The aim of this present document is to provide Parties to the United Nations Economic Commission for Europe (UNECE) Convention on Longrange Transboundary Air Pollution with guidance in identifying the best abatement options for mobile emission sources, with particular reference to the Best Available Technique (BAT), in order to assist them in meeting the obligations of the 1999 Protocol to Abate A...

The guidance document outlines control techniques for emissions of sulphur, nitrogen oxides, volatile organic compounds, and particulate matter from stationary sources. It provides comprehensive guidelines on best available techniques for reducing emissions and improving air quality. The document aims to provide support to Parties to the UNECE Convention on Long-range Transboundary Air Pollution (...

At its thirty-first session (Geneva, 11–13 December 2012), the Executive Body to the Convention on Long-range Transboundary Air Pollution adopted a guidance document on economic instruments to reduce emissions of regional air pollutants to the 1999 Protocol to Abate Acidification, Eutrophication and Ground-level Ozone (Gothenburg Protocol), and decided that it would be the guidance document referr...

At its thirty-first session (Geneva, 11–13 December 2012), the Executive Body to the Convention on Long-range Transboundary Air Pollution adopted a guidance document on national nitrogen budgets which corresponds to the the guidance document referred to in article 7, paragraph 3 (d), of the 1999 Gothenburg Protocol to Abate Acidification, Eutrophication and Ground-level Ozone, as amended (ECE/EB.A...

"At its thirty-first session (Geneva, 11–13 December 2012), the Executive Body to the Convention on Long-range Transboundary Air Pollution adopted a guidance document on preventing and abating ammonia emissions from agricultural sources, and decided that it would be the guidance document referred to in article 3, paragraph 8 (b), and paragraph 6, annex IX, to the of the 1999 Protocol to Abate Acid...

With the success of policies to reduce SO2 and NOx emissions across the UNECE, ammonia (NH3) emissions remain a key challenge for the future. They are one of the largest contributors to acidification and eutrophication, while adding to the burden of particulate matter. As ammonia now offers ‘low-hanging fruit’ for further pollution control, combined with local and transboundary effects on health a...

The current document contains the report on best available techniques and practices as adopted by the Executive Body at its forty-first session (Geneva, 6–8 December 2021). The main objective of the document is to support Parties in reducing their emissions of air pollutants and short-lived climate pollutants (in particular, black carbon) – drivers of climate change emitted as a result of agricult...

The UNECE Code of Good Practice for wood-burning and small combustion installations provides guidelines to improve efficiency and reduce emissions from domestic wood heating. It includes an overview of existing guidance documents, key considerations, and recommended best practices for cleaner and more efficient wood-burning techniques. The guidance is particularly relevant for countries in Eastern...

At its thirty-first session, the Executive Body to the Convention on Long-range Transboundary Air Pollution adopted decisions amending the Protocol on Heavy Metals and its annexes (ECE/EB.AIR/113/Add.1, decisions 2012/5 and 2012/6), and adopted a guidance document on best available techniques for controlling emissions of heavy metals and their compounds from the source categories listed in annex I...

The purpose of this document is to provide guidance to the Parties to the Convention in identifying control options and best available techniques for reducing emissions of persistent organic pollutants (POPs) from major stationary sources with a view to implementing the obligations of the Protocol on POPs. The document describes control techniques for reducing emissions of dioxins and furans (PCDD...
