delivered the Opinion of the Court.
T1 In this original proceeding, we review the Title Board's action setting the title and ballot title and submission clause for Proposed Initiative 2015-2016 #68 ("Initiative #63").1 Initiative # 68 seeks to amend article II of the Colorado Constitution to establish a "right to a healthy environment." We conclude that Initiative # 63 contains a single subject-the creation of a right to a healthy environment-and that the title of the initiative clgearly expresses that subject and is not misleading. We therefore affirm the action of the Title Board.
I. Facts and Procedural History
T2 Bruce Mason and Karen Dike are the designated proponents ("Proponents") of Initiative # 68, which would establish a right to a healthy environment in Colorado by adding a new section to article II of the Colorado Constitution. The proposed initiative declares that "[the natural persons of Colorado, including future generations, have an inherent, indefeasible, and inalienable right to a healthy environment," and deems that right "a fundamental right," It requires state and local governments to assign the highest priority to the protection of a healthy environment and provides that if state and local laws conflict, the law that i is more protective of a healthy environment shall govern. Finally, it creates an enforcement mechanism under which an aggrieved person or governmental entity may sue for a failure to abide by or enforce the provisions of the new right,
1 3 - Proponents submitted a final version of Initiative #68 to the Secretary of State on January 8, 2016. On January 20, 2016, the Title Board conducted a hearing and set the title for the initiative. On January 27, 2016, Tracee Bentley and Stan Dempsey ("Petitioners") filed a motion for rehearing, arguing that Initiative #63 contained 'multiple subjects and was misleading in violation of article V, section 1(5.5) of the Colorado Constitution.2
[ 4 The Title Board considered the motion for rehearing at its February 3, 2016, meeting and set the following amended title:
'An amendment to the Colorado consumtion concerning natural persons fundamental right to a healthy environment and, in connectlonatheremth defining "healthy «environment" as safe and sustainable conditions for human life, including healthy air, water, land, and ecological systems; requiring state and local governments to assign the highest priority to protecting a healthy environment; allowing local governments to enact laws that are protective of a healthy environment; stating that such a local law governs over a state law that is less protective of a healthy environment; allowing natural persons and governmental entities to sue to enforce the fundamental right to a healthy environment; and awarding reasonable costs of litigation upon determination that a violation has occurred.
4 5 Petitioners now seek review of the Title Board's actions under section 1-40-107(2), CRS. (2015), alleging that Initiative #63 *631violates the constitutional single-subject requirement. Petitioners also assert that the title contains impermissible catch phrases and is unclear and misleading.
II. Standard of Review
T6 When reviewing a challenge to the Title Board's decision, "we employ all legitimate presumptions in favor of the propriety of the Board's actions." In re Title, Ballot Title & Submission Clause for 2009-2010 #45, 234, P.3d 642, 645 (Colo.2010). Accordingly, only in a clear case will we overturn the Title Board's finding that an initiative is limited to a single subject. In re Title, Ballot Title & Submission Clause for 2011-2012 # 3, 2012 CO 25, ¶ 6, 274 P.3d 562, 565. "We give great deference to the Title Board in the exercise of its drafting authority and will reverse its decision only if the titles are insufficient, unfair, or misleading." In re 2000-2010 # 45, 234 P.3d at 648,
17 The seope of our review is limited. We examine a proposed initiative to determine whether it comports with the single-subject requirement and whether the title as a whole is fair, clear, and accurate, but we refrain from addressing its merits, In re 2011-2012 #3, ¶ 8, 274 P.3d at 565. We do not determine the initiative's efficacy, construction, or future application, as these are matters properly considered if and after the voters approve the initiative, In re 2009-2010 # 45, 234 P.3d at 645.
III 'Analysis
T8 We first consider whether Initiative # 63 consists of a single subject. Because its provisions are directly tied to and implement its central focus, we, conclude that the initiative contains one subject only. We then assess whether the initiative's title is clear. Because, the title uses language that is adequately descriptive without relying on emotionally manipulative catch phrases, we conclude that it is.
A. Initiative # 63 Does Not Violate the Single-Subject Requirement
1. Single-Subject Requirement
T9 In accord with article V, section 1(5.5) of the Colorado Constitution, section 1-40-106.5(1)(a), C.R.S. (2015), requires every constitutional amendment proposed by initiative to be limited to a single subject clearly expressed in the initiative's title We construe the single-subject requirement liberally in order to avoid unduly restricting the initiative process. 'In re 2009-2010 # 45, 234 P.3d at 646.
