Abstract We present global direct radiative effect (DRE) calculations of carbonaceous aerosols emitted from biomass/biofuel burning addressing the interplay between two poorly constrained contributions to DRE: mixing state black carbon (lensing) and light absorption by organic aerosol (OA) due presence brown (BrC). use parameterization Saleh et al. (2014) which captures variability in OA absorption. The mean is +0.22 W/m 2 +0.12 for externally internally mixed cases, while lensing +0.39...
Current methods of estimating the public health effects emissions are computationally too expensive or do not fully address complex atmospheric processes, frequently limiting their applications to policy research. Using a reduced-form model derived from tagged chemical transport (CTM) simulations, we present PM2.5 mortality costs per tonne inorganic air pollutants with 36 km × spatial resolution source location in United States, providing most comprehensive set such estimates comparable...
Abstract Reliable estimates of externality costs—such as the costs arising from premature mortality due to exposure fine particulate matter (PM 2.5 )—are critical for policy analysis. To facilitate broader analysis, several datasets social air quality have been produced by a set reduced-complexity models (RCMs). It is much easier use tabulated marginal derived RCMs than it run ‘state-of-the-science’ chemical transport (CTMs). However, differences between these not systematically examined,...
Abstract The type, size, and location of renewable energy (RE) deployment dramatically affects benefits to climate health. Here, we develop a ten-region model assess the magnitude health across US We then use this deploying varying capacities wind, utility-scale solar photovoltaics (PV), rooftop PV in different regions US—a total 284 scenarios. Total ranged from $2.2 trillion for 3000 MW wind Upper Midwest $4.2 million 100 California. highest cost effectiveness CO 2 reduction were generally...
Amine scrubbing, a mature post-combustion carbon capture and storage (CCS) technology, could increase ambient concentrations of fine particulate matter (PM2.5) due to its ammonia emissions. To 2.0 Gt CO2/year, for example, it emit 32 Gg NH3/year in the United States given current design targets or 15 times higher (480 NH3/year) at rates typical pilot plants. Employing chemical transport model, we found that latter emission rate would cause an μg PM2.5/m3 nonattainment areas during...
Abstract The distributional effects of a major air regulation in the United State 2015 were analyzed using Berliant and Strauss Index Numbers, set theoretical empirical equity metrics, reduced‐form models that estimate mortality pollutant emissions their source contributions. By viewing pollution on human as an implicit tax, we found progressivity 54% to 56% vertical comparisons inequity 92% 94% horizontal comparisons. introduction proposed policy made 58% more progressive was equitable 70%
Renewable energy and efficiency (EE/RE) can have benefits to both climate public health by reducing emissions of greenhouse gases (GHGs) like carbon dioxide (CO2), air pollutants (APs), including sulfur dioxide, nitrogen oxides, fine particulate matter. Benefits EE/RE been modeled previously, but scalability be limited computational resources necessary run electrical grid atmospheric dispersion models. Here, we present demonstrate EPSTEIN 2.0, a platform that rapidly assess the across 10...
Fine particulate matter (PM2.5) and its gaseous precursors travel long distances, crossing state boundaries. The “good neighbor” provisions of the Clean Air Act require U.S. EPA States to address cross-state transport air pollution that affects states’ ability attain National Ambient Quality Standards. While does not explicitly consider public health benefits such plans, a socially desirable policy would interstate while both maximizing achieving more equitable distribution pollution....
