Colorado leaders on Thursday unveiled a plan two years in the making to cut heat-trapping air pollution in the state by 90% — a reduction of more than 100 tons a year — before 2050 to improve public health and help contain climate warming.

“This is an issue for all humanity and life on the planet,” and limited international cooperation means individual nations, states and companies must act, Gov. Jared Polis said.

“It’s very much in our interest to do our part,” Polis said in an interview. “We have a climatedriven economy. Hundreds of thousands of jobs in Colorado are climate-dependent. And we want to position Colorado as a climate and green energy leader.”

Burning fossil fuels for 150 years has guaranteed that climate warming will hit harder — megafires, aridity, heat waves, rising sea levels — for at least three more decades, scientists say. But reducing carbon dioxide, methane and other greenhouse gas pollution would minimize future harm. Roughly half the electricity used in Colorado still comes from burning coal, more than in many other states, while gas-powered vehicles and the oil and gas industry add to the atmospheric muck.

The “road map” for state action finalized this week reflects the rise of climate warming and environmental health concerns nationally and worldwide as a top priority. President-elect Joe Biden has promised a $2 trillion investment to hasten a job-generating shift to clean energy and to rejoin the international Paris agreement that President Donald Trump rejected.

Biden also is reorganizing White House staffing to focus on climate warming and has appointed former Sen. John Kerry to coordinate work with other countries. In recent months, China, Japan and the European Union ramped up commitments to cut heat-trapping pollution.

Colorado’s 207-page plan — Polis called it “by far the most ambitious and expansive planning document Colorado has ever produced on climate change” — relies on regulatory agencies to enforce pollution cuts at power plants, oil and gas industry sites, and in buildings. Drivers increasingly would be encouraged to shift from gaspowered to zero-emission vehicles through tax benefits and other incentives.

“There is no single ‘silver bullet’ solution,” the plan says. “Modeling shows that a ‘silver buckshot’ approach of reductions across all the major sectors is needed.”

Lawmakers in 2019 ordered state officials to reduce heattrapping air pollution below a baseline 2005 level, which air quality regulators estimated at 139 million tons a year. The lawmakers mandated cuts by 26% before 2025 to 103 million tons; by 50% before 2030 to 70 million tons; and by 90% before 2050 to 14 million tons. Current overall heat-trapping air pollution hovers around 125 million tons.

Polis has declared Colorado will rely on 100% renewable energy by 2040.

But achieving these targets is expected to require significant new investments, innovations and federal assistance, as well as tougher state policies and standards. State health, energy and transportation officials refining the roadmap emphasized a need to ensure equity, recognizing that climate warming and air pollution often hit low-income and other marginalized communities the hardest.

Key steps over the next decade include:

• Shifting more away from coal in favor of renewable wind and solar electricity.

 

• Reducing methane pollution by the oil and gas industry.

 

• Faster shifting to electric cars, buses and trucks.

 

• Encouraging less driving through smarter land use.

 

• Cleaning up energy used in buildings.

 

• Cutting methane emissions from landfills and wastewater.

The Colorado Chamber of Commerce in November raised concerns, and business leaders on Thursday issued a statement questioning feasibility.

“Economic and environmental progress is best achieved when emissions reduction goals are realistic, achievable and marketdriven,” the chamber said. “While this road map is well-intended, we urge our elected leaders and regulators to fully consider the costs of implementing such measures, particularly under the current economic cireMIssIONs » 4A
