Our Week 1 Delegation returned to South Royalton, Vermont this weekend, just as our Week 2 Delegation arrived. While their two experiences will have many common denominators — plenaries and informal consultations, side events and shwag, SBI and SBSTA agenda items, ADP and its two worksteams, and the whole host of acronyms that inform the substance of the textual debate (for example, REDD+, LDM, CDM, IPR, GCF) — the mood in the halls is quite distinct. Starting today, COP19 moves into high level political mode, with ministers (of foreign affairs or environment) arriving from all/most of the COP and KP state parties for the negotiations. Today – right now – we’re kicking off the opening plenary with these new negotiators, with speeches by the Polish Prime Minister, Ban Ki-Moon, Figueres, and a very long list of state party ministers. (Note: U.S. Special Envoy for Climate Change,Todd Stern, is due to speak at tomorrow’s plenary.) The pace of the negotiations has increased, as everyone awaits signs each day of how these new actors’ increased discretion will shape the post-2020 agreement. As you can see from yesterday’s posts, this new group of VLS JD, MELP, and LLM students is off and running.
