Abstract Co-creation in environmental decision-making represents a shift from traditional, top-down approaches toward collaborative processes that actively involve diverse stakeholders in shaping sustainability initiatives. By engaging citizens, communities, and experts from the earliest stages, co-creation integrates scientific knowledge with local, experiential, and cultural insights to develop more context-sensitive and equitable solutions. Moving beyond participation as consultation, co-creation emphasizes shared ownership, iterative learning, and the redistribution of power in decision-making processes. It contributes not only to improved project outcomes but also to strengthened trust, institutional legitimacy, and the potential for transformative change. The document also situates co-creation within a broader ecosystem of related approaches, including co-design, co-production, and co-governance, offering a comprehensive guide for practitioners, policymakers, and educators seeking to advance inclusive and sustainable environmental governance.

  1. Introduction

Co-creation in environmental decision-making is a collaborative process that brings together diverse stakeholders - including citizens, communities, practitioners, and experts - at the earliest stages of an initiative to jointly shape its direction. Rather than treating people as passive recipients of decisions, co-creation positions them as active contributors to defining problems, generating knowledge, and developing solutions.

This early and continuous engagement helps build shared understanding, mutual trust, and collective ownership. By integrating scientific expertise with local knowledge, cultural values, and lived experiences, co-creation enables more context-sensitive, equitable, and sustainable outcomes.

Figure 1: Co-creation builds sustainable environmental decisions

Importantly, co-creation moves beyond purely technical or top-down approaches. It recognizes that environmental challenges - such as urban greening, ecosystem restoration, and climate adaptation - are not only scientific or managerial problems, but also social and political ones. As such, effective responses require inclusive processes that reflect the priorities, trade-offs, and realities of the communities they affect.

Environmental decision-making has traditionally been driven by expert-led, top-down models that prioritize technical efficiency and regulatory compliance. While such approaches can deliver rapid results, they often overlook local knowledge, exclude affected communities, and struggle to build long-term legitimacy.

Co-creation represents a fundamental shift from this model. It redistributes power, integrates multiple forms of knowledge, and emphasizes collaboration, equity, and shared ownership of both processes and outcomes.

  2. Key Aspects

Inclusive and Meaningful Participation

Co-creation begins with the deliberate inclusion of a wide range of stakeholders - including citizens, community groups, NGOs, and experts - from the earliest stages of a project. Particular attention is given to marginalized or underrepresented groups, whose voices are often excluded in conventional processes. However, inclusion alone is not sufficient. The quality of participation matters. Meaningful co-creation requires that participants have real opportunities to influence decisions, rather than simply being consulted after key choices have already been made.

BOX: Conceptual anchor The work of Sherry Arnstein highlights that participation exists on a spectrum, from tokenism to genuine citizen power. Co-creation aligns with the upper levels of this spectrum - partnership, delegated power, and citizen control - where decision-making authority is shared. Figure 2: Ladder of Citizen's Participation Sherry Arnstein's Ladder of Citizen Participation (1969) is a framework that categorizes levels of public involvement in decision-making, ranging from non-participation (manipulation, therapy) to degrees of tokenism (informing, consultation, placation) and ultimately to genuine citizen power (partnership, delegated power, citizen control). It highlights how participation is not just about inclusion, but about the redistribution of power, emphasizing that meaningful engagement requires citizens to have real influence over outcomes rather than merely being consulted.

Shared Knowledge and "Hybrid" Understanding	A defining feature of co-creation is the integration of different types of knowledge. Scientific and technical expertise is combined with local, experiential, and cultural knowledge to create a more holistic understanding of environmental challenges. Tools such as citizen science, participatory mapping, and community-based monitoring enable this blending of perspectives. The result is not just more data, but better insight - grounded in both empirical evidence and lived reality.
Joint Ownership and Legitimacy	When stakeholders are actively involved in shaping decisions, they are more likely to develop a sense of ownership over both the process and its outcomes. This strengthens legitimacy and increases the likelihood of long-term success. In environmental contexts, where implementation often depends on behavioral change or local stewardship, this sense of ownership is critical. Projects such as urban greening or ecosystem restoration are more sustainable when communities see them as "their" initiatives rather than externally imposed interventions.
Iterative and Adaptive Processes	Co-creation is rarely linear. It involves continuous cycles of dialogue, feedback, and adjustment. Conflicts and disagreements are not viewed as obstacles, but as opportunities to refine understanding and negotiate better solutions. This adaptive nature makes co-creation particularly suited to complex environmental challenges, where uncertainty is high and conditions may change over time.

