hybrid conversion: 13% of spending, 49% of tons. Transit: 18% of spending, 12% of tons. Home appliance rebates: 11% and 7%. EV charging: 17% of spending, 4% of tons. Walking and biking: 6% of spending, 0.2% of tons. Home weatherization: 6% of spending, 0.1% of tons.

Tap, hover over or focus a point to see its values.

Two cheap types, ferry hybrid conversions and industrial retrofits, got 15% of the money and 63% of the projected cuts. EV charging, building upgrades, walking and biking, and weatherization together got 39% of the money and 7% of the cuts.

What this chart asks

Which types of climate projects got the money, and which delivered the emission cuts?

Why it is shown this way

  • Paired points per type compare the share of money with the share of tons on one linear axis; a type whose spending point sits far above its tons point bought cuts at a high cost per ton.
  • A cost-per-ton bar chart was not used because values range from $61 to $54,100, which a linear axis cannot show readably.
  • Types are ordered from lowest to highest pooled cost per ton.

Washington Climate Commitment Act spending: cost per ton of emission cuts, fiscal year 2025

  1. Washington Department of Ecology, Climate Commitment Act Investments Report: Fiscal Year 2025 (Pub. 25-14-107), updated March 2026 Project-level fiscal year 2025 spending and projected lifetime emission cuts (Appendix B); biennium totals and cost-effectiveness (pp. 13, 40-45).

    Reliability: Government. Has a stake in this finding. Ecology runs the CCA and compiles this report from figures each agency reports; it revised the report in March 2026 after errors in Commerce data. The agency benefits when CCA spending appears effective.

  2. Washington Department of Ecology, transmittal letter to legislators on the updated CCA investment report, March 19, 2026 Original and revised biennium totals (8,635,900 and 1,201,286 tons; $40 and $322 per ton) and the 61 corrected Commerce projects.

    Reliability: Government. Speaks against its own interest. Ecology’s own account of its correction, which lowers the program’s reported results.

  3. Washington Department of Commerce, "Commerce submits corrected greenhouse gas emissions data for state climate report," January 6, 2026 Commerce’s correction of eight rebate projects (7.5 million to 78,000 tons) and its own total of nearly 308,000 tons.

    Reliability: Government. Speaks against its own interest. Commerce made the data-entry error and announced the correction.

Limitations

  • Project types are FactHub groupings of appropriation titles, not Ecology categories.
  • Emission cuts are agency projections over each project's lifetime, not measured.
  • About 71,000 tons that appear to be counted twice sit almost entirely in the ferry type.
  • Several types (walking and biking, habitat, Tribal consultation) mainly serve goals other than cutting emissions.
