Dr. Ranajit Sahu's expert report concludes that the Updated Air Quality Impact Assessment for the proposed Lephalale Coal Mine confirms that particulate matter emissions will exceed national health standards even with mitigation. He criticizes the assessment for using flawed US EPA methodologies, lacking data on Total Suspended Particulates, and using an unrealistic 'average' truck weight for emissions modeling.

This guide by RMI addresses the challenges of urban freight transport in India, highlighting the environmental and economic costs of current systems and the need for performance improvements to accommodate rapid urbanization.

This executive summary from the Global Climate and Health Alliance (GCHA) examines the health threats posed by smoke from forest fires and bushfires, which are increasingly driven or fueled by climate change. It details the acute health risks to vulnerable populations, provides case studies from Canada, Australia, and Brazil, and recommends urgent forest protection, health system adaptation, and global climate action to limit warming to 1.5°C.

This executive summary from the Global Climate and Health Alliance examines the emerging threat of wildfire smoke and climate change on human health, focusing on case studies from Canada, Australia, and Brazil.

The Centre for Environmental Rights (CER) submitted a statement to the Minister of Environment, Forestry and Fisheries on 28 April 2020, providing expert analysis of air quality and health impacts resulting from emissions at Eskom's Kendal power station. The document presents findings from two expert reports by Dr Ron Sahu and Dr Andrew Gray, highlighting significant exceedances of particulate matter (PM) limits and associated premature deaths and health risks in the Highveld Priority Area.

A technical report by Dr. Ranajit Sahu for the Centre for Environmental Rights analyzing particulate matter (PM) emissions at Eskom’s Kendal Power Station from April 2016 to March 2020. The analysis finds thousands of exceedances of the Atmospheric Emission License (AEL) limit, suggesting that the plant's electrostatic precipitators are failing and recommending the installation of fabric filters or the shutdown of the facility.

This executive summary reports on the 2019 air quality monitoring in the state of Acre, Brazil, utilizing a network of 30 low-cost PurpleAir sensors across 22 municipalities. The study focused on particulate matter (PM2.5) concentrations between June and December 2019, identifying significant violations of World Health Organization (WHO) air quality standards primarily driven by biomass burning from deforestation and pasture management.

The Centre for Environmental Rights (CER), representing groundWork, Earthlife Africa Johannesburg, and the Vukani Environmental Justice Movement in Action, issued a formal request to the Minister of Environment, Forestry and Fisheries for immediate enforcement action against Eskom's Kendal power station. The letter alleges flagrant and chronic non-compliance with Atmospheric Emission Licence (AEL) conditions, specifically regarding particulate matter (PM) limits, and argues that previous government interventions have failed to compel compliance.

A research paper analyzing PM2.5 concentrations in Paris and the Île-de-France region from 2009 to 2018. It finds that while local emission reductions have decreased annual and daily PM2.5 levels, regional transport remains a major contributor, particularly for the highest hourly concentrations, suggesting that regional emission reductions are necessary to meet WHO air quality guidelines.

This report, authored by Dr. Ranajit Sahu and published by the Centre for Environmental Rights, analyzes emissions monitoring data from Eskom power stations between April 2016 and December 2017. The study identifies thousands of exceedances of Atmospheric Emission License (AEL) limits for particulate matter (PM), sulfur oxides (SO2), and oxides of nitrogen (NOx), attributing these failures in part to a lack of modern pollution control technologies and unreliable reporting practices.

The Centre for Environmental Rights (CER), representing various non-governmental and community-based organisations, submitted comments to the Department of Environmental Affairs (DEA) regarding the 2018 Draft Amendments to the National Dust Control Regulations 2013. The CER argues that the draft regulations remain inadequate for protecting human health and the environment, particularly for mining-affected communities, and calls for more rigorous enforcement, better monitoring methods, and the inclusion of specific health-related analyses for toxic dust.

This research paper quantifies the conditions contributing to annual average PM10 and PM2.5 concentrations at two UK EMEP 'supersites' to inform mitigation strategies for long-term human health burdens.

The Centre for Environmental Rights, representing various community and environmental groups, submitted formal objections on 14 February 2014 against Eskom's application to vary the Atmospheric Emission Licence (AEL) for the Duvha Power Station. The objections center on the potential for increased particulate matter (PM) emissions, flawed environmental modelling, and the contradiction of the Highveld Priority Area's air quality goals.

The Centre for Environmental Rights (CER), representing several community and environmental groups, submitted a response to the Nkangala District Municipality opposing Eskom's application to vary the atmospheric emission licence for the Kriel Power Station. The CER argues that the variation would permit increased emissions of particulate matter (PM10) and mercury, leading to significant public health risks and economic costs, while challenging Eskom's dispersion modelling and cost calculations for abatement technology.

The Centre for Environmental Rights (CER), representing various community and environmental groups, submitted formal objections to Eskom's application to vary the Atmospheric Emission Licence (AEL) for the Kriel Power Station. The CER argues that the requested increase in particulate matter (PM) emissions would exacerbate poor air quality in the Highveld Priority Area, cause significant health impacts, and result from Eskom's own poor planning rather than a genuine emergency.

The National Dust Control Regulations, 2012, are draft regulations issued by the South African Department of Environmental Affairs to prescribe general measures for the control of settleable particulate matter (dust) across all areas.

Minutes from a meeting of the SABS SC 146A Source Emissions committee held on 10 March 2009 in Pretoria. The meeting focused on resolving and identifying unresolved emission standards for various industrial processes, including incineration, hazardous air pollutants, and particulate matter (PM), with several disputed items slated for elevation to the Technical Committee (TC).

The Centre for Environmental Rights (CER) provides detailed legal and technical submissions on the draft Air Quality Management By-law for the Ngkawi District Municipality (NDM). The CER recommends aligning the by-laws with national legislation, such as the National Environmental Management: Air Quality Act (AQA) and the National Environmental Management Act (NEMA), and suggests stricter local emission and dust standards to protect human health, particularly given the area's location within a High Priority Area (HPA).

This document is a variation of an Atmospheric Emission Licence (AEL) issued by the Nkangala District Municipality to Eskom Holdings SOC Limited for the Duvha Power Station. The licence, valid until 31 May 2017, regulates atmospheric emissions from listed activities including solid fuel combustion, petroleum product storage, and coal handling, setting specific emission limits for particulate matter (PM), sulphur dioxide (SO2), and nitrogen oxides (NOx).

This annual emissions report for the Duvha Power Station covers the 2015/16 financial year (01 April 2015 to 31 March 2016), detailing verified particulate emissions and calculated gas emissions as required by the station's Atmospheric Emission License.
