Here, we show that be responsive local political cultures socio-technical environments, while attending global dimensions interconnectedness issues at stake. Establishing cornerstone inclusive sustainable governance climate-intervention technologies requires (i) recognizing diversity forms intensities engaging, (ii) considering national contexts modes engagement, (iii) tailoring technological idiosyncrasies, (iv) adopting power-sensitive practices, (v) accounting publics' prior experience, (vi) establishing trust procedural legitimacy (vii) engaging with tensions value disagreements.

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.

<sec></sec><sec><p> Sustainable development depends on the integration of economy, society, and environment. Yet, escalating environmental challenges pose threats to both society economy. Despite progress in addressing issues promote sustainability, knowledge gaps scientific research, technological advancement, engineering practice, policy persist. In this review, we aim narrow these by proposing innovation-based solutions refining existing paradigms. Reviewing past research actions, first elucidate evolution sustainability science essence sustainable its assessment. Secondly, summarize current major issues, including global warming climate change, biodiversity loss, land degradation desertification, pollution, as well their relationships with achievement Development Goals (SDGs). Subsequently, review critically evaluates role innovations science, technology, engineering, (iSTEP) synergies advancing SDGs. While sequential may vary based specific contexts or scenarios within iSTEP framework, each component reinforces others, fostering continuous improvement. Finally, offers recommendations future perspectives for formulating roadmaps. Recommendations include a vision promoting interdisciplinary collaboration, encouraging transboundary cooperation among stakeholders endeavors.</p></sec>

Solar geoengineering (also known as solar radiation modification) is garnering more attention (and controversy) among media and policymakers in response to the impacts of climate change. Such debates have become prominent following first-ever field trials stratospheric aerosol injection (SAI) 2022. How lay public perceives remains unclear, however. We use nationally representative samples (N = 3013) Mexico, United States, Kingdom examine perceptions risks benefits, support, policy preferences. also employ an information-framing design that presented individuals with media-style reports on SAI activities differing along three dimensions: location, actor, scale purpose. Support for found be generally higher Mexico; benefits do not differ between countries. Information about has a limited effect. There evidence conducted by universities receive support than those start-up companies.

Abstract Solar geoengineering maintains a vocal presence as stop-gap measure in assessments of climate and sustainability action. In this paper, we map prospective benefits risks, corresponding governance approaches, regarding three major proposals for solar (stratospheric aerosol injection, marine cloud brightening, space-based sunshield). We do so by engaging with 44 focus groups conducted 22 countries split between the global North South. compare results against previous research on public perceptions well wider activities assessment, innovation, decision-making. find that South exhibit greater hope but an arguably richer range concerns geoengineering, context observable inequities action potential geopolitical conflict. Meanwhile, strong, preference multilateral coordination engagement from conduct onwards is offset skepticism effective multilateralism discourse.

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.

Solar geoengineering, also called sunlight reflection or solar radiation modification (SRM), is a potential climate response that would cool the Earth's surface and reduce many other changes by scattering on order 1% of incoming back to space. SRM can only imperfectly correct for elevated greenhouse gases, but it might complement responses risks, while bringing new risks challenges global governance. As alarm calls effective near-term action mount, attracting sharply increased attention controversy, with expanded research governance consultations along ongoing concerns about misuse, overreliance.

It is increasingly evident that maintaining global warming at levels below those agreed in the legally binding international treaty on climate change. i.e., Paris Agreement, going to be extremely challenging using conventional mitigation techniques. While future scenarios of change frequently include extensive use terrestrial and marine carbon dioxide removal second part 21st century, it unproven these techniques can scaled-up reach scale required significantly reduce concentrations atmospheric significant uncertainties detrimental side-effects exist. These issues have led increasing interest so-called “Solar Radiation Modification” whereby mean temperature Earth reduced by either blocking a small fraction sunlight from reaching or Earth’s albedo reflect proportion incident back out space. Here we systematically identify key research gaps associated with two most prominent Solar Modification techniques, Stratospheric Aerosol Injection (SAI) Marine Cloud Brightening (MCB).
