In accordance with Article 4, paragraph 19, of the Paris Agreement, all Parties should strive to formulate and communicate long-term low greenhouse gas emission development strategies, mindful of Article 2 taking into account their common but differentiated responsibilities and respective capabilities, in the light of different national circumstances.The CMA, by its decision 1/CMA5, paragraph 42, ...

Agenda 2063 was developed through an extensive consultative process involving various African stakeholders, including the youth, women, Civil Society Organizations, the Diaspora, African Think Tanks and Research Institutions, Government planners, Private Sector, the African media, inter-faith leaders, the Forum for Former African Heads of State and Government, African Islands States and others. In...

The 2016 Assessment Report clearly shows that the Convention has delivered demonstrable improvements in reducing acidification of the environment and the highest peak levels of ozone and photochemical smog, persistent organic pollutants and heavy metals and has begun to reduce particulate matter and atmospheric levels and deposition of nitrogen. It has proved flexible and dynamic in responding to ...

In order to guide the design of new air quality improvement policies in the Megalópolis region, locally generated and updated scientific information is required on changes in emission profiles resulting from new regulatory measures and technological improvements, changes in urban climate caused by increasing urbanization, and changes in the atmospheric physical and chemical processes under a chang...

Air quality has been gradually improving over the past 20 years but remains a major public health issue, accounting for 40,000 deaths each year in France. Closely linked to issues of energy consumption and climate change, it is one of the three pillars of the Local Climate, Air and Energy Plans (PCAET).To support local authorities in their efforts to improve air quality, Atmo France and the Accred...

This report describes a collaborative effort between the U.S. EPA, the South Carolina Department of Health and Environmental Control, and local community and business leaders in ten upstate South Carolina counties to develop and analyze a multi-pollutant, risk-based air quality management strategy. A primary goal was to identify and evaluate a local control strategy targeting emissions of ozone an...

The implementation of emission limit values may not always be sufficient to meet national emission reduction obligations or air quality targets. Additional actions, such as nontechnical measures, can supplement efforts at the national, subnational or local level. The present document, prepared by the Task Force on Integrated Assessment Modelling, discusses several options for non-technical measure...

Electrification with decarbonized electricity is a central strategy for carbon mitigation. End-use electrification can also reduce air pollutant emissions from the demand sectors, which brings public health co-benefits. Here authors focus on electrification strategies for China, a country committed to both reducing air pollution and peaking carbon emissions before 2030. Considering both coal-inten...

Rapid urbanization is a growing global concern that challenges sustainability in cities. Urban trees provide several ecosystem services, such as climate regulation, carbon sequestration, and air-pollution removal. Thesustainable benefits of these services imply the preservation of urban forests in developing countries, where trees are frequently removed and replaced by buildings and other infrastr...

Climate justice means putting equity and human rights at the core of decision-making and action on climate change.The concept has been widely used to refer to the unequal historical responsibility that countries and communities bear in relation to the climate crisis. It suggests that the countries, industries, businesses, and people that have become wealthy from emitting large amounts of greenhous...
