In summary, the City of Charleston has a coastal geographic setting with a focus on addressing climate-related challenges such as flooding and extreme weather. The plan highlights a transition towards renewable energy and local economic development as part of its climate action strategies.
Question: To what extent does the plan address resilience, mitigation, and adaptation? After providing a brief summary of how it addresses each component, classify the plan as a whole as one of the following: mitigation dedicated, adaptation/resilience dedicated, mitigation only climate action plan, mitigation primary climate action plan, equal mitigation and adaptation climate action plan, or sustainable/green plan.
Answer: Resilience:
The plan addresses resilience by highlighting the importance of enhancing community resilience to climate impacts. It mentions that "both climate adaptation and mitigation solutions are important to achieve community resilience." The plan includes actions that enhance resilience, such as planting trees for carbon sequestration and flood protection, and rooftop solar energy installations for backup power during hurricanes. It also references existing efforts, such as a "climate adaptation plan focused on addressing the impacts of climate change and a Vulnerability Assessment in 2020" (Executive Summary).
Mitigation:
Mitigation is a primary focus of the plan. It aims to reduce greenhouse gas emissions and addresses the root cause of climate change. The plan outlines specific emission reduction goals: "Reduce emissions 56% below 2018 levels by 2030" and "Reduce emissions to net zero by 2050" (Executive Summary). Additionally, it includes mitigation actions such as reducing energy use, waste, and fostering renewable energy (Introduction).
Adaptation:
The plan supports adaptation by building on existing adaptation strategies, particularly those in the City’s Flooding and Sea Level Rise Strategy. It states: "Since adaptation measures...are the primary initiatives in the City’s Flooding and Sea Level Rise Strategy, the Climate Action Plan builds on that base by focusing on climate mitigation measures" (Executive Summary). This indicates that while the primary focus is on mitigation, adaptation is integrated and supported.
Classification:
The plan can be classified as a mitigation primary climate action plan. While it acknowledges and supports adaptation and resilience, the primary emphasis is on reducing greenhouse gas emissions and addressing the root cause of climate change through mitigation strategies.
Question: Does the plan describe a scenario of climate change the planning jurisdiction will face and for which it is planning climate policies for resilience, mitigation, and adaptation? If so, please summarize any such scenario.
Answer: Yes, the plan describes a scenario of climate change that Charleston will face and for which it is planning climate policies for resilience, mitigation, and adaptation.
Climate Impacts: The plan acknowledges that "overuse of fossil fuels has already given rise to an array of flooding, rain bombs, wildfires, landslides, spiking heat waves, droughts, and the threat of global food shortages." Locally, Charleston is experiencing "more flooding, more extreme storms, more sea level rise." (Introduction)
Anthropogenic Emissions: The plan states that "because we burn too much fossil fuel, carbon dioxide (CO2) and methane (CH4) emissions are accumulating rapidly in the atmosphere, creating a greenhouse effect (hence, greenhouse gases), that overly warms the earth; this in turn has led to changes in climate patterns." (Introduction)
Future Emissions Scenario: The plan notes that human-caused carbon emissions "reached a peak in the early part of the 21st century, produced primarily by the energy and transportation sectors of the economy." It further anticipates that "these emissions could double by 2050 —fewer than three decades from now." (Introduction)
These scenarios underline the urgency and necessity for Charleston to implement climate policies focused on resilience, mitigation, and adaptation to address the described and projected climate impacts.

Answer: Climate Policies to Advance Climate Justice:
Community Engagement and Equity Integration:
- Climate Threat Addressed: The plan recognizes that climate change amplifies existing inequities and poses health threats including extreme heat, reduced air quality, natural hazards, exposure to diseases, and mental health impacts. It emphasizes that these effects are not equitably shared across the city.
- Vulnerable Populations: The most vulnerable groups identified include children and pregnant women, people with low income, the elderly, people with disabilities and chronic illnesses, and marginalized people of all races and ethnicities. The plan specifically highlights that these communities already face institutional and systematic oppression that results in less access to resources, capital, and services. (Introduction)
Equity and Climate Justice Taskforce:
- Climate Threat Addressed: The strategy aims to address the inequitable distribution of health and economic benefits resulting from carbon reduction investments and the associated climate protection efforts.
- Vulnerable Populations: Communities of color and low-income populations who have historically been underserved by programs and investments and underrepresented in decision-making on climate policy. These communities face disparities such as lack of low-carbon transportation, inefficient housing, and inability to afford healthy food, primarily due to institutional racial bias and historical discriminatory practices. (Introduction)
Targeted Programs and Infrastructure Changes:

Question: Identify any potential unforeseen maladaptive climate policies. For each identified climate policy, summarize: 1. The climate threat it is addressing. 2. The resilience, mitigation, or adaptation option that the climate policy proposes. 3. Why it may cause inadvertent maladaption.
Answer: Based strictly on the content provided, the document does not explicitly identify potential unforeseen maladaptive climate policies. However, some policies may lead to maladaptation if not implemented carefully. Below are potential areas of concern inferred from the plan:
Tree Planting and Canopy Expansion
Climate Threat Addressed: This policy aims to address urban heat and flooding by increasing carbon sequestration and stormwater absorption.
Option Proposed: The policy proposes planting and prioritizing tree plantings in areas that need it most, such as underserved communities with less overall canopy (see "TABLE 4: CARBON SINKS ACTION PLAN" and "ECOSYSTEM PROTECTION" sections).
Potential Maladaptation: If not carefully managed, tree planting could lead to the selection of non-native or invasive species that might disrupt local ecosystems or require significant water resources, exacerbating water scarcity during droughts.
Renewable Energy Expansion
Climate Threat Addressed: The policy addresses the threat of GHG emissions from fossil fuels and aims to reduce dependence on non-renewable energy sources.
Option Proposed: The plan promotes the adoption of renewable energy and energy efficiency improvements (see "ECONOMIC DEVELOPMENT & RETENTION" and "Buildings" sections).
Potential Maladaptation: Rapid deployment of renewable energy infrastructure, such as solar panels, without adequate planning may lead to land-use conflicts or displacement of natural habitats, potentially affecting local biodiversity. Furthermore, reliance on battery storage could lead to environmental issues related to battery disposal if not managed sustainably.
Flood-Damaged Property Conversion
Climate Threat Addressed: This policy addresses the increased risk of flooding due to sea-level rise and extreme weather events.
Option Proposed: The plan suggests acquiring flood-damaged properties and converting them to natural conditions to capture carbon and water (see "TABLE 4: CARBON SINKS ACTION PLAN").
Potential Maladaptation: There is a risk that converting these properties could lead to the loss of affordable housing if displaced residents are not adequately supported in finding new housing options, thereby exacerbating social inequities.
These summaries highlight potential concerns and should be considered when implementing the climate policies to avoid unintended consequences.
