Energy Investment Needs for Fulfilling the Paris Agreement and Achieving Sustainable Development Goals Keywan Riahi, International Institute for Applied Systems Analysis (IIASA) The World Bank, 27 November 2017, Washington DC, USA

New Paper on Future Investment Needs McCollum et al, submitted to Nature Energy Support by the World Bank and CD-LINKS. Multimodel Assessment 6 teams 1.5 and 2C scenarios NDCs vs SDGs

Paris Agreement + SDGs

GHG emissions (GtCO2e) Staying below 2C requires a deep and rapid transformation 100 80 early peak ~2020 NDCs 60 40 20 0 rapid decarbonisation electrification, efficiency(!) zero-c power sector net zero GHG emissions ~ 2070 2 C negative emissions in some scenarios -20 1950 1975 2000 2025 2050 2075 2100

GHG emissions (GtCO2e) 100 1.5C requires further acceleration and an even deeper transformation 80 NDCs 60 40 20 VERY rapid decarbonisation, demand! + supply Net zero GHG emissions ~ 2050 0 2 C 1.5 C -20 1950 1975 2000 2025 2050 2075 2100 Earlier and more negative emissions compared to 2 C

Low-Carbon Investment Shares 1.5C zero-carbon / renewables share ~80%

Regional Investments (2C) 2015-2050, compared to baseline Most of the investments in Asia due to growth & decarbonization OECD second, focus on capacity replacement McCollum et al, (under embargo do not cite or quote)

Regional Disinvestments (1.5C vs 2C) 2015-2050, compared to baseline Most of the disinvestments in fossil resource countries Middle East/Africa, Asia, OECD McCollum et al, (under embargo do not cite or quote)

Balancing Trade-offs Between Water and Energy Investments Integrated assessment of global energy and water infrastructure pathways Interactions between clean water (SDG6) and climate change mitigation through energy systems Global power sector costs are between 8 and 11 % higher when SDG6 added to 1.5 C SDG6 access and efficiency targets accelerate expansion of electricityintensive water sources SDG6 water efficiency targets limit water-intensive low-carbon energy technologies

Climate and Water Policy Interactions 2030 SDG Agenda Limited CCS / nuclear +4% more electricity demand Air-cooling technologies Water costs increasing under decarbonization SDG6 scenarios are the most vulnerable due to the prevalence of electricityintensive water infrastructure

Integration of global and national perspective Global transformation pathways Framing within global targets Boundary conditions, e.g. interntional feedbacks, techno-economics, resource prices National low-carbon development pathways Improved representation of national circumstances and policy priorities
