Our Children’s Trust has represented and supported young people in Colorado since 2011, including the climate lawsuit Martinez v. Colorado Oil & Gas Conservation Commission and - most recently - a petition for rulemaking submitted to the Colorado Oil and Gas Conservation Commission (COGCC) in November 2019 and the COGCC’s ongoing rulemaking to implement the mandates of Senate Bill 19-181.

The youth petitioners are represented by Nate Bellinger with Our Children’s Trust.

Current Status:

In November 2020, the COGCC finalized its rules that are intended to protect public health, safety, welfare, the environment, and wildlife resources from oil and gas development. In his closing remarks Chair Robbins acknowledged the contributions of the Colorado youth OCT represented in the rulemaking: "I as Chair and the Commission as a whole thanks the Our Children’s Trust petitioners for their sincere thoughtful and passionate petition, their pleadings and their presentations in this rulemaking. . . . We hope you will stay engaged and work with us as we implement these rules to protect public health, safety, welfare, the environment, and wildlife resources."

While the COGCC's final rules did include some of the requests made by Earth Guardians and Our Children's Trust to better quantify GHG emissions attributable to Colorado's oil and gas sector, unfortunately, the final rules fail to require adequate reductions in GHG emissions from the oil and gas industry. Our Children's Trust is continuing to work with Colorado youth to ensure that the state fulfills its legal obligations to protect their health and the environment and reduces its GHG emissions to levels consistent with the best available science.

Eight young Colorado activists, all members of the Boulder-based climate organization Earth Guardians and including Xiuhtezcatl Martinez, rallied at the State Capitol and then marched to the COGCC office to hand-deliver a petition for rulemaking. The petition called for the COGCC to promulgate rules to suspend the issuance of permits that allow hydraulic fracturing until it can be done without adversely impacting human health and safety and without impairing Colorado’s atmospheric resource and climate system, water, soil, wildlife, and other biological resources.

January 14, 2019: Colorado Supreme Court Ruling

The Colorado Supreme Court reversed the Colorado Court of Appeals decision and found that the COGCC cannot condition oil and gas development on protecting public health, safety, and welfare and the environment.

Justice Gabriel, in a unanimous decision, acknowledged the civic engagement and concerns of the youth plaintiffs’ and even found that their interpretation of the Act, which would have required the COGCC to prioritize public health over oil and gas development, was reasonable. However, the Court ultimately rejected plaintiffs’ reasonable interpretation of the Act, determined that the Act was ambiguous, and held that the COGCC did not have authority to promulgate a rule protecting public health if it precluded new oil and gas development.

Friday, November 24

January 24, 2019: Extraordinary Motion

Attorneys for the youth plaintiffs filed an extraordinary motion with the Colorado Supreme Court asking the Court to vacate its January 14th decision and the 2017 Court of Appeals decision based upon the misconduct of a judge who was on the Court of Appeals panel. Declarations were also filed by lead plaintiff Xiuhtezcatl Martinez and his attorney Julia Olson.

Friday, November 24

January 28, 2019: Extraordinary Motion Denied by Court

In a one sentence decision, the Colorado Supreme Court denied the youth plaintiffs’ January 24 motion.

Friday, November 24

February-April 2019: Coloradans Respond to Supreme Court loss

Disappointed by the Supreme Court’s decision and the ongoing dangers of Colorado’s oil and gas development, youth plaintiffs and supporters from across Colorado responded with a concerted effort to amend Colorado’s Oil and Gas Conservation Act, the law at the center of the Martinez case, to make clear that protecting public health and the environment is the COGCC’s primary obligation, not promoting oil and gas development.

Friday, November 24

April 16, 2019: Governor Signs SB 19-181

With a youth plaintiff in attendance, Colorado Governor Jared Polis signed SB 19-181, a bill “concerning additional welfare protections regarding the conduct of oil and gas operations,” making important amendments to the Colorado Oil and Gas Conservation Act (Act).

Among other important changes to the Act, SB 19-181 made clear that the COGCC must protect public health and the environment from oil and gas development; clarifies that the nonproduction of oil and gas does not constitute “waste;” eliminates the requirement that protections for public health and the environment take into consideration cost-effectiveness and technical feasibility; and gives more control over oil and gas operations to local governments. These amendments reinforced and vindicated the legal arguments made by the youth plaintiffs in Martinez et al., v. Colorado Oil and Gas Conservation Commission.

Friday, November 24

May 30, 2020: Governor Sign HB 19-1261

Governor Jared Polis signed HB 19-1261 declaring that “climate change adversely affects Colorado’s economy, air quality and public health, ecosystems, natural resources, and quality of life” and setting a goal of eliminating statewide greenhouse gas (GHG) pollution by mid-century.

Friday, November 24

November 8, 2019: Petition for Rulemaking Filed

To ensure that SB 19-181 is properly implemented, over 60 Colorado youth filed a petition for rulemaking calling on the COGCC to enact new, science-based, rules that are consistent with protecting Coloradans’ public health, safety, and welfare from oil and gas development and climate change.

Friday, November 24

May 22 - August 14, 2020: COGCC Rulemaking Filings

Our Children’s Trust, on behalf of the 65 youth petitioners that filed the November 2019 petition for rulemaking, and Earth Guardians submitted a series of comments, expert testimony, proposed rule changes, and legal arguments to the COGCC regarding its ongoing rulemaking.

The Commission’s rulemaking is intended to implement the mandates of SB 19-181 and protect public health and the environment from dangerous oil and gas operations. However, the Commission’s draft rules (and ongoing permitting of dangerous oil and gas operations) still do not adequately align with its new mandate to prioritize protections for public health and the environment and to address the cumulative impacts of oil and gas operations on the climate crisis.

Friday, November 24

August 24-September 28, 2020: COGCC Hearings

The COGCC heard presentations from dozens of parties on proposed changes to their rules that are intended to protect public health and the environment from Colorado’s oil and gas development.

Our Children’s Trust Senior Staff Attorney Nate Bellinger presented three separate times pressing the COGCC to adopt rules that address the oil and gas industry’s contributions to the climate crisis and are consistent with the state’s GHG reduction targets.

As part of the hearings, the Colorado Oil and Gas Conservation Commissioners deliberated proposed rule changes and directed staff to make certain changes to the rules.
