The review, published in Environmental and Sustainability Indicators, examines how renewable energy and other low-carbon interventions could alter that balance. Its central message is not that decarbonization should be slowed, but that it must be designed as more than an engineering project. Solar farms, wind installations, hydropower schemes, electrification programs and clean-cooking technologies can cut emissions and improve health, yet each may also carry environmental costs depending on where and how it is deployed. The authors describe this as a “dual-edged” transition. A fossil-fuel system imposes widespread pollution and climate harms, while a renewable system can shift some burdens toward land, minerals, habitats and communities located near extraction sites or new infrastructure.

The researchers conducted a systematic literature review following the PRISMA 2020 framework, a widely used standard for making evidence searches transparent and reproducible. They searched Scopus, ScienceDirect, PubMed, Taylor & Francis Online and ProQuest for peer-reviewed studies published from January 2020 through May 2025 in English or Indonesian. Their search combined terms related to renewable and clean energy, public health and Southeast Asian countries, including Indonesia, Malaysia, the Philippines, Singapore, Thailand and Vietnam. The review question was structured using the Population–Exposure–Outcome framework: the population included communities and vulnerable groups; the exposure included renewable energy, electrification and clean cooking; and the outcomes included pollution-related disease, mortality, hospital visits, disability-adjusted life years and broader measures of well-being.

That search began with 2,435 records. After 286 duplicates were removed, 2,149 titles and abstracts were screened independently by reviewers. Most were excluded because they examined inappropriate populations, non-renewable energy, outcomes unrelated to health or study designs that did not meet the review’s requirements. Twenty-nine articles progressed to full-text assessment, and five were excluded during quality appraisal. The final synthesis included 24 studies. Three experts in environmental engineering, public health and energy systems were involved in screening, with disagreements resolved through discussion or adjudication by a third reviewer. The authors also assessed the reliability of reviewer agreement and used design-specific tools to judge the credibility of the included evidence.

This methodological detail matters because the evidence spans very different kinds of research. Some studies used observational or panel-econometric methods to examine relationships between energy systems, pollution and health. Others applied quasi-experimental approaches, such as difference-in-differences analysis, to compare outcomes before and after an intervention or between affected and unaffected groups. Economic evaluations estimated costs and benefits, while life-cycle assessments tracked environmental impacts across the stages of an energy technology. Chemical-transport and risk-assessment models were used to connect emissions with population exposure. Because no single method can capture all dimensions of an energy transition, the review matched appraisal tools to study design, applying Joanna Briggs Institute checklists to several analytical approaches and the CASP framework, alongside ISO standards, to modeling and life-cycle work.

The potential health benefits are substantial. Earlier research examined by the authors indicates that cleaner household cooking methods can reduce health problems by as much as 97 percent in some Southeast Asian settings. Local solar systems have been associated with reductions in community illness of up to 25 percent. These interventions can reduce exposure to smoke from solid fuels, lower concentrations of fine particles and toxic gases, and improve household energy reliability. At the regional scale, replacing coal and gas with lower-emission energy could reduce the pollutants that contribute to asthma, chronic respiratory disease, heart attacks and strokes. The review also connects this logic with Global Burden of Disease analyses, which provide standardized estimates of disease incidence, prevalence and disability-adjusted life years. Such measures allow health gains from decarbonization to be compared across countries and over time rather than treated as isolated local outcomes.

But a technology that is clean at the point of use is not necessarily impact-free across its entire life cycle. Solar panels, batteries, transmission systems and electric vehicles require large quantities of metals and minerals, including copper, cobalt, aluminum, nickel, manganese and rare-earth elements. Mining and processing can transform forests, fragment habitat, contaminate soil and water, and increase pressure on species already threatened by land-use change. Hydropower can alter river flows, block fish migration and inundate ecosystems. Roads, transmission corridors and industrial zones can open previously isolated landscapes to further development. The review therefore places biodiversity and ecosystem health alongside air quality and human disease, arguing that an assessment focused only on operational emissions can overlook damage embedded in supply chains and infrastructure.

