This road traffic Emissions Factors Toolkit (EFT) user guide has been compiled by Bureau Veritas in the role of Project Manager for the Local Air Quality Management (LAQM) Helpdesk and should be used in conjunction with Version 13.1 of the Toolkit.The EFT is published by Defra and the Devolved Administrations to assist local authorities in carrying out Review and Assessment of local air quality as...

This presentation is part of the Hands-on training Workshop on National GHG Inventory delivered by the Capacity-building Initiative for Transparency - Global Support Programme (CBIT-GSP). It covers the cross-cutting components of national greenhouse gas (GHG) inventory development, including institutional arrangements, data collection, and quality assurance/quality control (QA/QC). It outlines the...

The ICP Forests Monitoring Manual documents the harmonized methods for sampling and analysis as adopted by the participating countries of ICP Forests.Part I: Objectives, strategy and implementation of ICP ForestsPart II: Basic design principles for the ICP Forests monitoring networksPart III: Quality assurance within the ICP Forests monitoring programmePart IV: Visual assessment of crown condition...

The System of Environmental-Economic Accounting – Ecosystem Accounting (SEEA EA) is a spatially based, integrated statistical framework for organizing biophysical information on 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. SEEA EA was devel...

These data provide information on the amount of excess acid or nitrogen deposition above the critical load values set to protect acid- and nitrogen-sensitive habitats in the UK. The AAE has been calculated using UK Concentration Based Estimated Deposition (CBED) data for 2013-2021. The data resources consist of two files: (a) 1x1 km resolution Average Accumulated Exceedance (AAE) data summarising ...

This report provides key information to track the effects on ecosystems of policies aimed at meeting national and international air pollution targets, e.g. under the UK Government’s National Emission Ceilings Regulations (NECR) the Clean Air Strategy 2019 (CAS), and the United Nations-Economic Commission for Europe Convention on Long-range Transboundary Air Pollution (CLRTAP). It also provides the...

This report contains the scientific background to the review and revision of the empirical critical loads of nitrogen (CLempN) that had been established for Europe in 2011 under the UNECE Convention on Long-range Transboundary Air Pollution. This review uses for the first time gradient studies to evaluate and determine the ClempN. The results, as presented in Table 1 of the Executive Summary, show...

Acidification and eutrophication are common limnological stressors impacting many water bodies across the globe. While the negative impacts of these stressors on limnetic communities are generally known, their influence on the accumulation of specific sediment constituents, such as metals, remains unclear. Benefitting from past research and long-term monitoring, lakes at the International Institut...

Adverse effects of acidic deposition on the chemistry and fish communities were evident in Adirondack Mountain lakes during the 1980s and 1990s. Fish assemblages and water chemistry in 43 Adirondack Long-Term Monitoring (ALTM) lakes were sampled by the Adirondack Lakes Survey Corporation and the New York State Department of Environmental Conservation during three periods (1984–87, 1994–2005, and 2...

Rapid and drastic anthropogenic impacts are affecting global biogeochemical processes and driving biodiversity loss across Earth's ecosystems. In aquatic ecosystems, species distributions are shifting, abundances of many species have declined dramatically, and many are threatened with extinction. In addition to loss of diversity, the ecosystem functions, processes and services on which humans depe...
