Introduction
To address the growing challenges of climate change, many communities in the United States and worldwide have been developing climate action and/or climate adaptation plans [
1,
2]. Climate action plans (CAPs) are mostly concerned with climate change mitigation, including reduction of Green-House Gas emissions (GHGs) and intentional increase of carbon sinks through nature-based solutions, such as deforestation and urban gardens. On the other hand, climate adaptation planning seeks to reduce negative impacts of climate change and to take advantage of some of its benefits. Very few cities in the United States have both a CAP and a climate adaptation plan [
3] but some CAPs include climate adaptation strategies. Integrated climate action and adaptation plans (CAAPs) are becoming more popular as a way to balance climate change mitigation and adaptation priorities [
4] and prevent maladaptations [
5]. In some advanced economies, such as France and Japan, development of integrative multi-sectoral climate action and adaptation plans by all municipalities, is now a national policy requirement [
6,
7] guided by the national guidelines. In the United States, historically, climate action and adaptation planning initiatives have been driven by the bottom-up approach by municipal, tribal, and state initiatives [
8]. When localities pursue federal climate planning policies, they tend to be non-prescriptive, situational, and adopt a de-centered mode of governance [
9]. Due to the absence of uniform federal or state guidelines, municipalities adopt their own methodological frameworks and set their own diversity, equity, and inclusion (DEI) standards. As a result, there is an abundance of locally proposed strategies with limited implementation guidance [
10] and no comparable frameworks for evaluating climate justice [
11].
Michigan has recently positioned itself as a climate leader with its new Michigan Healthy Climate Plan [
12], Clean Energy Future Package (Senate Bills 271, 273, 277, 502, 519) [
13], and the Clean Energy and Jobs Act (House Bills 5120, 5121) [
13]. The state is also home to numerous local plans including CAPs and adaptation plans developed by cities, counties, and tribes. Therefore, Michigan provides an important case study for the entire nation. After the publication of the first Michigan Climate Action Plan [
14], there was a spike in development of local climate action and adaptation plans in 2011-2015. Currently, the interest in local climate planning is high again, stimulated by abundant funding opportunities for local climate planning projects that became available through the Inflation Reduction Act (IRA). The IRA funding allocated through the EPA Climate Pollution Reduction Grants Program aims to reduce the U.S. GHG emissions by 40% by 2030, transition to renewable energy, while also supporting disadvantaged and vulnerable communities [
15]. Since the end of 2023, this program has provided more than
$250 million in grants to help states, major metropolitan areas, U.S. territories, and over 200 indigenous tribes to develop local climate action plans, assess vulnerabilities, and ensure that vulnerable communities are included in the planning [
15].
Low-income and BIPOC (Black, Indigenous, and People of Color) communities, elderly people, young children, pregnant women, and people with disabilities and/or health challenges are often more vulnerable to the negative impacts of climate change, such as heat waves, air pollution, wildfires, and other hazards. Their experiences, however, often remain underrepresented in climate planning because vulnerable populations face many barriers in contributing their voices due to the lack of time, resources, and systematic exclusion from decision making. In the absence of national or state standards for equity and justice in climate adaptation planning, it remains unclear whether these existing and emerging plans address equity and climate justice [
16]. The research study adopts the definition of equity as “the state, quality or ideal of being just, impartial and fair” [
17]. This social concept is closely related to the legal term “justice”, which offers a human rights perspective on climate change, acknowledging its social, economic, health, and other adverse impacts on the underprivileged population. There is a significant gap in understanding how consideration of equity in climate planning is linked to diversity and inclusion of stakeholders participating in the planning process [
11]. Diversity involves various social categories based on class, gender, occupation, income, education, race, ethnicity, age, and ability. They may have very different levels of exposure, sensitivity, and adaptive capacity to climate impacts [
18]. Observable dimensions of diversity include characteristics such as gender, race, ethnicity, and age, but can also include many other characteristics, such as education, socioeconomic background, immigration status, income, and various cultural associations (e.g., religion, ancestry, or social causes) [
19]. Diversity is closely related to the concept of inclusion, which is much more than demographic representation because it involves an authentic sense of belonging [
17].
