Public perceptions and support of climate intervention technologies across the Global North and Global South

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: March 6, 2024

Abstract Novel, potentially radical climate intervention technologies like carbon dioxide removal and solar geoengineering are attracting attention as the adverse impacts of change increasingly felt. The ability publics, particularly in Global South, to participate discussions about research, policy, deployment is restricted amidst a lack familiarity engagement. Drawing on large-scale, cross-country exercise nationally representative surveys ( N = 30,284) 30 countries 19 languages, this article establishes first global baseline public perceptions climate-intervention technologies. Here, we show that South publics significantly more favorable potential benefits express greater support for younger age level urgency vulnerability these emerge key explanatory variables, geoengineering. Conversely, concern could undermine climate-mitigation efforts, promote an unequal distribution risks between poor rich countries.

Expanding carbon removal to the Global South: Thematic concerns on systems, justice, and climate governance

Energy and Climate Change, Journal Year: 2023, Volume and Issue: 4, P. 100103 - 100103

Published: April 7, 2023

Conversations on how to assess, innovate, and develop policies for carbon removal are now largely confined the Global North – reflecting a concentration of academic interest (and concern), innovation capacity, early funding initiatives, policy path-dependence in climate, energy, land-use. However, future population growth, emissions trajectories, even concentrations economic technological power) shifting South. Here, after explaining positionality author, this paper summarizes perspectives concerns 90 key academics, technologists, entrepreneurs expanding assessment, innovation, beyond foci within (northern) Europe, US, Japan, Australia. It explores about systems (coupling infrastructure deployment), justice (equity inclusion), governance (including pledges, funding, offsets) markedly differ across South dynamics. discusses such issues intersect with each other, concludes insights research policy.

Heat pump assists in energy transition: Challenges and approaches

DeCarbon, Journal Year: 2023, Volume and Issue: 3, P. 100033 - 100033

Published: Dec. 2, 2023

Aligning with ambitious targets and commitments towards carbon neutrality, countries around the world are desperately seeking an energy transition to cope stark reality of climate crisis surge in demand for heating cooling. Increased penetration renewable power is foreshadowing a shift global dominance, from fossil fuel based heating. However, we have address four underlying challenges transition, including (1) achieve heat electrification, (2) utilize decommissioned thermal plants, (3) meet large-scale storage, (4) puzzle out final "10%" emissions. Given above challenges, put forth pump-assisted approaches break bottleneck facilitate effective incentive strategies policymakers. We highlight that efficiency flexibility pumps regulation enable them push forward immense influence on future heating/cooling supply accounts 50% consumption users last

Public perceptions on carbon removal from focus groups in 22 countries

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: April 24, 2024

Abstract Carbon removal is emerging as a pillar of governmental and industry commitments toward achieving Net Zero targets. Drawing from 44 focus groups in 22 countries, we map technical societal issues that representative sample publics raise on five major types carbon (forests, soils, direct air capture, enhanced weathering, bioenergy with capture storage), how these translate to preferences for governance actors, mechanisms, rationales. We assess gaps overlaps between global range public perceptions currently assessment, innovation, decision-making. In conclusion, outline key expectations informing assessment policy: prioritize engagement more than acceptance research; scrutiny regulation beyond incentivizing innovation; systemic coordination across sectors, levels, borders; underlying causes climate change interrelated issues.

Beyond the new normal for sustainability: transformative operations and supply chain management for negative emissions

International Journal of Operations & Production Management, Journal Year: 2024, Volume and Issue: 44(13), P. 263 - 295

Published: Aug. 26, 2024

Purpose This paper aims to explore three operations and supply chain management (OSCM) approaches for meeting the 2 °C targets counteract climate change: adaptation (adjusting climatic impacts); mitigation (innovating towards low-carbon practices); carbon-removing negative emissions technologies (NETs). We suggest that nor may be enough meet current targets, thus calling NETs, resulting in following question: How can chains reconceptualized NETs? Design/methodology/approach draw on sustainable transitions discourses along with interview data involving 125 experts gathered from a broad research project focused geoengineering NETs. analyze case studies of emerging NETs (biochar, direct air carbon capture storage ocean alkalinity enhancement), leading propositions link between OSCM Findings Although some are promising, there remains considerable variance uncertainty over configurations, efficacy, social acceptability potential risks unintended detrimental consequences. introduce concept transformative OSCM, which encompasses policy interventions foster emergence new industry sectors driven by mandates but lack clear commercial incentives. Originality/value To best authors’ knowledge, this is among first an perspective. It suggests pathway toward structures support effectively tackle change through removal.

Applying the multi-level perspective to climate geoengineering: Sociotechnical bottlenecks for negative emissions and cloud seeding technologies

Published: June 28, 2024

Carbon dioxide removal and negative emissions technologies, such as bioenergy with carbon capture (BECCS) direct air storage (DACCS), may have an important role to play in reducing greenhouse gas (GHGs). Cloud seeding (CS), a controversial form of weather modification, might also help reduce the severity intensity storms address widespread drought from climate change. Nevertheless, costs, technical complexity, social acceptance, other unknown risks so far kept these geoengineering interventions at uncertin levels research deployment response Although large corpus literature sufficiently deals aspects underlying interventions, nontechnical mark fertile territory. This study applies sociotechnical concept Multi-Level Perspective (MLP)—commonly used for analysis sustainability transitions—to explore risks, uncertainties, complexities rolling out BECCS United Kingdom, DACCS States, cloud Australia. We examine interaction MLP across three (niche, regime, landscape), then windows opportunity technological transition bottlenecks. Specifically, we show that align "stretch-and-transform" transition, can be construed "fit-and-conform", CS seen within "stretch-and-conform."

As emerging methods for carbon removal and controversial proposals around solar radiation modification are gaining traction in climate assessments policy debates, a better understanding of how the public perceives these approaches is needed. Relying on qualitative data from 44 focus groups (n = 323 respondents), triangulated with survey conducted 22 countries over 000 participants), we examine role that change beliefs attitudes towards action play formation perceptions modification. We find nationally varying degrees perceived personal harm worry predict support technologies. In addition to different problem, solution – i.e. scope needed − shape publics' assessment. Various tensions manifest themselves reflections potential contribution technologies action, including "buying time vs. delaying action", "treating symptoms tackling root causes", "urgency act effects only distant future". embedded three broader narratives about transformation pathways, each reflecting notions responsibility: (i) behavior change-centred (ii) top-down industry-centred (iii) technology-centred pathways. These results suggest deployment studied hinges them being tied credible system-wide decarbonization efforts as well their ability effectively respond variety impacts.