This problem is especially important for resource-rich countries such as Indonesia, where nickel extraction and processing are tied to global demand for batteries and renewable technologies. The transition is materially interconnected: economies deploying renewable energy may depend on imported ores and concentrates, while the ecological and health risks of extraction are concentrated in the countries that supply them. Research cited in the review suggests that renewable-energy deployment is associated with greater demand for energy-transition minerals and rare-earth imports in both the short and long term. Supply chains concentrated among a small number of producing and refining countries can create geopolitical and economic vulnerabilities, but they can also produce an uneven geography of environmental harm. The communities living near mines, smelters and transport routes may bear pollution and land disruption even when the climate benefits are realized elsewhere.

That uneven distribution turns the energy transition into an issue of energy justice as well as emissions reduction. Justice involves who receives reliable and affordable electricity, who participates in decisions, whose land is used and who is exposed to pollution or displacement. In Indonesia and other parts of Southeast Asia, expanding clean-energy access is often treated primarily as a question of distributing benefits. The review argues that participation and representation deserve equal attention. A project can increase national generating capacity while leaving nearby communities without dependable electricity or meaningful influence over its design. It can also shift pollution from urban power plants to rural mining districts, replacing one pattern of environmental inequality with another. Policies that ignore these dynamics risk undermining public trust and reproducing the very inequities a sustainable transition is supposed to reduce.

The study’s bibliometric analysis helps explain why these trade-offs remain difficult to manage. Mapping 381 related publications revealed two largely separate research clusters: one centered on renewable energy, decarbonization and energy transition, and another focused on Southeast Asia, extraction and economic growth. Explicit epidemiological measures and public-health outcomes were weakly connected to both. Energy justice has begun to appear in the literature, but it remains only loosely linked to evidence about who experiences health improvements and who faces new risks. The authors call for a more integrated research agenda that combines epidemiology, ecology, engineering, economics and community participation. For policymakers, the implication is direct: renewable-energy planning should include health-impact assessments, biodiversity safeguards, life-cycle accounting for minerals, transparent consultation and monitoring of vulnerable populations. The goal is not merely to build a low-carbon power system, but to ensure that cleaner energy also produces healthier communities and living ecosystems.

Particulate matter, an integral part of air quality discussions, encompasses tiny particles suspended in the air that can infiltrate the respiratory system, leading to severe health complications. The harmful effects of PM exposure are well-documented, which include respiratory illnesses, cardiovascular diseases, and even premature death. More alarmingly, various industries contribute significantly to the levels of PM in the atmosphere, and how these contributions have evolved over the past decade is a focal point of this research.

The study employs a comprehensive methodology rooted in statistical analysis and environmental modeling to assess the changes in PM emissions across the industrial spectrum. By tracking data from numerous sectors, the researchers have been able to create a holistic view of how different industries have either mitigated their emissions or, unfortunately, contributed to increased pollution levels. This approach is particularly important as it highlights the need for industry-specific strategies in tackling air quality issues.

Notably, the research identifies key industries that have made substantial progress in reducing their PM emissions. For instance, the automotive industry, which has historically been a significant contributor through motor vehicle exhaust, has implemented stringent regulations and embraced newer technologies aimed at reducing emissions. The transition to electric vehicles and hybrid models has played a pivotal role in this reduction. However, the researchers emphasize that these strides are not universal, with some industries lagging behind in their efforts.

Conversely, certain industries have shown a worrying trend of increased emissions, which poses a significant challenge for national and regional air quality initiatives. The study uncovers that sectors such as construction and mining have experienced upticks in particulate emissions, primarily due to increased activity levels and inadequate regulatory oversight. These findings underscore the need for enhanced monitoring and evaluation frameworks to address emerging sources of pollution effectively.

