(Reuters) - Making a final assessment of the progress achieved over the two weeks of the COP26 talks in Glasgow will be complex. Unlike past climate summits, the event won't deliver a new treaty or one big "win".

Rather, it will attempt to produce a myriad of smaller victories - from the formal U.N. negotiations on the Paris Agreement, and from the new climate pledges that countries, companies and investors announce during the conference.
