Air Quality Index (AQI) is information about atmospheric pollutants, which is essential for governments to inform the public about the current air quality and potential health risks. By analyzing the AQIs from 11 countries (regions), authors discovered considerable variations in the design of AQI information, which may open up room for unintended interpretation from the public. Therefore, as an at...

The UNEP Governing Council adopted the Bali Guidelines in 2010 to assist countries in filling gaps in national and sub-national legislation to facilitate broad access to information, public participation and access to justice in environmental matters. In 2012, UNEP and the United Nations Institute for Training and Research (UNITAR) joined hands to promote the Bali Guidelines, including through a p...

These guidelines by the Jamaican National Environment and Planning Agency (NEPA) cover public consultations for environmental impact assessments.There are two levels of public consultation involved in the Environmental Impact Assessment (EIA) process. The first is direct involvement of the affected public or community in public consultations during the EIA study. These consultations allow the deve...

The good practice recommendations aim to improve public participation in strategic environmental assessment (SEA) as provided for by the United Nations Economic Commission for Europe (ECE) Protocol on Strategic Environmental Assessment (Protocol on SEA) to the Convention on Environmental Impact Assessment in a Transboundary Context (Espoo Convention). Their objective is to support the application ...

The overall goal of public consultation is to engage key stakeholders’ groups such as citizens, NGOs, agencies, authorities and interest groups to provide their input into the planned development and especially on those impacts that directly or indirectly affect people’s livelihoods. Moreover, by involving key stakeholders’ inputs in the Environment Impact Assessment (EIA) the planned project is s...

Since 2016, London’s air quality has improved dramatically, and the number of Londoners living in areas that exceed the UK’s legal air pollution limits has decreased significantly. Drawing on data from London’s comprehensive monitoring network and the latest modelling from the London Atmospheric Emissions Inventory (LAEI), this report evaluates how air quality in London has improved between 2016 a...

The practice of participatory sensing for environment monitoring has rapidly evolved over the years. There has been a steady growth of citizen-based air quality monitoring projects that aim to build partnerships, knowledge-sharing platforms, awareness, and ultimately resilience to issues related to air quality. Whilst citizen science has reshaped air quality research by bringing a fresh perspectiv...

The Climate Action Aggregation Tool (CAAT) supports government experts, analysts and policymakers to identify, quantify and aggregate the impact of non-state and subnational actions. As a result, they can be integrated into mitigation targets, projections and scenarios in support of policy development, policy evaluation and target-setting.The tool distils the step-by-step process laid out in the I...

Introduction: Car-Free Days (CFDs) in Kigali, Rwanda, are held twice monthly on Sundays, when motorized vehicle traffic is restricted on major roads from 7:00 AM–11:00 AM to promote physical activity and reduce air pollution. Previous studies assessing the effectiveness of CFDs in reducing air pollution in Kigali have relied solely on short-term, low-cost fine particulate matter (PM2.5) measuremen...

The Personalised Real-Time Air Quality Informatics System for Exposure – Hong Kong (PRAISE-HK) is an advanced smart-city system developed by the Institute for the Environment, HKUST.This brochure, published by the Hong Kong University of Science and Technology (HKUST) Institute for the Environment, describes the mobile app which provides real-time and forecasted outdoor air-quality information at ...