The geographical analysis within the study reveals that particulate matter emissions are not evenly distributed; they vary greatly across regions. Urban areas, in particular, are identified as hotspots for poor air quality due to higher concentrations of PM. This concentration is exacerbated by factors such as traffic, industrial operations, and fluctuating weather patterns. The research highlights specific metropolitan regions that consistently exceed safe PM levels, advocating for targeted interventions in these areas.

Moreover, the study delves into the health implications of elevated particulate matter levels, particularly in vulnerable populations such as children, the elderly, and those with pre-existing health conditions. Long-term exposure to high levels of PM is linked to increased hospital admissions and healthcare costs, making it a critical issue for public health policymakers. The researchers argue that understanding these health impacts should drive stronger regulatory frameworks and public awareness campaigns.

One of the key takeaways from the research is the pronounced role of data transparency and public reporting in shaping industry behaviors. As citizens become more informed about the sources of pollution in their surroundings, there is increasing pressure on industries to comply with environmental standards. The study advocates for enhanced transparency mechanisms that allow the public to access real-time air quality data, thereby fostering greater accountability among major polluters.

Furthermore, the researchers explore the technological advancements that have emerged in recent years, which provide innovative solutions for reducing PM emissions. For example, the rising adoption of air filtration systems and scrubbers in industrial operations showcases the potential for technology to aid in improving air quality. These innovations not only minimize emissions but can also lead to reduced operational costs in the long run.

The future of air quality management hinges on collaborative efforts among industry stakeholders, governmental bodies, and the scientific community. This research serves as a crucial reference point in engaging multiple stakeholders to align their objectives towards achieving cleaner air. The researchers call for the establishment of cross-sector partnerships that can drive research, investment, and implementation of best practices for emissions control.

As the world continues to grapple with the effects of climate change and environmental degradation, addressing particulate matter pollution must be a priority. The findings from this study will play a pivotal role in guiding future research efforts, policy framing, and public discourse on air quality. It is clear that a multi-faceted approach is necessary to tackle this complex issue effectively, involving not only mitigation strategies but also adaptation and remediation efforts.

In conclusion, the comprehensive assessment conducted by Kim, J., Kim, D., and Jeon, S. underscores the dynamic nature of particulate matter emissions across industries and regions. Their work not only highlights the progress made in some sectors but also calls attention to the significant challenges that remain in others. This research sets a foundation for future studies and initiatives aimed at reducing particulate matter pollution, ultimately striving for a healthier planet and population.

Urban centers worldwide are experiencing rapid population growth, which inevitably leads to increased industrial activity, vehicular traffic, and energy consumption. This cumulative effect has resulted in a pronounced surge in various pollutants that contribute to the deterioration of air quality. Nitrogen oxides, particulate matter, and volatile organic compounds are just a few examples of pollutants that are becoming alarmingly prevalent in urban atmospheres. As cities expand, understanding the sources and consequences of these emissions becomes crucial for public health and environmental sustainability.

One of the key findings of recent research is the stark correlation between urban activities and the rise in greenhouse gas emissions. Urban areas are responsible for a significant portion of global carbon dioxide emissions, primarily stemming from fossil fuel combustion. The alarming data reveals that the pace of these emissions is not just on the rise but accelerating. This trend signals a pressing need for intervention if we are to achieve sustainability targets and mitigate climate change impacts.

The concentration of airborne pollutants is particularly concerning due to their direct impact on respiratory health. Research indicates a troubling increase in respiratory diseases, including asthma and chronic obstructive pulmonary disease, which can be attributed to poor air quality. Vulnerable populations, such as children and the elderly, face the highest risks, necessitating a concerted effort to address these environmental health issues. Municipalities are now tasked with formulating strategies to curb emissions and improve air conditions, with an emphasis on public health policies.

Moreover, the social implications of declining air quality cannot be ignored. Communities in urban areas, particularly those marginalized, often suffer the brunt of pollution exposure. This exacerbates existing inequalities, as these populations tend to have limited access to healthcare and are more susceptible to pollution-related health outcomes. Comprehensive plans must be developed to ensure equitable access to clean air, as well as to raise awareness of the links between air quality and public health.

