Challenges in Sustainability

Abstract: We are pleased to introduce the third special issue in Challenges in Sustainability entitled Sustainability transformations: Emerging pathways toward safe and just futures for people and the planet.

Abstract: Investing in different futures is an existential challenge that much research within and adjacent to Ecological Economics engages with, yet organizations that recognize this social ecological imperative have few options for funding and implementing radical transformations to the needs and well-being provisioning systems that currently exist. Ecological macroeconomic ideas and EE principles of long term well being and justice on a livable planet will be explored in the context of the housing crisis in Canada, and a rural Ontario community organization attempting to find transformative solutions to the lived, local experience of this crisis. Provisioning systems for housing, when tied to real estate markets, debt money creation, land enclosures, and financialized supply chains, contribute to capital accumulation cycles; it is hardly possible to meet our housing needs, in aggregate, without also perpetuating the form of this provisioning system. The idea presented here, that of Capital Sequestration, proposes to remove capital from markets and `invests' this capital in land trusts as an intentional transformation of financial capital into social and ecological values. Through land and housing trusts as well as non-market funding pathways, Capital Sequestration is a method of investing in the transformation of provisioning systems through the sustained and collective boundary management of financial markets and incommensurable values. This practice offers significant promise as it applies ecological macroeconomic theory work, is grounded in the normative goals of and emerges from empirical research of EE, and meets a pressing need within society for imagining alternative economies.

Abstract: Fossil fuel divestment has quickly become the largest divestment campaign in history, drawing attention to the large discrepancy between national climate commitments and the continued support of the fossil fuel industry. Yet, fossil fuel production and emissions continue to escalate rapidly. Our question is: what's next for the divestment movement? We propose a conceptual framework that identifies two waves of divestment leadership in which public pressure campaigns move towards targeting the extractive economic structures and predatory behaviors that permit fossil fuel extraction, and unsustainable resource extraction more generally, to continue without limit. Building on the three waves model of divestment, we postulate that a fourth wave of fossil fuel divestment organizing has already begun, one that focuses on banks, insurers, and other financiers of fossil fuel projects. Further into the future, we envision a fifth wave of divestment campaigns, whereby divestment is used in climate and environmental activists' arsenal to target firms that engage in environmentally damaging and unjust behaviors such as destructive mining activities, overconsumption, predatory debt or arbitration processes, or Indigenous rights violations. While divestment is not a panacea and does not displace the work of existing post-extractive or climate justice campaigns, we argue that divestment is a powerful tool that can be used to complement and amplify the work of environmental justice activists in other contexts beyond fossil fuels. This paper offers actionable suggestions for current and future activists and frames divestment as a tactic that will proliferate within other environmental movements in the transition towards a post-growth economy.

Abstract: Rooftop solar photovoltaics will play a role in decarbonizing electricity generation and meeting global climate goals. Policymakers can benefit from understanding how their policy choices impact rooftop solar PV adoption. We conduct a case study of Regina, Saskatchewan to determine the extent to which solar policy changes in that Canadian province have impacted the relative desirability of rooftop solar PV. We assess financial returns that can be achieved in Regina under three policy scenarios: net metering, net billing, and net billing with a capital incentive. We use GIS analysis to identify suitable roofs in Regina and assess any shading that may occur. We calculate hourly capacity factors for these roofs using solar irradiation data, temperature data, and shading factors. We match the simulated solar output results with hourly load data to simulate over 4 million potential roof-load combinations and calculate NPV and net monthly return for each combination. We conduct a telephone survey of 451 Regina residents to assess willingness to install solar at different levels of financial return and compare these results to our solar simulations. Our results indicate that a move from net metering to net billing reduced financial returns from rooftop solar and lowered solar potential from 129 Gigawatt-hours (GWh) per year to 99 GWh/yr in Regina. The introduction of a capital incentive grant by the federal government has helped increase solar potential upwards to 120 GWh/yr. The capital incentive grant may also help overcome high discount rates by providing a larger upfront benefit to households that install solar.
