The project "Global greenhouse gas emission pathways until 2050" (2015-2017) aimed to develop transformation scenarios and strategies that both limit global warming to 2°C and take into account a number of environmental and sustainability criteria, such as food security, air quality, protection of aquatic and terrestrial ecosystems as well as socio-economic targets. This report presents the main findings of this work. The report opens with an assessment of the requirements for limiting future global temperature rise to less than 2°C. It then explores to what extend current climate policies, and especially the Nationally Determined Contributions (NDCs) support or endanger the achievement of the non-climate specific UN sustainable development goals (SDGs) and from here specifically looks at the sustainability im pacts of two main climate protection measures, i.e. biomass production and electricity generation from renewables. The report concludes with an assessment of sustainability-oriented strategies using an integrated energy-economy-climate and land-use modelling framework and highlights the potential of comprehensive climate policy approaches that align climate protection with sustainable development goals.