Co-Creation Across Project Phases

Co-creation typically unfolds across several interconnected phases (also see Annex on Related Terms):

Figure 3: The Four Phases of Co-Creation

Table 3 outlines the four key phases of the co-creation process, highlighting how stakeholders collaborate from problem identification to evaluation and learning. Each phase involves distinct activities, participants, and expected outcomes, illustrating the iterative and participatory nature of co-creation. Together, these phases demonstrate how inclusive engagement can strengthen planning, implementation, and long-term sustainability of projects and policies.

Table 3: Co-creation Phases and Actions

Phase	Description	Key Activities	Main Participants	Expected Outputs
Co-Identify	Defining and understanding the problem collaboratively with all relevant stakeholders.	Stakeholder consultations Problem mapping Needs assessments Shared priority setting	Community members, local authorities, researchers, NGOs, businesses	Shared understanding of issues, agreed priorities, and clearly defined objectives
Co-Design	Generating ideas, scenarios, and solution pathways together through participatory planning.	Workshops and brainstorming sessions Scenario development Strategy formulation Prototype or pilot design	Planners, experts, citizens, policy makers, technical specialists	Action plans, project designs, policy options, and collaborative strategies
Co-Implement	Jointly carrying out interventions, projects, and actions in partnership with stakeholders.	Project execution Resource sharing Capacity building Community participation	Government agencies, NGOs, communities, private sector actors, volunteers	Implemented projects, strengthened partnerships, and operational solutions
Co-Evaluate	Assessing outcomes collectively, including defining what �gsuccess�h means for all participants.	Monitoring and evaluation Feedback collection Impact assessment Lessons learned workshops	Stakeholders, evaluators, beneficiaries, researchers, policy makers	Evaluation reports, shared learning, improved practices, and future recommendations

Focus on Co-Benefits and Equity

Co-creation explicitly seeks to distribute benefits fairly across different groups, particularly those who are most vulnerable to environmental risks. It encourages the identification of "co-benefits" - solutions that address multiple objectives simultaneously, such as climate resilience, social inclusion, and public health.

By foregrounding equity, co-creation helps ensure that sustainability transitions do not reinforce existing inequalities, but instead contribute to more just and inclusive outcomes.

  3. Practical "Enablers" and Barriers

While co-creation offers significant benefits, it does not happen automatically. It requires deliberate design, facilitation, and resource commitment. Understanding both the enabling conditions and common barriers helps practitioners move from intention to effective implementation.

Key Enablers of Co-Creation

Some of key enablers of co-creation are listed below. These are not just supportive elements, but often preconditions for meaningful co-creation.

Figure 4: Key Enablers of Co-Creation

Table 4 highlights several enabling conditions necessary for meaningful and effective co-creation. Beyond participation alone, successful co-creation depends on supportive institutional environments, inclusive communication, adequate resources, and trusted facilitation processes that allow diverse stakeholders to engage openly and equitably. Together, these factors help build trust, strengthen collaboration, and ensure that co-creation processes lead to more legitimate and sustainable outcomes.

Table 4: Enabling Co-Creation

Enablers	Description
Neutral and Skilled Facilitation	Effective co-creation depends on facilitation that can balance power dynamics, manage conflict, and ensure that all voices are heard. Independent or trusted third-party facilitators are often critical, especially in contexts with strong institutional or political hierarchies.
Safe and Inclusive Spaces	Participants must feel safe, respected, and valued in order to contribute openly. This includes both physical and digital environments, as well as culturally sensitive processes that encourage participation from marginalized groups.
Adequate Resource Allocation	Co-creation requires time, funding, and logistical support. Providing stipends, transport, childcare, or translation services can make participation possible for those who would otherwise be excluded.
Accessible Communication	Technical information must be translated into clear, accessible formats. Visual tools, storytelling, and participatory methods can help bridge the gap between expert knowledge and community understanding.
Institutional Openness	Organizations must be willing to share control and adapt their decision-making processes. Without genuine institutional commitment, co-creation risks becoming superficial.

Common Barriers to Co-Creation

Some of the challenges frequently encountered in co-creation processes are listed below. If unaddressed, these can undermine the effectiveness of the process (Also see Section 6 on "Challenges and Mitigation"):

Table 5 identifies some of the major barriers that can limit the effectiveness of co-creation processes. While co-creation aims to promote inclusive participation and shared decision-making, challenges such as unequal power relations, limited communication, tokenistic engagement, and participation fatigue can undermine meaningful collaboration. Recognizing and addressing these barriers is essential for building trust, sustaining stakeholder engagement, and achieving equitable and impactful outcomes.

