Understanding Public Perception of Carbon Capture

Public perception is the lens through which communities interpret and respond to carbon capture and storage (CCS) projects. It is shaped by a complex interplay of knowledge, trust, values, and external narratives. Without a favorable perception, even technically sound projects can face delays, cost overruns, or outright cancellation. Understanding the components of public perception is therefore essential for project proponents, policymakers, and researchers alike.

Knowledge and Awareness Gaps

A primary barrier to acceptance is the general lack of familiarity with CCS technology. Surveys consistently show that a majority of the public has never heard of CCS or holds only vague ideas about it. This knowledge vacuum is quickly filled by misinformation or skepticism—particularly when the technology is discussed alongside controversial oil and gas operations. Educational initiatives that explain the basics of capture, transport, and storage, as well as the climate rationale, are fundamental. However, information alone is insufficient; it must be delivered by trusted messengers and tailored to local contexts. The IPCC Special Report on CCS notes that awareness campaigns must address not only the science but also the socio-economic implications for affected communities.

The Role of Trust in Stakeholders

Trust is the currency of social license. Communities are far more likely to accept a CCS project if they trust the companies, government agencies, and scientists behind it. Distrust often stems from past environmental injustices, perceived lack of transparency, or a history of broken promises by extractive industries. Building trust requires consistent, honest communication and a demonstrated commitment to community welfare over profit. Independent oversight by third-party experts, such as universities or non-profits, can help bridge the trust gap. The IEA’s analysis of CCUS deployment emphasizes that institutional trust is a critical success factor, particularly in regions with strong civil society engagement.

Risk Perception and Communication

People evaluate risks differently than experts. Statistical probabilities of CO₂ leakage or induced seismicity may be low, but any perceived risk can loom large in public opinion. Effective risk communication acknowledges concerns without dismissing them, presents comparative data (e.g., risks of inaction versus storage risks), and provides clear pathways for monitoring and mitigation. The framing of risk also matters: emphasizing that storage sites are chosen for their geological stability, and that monitoring technology provides early warnings, can reduce anxiety. Successful examples like the Global CCS Institute’s case studies show that when communities are treated as partners in risk management, acceptance improves markedly.

Key Factors Influencing Social Acceptance

Social acceptance is not a single yes-or-no verdict; it evolves over time and varies by location. Several distinct but interconnected factors determine whether a community will embrace or resist a CCS project.

Environmental Concerns

Primary environmental fears include the possibility of CO₂ leakage from storage reservoirs, which could affect groundwater quality or escape into the atmosphere, undermining the climate benefit. Induced seismicity is another concern, especially in regions unfamiliar with geological injection. The perceived risk of long-term containment failure can be mitigated by transparent site selection, extensive geologic characterization, and robust monitoring plans. For projects that involve enhanced oil recovery (EOR), environmental groups may oppose CCS on the grounds that it prolongs fossil fuel dependence—a value-based objection that goes beyond technical risk.

Health and Safety of Local Residents

Nearby communities often worry about acute accidents, such as pipeline ruptures or well incidents. Although CO₂ is not toxic at low concentrations, high concentrations can be asphyxiating. Safety demonstrations, emergency response plans, and localized monitoring help address these fears. In some cases, the presence of existing industrial infrastructure (e.g., oil refineries, petrochemical plants) can either increase acceptance (familiarity with industrial operations) or decrease it (cumulative pollution burden). Local health impact assessments, conducted jointly with community representatives, are essential for building credibility.

Economic Impact on Communities

Economic factors cut both ways. A CCS project can bring jobs during construction and operation, local procurement, and tax revenue. However, fears of declining property values, disruption of agriculture or tourism, and long-term liability for storage sites can fuel opposition. When projects offer direct benefits—such as community benefit agreements, local hiring preferences, or infrastructure upgrades—acceptance often increases. Conversely, if the economic benefits are perceived as flowing to outside corporations while local residents bear the risks, resistance hardens. The study on public attitudes in Nature Climate Change found that economic co-benefits (e.g., new skills, local investment) were among the strongest predictors of support.

Trust in Institutions and Governance

Beyond the immediate project developer, institutional trust extends to the regulatory framework, land-use planning authorities, and intergovernmental coordination. A transparent permitting process, independent oversight, and clear liability rules (e.g., transfer of liability to the state after a specified period) all contribute to a sense of security. In jurisdictions with high corruption levels or weak enforcement, social acceptance is extremely low. On the other hand, where there is a history of successful environmental regulation and community consultation—such as in Norway—acceptance becomes more attainable.

Cultural and Political Contexts

Local values, political leanings, and historical relationships with industry shape acceptance. In some communities, a strong identity tied to fossil fuel extraction may make CCS acceptable as a means of retaining jobs while reducing emissions. In others, a progressive, environmentally focused identity may reject CCS altogether as a “false solution” that delays the transition to renewables. Social license is often negotiated through local media, public meetings, and civil society debates. Understanding these cultural dynamics is as important as understanding the geology of the storage site.

Proven Strategies for Building Acceptance

Drawing on decades of experience in community engagement and technology deployment, a set of best practices has emerged for improving the social license of CCS projects.