The lack of authentic inclusion in climate planning is especially acute when it comes to overcoming barriers between indigenous communities and cities. Although Michigan is home to twelve (12) federally acknowledged indigenous tribes that enjoy a special status under federal law and treaties, there are currently no mechanisms for coordinating climate action and adaptation planning between tribal and non-tribal communities. The Anishinaabe communities in Michigan and across the Great Lakes region have a long history of environmental stewardship, rooted in their ongoing relationships with the lands, waters, and other beings of the Great Lakes Region. They maintain important traditional knowledge, shared across generations, including the recent changes in climate and ecosystems. In recent years, tribes have led important efforts in climate action and, especially, climate adaptation planning across the state. For example, in 2014, the White House Climate Champions Program recognized the Sault Ste. Marie Tribe of Chippewa Indians as a Climate Action Champion. Two years later, the Inter-Tribal Council of Michigan, in collaboration with nine federally recognized tribes in Michigan developed and published the guiding document “Adapt: Collaborative Tribal Climate Adaptation Planning”. The document connects tribal-driven climate change vulnerability assessments, identifies climate sensitive tribal assets, and develops adaptation strategies to support coordinated tribal decision-making [
20]. Another important document, Dibaginjigaadeg Anishinaabe Ezhitwaad (Tribal Climate Adaptation Menu) was published by the Great Lakes Indian Fish and Wildlife Commission in 2019, stressing that “many climate adaptation planning tools fail to address the unique needs, values, and cultures of indigenous communities” [
21]. The Tribal Climate Adaptation Menu (TCAM), which was developed by a diverse group of collaborators representing tribal, academic, intertribal, and government entities in Minnesota, Wisconsin, and Michigan, provides a powerful framework to integrate indigenous knowledge, culture, language, and history along with scientific data into the climate adaptation planning process. Blending traditional knowledge, climate science, and environmental planning, this document is intended to empower not only tribal governments, but also federal and state agencies, as well as other organizations in the Great Lakes region to incorporate the Anishinaabe perspectives into a climate adaptation framework [
21]. Strategies presented in this document provide important insights on adaptation planning equally relevant for non-indigenous communities. Climate change and many other ecological crises we face today are the result of the pervasiveness of the Western worldview in decision-making around the globe. While the Western perspectives value exploration, domination, exploitation, and extraction, the Anishinaabe and other indigenous frameworks call for observation, deliberation, recognition, and adaptation. All localities, tribal and non-tribal, could benefit from practicing the “Etuamptmumk” (Two-Eyes Seeing) approach, which integrates both Western and Indigenous knowledge [
22].
Using Michigan as a case study, our inquiry is driven by two following questions:
How have Michigan cities addressed equity in their climate plans across various sectors and what groups of stakeholders have been included in the planning process?
How the Two-Eyes Seeing approach reflected in the TCAM strategies could help cities to improve their planning efforts?
Although this study focuses on Michigan, we hope that the proposed conceptual framework would make a useful contribution to the reanalysis of existing plans and optimization of guidelines for local climate action and adaptation plans nationwide. Therefore, this research study has three interrelated objectives:
To evaluate and compare consideration of equity in climate action and adaptation plans of Michigan cities.
To evaluate and compare inclusion of various groups of stakeholders engaged in development of existing and forthcoming climate action and adaptation plans in Michigan; and
To evaluate how the TCAM framework could inform and improve cities’ climate adaptation planning strategies.
