The purpose of this annex is to describe the Quality Assurance/Quality Control (QA/QC) procedures and information quality considerations that are used throughout the process of creating and compiling the Inventory of U.S. Greenhouse Gas Emissions and Sinks. This includes the evaluation of the quality and relevance of data and models used as inputs into the Inventory; proper management, incorporati...

This is the 2019 refinement to the corresponding chapter in the 2006 IPCC Guidelines for National Greenhouse Gases Inventories....

India is a rapidly developing economy with interrelated air quality, sustainable development, and climate change mitigation goals. There are unique challenges to achieving each of these goals as well as potential tradeoffs among them. This study examines the implications of possible future energy, climate, and air pollution control policies and measures in India through 2050. Authors take a scenar...

This U.S. Environmental Protection Agency (EPA) report reviews the state of Health Impact Assessment (HIA) practice in the United States by examining 81 completed HIAs across a range of sectors, including transportation, land use, energy, housing, and natural resource management. The report assesses how HIAs are being conducted, identifies current best practices, and evaluates the extent to which ...

This Health Canada guidance provides a framework for assessing the potential human health effects of air quality within federal impact assessments for major resource and infrastructure projects. It outlines the principles, methodologies, and information expected by Health Canada when reviewing impact statements, helping proponents evaluate how project-related air emissions may affect nearby popula...

The CDC's Health Impact Assessment Resources page provides guidance on using environmental and public health data to support Health Impact Assessments (HIAs) of proposed plans, policies, programmes, and projects. It highlights how the CDC's Environmental Public Health Tracking Network can be used throughout the HIA process—from community engagement and scoping to assessment, monitoring, and evalua...

The Air Quality Categories webpage published by the Environment Protection Authority (EPA) Victoria describes the air quality classification system used to communicate current air pollution conditions and associated health advice. It explains the five air quality categories—Good, Fair, Poor, Very Poor, and Extremely Poor—and the pollutant concentration thresholds used to assign these categories ba...

Audit overview:Clean air is important for health and wellbeing, and is an issue of community concern. The World Health Organization (WHO) reports that statistically significant evidence supports the correlation between poor air quality and negative health impacts. The air we breathe primarily contains nitrogen, oxygen, carbon dioxide, water vapour and various inert gases. It also contains pol...

In order to improve air quality, the European Union introduced the New Air Quality Directive in 2008 and set its Member States strict targets on air pollution concentrations for the most harmful and challenging substances, such as fine particles. The law enforcement relies on a monitoring and reporting system to inform the European Commission and the public, for it is the citizens’ right to be inf...

The National Clean Air Programme (NCAP) was launched in 2019 to improve air quality in India by reducing particulate matter (PM) concentrations by 20-30% by 2024. It was later extended to 2026 with a revised target of a 40% reduction in PM10 levels compared to 2017 (NCAP, 2019). The programme has faced challenges and shortcomings, as highlighted in the preceding 'Tracing the Hazy Air 2022, 2023 an...
