A Framework for Augmenting Simulation-Based Building Energy Models with Earth Observational Microclimate Data Using Machine Learning Predictions
Accurate urban building energy modeling (UBEM) is constrained by mismatches between standard climate inputs and actual urban microclimate conditions. This study introduces a scalable, bottom-up, framework that integrates EnergyPlus building energy modeling simulation outputs with Earth observational and geographical-based urban morphology data, which are enhanced through machine learning techniques to improve energy demand predictions in urban se…
Indoor and outdoor fine particulate matter and carbon monoxide concentrations in homes of infants in Nairobi, Kenya
Early life exposure to air pollution is associated with adverse health outcomes in children however few studies have investigated children’s air pollution exposures in urban settings in sub-Saharan Africa (SSA). We measured fine particulate matter (PM 2.5 ) and carbon monoxide (CO) in homes of infants in Nairobi, Kenya and conducted exploratory analysis of exposure factors. Questionnaires captured household characteristics and self-reported air p…
Logistics of Zoning, Zoning for Logistics
Problem, research strategy, and findings: Warehousing and distribution center (W&D) expansion has raised concerns about disparate, adverse health effects from urban freight. While local governments wield several tools to manage logistics-related development, few may be as consequential to public health disparities as zoning. This study synthesizes the state of recent U.S. zoning actions toward W&D, particularly as a tool (or barrier) for protecti…
Distributional impacts of fleet-wide change in light duty transportation
Light-duty transportation continues to be a significant source of air pollutants that cause premature mortality and greenhouse gases (GHGs) that lead to climate change. We assess PM 2.5 emissions and its health consequences under a large-scale shift to electric vehicles (EVs) or Tier-3 internal combustion vehicles (ICVs) across the United States, focusing on implications by states and for the fifty most populous metropolitan statistical areas (MS…
Air quality, health, and equity impacts of vehicle electrification in India
Ambient air pollution in India accounts for 870 000 deaths per year, including 43 000 from road transportation. Vehicle electrification could posit a sustainable solution. However, 3/4th of India’s electric grid is powered by coal, emitting large amounts of PM 2.5 , SO 2 , and NO x . This leads to uncertainty regarding the health benefits and distributional consequences from vehicle electrification. Our results show that if electric vehicles made…
Estimated impacts of forest restoration scenarios on smoke exposures among outdoor agricultural workers in California
As wildfires continue to worsen across western United States, forest managers are increasingly employing prescribed burns as a way to reduce excess fuels and future wildfire risk. While the ecological benefits of these fuel treatments are clear, little is known about the smoke exposure tradeoffs of using prescribed burns to mitigate wildfires, particularly among at-risk populations. Outdoor agricultural workers are a population at increased risk …
Cooking emissions are a major source of racial-ethnic air pollution exposure disparities in the United States
Racial-ethnic minority populations in the US are disproportionately exposed to airborne fine particulate matter (PM 2.5 ), but few national studies have focused individually on the sources that contribute to these disparities. We address this gap by conducting a comprehensive analysis of PM 2.5 exposure disparities by race-ethnicity in the US, focusing on three source-categories: mobile-sources, cooking, and all other sources combined. Our approa…
Quantifying the smoke-related public health trade-offs of forest management
Prescribed burning can mitigate extreme wildfire risk and reduce total smoke emissions. Yet prescribed burns’ emissions may also contribute to smoke exposures in nearby communities. Incorporating public health considerations into forest management planning efforts may help reduce prescribed burn-related exposure impacts. We present a methodological framework linking landscape ecology, air-quality modelling and health impact assessment to quantify…
Historical Redlining Is Associated with Present-Day Air Pollution Disparities in U.S. Cities
High Resolution Image Download MS PowerPoint Slide Communities of color in the United States are systematically exposed to higher levels of air pollution. We explore here how redlining, a discriminatory mortgage appraisal practice from the 1930s by the federal Home Owners’ Loan Corporation (HOLC), relates to present-day intraurban air pollution disparities in 202 U.S. cities. In each city, we integrated three sources of data: (1) detailed HOLC se…
A data framework for assessing social inequality and equity in multi‐sector social, ecological, infrastructural urban systems
Cities are increasingly advancing multiple societal goals related to environmental sustainability, health, well‐being, and equity. However, there are few comprehensive data sets that address social inequality and equity across multiple infrastructure sectors, determinants, and outcomes, particularly at fine intra‐urban spatial scales. This paper: (1) Offers an overarching conceptualization of inequality and equity in multi‐sector urban systems; (…
Racial-ethnic exposure disparities to airborne ultrafine particles in the United States
Ultrafine particles (‘UFP’; <100 nm in diameter) are a subset of fine particulate matter (PM 2.5 ); they have different sources and spatial patterns. Toxicological studies suggest UFP may be more toxic per mass than PM 2.5 . Racial-ethnic exposure disparities for PM 2.5 are well documented; national exposure disparities for UFP remain unexplored due to a lack of national exposure estimates. Here, we combine high-spatial-resolution (census block l…
PM 2.5 polluters disproportionately and systemically affect people of color in the United States
Nearly all major emission categories contribute to the systemic PM 2.5 exposure disparity experienced by people of color.
Socio-economic disparities in exposure to urban restaurant emissions are larger than for traffic
Restaurants and vehicles are important urban sources of particulate matter (PM). Due to the ubiquitous presence of these sources within cities, large variabilities in PM concentrations occur in source-rich environments (e.g. downtown), especially during times of peak activity such as meal times and rush hour. Due to intracity variations in factors such as racial-ethnic composition and economic status, we hypothesized that certain socio-economic g…
Inequity in consumption of goods and services adds to racial–ethnic disparities in air pollution exposure
Fine particulate matter (PM 2.5 ) air pollution exposure is the largest environmental health risk factor in the United States. Here, we link PM 2.5 exposure to the human activities responsible for PM 2.5 pollution. We use these results to explore “pollution inequity”: the difference between the environmental health damage caused by a racial–ethnic group and the damage that group experiences. We show that, in the United States, PM 2.5 exposure is …
Determinants of Cookstoves and Fuel Choice Among Rural Households in India
An inter-comparison of the social costs of air quality from reduced-complexity models
Reliable estimates of externality costs—such as the costs arising from premature mortality due to exposure to fine particulate matter (PM 2.5 )—are critical for policy analysis. To facilitate broader analysis, several datasets of the social costs of air quality have been produced by a set of reduced-complexity models (RCMs). It is much easier to use the tabulated marginal costs derived from RCMs than it is to run ‘state-of-the-science’ chemical t…
Health co-benefits of sub-national renewable energy policy in the US
State and local policy-makers in the US have shown interest in transitioning electricity systems toward renewable energy sources and in mitigating harmful air pollution. However, the extent to which subnational renewable energy policies can improve air quality remains unclear. To investigate this issue, we develop a systemic modeling framework that combines economic and air pollution models to assess the projected sub-national impacts of Renewabl…