3. Results and discussion
The results of our assessment of equity consideration in all municipal CAPs/CAAPs are summarized in
Figure 2. Based on the consideration of equity calculations, the City of Ann Arbor “A2Zero Plan” [
28] received by far the highest score (54%) and clearly stands out among the other plans based on the number of the included sectors addressed, and the consideration of equity in each individual sector. Areas of particular strength of “A2Zero” include housing, energy decarbonization, waste management, multimodal transportation, and health and wellness (
Figure 3a). Equity measures related to air quality, food security, and business/economic activity are also present but with fewer details about their implementation. Ann Arbor has a population of 123,349 [
29], ranking as the 5th most populous city in Michigan. Best known as home to the University of Michigan, Ann Arbor is a vibrant high-capacity college town with a median income of
$78,546 per household and
$52,276 per capita [
30], much higher than the state and national average. Nevertheless, Ann Arbor’s poverty rate is 23.3%, twice as high as the national average of 11.5% [
30].
Based on our computation of CE, it ranges in all other plans between 21% and 33% (
Figure 2). A closer examination of CE in specific sectors reveals significant differences among the cities. For example, the Detroit Climate Action Plan [
31], discusses equity in business/economic opportunities and community environmental education. It also mentions, without elaborating details, equity in air quality and housing security but omits some other sectors. Detroit is the largest city in Michigan, with a population of 620,376 [
32]. In a striking contrast with Ann Arbor, Detroit’s median household income and per capita income are only
$37,761 and
$22,861 respectively, associated with one of the highest urban poverty rates (31.5%) in the country [
32]. On the other hand, the CAP of Traverse City [
23], pays attention to equity in energy security, while the Climate Adaptation Case Study of Traverse City [
24] considers equity in the access to quality of water resources. Traverse City is a small city with a population of 15,702 enjoying median household income of
$70,700 and per capita income
$48,883 [
33]. An important tourist destination, the city is reputable for its exceptional quality of life, natural beauty, and the presence of numerous environmental advocacy groups. Its poverty rate (11%) is lower than the state and nations averages [
33]. The CAP of East Lansing considers equity in access to green infrastructure, while Marquette’s adaptation plan prioritizes equitable environmental education and health/wellness. The CAP of Royal Oak mentions CE in the context of its energy security and multimodality goals.
Although almost all climate plans in our study acknowledge the importance of equity, very few of them offer concrete steps for achieving it. Most plans include statements about the disproportionate impacts of climate change on vulnerable populations and the importance of environmental justice, but do not offer clear strategies for addressing these issues. This finding echoes the concerns raised by stakeholders during the interviews, emphasizing the need for more substantive equity considerations in the planning processes. Affordable housing, energy decarbonization and efficiency, multi-modal transportation, and nature-based solutions through the expansion of infrastructure emerge as sectors where equity considerations are beginning to take shape concretely in some CAPs. Initiatives aimed at improving energy efficiency in low-income neighborhoods and enhancing mobility through affordable electric vehicle programs reflect an attempt to align climate action with equity goals. However, the effectiveness and reach of these initiatives remain subjects for further evaluation.
Scholarly studies worldwide indicate that CE in climate adaptation goals often goes hand in hand with diversity of stakeholders engaged in development of climate plans and representation of their priorities [
18,
34,
35]. Our computation of IS in development of climate plans in Michigan appears to confirm this connection (
Figure 4). The IS scores of Ann Arbor’s and Detroit’s CAPs stand out as 60% and 58% respectively, followed by other plans with scores below 40%.
The higher scores reflect both broader coalitions of stakeholders involved in developments of plans and their higher levels of engagement. For example, CAPs of Ann Arbor and Detroit reflect collaboration of city planning staff with social justice advocacy groups, universities, local businesses, and environmental advocacy groups (
Figure 5b).
Efforts to engage diverse community stakeholders, particularly those from marginalized and vulnerable groups, were frequently mentioned in climate plans. However, the extent to which these efforts have influenced planning strategies varies. The interviews highlighted initiatives like the Community Collaborative on Climate Change (C4) in Grand Rapids as positive examples of community engagement. Yet, there remains a gap between engaging minority voices and ensuring these voices shape decision-making processes effectively. Stakeholders also identified financial resources as critical to implementing climate action plans, with a mix of federal grants, state funding, and private philanthropy playing roles. However, the most consistent theme was the challenge of securing funding that specifically targets equity goals within climate action initiatives, which is mostly due to the lack of time and personnel dedicated to grant writing. The need for dedicated staff and resources to implement plans was also emphasized by all respondents, pointing to a broader issue of capacity within municipal governments to tackle climate change in an equitable manner.