Policy measures play a pivotal role in addressing the emission crisis in urban settings. Governments are increasingly called upon to implement stringent regulations that limit industrial emissions and promote cleaner transportation options. Transitioning to renewable energy sources and investing in public transit are viable steps that can contribute to reducing urban emissions significantly. Additionally, fostering community engagement and awareness campaigns can empower citizens to partake in initiatives aimed at improving air quality.

Technological advances also offer promising solutions for combating anthropogenic emissions in urban environments. Smart city initiatives employing data analytics can optimize traffic flow, reduce congestion, and subsequently lower vehicle emissions. Furthermore, air quality monitoring systems equipped with real-time data collection make it possible to identify pollution hotspots and formulate targeted responses. The integration of technology and environmental science could provide valuable insights into managing urban air quality more effectively.

Education and research are paramount in combating the challenges posed by urban emissions. Academic institutions and researchers are working collaboratively to develop innovative methods for air quality assessment and pollution control. Studies examining the relationships between urban structures and emissions are crucial to understanding how built environments influence air quality. Findings from such research can guide urban planning and policy decisions, aiming for a holistic approach to sustainable city development.

Public engagement is a crucial tool in raising awareness about air quality issues. Initiatives that encourage community participation in air quality monitoring can foster a collective sense of responsibility. Workshops, educational programs, and engagement platforms can empower residents to take action and advocate for cleaner air. When communities are equipped with knowledge, they become more proactive in demanding policy changes that focus on reducing emissions and improving air quality.

The issue of urban emissions is a multi-faceted challenge that requires collaboration across sectors. As researchers unveil the extent of anthropogenic emissions and their implications on air quality, stakeholders from government, industry, and academia must work together to devise effective strategies. By fostering interdisciplinary partnerships, we can better understand the complexities of urban pollution and develop comprehensive solutions that address this pressing issue.

Ultimately, the future of urban living hinges on our ability to mitigate anthropogenic emissions and safeguard air quality. As populations continue to rise and urban centers grow, we must prioritize sustainable practices that protect both environmental and public health. The insights derived from ongoing research serve as a crucial reminder of our interconnectedness with our urban environments. It is imperative that we take immediate action to ensure cleaner air for future generations.

As we analyze the implications of increasing emissions in urban areas, we must recognize that the challenge is not insurmountable. With concerted effort from citizens, policymakers, and scientists, we can initiate transformative changes that lead to cleaner and healthier urban environments. The task ahead is complex, but success is attainable if we unite in our commitment to improving air quality for all.

It is vital to remember that while urbanization presents challenges, it also opens avenues for innovative solutions. The transition towards greener urban landscapes is not just a necessity but an opportunity to reshape our cities into healthier, more livable spaces. By embracing sustainability as a guiding principle, we have the potential to create urban environments that harmonize economic growth with environmental stewardship.

As we look to the future, the importance of raising awareness about urban emissions cannot be overstated. With a greater understanding of the issue, we can encourage informed public discourse, push for policy changes, and hold stakeholders accountable. The drive for cleaner air is a collective endeavor and one that must continue to gain momentum as urbanization progresses.

In conclusion, the research highlighting the substantial increase in anthropogenic emissions in urban settings emphasizes an urgent call to action. The implications on air quality are significant, reflecting not only on public health but also on social equity and environmental sustainability. It is incumbent upon all of us to take tangible steps towards cleaner air and a healthier urban existence.

Using advanced computational modeling techniques, the research team meticulously mapped the spatial distribution and chemical transformation of pollutants emitted at every major stage of the oil and gas supply chain. This allowed them to isolate and quantify pollution uniquely attributable to upstream activities like drilling and extraction, midstream stages such as transportation and storage, downstream refinery operations, and finally the combustion of fossil fuels in power plants and vehicles. These detailed pollution inventories were then integrated with epidemiological data linking specific pollutants to adverse health outcomes, providing robust estimates of disease incidence and premature mortality nationwide.

