The 2012 amendments to the Protocol to Abate Acidification, Eutrophication and Ground-level Ozone (Gothenburg Protocol) to the Convention on Long-range Transboundary Air Pollution not only introduce commitments for Parties to reduce emissions of volatile organic compounds (VOCs), but also mandatory emission limit values for different activities in annexes VI and XI to the Protocol and the establishment of solvent management plans for activities using solvents covered by annex VI. The present document provides guidelines to measure VOCs emissions, develop solvent management plans and calculate emissions. It corresponds to the requirement in annex VI to the amended Protocol that “methods of calculation will be reflected in the guidance adopted by the Executive Body”.
