The World Resources Institute (WRI) has issued a statement condemning the Association of Global Automakers—including GM, Toyota, Fiat-Chrysler, and Nissan—for intervening in litigation to support the Trump administration's attempt to strip California of its power to establish vehicle emission standards for greenhouse gases. WRI argues that this position contradicts the interests of customers, investors, and public health, contrasting these companies with others like Ford, Honda, Volkswagen, and BMW, who support California's standards.

Earthjustice criticizes EPA Administrator Andrew Wheeler's attempt to dismantle the Mercury and Air Toxics Standards (MATS) using a flawed cost-benefit analysis. The report claims that MATS saves up to 11,000 lives annually and prevents $90 billion in health-related costs, primarily through the reduction of fine particulate matter (soot). It highlights the influence of coal industry lobbyists, specifically Bob Murray, and provides personal testimonies from residents in Pennsylvania, Arizona, and North Carolina who suffer from health issues linked to power plant emissions.

The report examines the EPA's proposal to withdraw the finding that regulating hazardous emissions from power plants is "appropriate and necessary," which would effectively gut the Mercury & Air Toxics Standards (MATS). It argues that EPA Administrator Andrew Wheeler is using a "rigged" cost-benefit analysis that ignores the health benefits of reducing fine particulate matter (soot) to favor coal industry profits. The document highlights that MATS prevents between 4,000 and 11,000 premature deaths annually and provides personal accounts from affected residents in Pennsylvania, Arizona, and North Carolina.

The document details the environmental failures of ArcelorMittal South Africa Ltd (AMSA) at its Vanderbijlpark facility, citing extensive air and water pollution, groundwater contamination, and a lack of transparency regarding climate risks. It highlights AMSA's status as one of South Africa's top 10 greenhouse gas emitters and its resistance to carbon taxes and air quality standards.

The document outlines the evolution of the IAI's Scientific Agenda, moving from seven initial research areas to four broad themes. It presents a revised version of these themes—covering climate variability, comparative ecosystem studies, chemical composition of the environment, and human dimensions—to be adopted by the Conference of the Parties.

A 2019 survey of 2,208 registered U.S. voters reveals broad support for government action on climate change, with 70% of respondents favoring such measures. A majority of voters support a national renewable portfolio standard requiring 100% renewable electricity by 2050 and prioritize infrastructure resilience against extreme weather. The data indicates that climate change is a top-tier issue for Democratic voters and that a majority believe transitioning away from fossil fuels will positively impact the economy and jobs.

The clothing and textile industry in Cape Town faces significant risks from water scarcity, energy instability (load shedding), and a linear 'take, make and waste' business model. To build resilience, the Western Cape Industrial Symbiosis Programme (WISP) facilitates resource efficiency and industrial symbiosis, helping businesses divert waste from landfills and reduce water consumption. Key interventions include water pinch analysis, borehole installation, and the adoption of solar PV. The document argues that facilitated, impartial programs like WISP are strategic assets for urban resilience by providing rapid adaptation and trusted information during crises.

The 2019 Impact Report for the Sustainable Ranching Initiative (SRI) details WWF's efforts to conserve grasslands in the Northern Great Plains (NGP). Key activities include expanding grassland bird surveys to 93 ranches, launching a sustainable beef pilot in Montana to improve supply chain traceability, and initiating a transition planning pilot in Nebraska to prevent the conversion of ranches to cropland. The report also highlights community resilience work, including $360,000 in support since 2014, and the 'Conservation Roadshow' which reached over 500 people in Montana to target conservation funding.

The Centre for Environmental Rights (CER) argues that the Highveld Priority Area (HPA) has failed to improve air quality since its 2007 declaration, leaving residents in breach of their constitutional right to a healthy environment. The CER highlights that the 2012 Air Quality Management Plan (AQMP) remains a mere guideline due to a lack of implementing regulations and the granting of 'rolling postponements' for minimum emission standards to major polluters like Eskom and Sasol. The CER demands the publication of enforcement regulations, a final Mid-Term Review of the AQMP, and a cessation of emission standard postponements to meet the 2020 goal of reducing industrial emissions.