T10 'An initiative violates the single-subject requirement when it relates to more than one subject and has at least two distinct and separate purposes. In re Title, Ballot Title & Submission Clause 2013-2014 # 129, 2014 CO 53, ¶ 15, 333 P.3d 101, 104. An initiative will satisfy the rule if it "tends to effect or to carry out one general objective or purpose," In re Title, Ballot Title & Submission Clause, & Summary for 1999-2000 # 256, 12 P.3d 246, 253 (Colo.2000) (quoting In re Title, Ballot Title & Submission Clause, & Summary for 1999-2000 #25, 974 P.2d 458, 463 (Colo.1999)), or features several "interrelated" purposes, In re 2009-2010 # 45, 284 P.3d at 646. Implementing provisions that are directly tied to the initiative's central focus are not separate subjects. Id. In short, "the subject matter of an initiative must be necessarily and properly connected rather than disconnected or incongruous." In re 2011-2012 #8, ¶ 9, 274 P.3d at 565 (citation omitted) (internal quotation marks omitted).
11 The single-subject requirement serves to protect against two dangers associated with omnibus initiatives. First, "combining subjects with no necessary or proper connection for the purpose of garnering support for the initiative from various factions-that may have different or even conflicting interests-could lead to the enactment of measures that would fail on their own merits." Id. at ¶11, 274 P.3d at 566; . see also § 1-40-106.5(1)(e)(I), C.R.S. (2015) (explaining that single-subject requirement is intended to forbid combining disconnected subjects in same measure to secure enactment of measures that would not succeed on their own merits), Second, it helps avoid "voter surprise and fraud occasioned by the inadvertent passage of a surreptitious provision 'coiled up in the folds' of-a complex initiative." In re 2011-*6322012 # 3, ¶ 11, 274 P.3d at 566 (quoting In re Title, Ballot Title & Submission Clause for Proposed Initiative 2001-2002 # 43, 46 P.3d 438, 442 (Colo,2002)); see also § 1-40-106,5(1)(e)(II), C.R.S. (2015) (explaining that single-subject requirement is intended to prevent surreptitious measures and apprise voters of the subject of each measure).
2, Application to Initiative # 63
12 Petitioners argue that Initiative # 68 contains multiple separate subjects disconnected from its primary purpose of establishing a right to a healthy environment. They see disconnected subjects: (1) redefining the legal status of local governments; (2) prioritizing and subordinating rights under the Colorado Bill of Rights; (8) modifying preemption law; and (4) creating a cause of action to enforce the right to a healthy environment. We address each of Petitioners contentions in turn.
{13 First, Petitioners argue that Initiative # 63 would change the legal status of local governments under the Colorado Constitution. Proposed subsection (2)(b) of the initiative defines "local government" as "any statutory or home rule county, city and county, city, or town located in the state of Colorado, notwithstanding any provision of article XX or section 16 of article XIV of the Colorado constitution." Article XX grants home rule authority to municipalities, and section 16 of article XIV does so for counties.
{14 While Petitioners' objection arguably overstates the initiative's reach, our inquiry at this juncture avoids interpretation beyond that necessary to determine whether there is a single subject and clear title. See In re Title, Ballot Title & Submission Clause for 2009-2010 #24, 218 P.3d 350, 355 (Colo.2009). In answering the question immediately before us, it suffices for us to observe that an expansive definition of the governmental entities here is necessarily and properly connected to the initiative's purpose, which is to establish and broadly effectuate the right to a healthy environment for all Coloradans. Accord In re Title, Ballot Title & Submission Clause 2018-2014 #90, 2014 CO 63, ¶18, 328 P.3d 155, 161 ("The designation of the government entities that hold the regulatory power authorized under the initiatives is necessarily and properly connected to the central purpose of the measures."). Thus, the initiative's definition of "local government" is not a separate subject.
115 Second, Petitioners contend that Initiative #63 contains more than one subject because in addition to creating a constitutional right to a healthy environment, it requires state and local governments to assign the protection of a healthy environment "the highest priority." Petitioners claim this prioritization conceals the fact that, if enacted, the new section would subordinate existing constitutional rights to the right to a healthy environment,.
{16 But the text of proposed subsection (4) simply provides that state and local governments "shall assign the highest priority to the protection of a healthy environment." It makes no explicit mention of how the right to a healthy environment should be ranked against other constitutional rights.
