Limiting global temperature increases to below 1.5 °C requires reductions in Short-Lived Climate Pollutants (SLCPs), like methane, black carbon, and hydrofluorocarbons (HFCs), which is rarely reflected in targets within Nationally Determined Contributions (NDCs). Colombia's 2020 NDC is explored as a case study for how Governments can integrate SLCP mitigation targets into climate change commitment...

In this article, authors compile a detailed road transport inventory for greenhouse gases and air pollutants to explore energy emissions from alternative policy scenarios for the Kenya road transport sector. In 2010, road transport emissions accounted for 61% of total nitrogen oxides emissions in Kenya, 39% of fine particulate matter, 20% of carbon dioxide. In the business as usual scenario, road ...

The objective of this report is to highlight the opportunities in the ASEAN region for more equitable and inclusive policymaking on air pollution – in terms of developing evidence-based policies through use of gender disaggregated data collection and analysis and in terms of the impacts of their implementation. We highlight here the unequal burdens of air pollution by sharing ASEAN region case stu...

Limiting global temperature increases to 1.5 °C while respecting ‘the right to health’ requires substantial reductions in Short-Lived Climate Pollutants (SLCPs), including methane, black carbon and hydrofluorocarbons, and co-emitted air pollutants. This study evaluates the inclusion of SLCP and air pollutant mitigation within Nationally Determined Contributions (NDCs) that were submitted between 2...

Core requirements for the EU to to protect human health and the environment as a whole and to combat emissions of pollutants at the source and to identify and implement the most effective emission reduction measures at local, national and Community level....

This report describes the principles and methodologies to be used for the demonstration of the equivalence of methods other than the EU reference methods. It is intended for use by laboratories nominated by National Competent Authorities (see Directive 2008/50/EC) to perform the tests relevant to the demonstration of equivalence of ambient-air measurement methods. The building blocks of the equiva...

CARB provides standard procedures for maintaining and operating air monitoring stations and detailed instructions for acceptance testing, maintaining, troubleshooting, and calibrating specific analyzers or support equipment. The accuracy and/or validity of data obtained from any analyzer depends upon analyzer performance and operator proficiency. Deviations from the recommended procedures set fort...

This report provides a pragmatic guide to the use of low-cost sensors, based on applied research and field experience, including the identification of monitoring objectives and the questions for which LCSs can be used, technical specifications, and quality assurance/quality control. This report focuses on the use of low cost sensors (LCS) for the measurement of the mass concentration of PM2.5, the...

Migration to cities creates densely populated environments and associated infrastructure. This results in increasing vulnerabilities and exposure to natural and anthropogenic hazards. In 2015, under Transforming our World: the 2030 Agenda for Sustainable Development, the United Nations identified “sustainable cities and communities” as one of its 17 Sustainable Development Goals. This Guidance ser...

On this page, you will find online learning modules on the basics of Atmospheric Composition. These modules are designed to help you, as a forecaster, learn the fundamentals of Atmospheric Composition. The modules will guide you in selecting and using global products from satellites, networks and numerical models throughout the lifecycle of extreme events....
