Different dimensions, different vulnerabilities
Open AccessMel George, Leon Clarke et al.ARTICLEEnergy Research & Social Science2026
Energy poverty is multidimensional, yet empirical studies of social disadvantage commonly treat it as a single outcome or examine socioeconomic factors independently. We investigate whether overlapping disadvantages shape different dimensions of energy poverty in different ways. Using nationally representative household data from India, we examine intersections of caste, rural location, education and income poverty across reliable access, afforda…
Agricultural workforce as a potential bottleneck of future cropland availability
Open AccessHongtak Lee, Haewon McJeon et al.ARTICLENature Sustainability2026
Global cropland has historically expanded and this trend is expected to continue as global food demand is projected to grow. However, cropland abandonment is also steadily occurring, with workforce shortages recognized as one of major contributing factors. Here we demonstrate that the agricultural workforce will be a dominant constraint on cropland availability and its future changes, complementing the currently considered environmental constrain…

Rate and growth limits for carbon capture and storage
Open AccessJay Fuhrman, Joe Lane et al.ARTICLEEnvironmental Research Letters2025
CO 2 capture and storage (CCS) in geological reservoirs is expected to play a large role in low-emissions scenarios from multi-sector human Earth system models. Yet these scenarios have often projected near-term CCS deployments that far exceed what is currently planned, l et al one operational. They have also failed to consider regional differences in capacity to deploy large-scale CO 2 capture, transport, and subsurface injection. Here, we updat…
The hydrogen economy can reduce costs of climate change mitigation by up to 22
Open AccessPaul Wolfram, Page Kyle et al.ARTICLEOne Earth2024
In response to the urgent need to mitigate climate change via net-zero targets, many nations are renewing their interest in clean hydrogen as a net-zero energy carrier. Although clean hydrogen can be directly used in various sectors for deep decarbonization, the relatively low energy density and high production costs have raised doubts as to whether clean hydrogen development is worthwhile. Here, we improve on the GCAM model by including a more c…
Ambitious efforts on residual emissions can reduce CO 2 removal and lower peak temperatures in a net-zero future
Open AccessJay Fuhrman, Simone Speizer et al.ARTICLEEnvironmental Research Letters2024
Carbon dioxide removal (CDR) is expected to play a critical role in reaching net zero CO 2 and especially net zero greenhouse gase (GHG) emissions. However, the extent to which the role of CDR in counterbalancing residual emissions can be reduced has not yet been fully quantified. Here, we use a state-of-the-art integrated assessment model to develop a ‘Maximum Sectoral Effort’ scenario which features global emissions policies alongside ambitious…
Provincial-scale assessment of direct air capture to meet China’s climate neutrality goal under limited bioenergy supply
Open AccessHanwoong Kim, Yang Qiu et al.ARTICLEEnvironmental Research Letters2024
China has large, estimated potential for direct air carbon capture and storage (DACCS) but its deployment locations and impacts at the subnational scale remain unclear. This is largely because higher spatial resolution studies on carbon dioxide removal (CDR) in China have focused mainly on bioenergy with carbon capture and storage. This study uses a spatially detailed integrated energy-economy-climate model to evaluate DACCS for 31 provinces in C…
Helping the climate by replacing liquefied natural gas with liquefied hydrogen or ammonia
Open AccessPaul Wolfram, Patrick O’Rourke et al.ARTICLEEnvironmental Research Letters2024
The war in Ukraine caused Europe to more than double its imports of liquefied natural gas (LNG) in only one year. In addition, imported LNG remains a crucial source of energy for resource-poor countries, such as Japan, where LNG imports satisfy about a quarter of the country’s primary energy demand. However, an increasing number of countries are formulating stringent decarbonization plans. Liquefied hydrogen and liquefied ammonia coupled with car…