The twelve (12) federally acknowledged native American tribes that share their land with the State of Michigan enjoy a special status under federal law and treaties [
36]. They are sovereign nations that exercise direct jurisdiction over their members and territory and, under some circumstances, over other citizens residing on their land. Tribal governments provide a wide array of governmental services to their members including climate change mitigation and adaptation planning. Dibaginjigaadeg Anishinaabe Ezhitwaad [
21], in particular, provides a powerful blueprint for tribal and non-tribal communities interested in indigenous approaches to climate adaptation and the needs and values of tribal communities. Organized in a flexible multi-level framework, the Menu outlines fourteen (14) strategies, over fifty (50) approaches, and over one hundred (100) implementation tactics, developed through focus group discussions, workshops, and assessment of existing climate adaptation tools.
Unfortunately, none of the Michigan cities examined in our study acknowledges indigenous people, their land, their sovereign rights, and their ecological knowledge. Their current climate plans are also missing strategies and goals related to cultural practices, traditions, spiritual guidance, reciprocity with non-human beings, and respectful relationship with nature. Such concepts, however, are foundational in tribal adaptation planning [
21] and indigenous culture in general. Indigenous ethics expands the definition of “community” to include not only humans, but also soils, waters, plants, animals, and spiritual beings. It is a moral code of conduct that grows out human kinship with nature, which is a centerpiece of indigenous and many other non-western cultures [
37]. Cities, such as Marquette, Traverse City, and Grand Rapids are located in close proximity to native communities, who have already developed their own climate adaptation plans, such as the Match - e -be -nash -she -wish Band of Pottawatomi Indians Climate Adaptation Plan [
38] and/or have integrated climate change adaptation in their Hazard Mitigation Plans [
39,
40]. The Anishinaabe philosophy recognizing the intrinsic value of the environment is urgently needed today to overcome the climate crisis [
41]. Further research is needed to examine opportunities for Etuapmumk (Two-Eyes Seeing Approach) integrating modern science and indigenous knowledge and cultural practices in environmental action [
22].
Indigenous and traditional knowledge strategies are absent across all municipal plans, without as little as collaboration with tribal stakeholders. This gap underscores a critical area for future investigation of policies that could encourage the “Two-Eyed Seeing Approach”, collaboration with tribal entities, and holistic integration of western and indigenous frameworks of local climate action and adaptation plans. Further research is necessary to develop methodologies for effectively integrating indigenous perspectives, engaging tribal experts, and adopting policy making that honors culturally appropriate practices.
Future efforts are also needed to explore and develop mechanisms for enhancing the engagement of diverse stakeholder groups, including underrepresented BIPOC communities, in the planning process. This could include developing participatory planning frameworks that ensure all voices are heard and valued. There is a need for longitudinal studies to evaluate the implementation and outcomes of climate action and adaptation plans. Such research would provide insights into the effectiveness of different strategies over time, including those inspired by Indigenous knowledge. Future research should consider cross-comparative analyses between municipalities that have incorporated Indigenous and traditional knowledge in their climate plans and those that have not. This would offer empirical evidence of the impact of such integration on climate resilience and social equity.
4. Conclusions
Michigan's approach to climate action is notably fragmented, with only a select few cities having dedicated climate action and/or climate adaptation plans. These existing plans lack cohesion and uniformity, a consequence of the decentralized nature of climate governance in the United States. This results in a patchwork of strategies that may fail to address the environmental challenges facing the state and its regions effectively. To make meaningful progress towards climate goals, Michigan must bolster support and provide guidelines and peer-learning opportunities to harmonize local initiatives with statewide objectives.
