The Deep Decarbonization Pathways Project (DDPP), an initiative of the Sustainable Development Solutions Network (SDSN) and the Institute for Sustainable Development and International Relations (IDDRI), aims to demonstrate how countries can transform their energy systems by 2050 in order to...

This paper examines how changes in an international climate regime would affect the European decarbonization strategy and costs through the mechanisms of trade, technology, and innovation. We present the results from the Energy Modeling Forum (EMF) model comparison study on European climate...

After twenty years of global negotiations, the world is still far from a comprehensive climate agreement. The "top-down" approach embodied by the Kyoto Protocol has all but stalled, chiefly due to disagreements over levels of ambition and objections to financial transfers. To avoid those...

The Energy Modeling Forum 28 (EMF28) study systematically explores the energy system transition required to meet the European goal of reducing greenhouse gas (GHG) emissions by 80% by 2050. The 80% scenario is compared to a reference case that aims to achieve a 40% GHG reduction target. The...

This paper presents a novel way to disentangle inequality aversion over time from inequality aversion between regions in the computation of the Social Cost of Carbon. Our approach nests a standard efficiency based Social Cost of Carbon estimate and an equity weighted Social Cost of Carbon...

With the long term goal of holding the increase in the global average temperature to well below 2°C and "to pursue efforts to limit the temperature increase to 1.5°C", the Paris Agreement puts renewed attention on the portfolio of technologies needed to achieve consistent emission reductions...

The EU has a consolidated climate and energy regulation: it played a pioneering role by adopting a wide range of climate change policies and establishing the first regional Emission Trading Scheme (EU ETS). These policies, however, raise several concerns regarding both their environmental...

The COP-21 meeting in Paris produced an important result. For the first time all countries developed and developing agreed to take some mitigation action. However even if all countries deliver on what they have promised by 2030 and progress thereafter continues only at the same rate global...

While the international community has agreed on the long-term target of limiting global warming to no more than 2°C above pre-industrial levels, only a few concrete climate policies and measures to reduce greenhouse gas (GHG) emissions have been implemented. We use a set of three global...