Regional implications of carbon dioxide removal in meeting net zero targets for the United States
Open AccessChloé Fauvel, Jay Fuhrman et al.ARTICLEEnvironmental Research Letters2023
Net-zero greenhouse gas emission targets are central to current international efforts to stabilize global climate, and many of these plans rely on carbon dioxide removal (CDR) to meet mid-century goals. CDR can be performed via nature-based approaches, such as afforestation, or engineered approaches, such as direct air capture. Both will have large impacts in the regions where they are sited. We used the Global Change Analysis Model for the Unite…
Quantifying airborne fraction trends and the destination of anthropogenic CO 2 by tracking carbon flows in a simple climate model
Open AccessLeeya Pressburger, Kalyn Dorheim et al.ARTICLEEnvironmental Research Letters2023
Atmospheric carbon dioxide (CO 2 ) concentrations have increased as a direct result of human activity and are at their highest level over the last 2 million years, with profound impacts on the Earth system. However, the magnitude and future dynamics of land and ocean carbon sinks are not well understood; therefore, the amount of anthropogenic fossil fuel emissions that remain in the atmosphere (the airborne fraction) is poorly constrained. This w…
Power sector impacts of the Inflation Reduction Act of 2022
Open AccessJohn Bistline, Maxwell Brown et al.ARTICLEEnvironmental Research Letters2023
The Inflation Reduction Act (IRA) is regarded as the most prominent piece of federal climate legislation in the U.S. thus far. This paper investigates potential impacts of IRA on the power sector, which is the focus of many core IRA provisions. We summarize a multi-model comparison of IRA to identify robust findings and variation in power sector investments, emissions, and costs across 11 models of the U.S. energy system and electricity sector. O…

Quantifying the regional stranded asset risks from new coal plants under 1.5 °C
Open AccessMorgan R Edwards, Ryna Cui et al.ARTICLEEnvironmental Research Letters2022
Momentum to phase out unabated coal use is growing globally. This transition is critical to meeting the Paris climate goals but can potentially lead to large amounts of stranded assets, especially in regions with newer and growing coal fleets. Here we combine plant-level data with a global integrated assessment model to quantify changes in global stranded asset risks from coal-fired power plants across regions and over time. With new plant propos…
The role of direct air capture and negative emissions technologies in the shared socioeconomic pathways towards +1.5 °C and +2 °C futures
Open AccessJay Fuhrman, Andrés F Clarens et al.ARTICLEEnvironmental Research Letters2021
The development of the Shared Socioeconomic Pathways (SSPs) and associated integrated assessment modeling (IAM) exercises did not include direct air capture with carbon storage (DACCS) in their scenarios. However, recent more optimistic cost estimates and commercial or pilot-scale DACCS plants have led to increased attention to this technology in both IAM literature and in real-world policy discussions. DACCS is an energy-consuming negative emiss…

GCAM v5.1
Open AccessKatherine Calvin, Pralit Patel et al.ARTICLEGeoscientific Model Development2019
This paper describes GCAM v5.1, an open source model that represents the linkages between energy, water, land, climate, and economic systems. GCAM is a market equilibrium model, is global in scope, and operates from 1990 to 2100 in 5-year time steps. It can be used to examine, for example, how changes in population, income, or technology cost might alter crop production, energy demand, or water withdrawals, or how changes in one region's demand f…
Climate and carbon budget implications of linked future changes in CO 2 and non-CO 2 forcing
Open AccessFelipe Feijoo, Bryan K Mignone et al.ARTICLEEnvironmental Research Letters2019
The approximate proportional relationship between cumulative carbon emissions and instantaneous global temperature rise (the carbon budget approximation) has proven to be a useful concept to translate policy-relevant temperature objectives into CO 2 emissions pathways. However, when non-CO 2 forcing is changing along with CO 2 forcing, errors in the approximation increases. Using the GCAM model to produce an ensemble of ~3000 scenarios, we show t…

Trapped between two tails
Open AccessDerek Lemoine, Haewon McJeonARTICLEEnvironmental Research Letters2013
Climate change policies must trade off uncertainties about future warming, about the social and ecological impacts of warming, and about the cost of reducing greenhouse gas emissions. We show that laxer carbon targets produce broader distributions for climate damages, skewed towards severe outcomes. However, if potential low-carbon technologies fill overlapping niches, then more stringent carbon targets produce broader distributions for the cost …

The contribution of Paris to limit global warming to 2 °C
Open AccessGokul Iyer, Gokul C Iyer et al.ARTICLEEnvironmental Research Letters2015
The international community has set a goal to limit global warming to 2 °C. Limiting global warming to 2 °C is a challenging goal and will entail a dramatic transformation of the global energy system, largely complete by 2040. As part of the work toward this goal, countries have been submitting their Intended Nationally Determined Contributions (INDCs) to the United Nations Framework Convention on Climate Change, indicating their emissions reduct…

Stranded asset implications of the Paris Agreement in Latin America and the Caribbean
Open AccessMatthew Binsted, Gokul Iyer et al.ARTICLEEnvironmental Research Letters2019
Achieving the Paris Agreement’s near-term goals (nationally determined contributions, or NDCs) and long-term temperature targets could result in pre-mature retirement, or stranding, of carbon-intensive assets before the end of their useful lifetime. We use an integrated assessment model to quantify the implications of the Paris Agreement for stranded assets in Latin America and the Caribbean (LAC), a developing region with the least carbon-intens…