17 Moreover, even if Petitioners interpretation of proposed subsection (4) is correct, this portion of the initiative does not constitute a separate subject. Petitioners seem to suggest that if protecting a healthy environment is given top priority, all other rights must be subordinated to the right to environmental protection. Accordingly, Petitioners appear to believe the initiative must apprise voters of what rights will be subordinated, and that its failure to do so will cause voters to be surprised by a surreptitious provision "coiled up in the folds" of a complex initiative. But this court has consistent ly required more than the omission of a full accounting of potential effects in order to conclude that an initiative may surprise voters and therefore contains multiple subjects. Compare In re Title, Ballot Title & Submission Clause for 2011-2012 # 45, 2012 CO 26, ¶20, 274 P.3d 576, 581 (concluding that where initiative lacked embedded provisions that would lead to voter surprise or fraud and its plain language described its impact on other legal rights, voters would not be surprised to learn they were voting to alter existing regime in favor of new priorities), *633with In re Title, Ballot Title & Submission Clause for 2009-2010 #91, 235 P.3d 1071, 1079 (Colo.2010) (explaining that voters might be surprised to learn initiative contained second purpose where discovery of that purpose was "revealed only through a close reading of the initiative and an appreciation of its complex text and how its sections interrelate"). Though the initiative does not list in painstaking detail each right or corresponding policy goal that might be subordinated to the protection of a healthy environment should the initiative be enacted, voters will not be surprised to learn that a right assigned the highest priority will take precedence over other objectives. Therefore, we reject Petitioners' implicit subordination argument.
{18 Third, Petitioners assert that Initiative #63 alters Colorado pr eemptlon law. Proposed subsection (5) provides that if a state law or regulation addresses the same topic as a local law, regulation, ordinance, or charter provision adopted pursuant to article II of the Colorado Constitution, the measuré that is more protective of a healthy environment shall govern.
19 We addressed a similar contention in In re Title, Ballot Title & Submission Clause for 2013-2014 #90, 2014 CO 63, 328 P.3d 155. That case concerned Initiatives 2013-2014-# 90 and #98, which proposed adding a new article to the Colorado Constitution that would authorize local governments to enact laws regulating oil and gas development that are more restrictive than state law. Id. at ¶2, 328 P.3d at 158. The initiatives provided that if a local law enacted pursuant to the new article conflicted with state law, the more restrictive and protective law would govern. Id. at App. A, 328 P.3d at 166. Petitioners in that case argued that these provisions changed Colorado preemption doctrine and constituted separate subjects. Lee id. at 116, 328 P.3d at 160. We disagreed, reasoning that:
[T]he central purpose of the initiatives is to grant local governments the authority to enact more restrictive regulations.... Thus, that the Proposed Initiatives declare that more restrictive regulations enacted under the initiatives would govern over conflicting state laws is necessarily and properly connected to the initiatives' central purpose.
Id. at ¶ 19, 328 P.3d at 161.
20 The same logic applies to Initiative #68. The central purpose of Initiative #68 is to establish a right to a healthy environment for all Coloradans. In order to do so, the initiative not only declares that right to exist, but also creates implementation and enforcement provisions, including requiring local governments to assign the highest priority to protecting a healthy environment and allowing more protective local laws to control over less protective state laws. . This latter provision is necessary to ensure that the constitutional right created by, the initiative is accorded the respect it is due and that the will of the voters expressed through the initiative's .adoption is not overridden by state: legislative enactments. Thus, preemption of less protective state laws is necesgarily and properly connected to the. initiative's central purpose and is not a separate subject.
121 Fourth Petitioners claim that creating standing to enforée the right to a healthy environment, and to receive punitive damages, generates an entirely separate right to be added to the Constitution. But the cause of action is not its own right; rather, it safeguards the right Initiative # 68 seeks to create. It is therefore necessarily connected to the initiative's central purpose as a tool for its implementation. See In re Title, Ballot Title & Submission Clause, & Summary 1999-2000 #258(A), 4 P.3d 1094, 1099 (Colo.2000) (rejecting petitioners' contention that "the initiative's creation of a cause of action for enforcement of. its provisions constitutes a separate subject" and explaining that "implementation provisions tied to an initiative's central focus do not violate the single-subject requirement").
"[ 22 In sum, what Petitioners characterize as. "disconnected subjects" are directly tied to and implement the central focus of the initiative. Therefore, we conclude that Initiative #68 satisfies the single-subject requirement. See In re 2000-2010 #45, 234 P.3d at 646 ("Implementing provisions that *634are directly tied to the initiative's central focus are not separate subjects.").
B. Initiative # 63 Does Not Violate the Clear Title Requirement
1. Clear Title Requirement
123 Colorado law also requires that an initiative's single subject be clearly expressed in its title Colo. Const. art. V, § 1(5.5); see also § 1-40-106(8)(b), C.R.S. (2015) ("In setting a title, the title board shall consider the public confusion that might be caused by misleading titles and shall, whenever practicable, avoid titles for which the general understanding of the effect of a 'yes/ for or 'no/against' vote will be unclear."). The Title Board must "set fair, clear, and accurate titles that do not mislead the voters through a material omission or misrepresentation". .. [but] the titles need not spell out every detail of a proposal." In re 1999-2000 # 256, 12 P.3d at 256 (citation omitted). The Title Board has broad discretion in drafting titles, and we give deference to its exercise of that authority,. In re Title, Ballot Title & Submission Clause for 2013-2014 # 89, 2014 CO 66, ¶ 23, 328 P.3d 172, 179.
