The study evaluated emissions from charcoal, kerosene, LPG, and electricity in Kibera, Nairobi. It found that charcoal and kerosene produce the highest concentrations of pollutants, while LPG and electricity produce low concentrations. Ambient PM2.5 levels in the households were 14.2 times higher than the World Health Organization's 24-hour threshold.

A marine heatwave has affected the west coast of Australia since September 2024, with over 60% of the analyzed region meeting heatwave criteria by early January 2025. The most affected area is off the northwest coast, where temperature anomalies exceeded 1.5 degrees Celsius and some locations remained in a heatwave state for over 120 days. Analysis using the Ocean Climate Shift Index indicates that climate change made these daily ocean surface temperatures at least 20 times more likely on average, with likelihood increasing over 100 times during late November.

The project utilizes the Antares network of eight time-series stations across Latin America to study phytoplankton's role in regulating and supporting ecosystem services, such as carbon sequestration and fisheries support. By integrating in situ data from 40 sampling cruises with remote sensing and bio-geochemical modeling, the team aims to understand how climate-driven changes in the ocean environment affect these services and the coastal populations that depend on them. Initial findings indicate that fish productivity in the South Brazil Bight is likely food-limited, as potential yields based on primary production significantly exceed reported FAO catches.

The document examines unequal exposure to PM2.5 in Bangkok, finding that informal workers and low-income individuals experience higher rates of health symptoms. It highlights a gap between government air-quality data and public perception, particularly in peri-urban districts. The authors recommend six policy measures, including improved public communication, expanded healthcare access, and stricter vehicle emission inspections.

The document examines how socioeconomic factors, such as informal employment and low income, increase exposure to air pollution in Bangkok. It finds a significant gap between government air quality data and public perception, particularly in outer districts. The authors propose six policy measures, including improved public communication, expanded affordable healthcare, and stricter vehicle emission controls, to protect vulnerable populations.

The briefing assesses water quality and nutrient loading in the lower Winnipeg River basin (LWRB), identifying significant exceedances of total phosphorus and certain metals, particularly at the Pine Falls Forebay. It highlights that the Winnipeg River is a major nutrient contributor to Lake Winnipeg, with nutrient exports increasing downstream. The document also notes that climate projections suggest increased precipitation and runoff, which may further impact nutrient loading.

The document details the health of aquatic ecosystems in the lower Winnipeg River basin, utilizing data from the Coordinated Aquatic Monitoring Program (CAMP). It examines benthic macroinvertebrates and fish populations, noting that Lac du Bonnet generally shows the best fish performance and diversity. The text highlights the influence of hydroelectric generating stations on river morphology and habitat, and identifies four species at risk in the region.

The report analyzes air quality around 270 schools in Bengaluru, finding that PM2.5 levels frequently exceed WHO and US EPA standards, particularly during school departure times and winter months. It links this pollution to increased childhood asthma and respiratory issues, and recommends policy interventions such as restricting heavy traffic around schools and increasing monitoring networks.

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.

Mighty Earth's May 2017 update uses satellite monitoring to demonstrate that deforestation continues at soy farms supplying major traders Cargill and Bunge in Brazil and Bolivia. Despite public commitments and pressure from consumer companies, the report identifies 60 square kilometers of new clearing and 120 square kilometers of planned clearing across visited sites. The document highlights a disconnect between the corporate image of traders and the reality on the ground, while detailing the varying levels of support and action from global consumer brands regarding the expansion of deforestation-free soy commitments across South America.

Europe is characterized by strong environmental governance, particularly within the European Union, with successful implementations of climate policies, air quality monitoring, and water resource management. While the region is a leader in biodiversity conservation networks and waste regulation, it continues to face challenges including growing waste volumes, industrial waste legacies in Eastern Europe, and a lack of improvement in the overall conservation status of habitats and species.

The report examines water protection in Estonia's Pandivere and Adavere-Põltsamaa nitrate-vulnerable zones (NVZ), highlighting a disconnect between administrative water management plans and agricultural policy. While groundwater generally remains below the 50 mg/l nitrate limit, 45% of surface water bodies in the NVZ are in moderate or poor condition. A survey of 52 farmers reveals that while they acknowledge the impact of point-source pollution (e.g., manure storage), they are skeptical about the impact of diffuse pollution from fertilizer quantities and feel that NVZ restrictions create an unfair economic disadvantage compared to farmers outside these zones.

The study measured nitrogen (N) and phosphorus (P) levels in aerosols and rainwater in Singapore's Marina catchment area. It found that wet deposition dominated N fluxes, while dry deposition dominated P fluxes, with both showing seasonal variations. The results suggest that atmospheric nutrient concentrations are influenced by both local emissions and transboundary transport, and the N:P ratio of 10.5 indicates a potential tendency toward N-limitation in local aquatic ecosystems.

This document is a draft written reply from the Minister of Water and Environmental Affairs to a National Assembly question regarding air quality, health assessments, and refinery compliance in the Durban South Basin.

This briefing, dated 17 July 2014, is a response from Eskom to the South African Department of Environmental Affairs (DEA) regarding a postponement application for the Hendrina Power Station to comply with Minimum Emission Standards (MES). Eskom outlines current stack emission limits, its lack of plans to upgrade the station for certain pollutants, and provides ambient air quality monitoring data showing non-compliance for particulate matter.

This briefing from Eskom to the Department of Environmental Affairs (DEA) provides additional information regarding an application to postpone compliance with Minimum Emission Standards (MES) for the Grootvlei Power Station. The document addresses DEA requests for time series plots of air quality monitoring and data regarding PM2.5 health and environmental impacts.

This document is a letter from Eskom to the South African Department of Environmental Affairs (DEA) dated 17 July 2014. It provides additional information to support Eskom's February 2014 application to postpone compliance with Minimum Emission Standards (MES) for the Kendal Power Station.

This briefing is a response from Eskom to the South African Department of Environmental Affairs (DEA) regarding an application to postpone compliance with Minimum Emission Standards (MES) at the Kriel Power Station. The document provides specific stack emission limits, a planned compliance timeline involving retrofits and decommissioning, and ambient air quality monitoring data from three stations.

This briefing is a letter from Eskom to the South African Department of Environmental Affairs (DEA) dated 17 July 2014. It provides additional information regarding Eskom's application to postpone compliance with Minimum Emission Standards (MES) at the Matimba Power Station, detailing current emission limits, planned compliance strategies, and ambient air quality monitoring data from the Marapong station.

This briefing from Eskom to the Department of Environmental Affairs (DEA) provides additional information regarding an application to postpone compliance with Minimum Emission Standards (MES) for the Matla Power Station.
