1 Green Economy Viele Konzepte... Welches Leitbild ist zukunftsfähig Dirk Messner Schwerte, März 2012

2 - Green growth (GGGI, Weltbank) - Green development (UNEP, UNDP) - Nachhaltige Entwicklung - Neue Wohlfahrtskonzepte - Große Transformation im Anthropozän - Gerechtigkeit, Fairness, Armutsbekämpfung stellt sich stellt sich nicht von allein ein - Armutsbekämpfung ohne grün geht nicht

3 Why a global low carbon transformation? We simply can`t scale up the existing growth patterns (Michael Spence) 9 billion people in 2050 Global GDP of 60 trillion US % (2010) 180 trillion US $ 2030/40 Growing global middle classes Impacts of dangerous climate change are well known 750 Gt Budget Planetary boundaries

7 Seit Ende des 20./ Beginn des 21. Jahrhunderts: Mensch als dominierende Kraft im Erdsystem (Paul Crutzen) Herausforderungen: - Erdsystemverantwortung neues Weltbild (Faktor X > Globalisierung gestalten) - Zeitskalen (lebende Generationen, zukünftige Generationen, Zeitskalen des Erdsystems) - 9 Mrd. Menschen, Weltbürgergesellschaft, wechselseitige Verwundbarkeiten, Wohlstand im Anthropozän

8 R. Fogel (1992): technophysio evolution Die dritte große Transformation Neue Globalisierung Machtverschiebungen/ post westliche Ordnung Anthropozän 1785: Dampfmaschine/ Spinnmaschine 1859: erste kommerzielle Ölbohrung 1880: fossile Energieträger überholen Biomasse 9

9 Drivers of transformations learning from the past Vision : better future, normative perspectives Abolition of slavery, European Union Technology : Rapid diffusion of innovations IT-revolution Knowledge : research driven, precautionary principle Protection of the ozone layers Crisis Structural adjustment programmes, financial market reforms after 2008

10 Where do we stand? Five good news five major challenges Technology assessment Costs Policy options Dynamics of the transformation

11 What needs to be transformed? Three transformation areas: basic structures of the global economy Energy Urbanization Land use

13 It`s about scale and speed! 6 Celsius path 2 Celsius path - 85/ 15 15/85 (30 % RE by 2030) - energy efficiency and carbon efficiency need to raise drastically (40 % by 2030) - stabilize energy consumption: EJ (2010: 390 EJ) #14

19 Long term costs Key problem: upfront investments... savings later Costs for climate damages not involved Global subsidies for fossil energy ca. 0,7 %-1,5 % of the global GDP Increase the investment ratio Structure of investments (globally) 20 % energy infrastructure 50 % buildings/ transport/ mobility 15 % low carbon R&D 15 % land use, industrial sectors

22 Managing the Transformation Trajectory Source: based on Grin et al., 2010 Since the 1970s: we do have a problem : Limits to Growth Rio 1992 Driving the transformation scale: from pilots to systems acceleration setting the course: long-term perspectives towards 2050 (roadmaps) from sector to system reforms (cities, mobility, energy, lifestyle) Building a low carbon society beyond policy reforms

24 Co-evolution: Transformation driven by the accumulation of multiple dynamics Growing number of actors of change II. Vision: low carbon narrative Shifting norms values / heuristics Policy regime Green innovation International context legitimacy concepts power it works (finance, technologies) I. Legitimacy of BAU eroding/ BAU no option/ Tipping point constellations Regime shifts can occur when the system is pushed across some threshold by external and internal dynamics. (Ostrom et al. 2008)... Tipping Point - Constellations

26 Co-Evolution, a social contract for sustainability. transformational policies mechanisms of change I. Legitimacy of BAU eroding Arenas and drivers of transformation: 1. New narrative 2. Actors 3. Innovation 4. Policy regime 5. International context 6. Shifting norms / values Social contract Transformational policies Co-evolution interaction between 1-6 mutual reinforcement from critical masses to accumulation of mutiple dynamics co-evolution strengthening low carbon: legitimacy concepts power alliances it works examples Low carbon becoming the main driving force / new mainstream II. Vision: low carbon narrative scaling up acceleration global diffusion of low carbon concepts

27 What can be done to make these drivers irreversible? Ten bunches of instruments 1 Proactive/ enabling state 2 Price for carbon 3 Regional energy cooperation 4 Internationalize feed in tariffs/ DESERTEC for Africa 5 Reduce energy poverty low carbon 6 Low carbon urbanization 7 Low carbon land use 8 Finance mechanisms and new business models polycentric strategy focused strategy 9 Low carbon research strategies/ knowledge gaps 10 Global governance for the low carbon transformation
