“…Health-related socio-economic costs attributable to the degradation of air quality from wildfire emissions was assessed using the environmental Benefits Mapping and Analysis Program-Community Edition (BenMAP-CE) version 1.5 17 . BenMAP-CE is an open-source software developed by the US Environmental Protection Agency and is widely used in emission regulation assessment 34,35 and wildfire health impact evaluation 36,37 . BenMAP applies the relationship between the pollution and certain health effects which is often referred to as the health impact function or the concentration-response (C-R) function (derived from Epidemiology studies; Supplementary Figure 10).…”

Recent increases in the frequency and scale of wildfires worldwide have raised concerns about the influence of climate change and associated socio-economic costs. In the western U.S., the hazard of wildfire has been increasing for decades. Here, we use a combination of physical, epidemiological, and economic models to estimate the economic impacts of California wildfires in 2018, including the value of destroyed and damaged capital, the health costs related to air pollution exposure, and indirect losses due to broader economic disruption cascading along with regional and national supply chains. Our estimation shows that wildfire damages in 2018 totaled $148.5 (126.1-192.9) billion (roughly 1.5% of California's annual GDP), with $27.7 billion (19%) in capital losses, $32.2 billion (22%) in health costs, and $88.6 billion (59%) in indirect losses. Our results reveal that the majority of economic impacts related to California wildfires may be indirect and often affect industry sectors and locations distant from the fires (e.g., 52% of the indirect losses-31% of total losses-in 2018 were outside of California). Our findings and methods provide new information for decision-makers tasked with protecting lives and key production sectors and reducing the economic damages of future wildfires.

“…Case V is adopted for exploring the impacts of future climate change on BVOC emissions by using the current BVOC emission factors and 18% tree cover fraction in 2014 and meteorological parameters in 2050 under the RCP8.5 scenario. Hourly meteorological parameters in 2050 were obtained from downscaled global bias-corrected climate model output data for the year 2050 from the Community Earth System Model (CESM1) that participated in phase 5 of the Coupled Model Intercomparison Experiment (CMIP5) ( last accessed: 10th June, 2021), which has been widely used in previous studies for investigating impacts of future climate change on California’s meteorological conditions and air quality. , The dynamic downscaling procedure is detailed in Zhao et al…”

Effects of Anthropogenic and Biogenic Volatile Organic Compounds on Los Angeles Air Quality

Assessing the role of volatile organic compounds (VOCs) in production of ozone and secondary organic aerosol (SOA) is especially important in light of ongoing policy goals. Here, we estimated the ozone formation potential (OFP) and SOA formation potential (SOAP) of anthropogenic and biogenic VOC emissions to evaluate (1) anthropogenic VOCs and associated sectors that dominate OFP and SOAP and (2) the potential impacts of enhanced biogenic VOCs from urban greening programs on air quality in Los Angeles county. In the present-day scenario, ethylene had the largest OFP followed by m & p-xylene, toluene, propylene, and formaldehyde. The top five contributors to SOAP were toluene, mineral spirits, benzene, heptadecane, and hexadecane. Mobile and solvent sources were the dominant VOC sources for both OFP and SOAP. The potential increases in biogenic VOC emissions due to future urban greening had significant effects on urban air quality that offset the benefits of reducing anthropogenic VOC emissions. This study demonstrates that urban greening programs in Los Angeles county, and likely other cities as well, need to account for both anthropogenic and biogenic VOC contributions to secondary pollution, and greening cities should consider using vegetation types with low VOC emissions to avoid further degradation to urban air quality.

“…no mortality included for people under 25, will also underestimate mortality. In addition, related factors such as changes in healthcare system(s), population vulnerabilities, increasing urbanization and/or changes in the composition of the future air pollution mix are generally not being considered but would influence projections [49,103]. Finally, imbedded in some of these factors is the differential impacts of air pollution on demographic groups, with lower socioeconomic conditions generally linked to higher air pollution exposures [104].…”

Future air quality will be driven by changes in air pollutant emissions, but also changes in climate. Here, we review the recent literature on future air quality scenarios and projected changes in effects on human health, crops and ecosystems. While there is overlap in the scenarios and models used for future projections of air quality and climate effects on human health and crops, similar efforts have not been widely conducted for ecosystems. Few studies have conducted joint assessments across more than one sector. Improvements in future air quality effects on human health are seen in emission reduction scenarios that are more ambitious than current legislation. Larger impacts result from changing particulate matter (PM) abundances than ozone burdens. Future global health burdens are dominated by changes in the Asian region. Expected future reductions in ozone outside of Asia will allow for increased crop production. Reductions in PM, although associated with much higher uncertainty, could offset some of this benefit. The responses of ecosystems to air pollution and climate change are long-term, complex, and interactive, and vary widely across biomes and over space and time. Air quality and climate policy should be linked or at least considered holistically, and managed as a multi-media problem. This article is part of a discussion meeting issue ‘Air quality, past present and future’.