Table 5: Barriers to Co-Creation

Barriers	Description
Time and Process Intensity	Co-creation takes longer than conventional decision-making due to the need for dialogue, trust-building, and iteration. This can conflict with political or funding timelines.
Tokenism	Stakeholders may be invited to participate without being given real influence. This often leads to frustration and erodes trust, particularly among communities that have experienced repeated "consultation without impact."
Power Imbalances	Differences in knowledge, authority, or social status can lead to domination by certain actors, marginalizing others despite formal inclusion.
Knowledge and Communication Gaps	Complex technical information can be difficult for non-experts to engage with, while local knowledge may be undervalued or overlooked by professionals.
Participation Fatigue	Communities, especially marginalized ones, may be repeatedly asked for input without seeing tangible outcomes, leading to disengagement.

Bridging Enablers and Barriers

A useful way to think about co-creation is that each barrier to co-creation has a corresponding enabling strategy to overcome that barrier. For example:

• Power imbalances ➔ addressed through facilitation and ground rules
• Tokenism ➔ addressed through shared decision-making mechanisms
• Knowledge gaps ➔ addressed through accessible communication tools
• Participation fatigue ➔ addressed through transparency and feedback loops

This reinforces the notion that co-creation is not just a philosophy, but a designed process requiring continuous adjustment.

Table 6: Enablers and Barriers of Co-creation

Enablers:	Barriers:
Neutral Facilitation: Using third-party moderators to balance power dynamics. Safe Spaces: Creating environments (physical or digital) where marginalized groups feel safe to speak. Resource Allocation: Providing stipends or childcare to ensure low-income residents can participate.	Time Intensity: Co-creation takes longer than top-down decision-making. Tokenism: Inviting “representatives” who don't actually speak for the community. Knowledge Gaps: The struggle to translate complex technical data into “layperson” terms.

  4. Examples in Practice

Co-creation is increasingly being applied across a wide range of environmental contexts. The following examples illustrate how its principles translate into practice, highlighting different entry points, tools, and outcomes.

Case Study Card 1: Urban Greening and Public Space Planning In many cities, co-creation is used to design and manage green spaces that reflect local needs and values. Residents are engaged through participatory mapping, community workshops, and digital tools to identify how spaces are used, what they lack, and what they could become. These insights are then combined with ecological and spatial data to guide planning decisions.

Typical Co-creation Elements Participatory GIS mapping of community preferences Co-design workshops for park layouts and functions Community stewardship programmes for maintenance

Value Added: Green spaces become more inclusive, better used, and more aligned with local cultural and social practices.

Case Study Card 2: Ecosystem Restoration and Nature-Based Solutions Co-creation plays a key role in ecosystem restoration projects, particularly where local livelihoods and environmental goals intersect. For example, in river or watershed restoration, communities contribute knowledge about seasonal flows, traditional practices, and access needs. This ensures that restoration efforts are both ecologically sound and socially acceptable.

Typical Co-creation Elements Joint problem identification (e.g. flooding, erosion) Community input into design and access considerations Shared monitoring of ecological outcomes

Value Added: Restoration projects are more sustainable because they integrate ecological science with local realities and encourage long-term community stewardship.

Case Study Card 3: Climate Adaptation Planning Climate adaptation requires decisions under uncertainty, making co-creation particularly valuable. Cities and regions increasingly involve stakeholders in developing adaptation strategies, such as heat action plans or flood resilience measures. Scenario-building exercises and participatory risk assessments help stakeholders understand trade-offs and co-develop solutions.

Typical Co-creation Elements Co-development of climate risk scenarios Participatory vulnerability assessments Joint prioritization of adaptation measures

Value Added: Adaptation strategies are more robust, context-specific, and socially accepted, increasing their effectiveness over time.

Case Study Card 4: Sustainable Resource Management Policies Co-creation is also used in designing policies related to energy, water, and resource use. For instance, developing sustainable heating systems or water management plans often involves multiple stakeholders with competing interests. Co-creation processes help build shared visions and negotiate trade-offs.
Typical Co-creation Elements Multi-stakeholder dialogues and deliberation platforms Co-design of policy instruments and incentives Feedback loops during policy implementation	Value Added: Policies gain legitimacy and are more likely to be implemented effectively because stakeholders have been involved in shaping them.

