I've always believed that if you shut people in a room for long enough, they'll find something to agree on. A fiery debate maybe more fun, particularly over a drink with friends, but if it never reaches resolution it never actually achieves anything. Agreements can come naturally, but more often they don't -- in which case they require capitulation or compromise. Given that no one likes capitulation (unless it's by the other person) compromise has to be the norm. So it was at the COP21 in Paris.
The meeting is a key opportunity for international leaders to reach agreement on next steps: an agreement that should be ambitious, pushing us further along the path of emissions reductions; an agreement that is legally binding; and one which is supported by regular defined reviews to help tie us to our commitments.
UNAIDS has embraced the ambitious goal of ending the AIDS by 2030, and this has now been formally endorsed within the United Nation's Sustainable Development Goals agenda. On World AIDS Day, UNAIDS will be calling for the world to achieve: "Zero new HIV infections. Zero discrimination. Zero AIDS-related deaths."
