TEEMP is a suite of excel-based, free-of-charge, suite of spreadsheet models and methods that can be used to evaluate the greenhouse gas (GHG), air pollution, and other impacts of many types of transportation projects. The TEEMP tools were initially developed by the Clean Air Initiative for Asian Cities (CAI-Asia) and Institute for Transportation and Development Policy (ITDP) for evaluating the em...

The report by the Programme Coordinating Centre of the International Cooperative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests) details recent findings on the impact of air pollution on European forests. Despite significant changes since the 1980s, air pollution, particularly nitrogen deposition and tropospheric ozone, continues to affect forest ecosystems...

The report begins with a general overview of the basics behind the nature and science of visibility. Included in this section is a discussion on what causes visibility impairment, how visibility is impaired, how humans perceive visibility impairment, and how it is measured. The second section presents both historical trends on national visibility and examples of visibility degradation at specific ...

Natural capital accounting provides a way to integrate the value of ecosystem services into national economic reporting systems and is increasingly being adopted around the world. In this National Ecosystem Services Partnership (NESP) webinar, hear from Ken Bagstad (USGS), Scott Wentland (BEA), Mehdi Heris (Hunter College), and Katie Warnell (Duke University) about pilot natural capital accounts f...

The System of Environmental-Economic Accounting—Ecosystem Accounting (SEEA EA) is a spatiallybased, integrated statistical framework for organizing biophysical information about ecosystems, measuring ecosystem services, tracking changes in ecosystem extent and condition, valuing ecosystem services and assets and linking this information to measures of economic and human activity. It was developed ...

The Addis Ababa Principles and Guidelines for the Sustainable Use of Biodiversity provide a framework for assisting Governments, indigenous and local communities, resource managers, the private sector and other stakeholders, about how to ensure that their uses of biological diversity will not lead to its long-term decline.

Tourism may have important positive and negative economic, socio-cultural and environmental impacts. However, cultural and natural resources are also the base to the development of competitive destinations and changes in these resources can have an important impact on tourism development. Despite the considerable literature regarding the impacts of tourism, a limited number of studies examine the ...

Chapter 4 of the UNEP Frontiers 2018/19 report, titled "The Nitrogen Fix: From Nitrogen Cycle Pollution to Nitrogen Circular Economy," discusses the widespread issue of nitrogen pollution and its significant impact on the environment and human health. The chapter emphasizes the need to transform nitrogen management from a linear to a circular economy to mitigate these effects. It highlights the im...

At its fortieth session (18 December 2020), the Executive Body for the Convention on Long-range Transboundary Air Pollution adopted a guidance document on integrated sustainable nitrogen management (ECE/EB.AIR/146, annex I, decision 2020/1). The current document contains the guidance document as adopted. The purpose of the document is to mobilize Parties’ efforts to control pollution from agricult...

The aim of this trend report is to assess the effectiveness of air pollution policies under the UNECE Convention on Long-range Transboundary Air Pollution, and to document progress and identify remaining challenges. Trends in environmental and health responses to long-range transported air pollution are presented, primarily focusing on 1990 to 2012 and on Europe, with additional data from North Am...