Cross-Cutting Insight

Across all these examples, a common pattern emerges:

• Co-creation starts with shared problem definition
• It relies on blending knowledge systems
• It builds ownership and trust
• It leads to more durable and equitable outcomes

  5. Why Co-creation Matters

Co-creation is not simply a participatory method; it represents a fundamental shift in how environmental decisions are understood, made, and implemented. Its importance lies in its ability to address the complexity, uncertainty, and contested nature of sustainability challenges.

Improved and More Context-Sensitive Outcomes	Environmental interventions designed through co-creation are more likely to reflect local realities, needs, and constraints. By integrating diverse knowledge systems, they move beyond "one-size-fits-all" solutions and instead produce context-specific responses that are both practical and effective.
Addressing Power and Inequality	Environmental decision-making is inherently political, often shaped by unequal access to resources, knowledge, and influence. Co-creation creates spaces where these imbalances can be acknowledged and, to some extent, corrected by redistributing voice and agency. This is particularly important in sustainability transitions, where the costs and benefits of change are rarely evenly distributed.
Building Trust and Institutional Legitimacy	Trust is a critical but often overlooked component of environmental governance. Co-creation fosters transparency and accountability by involving stakeholders directly in decision-making processes. Over time, this can strengthen relationships between communities, governments, and other actors, enhancing the legitimacy of both decisions and institutions.
Enabling Transformative Change	Many environmental challenges require not incremental adjustments, but systemic transformation. Co-creation supports such change by: Encouraging new ways of thinking and problem-framing Building shared visions of the future Enabling collective action across sectors and scales In this sense, co-creation is not just about better projects, but about reshaping governance systems themselves.

  6. Challenges and Mitigations

Co-creation is inherently complex because it involves sharing power, navigating conflicting interests, and working across different knowledge systems. Rather than viewing these challenges as failures, they should be anticipated and managed through deliberate design and facilitation.

Table 7: Challenges and Mitigation Strategies for Co-creation

Common Challenge	Description	Mitigation Strategy
Power Imbalances	Authorities, experts, or dominant groups may shape discussions and outcomes, limiting meaningful participation.	Use neutral facilitation, establish clear ground rules, and actively validate lived experience alongside technical expertise.
Tokenism	Participation is superficial, with little real influence on decisions.	Ensure transparency in how input is used; embed stakeholder roles in decision-making structures, not just consultation processes.
Consultation Fatigue	Communities are repeatedly asked for input without seeing results or impact.	“Close the loop” by communicating outcomes clearly: what was heard, what changed, and why.
Conflicting Values and Interests	Divergent priorities (e.g. economic development vs environmental protection) can create deadlock.	Use early-stage value mapping and scenario-building to identify co-benefits and negotiate trade-offs.
Time and Resource Constraints	Co-creation processes require sustained engagement, which may not align with funding or political cycles.	Build realistic timelines, allocate dedicated resources, and treat relationship-building as a core project component.
Knowledge Gaps	Technical complexity and differing knowledge systems hinder mutual understanding.	Use visual tools, methods, and knowledge brokers to translate across domains.

Effective co-creation does not eliminate conflict or complexity; it creates structured ways to work through them. The goal is not consensus at all costs, but informed, negotiated, and transparent decision-making.

  7. The Tipping Point: Indicators of Success

The success of co-creation is not always captured by conventional metrics such as project completion or cost efficiency. Instead, it is often reflected in qualitative shifts in relationships, language, and behavior. These shifts signal a deeper transformation in how stakeholders engage with each other and with environmental issues.

Relational Indicators

Shift in Language and Ownership	Stakeholders begin to use collective language such as "we," "our project," or "our community," indicating a shared sense of responsibility and ownership.
Increased Trust and Openness	Interactions become more constructive, with greater willingness to share perspectives, acknowledge uncertainty, and engage in dialogue.

Knowledge Indicators

Hybrid Knowledge Creation	Technical data is complemented by local, cultural, and experiential insights. For example, formal maps may be enriched with community narratives, values, or historical knowledge.
Improved Mutual Understanding	Different stakeholder groups develop a clearer appreciation of each other's perspectives, constraints, and priorities.

Process Indicators

Constructive Conflict Transformation	Disagreements evolve from adversarial positions into problem-solving discussions, where trade-offs are openly negotiated.
Sustained Engagement	Participation continues beyond initial consultations into implementation and evaluation phases, indicating long-term commitment.

Outcome Indicators

Locally Accepted and Supported Solutions	Decisions are more widely accepted, reducing resistance and increasing the likelihood of successful implementation.
Equitable Distribution of Benefits	Outcomes reflect attention to fairness, particularly for marginalized or vulnerable groups.

