The '100 Questions for Air Quality' initiative, led by GovLab and the World Resources Institute, convened 100 global experts to prioritize a data and data science agenda for air quality. The process revealed that the primary challenge is not a lack of data or research, but rather the need to utilize existing knowledge to drive political action and investment in air quality solutions.

A letter from the Centre for Environmental Rights (CER) to Tokiso Dispute Settlement (Pty) Ltd regarding the management of Multi-Stakeholder Reference Group (MSRG) and Implementation Task Team (ITT) meetings for air quality priority areas in South Africa.

The document reports that 94% of 242 analyzed U.S. cities saw an increase in average summer temperatures since 1970, with summer nights warming faster than days. It highlights that 74% of cities experienced at least one additional week of above-normal temperatures, with the most significant increases concentrated in the Southeast and Texas.

The briefing examines the impact of the pandemic on public transit, emphasizing that while ridership has fallen, the system remains essential for emissions reduction and frontline workers. It argues that the crisis provides an opportunity to modernize transit through data science, shift from timetable-based planning to trip-based models, and prioritize dedicated bus lanes over a sole focus on electrification to challenge the dominance of single-occupancy vehicles.

The Centre for Environmental Rights submitted an updated expert report by Dr. Ranajit Sahu to the Minister of Environment, Forestry and Fisheries regarding Eskom's Kendal power station. The report identifies 2,851 exceedances of the atmospheric emission licence (AEL) limit for particulate matter between April 2016 and March 2020. The authors express concern over Eskom's reporting practices, alleging that contraventions are improperly coded as 'Grace' or 'Section 30' exceedances to avoid shutdown or service. The letter argues that these findings, along with a report by Dr. Andrew Gray on premature deaths, are relevant to the pending decision on Eskom's objection to a compliance notice.

The report finds that Eskom's Kendal Power Station recorded 2,851 exceedances of its 100 mg/Nm3 particulate matter (PM) limit between April 2016 and March 2020. Exceedances increased significantly in April 2018 and remained high, with January 2020 recording the highest monthly total of 151. The analysis indicates that existing electrostatic precipitators are failing, and the author recommends either shutting down the plant or rapidly retrofitting all six units with fabric filters to meet AEL and World Bank standards.

The Centre for Environmental Rights, acting for groundWork and Earthlife Africa NPC, sent a letter to the Minister of Environment, Forestry and Fisheries on 12 May 2020, extending the deadline for the government to provide written reasons for amending the Minimum Emission Standards (MES) for sulphur dioxide (SO2) regarding existing solid-fuel combustion installations.

The report analyzes seven European Green Capital (EGC) winners—Bristol, Ljubljana, Essen, Nijmegen, Oslo, Lisbon, and Lahti—across 12 environmental domains to establish 'threshold activities' necessary for reaching the EGC finals. Comparing these to Tallinn, the study finds that while Tallinn excels in air quality, green space proportion, and the use of green electricity in municipal buildings, it lags in CO2 emissions per capita, waste landfilling rates, and the formal adoption of strategic planning documents. Key findings highlight the importance of carbon neutrality targets by 2050, integrated sustainable mobility strategies, and the implementation of 'polluter pays' principles in waste management.

The Centre for Environmental Rights submitted two expert reports to the South African government detailing severe particulate matter (PM) limit exceedances and associated health impacts at Eskom's Kendal power station. Dr. Ron Sahu's analysis found 2,712 PM exceedances between April 2016 and March 2020, noting that electrostatic precipitators are failing. Dr. Andrew Gray's report estimates that emissions caused between 61 and 144 premature deaths annually between 2018 and 2019 and severely exceeded WHO air quality guidelines for SO2, PM2.5, and NOx in the Highveld Priority Area, particularly affecting sensitive receptors like primary schools.

The report finds that Kendal Power Station had 2,712 PM exceedances between April 2016 and March 2020, with frequencies increasing threefold starting in April 2018. The author concludes that electrostatic precipitators are failing and recommends either shutting down the plant or retrofitting it with fabric filters to meet AEL and World Bank standards.