2. , Application to Initiative # 63
.T 24 Petitioners claim the title set by the Title Board contains impermissible catch phrases-"healthy environment" and "fundamental right"-designed to appeal to voter emotion. Catch phrases are terms that work in favor of a proposal without contributing to voter understanding; they trigger a favorable response to the proposal based not on its content but on its wording. In re 2009-2010 #45, 234 P.3d at 649. Catch phrases are prohibited from inclusion .in titles "to prevent prejudicing voters in favor of the proposed initiative merely by virtue of those words' appeal to emotion and to avoid distracting voters from consideration of the proposed initiative's merits." Id.
$25 Petitioners allege "healthy environment" to be a catch phrase because "healthy" is a term that carries positive connotations and is used regularly in our society. Because they believe that "healthy environment" is not properly defined in the text or title of Initiative #63, they conclude the phrase is "plainly an appeal to voters' emotions." We disagree. The phrase "healthy environment" is descriptive and informative based on the common understanding of the words it contains. Thus, it contributes to a voter's rational comprehension and does not promote impulsive choices based on false assumptions about the initiative's purpose and its effects if enacted. See In re 2013-2014 # 89, ¶ 26, 328 P.3d at 180 ("[Alithough the environment and conservation are common topics of debate, the words used in the initiative do not constitute a catch phrase because they form a descriptive phrase that contributes to voter understanding of the purpose of the initiative.").
Nor is the term "fundamental right" a catch phrase. The title characterizes the right Proponents seek to establish as a "fundamental right" w1thout defining that ph1 ase, and Petitioners assert that the term "adds a gloss of legitimacy to Initiative # 63 that is unrelated to its substance." But spec-1fy1ng 'that the new right is a "fanddmental right" merély alerts voters phat it is to be given primary importance. As this message is consistent with the initiative's prioritization of the right to a healthy environment, the term "fundamental right" is descriptive of the proposal and contributes to voter understanding. Petitioners have failed to "prove that, rather than describing the initiative, the phrase provokes emotion such that it imper-misgibly distracts voters from consideration of the initiative's merits." In re 2009-2010 # 45, 234 P.3d at 650.
l; [27 The terms "healthy environment" and "fundamental right" accurately describe the right that Initiative # 63 seeks to create and do not improperly distract voters or, appeal to their emotlons , We therefore 'conclude that neither is an 1mperrmsmble catch ph1 ase.
128 Petitioners also claim that Initiative #68 violates the clear title requirement because the terms "highest priority" and "protective of a healthy environment" are vague, misleading, and lack measurable 'standards. Along the same lines, they assert that the title lacks sufficient reference to the *635proposed initiative's enforeement provisions. But again, a title need not spell out every detail of a proposal, In re 1999-2000 # 256, 12 P3d at 256. Though the title lacks a detailed description of the specific areas in which the environment should be made the highest priority (for example, the highest legislative priority or the highest budgetary priority), this omission does not make the title unclear, Similarly, the title is not required to list every type of action that would protect or damage a healthy environment; nor is it required to list every right over which the proposed right to a healthy environment would take precedence. The title as set by the Title Board adequately informs voters of the key elements 'and purpose of Initiative # 68. | _
1l29 Addltlonally, the tltle suffi c1ent1y advises voters that if enacted, the initiative will create a cause of action to sue for enforcement. The omission of details regarding the remedies available does not obscure the intent of the measure. Moreover, this court's function is not to write the best possible titles; we reverse the Board's chosen language only if it is "clearly inaccurate or misleading." Id. As that is not the case here, we reject Petitioners' arguments.
30 We conclude that the title accurately summarizes the content of Initiative #63 and does not contain any material omission or misrepresentation, nor does it contain an impermissible catch phrase. The title alerts voters to the key features contained in the initiative and allows them to make an informed choice on the- merits of the proposal. It therefore satisfies the clear title requirement, and we defer to the Title Board's decision to approve the title.
IV. Conclusion
4 31 We hold that Initiative # 68 contains a single subject-the creation of a right to a healthy environment, We also hold that because the title set by the Title Board is fair, clear, accurate, and does not mislead voters, it does not violate the clear title requirement. Accordingly, we affirm the actions of the Title Board.