A Practical Note

Not all indicators need to be formally measured. In many cases, practitioners can observe these shifts through changes in meeting dynamics, the diversity of voices contributing or the continuity of stakeholder involvement over time.

These signals often provide early evidence that co-creation is moving from process to impact.

  8. Co-Creation as a Decision-Making Tool

Co-creation offers a practical and principled pathway for addressing the complexity of contemporary environmental challenges. By bringing diverse stakeholders into the heart of decision-making, it moves beyond consultation toward shared ownership, mutual learning, and collective responsibility.

This shift not only improves the quality and relevance of outcomes, but also strengthens trust, legitimacy, and long-term commitment. In contexts marked by uncertainty, competing interests, and deep interdependencies, co-creation provides a flexible and adaptive approach that is better aligned with the realities of sustainability transitions.

At the same time, co-creation is not a quick fix or a universally applicable solution. It requires time, resources, institutional openness, and skilled facilitation to be effective. When thoughtfully designed and genuinely implemented, however, it can transform how decisions are made and how relationships are built across sectors and communities.

As environmental governance continues to evolve, co-creation stands out as both a method and a mindset - one that enables more inclusive, equitable, and resilient pathways toward sustainable futures.

Annex: Related concepts Co-creation is part of a broader family of collaborative approaches that emphasize shared value generation, collective intelligence, and participatory governance. While these concepts are often used interchangeably, each has a distinct focus and role within environmental decision-making. Understanding these relationships helps practitioners choose appropriate approaches and combine them effectively across different stages of a project or policy process. Core "Co-Concepts" Co-Design Co-design focuses specifically on the process of developing solutions. It involves stakeholders in shaping interventions, tools, or services so that they reflect user needs and lived experiences. Primary focus: Designing solutions Typical stage: Early to mid (problem-solving and prototyping) In practice: Community workshops to design urban green spaces or climate adaptation measures Co-design can be seen as a key component within co-creation, particularly during the solution development phase. Co-Production Co-production refers to the joint creation of knowledge, services, or outputs by different actors, especially bridging scientific and local expertise. Primary focus: Producing knowledge or delivering services together Typical stage: Throughout the process, especially implementation In practice: Citizen science initiatives, participatory monitoring, or community-based service delivery Co-production is often the operational dimension of co-creation, where collaboration translates into tangible outputs. Co-Governance Co-governance operates at a broader, systemic level, focusing on shared decision-making structures and long-term stewardship. Primary focus: Institutions, power-sharing, and governance systems Typical stage: Long-term and structural In practice: Multi-stakeholder platforms for managing water resources or urban ecosystems Co-governance represents the institutionalization of co-creation, embedding collaboration into ongoing governance frameworks. Positioning Co-Creation Co-creation can be understood as an umbrella concept that brings together these different approaches: It includes co-design when developing solutions It relies on co-production to generate knowledge and implement actions It can evolve into co-governance when collaboration becomes embedded in institutions In this sense, co-creation is both a process and a pathway - from participation to shared governance. BOX: Familiar Ways to Understand Co-Creation Participation, but with real influence Collaboration, but with shared ownership Design thinking, but involving stakeholders throughout Partnerships, but with more equal power Innovation, but grounded in community knowledge Co-creation builds on familiar ideas such as participation, collaboration, and stakeholder engagement, but goes further by emphasizing shared power, joint ownership, and continuous involvement across all stages of decision-making. Related and Complementary Approaches In addition to the core "co-concepts" listed above, several related approaches overlap with or support co-creation: Participatory Planning A long-established approach in urban and environmental planning that emphasizes public involvement in decision-making. Co-creation builds on this tradition but places greater emphasis on shared power and joint ownership. Deliberative Processes Methods such as citizen assemblies or juries that focus on structured dialogue and informed discussion. These are particularly useful for addressing complex or contested issues within co-creation processes. Transdisciplinary Research An approach that integrates academic and non-academic knowledge to address real-world problems. It aligns closely with co-creation's emphasis on knowledge integration and collaboration across boundaries. BOX: A Simple Conceptual Summary Co-design �� How solutions are created Co-production �� How knowledge and outputs are generated Co-governance �� How decisions and systems are managed Co-creation �� The overarching process that connects all three Why This Conceptual Clarity Matters Distinguishing between these concepts is not just academic. It helps practitioners select the right tools and methods for each stage of a project and avoid superficial or mislabelled "participation" . It also helps in designing more coherent and effective collaborative processes Ultimately, this clarity strengthens the ability to move from isolated participatory activities to integrated, systemic approaches to sustainability.