The report details the implementation of a low-cost sensor network to monitor air quality in Acre, Brazil, finding that many municipalities frequently exceeded WHO safety limits for PM2.5, primarily during the dry season months of August and September.

Friends of the Earth International highlights the devastating impacts of climate change through the lens of simultaneous disasters in the Asia-Pacific region: catastrophic bushfires in Australia and severe flooding in Indonesia. The statement condemns the Australian government for denying the role of climate change and continuing to support coal extraction despite massive loss of life, biodiversity, and property. It calls for a global transition away from fossil fuels, increased funding for adaptation and loss and damage in developing countries, and a broader movement for climate justice.

The report argues that unconventional oil and gas (UOG) development, specifically hydraulic fracturing, poses significant risks to human health, water and air quality, and climate stability. It highlights strong evidence linking UOG to adverse birth outcomes and asthma, while noting that methane leakage undermines the role of natural gas as a 'bridge fuel'. The document calls for a rapid transition to renewable energy and recommends that Canadian provinces and territories implement moratoria on new fracking development.

The report advocates for the use of nature-based solutions (NBS) in South African municipalities to address the dual crises of COVID-19 economic devastation and climate vulnerability. It highlights that while national green recovery plans exist, they often require high skills and long lead times. In contrast, NBS—particularly urban tree planting and the removal of invasive alien plants—can provide immediate, low-skill employment for vulnerable populations while mitigating urban heat islands, managing flood risks, and improving public health. The document identifies significant barriers to implementation, including municipal funding shortages, difficulties in quantifying the economic value of natural assets, and rigid public procurement processes.

The document serves as a guide for the public, NGOs, and legal professionals on how to exercise the right to environmental justice in Slovakia. It details the three pillars of environmental democracy—access to information, public participation in decision-making, and access to justice—explaining how these are implemented through the Aarhus Convention and EU directives. The manual specifically outlines Slovak national laws, such as the Administrative Court Procedure Act, and provides practical instructions on filing lawsuits, appealing decisions, and utilizing international remedies like complaints to the European Commission.

A coalition of scientists and health experts is calling on the California Air Resources Board (CARB) to implement a more stringent Advanced Clean Trucks (ACT) rule. The authors argue that heavy-duty vehicles are disproportionately polluting, contributing significantly to global warming and public health crises, particularly in communities of color. They specifically criticize CARB's current proposal, which would result in zero-emissions vehicles making up only 4 percent of trucks on California roads by 2030, and advocate for higher sales standards to accelerate the transition from diesel to zero-emissions technologies.

The document argues that climate change is already causing avoidable injuries, illnesses, and deaths while damaging healthcare infrastructure. It highlights a significant global adaptation gap, noting that funding for health adaptation is less than 1% of international climate adaptation finance. The authors propose a framework for building climate-resilient health systems focusing on workforce knowledge, information systems, service delivery, and adequate financing. Key recommendations include increasing research investments, developing scenario-based integrated adaptation plans, and promoting zero-emission technologies to reduce the overall adaptation burden.

The report examines the technical and economic feasibility of electrifying heavy-duty vehicles (HDVs) in the US, highlighting their potential to significantly reduce NOx, PM2.5, and greenhouse gas emissions. It argues that current battery technology is sufficient for the majority of HDV operating ranges and that total cost of ownership is becoming competitive with diesel. The document recommends a combination of financial incentives, infrastructure investment, and regulatory standards to drive the transition.

The project aims to transition Vientiane Capital's new BRT system from diesel EURO IV buses to low carbon electric vehicles. With a total cost of USD 39.5 million, the initiative includes the procurement of a base fleet of 97 electric buses, the installation of charging equipment, and the creation of a battery management plan for sound disposal and recycling. The project is expected to reduce emissions by 93,070 tCO2eq over its 16-year lifespan and serve as a national flagship for e-mobility in Lao PDR.

The Centre for Environmental Rights (CER), acting on behalf of groundWork and Earthlife Africa NPC, submitted a formal request to Minister Gwede Mantashe for written reasons regarding the promulgation of the updated Integrated Resource Plan (IRP) for Electricity published on 18 October 2019.
