In 2003, the LRTAP convention established a special Trust Fund to facilitate the participation of countries with economies in transition (Decision 2003/11 of the Executive Body, ECE/EC.AIR/79 annex XI). Every year, the LRTAP Secretariat invites Parties to voluntarily contribute to the fund. The funds support the participation of enumerated countries with economies in transition to participate in “meetings of the Executive Body and its three main subsidiary bodies, giving highest priority to negotiating groups and other meetings directly linked to preparatory or ongoing negotiations.” Additionally, Albania, Tajikistan, Turkmenistan, and Uzbekistan can qualify for the funding “upon their accession to the Convention and their expressed intention to take part in the work of the Executive Body ….”
