Review of Economics and Policies of Carbon Dioxide Removal

Current Sustainable/Renewable Energy Reports, Journal Year: 2025, Volume and Issue: 12(1)

Published: March 7, 2025

Abstract Purpose of review Despite the increasing political attention and support, high costs many carbon dioxide removal (CDR) technologies remain a barrier to their large-scale deployment. We provide an overview economics for two key CDR options – BECCS DACCS proposed existing policies address “CDR gap” in achieving long-term temperature goals Paris Agreement. Summary Although we lack detailed cost breakdowns actual projects, our suggests that range is generally lower than DACCS. The parameter sustainability biomass feedstock, energy intensity. Recent Findings Cost estimates have increased due experiences from commercial operation, they are increasingly differentiated according feedstock.

Awareness and Understanding of Climate Change for Environmental Sustainability Using a Mix-Method Approach: A Study in the Kathmandu Valley

Sustainability, Journal Year: 2025, Volume and Issue: 17(7), P. 2819 - 2819

Published: March 22, 2025

Climate change is a global phenomenon having wide-ranging social, economic, ecological, and environmental sustainability implications. This study assesses climate awareness, understanding, causes, mitigation measures, practices among residents of the Kathmandu Valley through mixed-method approach. Quantitative surveys with 433 respondents four Focus Group Discussions (FGDs) are conducted diverse demographics. Descriptive statistics used to summarize quantitative data, chi-square (χ2) test measure associations between various The analysis shows that frequently link extreme weather events, particularly flooding, severe hot cold waves, changes in rain precipitation patterns. Furthermore, identify deforestation, industrialization, fossil fuels as primary strategies such afforestation, recycling waste, use renewable energies for long-term sustainability. Similarly, survey also revealed greenhouse gases like carbon dioxide methane major drivers change; individuals, industries, governments held accountable industries key polluters. individuals self-aware adopt sustainable practices, government can play vital role policies promoting energy, waste management, alongside raising awareness. Other highlights have been voices collective action at all levels, which crucial mitigate impact change. addresses gaps comprehensive literacy underscores need targeted educational initiatives foster informed actions within community. Likewise, brings findings policymakers should prioritize inclusive engagement strategies, ensuring adaptation programs accessible, those who less represented discourse, older adults unschooled individuals.

Leveraging ecosystems responses to enhanced rock weathering in mitigation scenarios

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: March 28, 2025

Abstract Carbon dioxide removal (CDR) is deemed necessary to attain the Paris Agreement’s climate objectives. While bioenergy with carbon capture and storage (BECCS) has generated substantial attention, sustainability concerns have led increased examination of alternative strategies, including enhanced rock weathering (EW). We analyse role EW under cost-effective mitigation pathways, by CDR potential basalt applications from silicate (geochemical CDR) ecosystem growth in response phosphorus released (biotic CDR). Using an integrated cycle, energy system model, we show that application forests could triple level sequestration induced compared restricted croplands. also reduces costs achieving Agreement targets as well reliance on BECCS. Further understanding requires improved knowledge rates side-effects through field testing.

Comparing the Effects of Information on Geoengineering Options Support Across Four Online Samples

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: April 29, 2025

Geoengineering represents a set of options to reduce the greenhouse effect that causes global climate change. While public support is necessary for effective governance and implementation, lay has low awareness its existence, types, mechanisms. Prior studies have found providing information can affect support, but there are conflicting results. This study examines what extent these differences may be result survey sampling rather than itself. Survey respondents were randomly assigned receive either basic or extensive about five types geoengineering: space mirrors, stratospheric aerosol injection, ocean fertilization, direct air capture, afforestation. design was replicated across four online samples gathered from address-based sampling, an opt-in panel, Amazon Mechanical Turk (MTurk), college classroom. Across analyses, general consistency effects between sample, classroom with limited exceptions. The MTurk however, overly noisy, even when filtering out responses failed two attention checks. These findings suggest on previous proper used, remain nonrepresentative.
