RT Report T1 Climate Commitments of Subnational Actors and Business: A Quantitative Assessment of their Emission Reduction Impact A1 United Nations Environment Programme, PB United Nations Environment Programme SN 978-92-807-3465-2 YR 2015 FD 2015 LK https://wedocs.unep.org/handle/20.500.11822/9618 UL https://wedocs.unep.org/handle/20.500.11822/9618 NO Initiatives which catalyse climate action are now recognised increasingly as playing an important role in mitigating greenhouse gas emissions (GHG) and bridging the global emissions gap. The number and range of these initiatives is growing rapidly. There are several open questions about these initiatives at a global scale, including what contribution they can make to closing the emissions gap, but also what makes a successful initiative and how can this be replicated and scaled up. This paper focuses on the first of these questions. DS UN Environment Document Repository RD Sep 18, 2026