Their findings are striking: annually, approximately 91,000 premature deaths in the United States can be directly linked to air pollution generated by oil and gas activities. Moreover, the study attributes over 10,000 cases of preterm birth and 216,000 new childhood asthma diagnoses each year to this pollution source, alongside 1,610 lifetime cancers. Such figures underscore the profound toll air pollution exacts on public health, rivaling or exceeding many other well-known environmental risk factors.

A particularly concerning revelation is the outsized contribution of the fossil fuel combustion phase — the “end-use” stage — which accounts for 96% of these health burdens. Despite the lower emissions from midstream and downstream operations relative to the entire lifecycle, the burning of oil and gas products for transportation and power generation is overwhelmingly responsible for the adverse health outcomes quantified in the study. This finding highlights the urgent need for targeted interventions at the consumer end of the oil and gas economy, alongside upstream emissions controls.

The analysis also identifies geographic hotspots of health impacts correlated with population density and regional industrial activity. California, Texas, New York, Pennsylvania, and New Jersey emerge as the states with the highest total health burdens attributable to oil and gas air pollution. When adjusting for population, New Jersey, the District of Columbia, New York, California, and Maryland show the highest per capita exposure and health impacts, signaling critical areas for environmental justice initiatives.

Beyond aggregate health metrics, the research compellingly documents stark disparities linked to historical and contemporary socio-economic factors. Black and Asian communities bear the greatest health burden from downstream and end-use pollution, particularly in heavily industrialized regions such as Southern Louisiana’s “Cancer Alley” and eastern Texas. Conversely, Native American and Hispanic populations suffer more from upstream and midstream emissions exposure. These disparities are not incidental but trace back to systemic practices like discriminatory zoning and redlining, which have historically confined marginalized groups to living near pollution hotspots such as industrial facilities and major transportation corridors.

The researchers employed a state-of-the-art atmospheric chemistry model capable of simulating complex pollutant transformations under diverse meteorological conditions. This enabled them to chemically distinguish emissions from oil and gas sources from other pollutants in the air, rendering their attribution of health effects highly accurate. Integrating these air quality simulations with census data allowed the team to paint a detailed picture of how pollution’s health impacts intersect with race, ethnicity, and geography across the US.

In addition to domestic consequences, the study highlights transboundary pollution effects, attributing 1,170 early deaths in southern Canada and 440 in northern Mexico to US oil and gas air pollution. This emphasizes the far-reaching nature of fossil fuel emissions and the geopolitical significance of cooperative air quality management in North America.

The study’s authors emphasize the pressing policy implications of their findings. “Our data provides powerful evidence that accelerating the transition away from fossil fuels could save hundreds of thousands of lives in the US every year. This is both an environmental and an equity imperative,” said Dr. Ploy Achakulwisut of SEI. The near-term benefits of reducing oil and gas pollution extend beyond mitigating climate change, offering immediate relief to vulnerable communities that have long suffered disproportionate health burdens.

Lead author Dr. Karn Vohra, now at the University of Birmingham, underscores the innovation behind the research: “By parsing pollution contributions from each oil and gas lifecycle stage, we’ve illuminated where the health impacts are most severe and unequally distributed. This comprehensive approach sets a new standard for environmental health research and policymaking.”

While the study’s estimates are conservative, relying on 2017 emissions data, recent trends indicate a 40% increase in US oil and gas production and an 8% rise in consumption by 2023. Consequently, the true scale of health consequences today is likely even greater. The authors also note that their focus on outdoor air pollution means indoor exposures—another significant health risk—are unaccounted for, potentially underestimating the full burden.

This research represents a vital contribution to understanding the human costs of continued fossil fuel dependence in the United States. It rigorously quantifies how air pollution stemming from oil and gas extraction, processing, and combustion drives widespread and unevenly distributed health harms, laying bare the urgent need for systemic changes in energy and environmental policy. By integrating computational air quality modeling with epidemiology and social data, it opens new avenues for informed decision-making aimed at protecting public health and advancing environmental justice.