Early and Ongoing Community Engagement

Engagement must begin before critical decisions are made, not after plans are finalized. Active listening, adaptation to local feedback, and consistent participation build relationships. Methods include open houses, workshops, advisory panels, online portals, and even site visits to existing CCS facilities. The Norwegian Northern Lights project exemplifies this approach: it held hundreds of meetings with local stakeholders, fishermen, and environmental groups over several years, adapting routes and injection strategies based on feedback. This early investment paid off in widespread acceptance and smooth permitting.

Transparent Communication of Risks and Benefits

Transparency means sharing both the positive and negative aspects of a project without spin. Data on potential environmental impacts, monitoring results, and mitigation measures should be publicly accessible in plain language. Financial transparency regarding costs, funding sources, and benefit-sharing arrangements also builds trust. Regular public reporting and independent audits help maintain credibility. When a project encounters issues (e.g., minor operational incidents), swift and frank disclosure prevents erosion of trust.

Education and Capacity Building

Knowledge empowers communities to make informed judgments. Educational programs can be delivered through schools, universities, local media, and public forums. Simple, interactive tools—like 3D models of storage formations or virtual tours of capture facilities—make the technology tangible. Collaborating with local educators and trusted community figures (e.g., doctors, religious leaders) to deliver content can enhance receptivity. The Canadian Boundary Dam CCS project invested heavily in community education, including school programs and public demonstration days, which significantly increased local support.

Demonstration Projects and Success Stories

Seeing is believing. Operating CCS projects provide concrete evidence that the technology can be safe, reliable, and beneficial. Inviting local leaders, journalists, and skeptical community members to visit existing facilities can be more persuasive than any brochure. Highlighting successful long-term operation (e.g., Sleipner has been injecting CO₂ since 1996 without incident) reinforces credibility. Sharing data on job creation, environmental monitoring, and community co-benefits from demonstration projects helps normalize CCS as a proven climate solution.

International Case Studies: Lessons from Successful Projects

Several countries have achieved notable social acceptance for CCS. Examining these examples reveals common principles and context-specific adaptations.

Norway: Sleipner and Northern Lights

Norway’s approach combines a strong regulatory framework, state ownership in oil and gas, and a culture of social dialogue. The Sleipner project (1996) was the world’s first commercial CCS operation, driven by a carbon tax. Transparency was high: the Norwegian Petroleum Directorate led public consultations, and the government remained the majority stakeholder. The Northern Lights project (ongoing) has built on this legacy by actively engaging fishing communities, re-routing pipelines to avoid sensitive areas, and committing to long-term monitoring. Public acceptance in Norway remains above 70% for CCS, according to recent surveys—a testament to the role of institutional trust and early, inclusive engagement.

Canada: Boundary Dam and Quest

Boundary Dam in Saskatchewan, operational since 2014, faced initial skepticism because it was a first-of-its-kind project on an old coal plant. The utility SaskPower launched an extensive public awareness campaign, including town halls, media tours, and an educational website. Economic benefits were emphasized: the project created 1,500 construction jobs and continues to operate as a profitable EOR venture. Quest in Alberta, operated by Shell, also invested heavily in community relations, forming a community advisory panel and sharing monitoring data openly. Both projects enjoy relatively high local acceptance, though national opinion remains polarized. The key takeaway is that local benefits and continuous engagement can overcome broader political opposition.

Netherlands: Porthos and the Rotterdam Experience

In the Netherlands, the Porthos project aims to transport CO₂ from Rotterdam harbour to depleted offshore gas fields. The Dutch approach is characterized by extensive stakeholder mapping and multi-level governance. National legislation ensures public participation in spatial planning, while local municipalities negotiate direct benefits for affected neighborhoods. The project’s communication strategy emphasizes the compatibility of CCS with the Netherlands’ green transition and the jobs it will preserve in the port industry. Although some NGO-led protests have occurred, the broad coalition of government, industry, and unions has maintained momentum. The Dutch example shows that building acceptance can require years of deliberation and compromise.

Japan: Tomakomai CCS Demonstration

Japan’s Tomakomai project, launched in 2016, injected CO₂ from a hydrogen production plant into offshore reservoirs. The government-led project prioritized community engagement from the planning stage, holding over 150 explanatory meetings with local residents, fishermen, and businesses. Transparent monitoring reports were published regularly, and independent expert panels reviewed safety. Local fishermen were particularly concerned about impacts on fisheries; the project invested in oceanographic studies and compensation mechanisms. After initial resistance, acceptance grew as the project demonstrated zero adverse effects. Tomakomai illustrates that even in a culture with less civil society activism, persistent face-to-face engagement is essential.

Conclusion: The Path Forward

Public perception and social acceptance are not peripheral issues in carbon capture deployment—they are as critical as the technology itself. A project may be geologically ideal and economically viable, but without community support it will stall. The evidence from successful cases points to a set of non-negotiable strategies: start engagement early, communicate transparently, invest in education, build trust through independent oversight, and ensure that local communities share in the benefits. Governments and developers must also recognize that social acceptance is dynamic; it requires continuous investment and adaptation to changing concerns. As nations accelerate their climate commitments, the imperative to deploy CCS at scale will only grow. By prioritizing the social dimensions of CCS alongside its technical readiness, we can create the conditions for rapid, equitable, and enduring carbon management solutions. The future of clean energy depends as much on winning hearts and minds as on engineering breakthroughs.
