Overview
Post Carbon Institute (PCI) is a 501(c)(3) nonprofit organization based in Corvallis, Oregon, whose work addresses the social, economic, and ecological consequences of dependence on finite resources. Its subject areas include fossil fuels, renewable energy, food systems, water, population, climate change, economic growth, and natural-resource depletion. Rather than operating as a conventional consumer brand, PCI functions as an advocacy, research, publishing, and public-education organization whose identity is associated with the idea of preparing communities for a period after—or less dependent on—carbon-intensive growth. The institute was founded in 2003 by Julian Darley and Celine Rich. In its early period, it became associated with discussions of peak oil, a term used to describe the point at which petroleum production reaches a maximum before declining. PCI also promoted relocalization: an approach to resilience that emphasizes local or regional production of food, energy, and goods, alongside more localized governance, economic activity, and culture. This framework connected the organization to wider debates about energy security, climate change, economic vulnerability, and the capacity of communities to respond to systemic shocks. One of the organization's early public-facing projects was its release of the documentary film The End of Suburbia. The film examined the vulnerability of automobile-oriented suburban development to oil depletion and rising energy costs, helping bring peak-oil arguments to a broader public audience. PCI also operated the Relocalization Network, an online network focused on community responses to peak oil and climate change. Its work was part of a broader ecosystem that included the International Forum on Globalization, the Transition Towns movement, EnergyBulletin, and The Oil Drum. In 2009, Asher Miller became executive director. During the subsequent restructuring, PCI concentrated more heavily on research and publishing. Earlier programs were consolidated or discontinued, while the institute broadened its analytical focus beyond peak oil to encompass natural-resource depletion, climate change, economic growth, and human overpopulation. It also entered into partnerships with Transition US and EnergyBulletin. This change positioned PCI less as a single-issue peak-oil organization and more as a platform for examining interconnected limits and transitions affecting modern societies. PCI's fellows have included Bill McKibben, Wes Jackson, David Orr, and Majora Carter. The organization is therefore associated with a network of environmental writers, scholars, and practitioners rather than with a commercial product portfolio. Its principal outputs have consisted of research, books and other publications, educational media, public commentary, and initiatives related to resilience and relocalization. The available reference material does not establish a separate commercial subsidiary, public listing, or parent company.
History
Post Carbon Institute was founded in 2003 by Julian Darley and Celine Rich in response to concerns about the sustainability of an economy dependent on fossil fuels and continual resource-intensive growth. The organization was established as a 501(c)(3) nonprofit and became based in Corvallis, Oregon. Its early identity was strongly connected to peak-oil analysis, sustainability, and the question of how communities might function under conditions of declining or increasingly expensive energy availability. A central concept promoted by PCI was relocalization. In the institute's use of the term, relocalization involves strengthening local capacity to produce food, energy, and goods while also developing more localized forms of governance, economic organization, and culture. The approach was presented as a way to build community resilience in the face of energy constraints, climate disruption, economic instability, and other systemic pressures. This work placed PCI within a wider network of environmental and social movements, including the Transition Towns movement and organizations concerned with globalization and resource depletion. PCI's public profile was also shaped by its release of The End of Suburbia, a documentary examining the relationship between automobile-dependent suburban development and petroleum availability. The film helped communicate peak-oil arguments beyond specialist policy and activist circles. The organization subsequently operated the Relocalization Network, an online network intended to support discussion and community responses to peak oil and climate change. Its activities also intersected with EnergyBulletin and other online forums devoted to energy and ecological limits. In 2009, Asher Miller became executive director. Around this period, PCI restructured its activities and placed greater emphasis on research and publishing. A number of earlier programs were consolidated or discontinued, and the organization expanded its scope. Instead of treating peak oil as its sole or dominant subject, PCI increasingly addressed the interaction among natural-resource depletion, climate change, economic growth, and human overpopulation. The institute also developed partnerships with Transition US and EnergyBulletin. The organization's fellows have included environmental author and campaigner Bill McKibben, agricultural researcher Wes Jackson, environmental scholar David Orr, and community-development leader Majora Carter. These associations reflect PCI's orientation toward interdisciplinary work linking ecological conditions with social and economic responses. PCI is not described in the available sources as a conventional commercial brand. Its recognizable offerings are its research, publishing, educational media, public analysis, and resilience-oriented networks. The reference material does not provide a founding budget, revenue figures, current executive roster, detailed staffing information, or a confirmed list of present programs. It also does not document scandals, lawsuits, acquisitions, public-market activity, or a parent organization.

The End of Suburbia released
[1]PCI released a documentary examining suburban development and the implications of oil depletion, helping popularize peak-oil discussion.
Products and positioning
An independent sustainability and resilience organization focused on the relationship between resource constraints, climate change, economic systems, and community-level responses.
Documentary film
The End of Suburbia
An educational documentary released by Post Carbon Institute that examines automobile-oriented suburban development and its exposure to petroleum depletion and energy-cost pressures. The film became one of PCI's most visible public-facing projects and contributed to wider popular discussion of peak oil, energy dependence, and the resilience of suburban systems.
Online network
Relocalization Network
An online network associated with PCI's work on community responses to peak oil and climate change. It supported the institute's relocalization framework, which emphasizes local production, community resilience, and more localized governance, economic activity, and culture.
Research and publications · 2009
Research and publishing program
PCI's principal program output consists of research, books, reports, essays, and other educational publications on fossil fuels, renewable energy, food, water, population, climate change, economic growth, resource depletion, and resilience. The program became more central after the organization's restructuring around 2009.
Marketing campaigns
- Relocalization
United States · International
PCI promoted relocalization as a community-resilience strategy based on local production of food, energy, and goods, together with localized governance, economic activity, and culture.
Outcome. The concept became a defining part of PCI's early identity and connected the organization with wider transition and community-resilience networks.
Brand decisions
2009
Shift toward research and publishingStrategyBackground
The organization had previously operated several programs associated with peak oil, relocalization, and community responses to climate change.
Action taken
Following leadership and organizational changes, PCI consolidated or discontinued some earlier programs and concentrated more heavily on research and publishing. Its scope expanded to include resource depletion, climate change, economic growth, and human overpopulation.
Aftermath
The restructuring broadened PCI beyond a primarily peak-oil identity and led to partnerships with Transition US and EnergyBulletin.
