  • Uncertainty in determining carbon dioxide removal potential of biochar

    Open AccessSeth Kane, Ahmad Bin Thaneya et al.ARTICLEEnvironmental Research Letters2024

    A quantitative and systematic assessment of uncertainty in life-cycle assessment is critical to informing sustainable development of carbon dioxide removal (CDR) technologies. Biochar is the most commonly sold form of CDR to date and it can be used in applications ranging from concrete to agricultural soil amendments. Previous analyses of biochar rely on modeled or estimated life-cycle data and suggest a cradle-to-gate range of 0.20–1.3 kg CO 2 n…

    Open AccessAhmad Bin Thaneya, Joshua S Apte et al.ARTICLEEnvironmental Research Letters2022

    An exposure-based traffic assignment (TA) model and accompanying analysis framework have been developed to quantify primary and secondary fine particulate matter (PM 2.5 ) exposure due to modeled on-road vehicle flow on a regional network at a high spatial resolution. The Chicago Metropolitan Area transportation network is used to demonstrate the model’s decision-informing power. The study compares the spatially distributed exposure impacts due t…

  • Reduce aviation’s greenhouse gas emissions through immediately feasible and affordable gate electrification

    Open AccessFiona Greer, Jasenka Rakas et al.ARTICLEEnvironmental Research Letters2021

    Aircraft at airport gates require power and air conditioning, provided by fossil fuel-combusting equipment, to maintain functionality and thermal comfort. We estimate the life-cycle greenhouse gas (GHG) emissions and economic implications from electrifying gate operations for 2354 commercial-traffic airports in the world. Here we show that complete electrification could yield GHG reductions of 63%–97% per gate operation relative to current practi…

  • Multi-agent management of integrated food-energy-water systems using stochastic games

    Open AccessMilad Memarzadeh, Scott Moura et al.ARTICLEEnvironmental Research Letters2020

    System-level integration and optimization of food-energy-water systems (FEWS) require coordination of multiple agencies and decision-makers and incorporating their interdependence. In general, such coordination might be hard to achieve. As a result, the literature on FEWS management either optimizes the operations for one sector (or one decision-maker), or models interdependence among the sectors without optimizing their operations. In this artic…

  • Modeling the carbon footprint of fresh produce

    Open AccessEric Bell, Arpad HorvathARTICLEEnvironmental Research Letters2020

    Agriculture is one of the most impactful ways that we interact with the environment. Food demand is expected to increase 70% by 2050 as a result of population growth and the emergence of the global middle class. Meeting the expected demand in a sustainable manner will require an integrated systems-level approach to food production and supply. We present a conceptual framework for estimating the cradle-to-market life-cycle seasonal greenhouse gas …

  • Utility-specific projections of electricity sector greenhouse gas emissions

    Open AccessEmily Grubert, Jennifer Stokes-Draut et al.ARTICLEEnvironmental Research Letters2020

    The environmental profile of electricity is changing rapidly, motivating a need for provider- and time-specific estimates for accurate environmental assessment. This work shows that defensible, provider- and time-specific emissions projections can be derived from two major factors: committed emissions from existing power plants and policy restrictions on future system characteristics. This letter introduces a bottom–up, power plant-based model th…

  • Optimizing dynamics of integrated food–energy–water systems under the risk of climate change

    Open AccessMilad Memarzadeh, Scott Moura et al.ARTICLEEnvironmental Research Letters2019

    Integrated management of food–energy–water systems (FEWS) requires a unified, flexible and reproducible approach to incorporate the interdependence between sectors, and include the risk of non-stationary environmental variations due to climate change. Most of the recently developed methods in the literature fall short of one or more aspects in such integration. In this article, we propose a novel approach based upon fundamentals of decision theor…

  • Drop-in biofuels offer strategies for meeting California’s 2030 climate mandate

    Open AccessMichael N Taptich, Corinne D Scown et al.ARTICLEEnvironmental Research Letters2018

    In 2015, California established a mandate that requires on-road greenhouse gas (GHG) emissions to be reduced by 40% below 1990 levels by 2030. We explore the feasibility of meeting this goal by large-scale commercialization of drop-in biofuels. Drop-in biofuels, although not clearly defined, are a class of fuels that can be produced from biomass and blended with either crude oil or finished fuels without requiring equipment retrofits. This articl…

  • Spatial optimization for decentralized non-potable water reuse

    Open AccessOlga Kavvada, Kara L Nelson et al.ARTICLEEnvironmental Research Letters2018

    Decentralization has the potential to reduce the scale of the piped distribution network needed to enable non-potable water reuse (NPR) in urban areas by producing recycled water closer to its point of use. However, tradeoffs exist between the economies of scale of treatment facilities and the size of the conveyance infrastructure, including energy for upgradient distribution of recycled water. To adequately capture the impacts from distribution …

  • Can life-cycle assessment produce reliable policy guidelines in the building sector

    Open AccessAntti Säynäjoki, J T Heinonen et al.ARTICLEEnvironmental Research Letters2017

    Life-cycle assessment (LCA) is an established methodology that can provide decision-makers with comprehensive data on the environmental impacts of products and processes during the entire life cycle. However, the literature on building LCAs consists of highly varying results between the studies, even when the assessed buildings are very similar. This makes it doubtful if LCA can actually produce reliable data for supporting policy-making in the b…

  • Evaluating the electricity intensity of evolving water supply mixes

    Open AccessJennifer Stokes-Draut, Michael N Taptich et al.ARTICLEEnvironmental Research Letters2017

    Climate change is making water supply less predictable, even unreliable, in parts of the world. Urban water providers, especially in already arid areas, will need to diversify their water resources by switching to alternative sources and negotiating trading agreements to create more resilient and interdependent networks. The increasing complexity of these networks will likely require more operational electricity. The ability to document, visualiz…

    Open AccessDarren Reger, Samer Madanat et al.ARTICLEEnvironmental Research Letters2015

    Transportation agencies are being urged to reduce their greenhouse gas (GHG) emissions. One possible solution within their scope is to alter their pavement management system to include environmental impacts. Managing pavement assets is important because poor road conditions lead to increased fuel consumption of vehicles. Rehabilitation activities improve pavement condition, but require materials and construction equipment, which produce GHG emiss…

  • Unintended greenhouse gas consequences of lowering level of service in urban transit systems

    Open AccessJulia B Griswold, Han Cheng et al.ARTICLEEnvironmental Research Letters2014

    Public transit is often touted as a ‘green’ transportation option and a way for users to reduce their environmental footprint by avoiding automobile emissions, but that may not be the case when systems run well below passenger capacity. In previous work, we explored an approach to optimizing the design and operations of transit systems for both costs and emissions, using continuum approximation models and assuming fixed demand. In this letter, we…

  • Economically and environmentally informed policy for road resurfacing

    Open AccessDarren Reger, Samer Madanat et al.ARTICLEEnvironmental Research Letters2014

    As road conditions worsen, users experience an increase in fuel consumption and vehicle wear and tear. This increases the costs incurred by the drivers, and also increases the amount of greenhouse gases (GHGs) that vehicles emit. Pavement condition can be improved through rehabilitation activities (resurfacing) to reduce the effects on users, but these activities also have significant cost and GHG emission impacts. The objective of pavement manag…