The 2017 National Framework for Air Quality Management serves as the operational blueprint for the National Environmental Management: Air Quality Act (AQA) in South Africa. It defines the roles of national, provincial, and municipal governments in managing atmospheric emissions and outlines a governance cycle comprising information management, problem identification, strategy development, standard setting, and enforcement. Key tools introduced include the South African Air Quality Information System (SAAQIS) and the South African Atmospheric Emission Licence and Inventory Portal (SAAELIP). The framework also details the process for declaring priority areas, managing listed activities through Atmospheric Emission Licences (AELs), and fulfilling international obligations regarding greenhouse gases, ozone-depleting substances, and persistent organic pollutants.

The World Weather Attribution (WWA) consortium investigated the possibility of analyzing the effect of climate change on Super Typhoon Mangkhut's rainfall but determined an analysis was not feasible. The decision was based on three primary constraints: the availability of only one high-resolution model for the region, poor quality of public observational data in the affected area (with 50% missing data in most stations), and a lack of manpower and stable funding. The document notes that while greenhouse gases are expected to increase the precipitation of the strongest storms globally, region-specific projections have low confidence. Additionally, the WWA stated that while sea level rise affects storm surges, such impacts are not currently part of their attribution assessments.

The World Resources Institute argues that the Trump administration's proposal to replace the Clean Power Plan will undermine U.S. climate strategy by providing loopholes for power plants, leading to higher greenhouse gas emissions and up to 1,400 premature deaths annually.

The Canadian Association of Physicians for the Environment (CAPE) advocates for the rapid closure of coal plants in Canada to reduce greenhouse gas emissions and mitigate severe health risks from air pollution and mercury. While supporting this transition, CAPE stresses that unemployment and poverty are social determinants of health, requiring a just transition framework including retraining, relocation programs, and extended severance to prevent the health benefits of decarbonization from being offset by economic instability for workers.

Climate Central's analysis of 244 U.S. cities reveals that 93% have seen an increase in cooling degree days and 87% have experienced more warm nights since 1970. The report highlights the role of urban heat islands and the increasing reliance on air conditioning, which costs Americans over $27 billion annually for home cooling as of 2015. While energy efficiency standards may reduce cooling electricity consumption by nearly 20% by 2040, the report warns that fossil-fuel-powered cooling and improper appliance disposal exacerbate climate change.

The oil and gas industry emits over 8 million tons of methane and toxic pollutants annually, contributing to ozone smog and respiratory issues in rural America. Case studies in Texas, Utah, Pennsylvania, Ohio, and New Mexico highlight increased rates of asthma, cancer risks, and other respiratory ailments among residents living near facilities. The report advocates for federal standards to reduce methane emissions by half through leak detection, reduced venting, and gas capture.

The study concludes that human-induced climate change had no significant influence on the occurrence of Storms Eleanor and Friederike. While observational data from the past 40 years show a decrease in near-surface wind speeds, climate models suggest a marginal increase in the probability of extreme hourly winds (0-20%) by the middle of the century due to greenhouse gases. The observed decline in storminess is attributed to factors other than climate change, such as increased surface roughness, aerosols, and decadal variability.

The analysis finds that heat and cold extremes are warming globally in line with average temperatures, with cold extremes in Siberia and Canada warming particularly fast. Extreme daily precipitation is generally increasing at a rate of approximately 7% per degree Celsius, though regional variations exist. While trends in tropical cyclone frequency are difficult to determine, their impacts have increased due to higher precipitation and sea level rise. Drought trends remain complex and highly dependent on the specific definition used.

A coalition of NGOs issued a statement following a U.S. District Court ruling that granted a preliminary injunction against the delay of the Bureau of Land Management's (BLM) methane waste rule. The court found that the BLM failed to follow legal requirements for agency rulemaking, relying on "opinions untethered to evidence" rather than reasoned analysis. The statement highlights that the 2016 rule requires oil and gas companies to reduce methane venting and flaring and perform leak detection and repair on federal public lands. The NGOs argue that allowing methane waste results in significant financial losses for taxpayers, public health risks from toxic pollutants like benzene, and increased climate emissions due to methane's potency as a greenhouse gas.

The Clean Air Task Force challenges EPA Administrator Scott Pruitt on the repeal of the Clean Power Plan, the suspension of methane New Source Performance Standards for the oil and gas industry, and the rollback of air toxics policies, arguing these actions contradict the EPA's mandate to protect public health and rely on scientific evidence.

The authors advocate for a federal champion for active transportation in Canada, citing significant health benefits, such as reducing chronic disease and premature deaths, and environmental benefits, including the reduction of air pollution and greenhouse gas emissions. They propose several federal actions, including creating a dedicated infrastructure fund and establishing a modal share goal.