Based on the interviews, there is a pronounced need for additional funding, training, and staffing support at the local level, especially for organizing meaningful community engagement and compensating community members for their time, which is often diverted from paid work and family time. Individual communities within the same city have unique needs that, if met with adequate resources and support, could lead to impactful changes at the local level, significantly benefiting the entire community. Another critical gap in current climate plans is the lack of DEI standards. This omission can reduce the effectiveness of climate action and adaptation strategies by not fully addressing the needs of all community members, especially the most vulnerable groups. The integration of DEI principles is vital, echoing findings from both national and international studies that advocate for an inclusive approach to environmental sustainability, one that acknowledges the diverse impacts of climate change on different demographic groups.
Recent federal and state initiatives have provided significant funding for climate action, presenting a valuable opportunity for cities. However, the cities' ability to fully capitalize on these funds is often hampered by insufficient infrastructure, expertise, or planning capacity. Enhancing the capabilities of local governments through training and resource provision is essential to ensure these funds are utilized effectively to enhance climate resilience.
Since the initial publications of the first climate plans by Michigan communities, there has been a notable improvement in the incorporation of diversity of stakeholders and equity concerns in their goals. This evolution indicates a growing recognition of the importance of these factors in effective climate planning. However, none of the municipal plans have included tribal stakeholders and cities could learn valuable lessons in coordinated climate adaptation planning from Native American tribes. These communities use a blend of traditional knowledge and modern science in their approaches, particularly through the "Two-Eyed Seeing" approach, which merges Indigenous and Western knowledge systems to create comprehensive and culturally sensitive solutions. There is no evidence of such collaborative practices in municipal plans, which is a missed opportunity for gaining deeper insights and fostering partnerships.
The insights from Michigan cities resonate with broader trends identified in the national and global scholarly literature on climate action planning [
2]. The recognition of equity as a crucial component of climate action is gaining traction globally, with cities around the world increasingly seeking to integrate social justice into their climate strategies [
42]. However, the translation of equity from a conceptual consideration to a concrete element of planning and implementation remains a significant challenge. Other studies emphasize the importance of meaningful community engagement, transparent decision-making processes, and targeted financial support to ensure equity considerations lead to actionable outcomes [
16]. Moreover, the findings underline the importance of local contexts in shaping climate action plans, suggesting that one-size-fits-all solutions are unlikely to address the unique challenges faced by different communities effectively. As a large Midwestern state with relatively advanced local and state climate policies, Michigan is not unique in facing challenges revealed in our study. Most of our findings and recommendations are applicable nationwide. These recommendations are:
Develop and enforce statewide guidelines that include DEI standards to ensure uniformity while allowing for adaptations to local conditions.
Improve the capability of local governments to manage and implement climate strategies through comprehensive training and resources.
Create forums for cities to share best practices and lessons learned, promoting a collaborative atmosphere that expedites the adoption of effective climate solutions.
Establish formal collaboration frameworks between cities and tribal governments to ensure climate strategies are respectful and integrative of traditional ecological knowledge.
Develop participatory planning processes that actively involve all community members, especially underrepresented groups, to ensure that diverse perspectives are considered in climate planning.
Shift focus from planning to execution, with robust mechanisms to monitor and evaluate the impact of climate strategies, allowing for continuous feedback and improvement.
Our study highlights that while Michigan cities are advancing in their climate action and adaptation strategies, there is a substantial opportunity to improve these initiatives by more thoroughly integrating equity considerations and Indigenous knowledge. This approach not only broadens stakeholder engagement, including pivotal contributions from Indigenous communities, but also ensures that climate strategies are both comprehensive and culturally attuned. The "Tribal Climate Adaptation Menu" provides an essential framework for embedding Indigenous perspectives into climate planning. Municipalities that adopt this framework can achieve a more integrated approach to climate action. As municipal strategies evolve, incorporating traditional knowledge and practices can effectively address today’s environmental challenges while respecting and preserving Indigenous cultural heritage.
