Sustainable Development Solutions Network: Leadership council meeting

The World in 2050 Project

The World in 2050 Project (TWI2050) will explore the implications of the necessary transformative sustainable development pathways and the possible ‘degrees of freedom’ to meet economic development goals within a safe operating space of a stable planet. This project will serve the global community with analyses of pathways the world (sectors, nations, communities) can take to attain these internationally agreed sustainable development goals within planetary boundaries, and to monitor progress and success towards their achievement.

It will enhance the understanding of the requirements of desirable and feasible sustainable development pathways. This will fill an urgent gap, of analyzing the options, feasibility and consequences (socially, economically and environmentally) of transitioning to pathways to sustainable development. The project will explore avenues to achieve sustainable development pathways, by back-casting from desired development outcomes as defined by the SDGs. The initiative will combine recent advancements in economic modeling and Earth system science to study the interactions between economic growth and global sustainability for sustainable development (SD) pathways. It will use existing global assessments and scenarios (e.g., the SDSN Deep Decarbonization Project) and integrated assessment models (e.g., MESSAGE, IMAGE, and IMPACT/ GLOBIOM/GAEZ) to evaluate the linked impacts of global food policy, ecosystem changes, climate change and energy use. The transformative pathways will serve to identify short-term actions for achieving sustainable futures and their co-benefits e.g. for health or security. Current trends as captured by business-as-usual (BAU) developments will help identify costs and damages of inaction. By integrating several world-class models in key sectors (energy, food, population, education, macroeconomics, biodiversity, climate, etc.) the project will produce paradigm-shifting narratives and scenarios that will significantly expand the capacity to carry out integrated assessments of critical pathways.

Importantly the project will examine the interactions among all the SDGs to explore the potential for co-benefits and/or trade-offs of addressing multiple SDGs at the same time, which can provide critical information for policy and investment decisions.  This will allow the project to generate the 1^st generation of global scenarios that meet the twin objectives of economic growth and planetary stability and thus provide improved evidence, including macro-economic assessments, to political leaders in the SDG process, and other key decision makers, on the feasibility, challenges and opportunities associated with meeting long-term development goals, i.e., development goals that are truly sustainable at a global scale.