High-Resolution Air Pollution Mapping with Google Street View Cars
High Resolution Image Download MS PowerPoint Slide Air pollution affects billions of people worldwide, yet ambient pollution measurements are limited for much of the world. Urban air pollution concentrations vary sharply over short distances (≪1 km) owing to unevenly distributed emission sources, dilution, and physicochemical transformations. Accordingly, even where present, conventional fixed-site pollution monitoring methods lack the spatial re…
Impact, efficiency, inequality, and injustice of urban air pollution
Reducing exposure to air pollution is an important goal for many local and national governments. Disparities in air pollution exposure by race, ethnicity, and socioeconomic class are well documented; reducing these disparities is another important policy target. Meeting both goals requires tools to evaluate how emission reduction options affect average exposures and exposure disparities. Here, we consider the role of emission location in implemen…
Predictors of Daily Mobility of Adults in Peri-Urban South India
Daily mobility, an important aspect of environmental exposures and health behavior, has mainly been investigated in high-income countries. We aimed to identify the main dimensions of mobility and investigate their individual, contextual, and external predictors among men and women living in a peri-urban area of South India. We used 192 global positioning system (GPS)-recorded mobility tracks from 47 participants (24 women, 23 men) from the Cardio…
Long-Term Ozone Exposure and Mortality in a Large Prospective Study
Addressing Global Mortality from Ambient PM 2.5
Ambient fine particulate matter (PM2.5) has a large and well-documented global burden of disease. Our analysis uses high-resolution (10 km, global-coverage) concentration data and cause-specific integrated exposure-response (IER) functions developed for the Global Burden of Disease 2010 to assess how regional and global improvements in ambient air quality could reduce attributable mortality from PM2.5. Overall, an aggressive global program of PM2…
National Patterns in Environmental Injustice and Inequality
We describe spatial patterns in environmental injustice and inequality for residential outdoor nitrogen dioxide (NO2) concentrations in the contiguous United States. Our approach employs Census demographic data and a recently published high-resolution dataset of outdoor NO2 concentrations. Nationally, population-weighted mean NO2 concentrations are 4.6 ppb (38%, p 2.5 hours/week of physical activity). Inequality for NO2 concentration is greater t…
Urban Land Area and Population Growth
In most metropolitan regions throughout the globe, urbanised land area is increasing to accommodate increasing population size. This article provides a simple yet powerful mathematical description of this urban expansion. Specifically, the following scaling relationship is proposed: land area (A) increases proportionally to population size (P) raised to a power (n)— i.e. A ∝ P n . During 1950—2000, this relationship is found to hold well for US C…

Many school districts in the United States allow parents to choose which school their child attends ('school choice' or 'magnet schools') while other school districts require students to attend their nearest ('neighborhood') school. Such policies influence children's transportation. We survey elementary-school parents in St. Paul and Roseville, Minnesota, to discover how children travel to school and underlying factors influencing parent's choice…

Improving Environmental Performance Assessment
Managers, management scholars, regulators, nonprofit organizations, and the media are increasingly using emissions inventory data to measure organizations' environmental performance. Whereas some analysts use total mass emitted, others have applied one or more of the growing number of toxicity‐weighting databases aimed at predicting the environmental and health impacts of emissions. Little research is available to guide analysts in selecting amon…
Potential futures for road transportation CO 2 emissions in the Asia Pacific
Will future transportation carbon dioxide (CO 2 ) emissions per capita in Asia Pacific economies follow historical trends of the now developed world? Evidence to date is inconclusive. A comparison at similar income levels (purchasing power parity) between recent emissions in Asia Pacific countries and historical emissions in developed countries suggests diverging patterns. (A) High‐income Asia economies (Japan, Hong Kong and Singapore –‘low emitt…
