New inventions build on earlier inventions, so patent citations are one indication of who is standing on whose shoulders. We show that four low-carbon technologies (wind, solar, electric vehicles and batteries) exhibit markedly different patterns of citation behaviour. If technology spillovers are structurally different between sectors, this could imply that policies to support innovation clusters would need different approaches. Differentiated policies could range from promoting individual champions for technologies with strong internal spillovers, to supporting regional eco-systems for technologies with more fuzzy spillovers.
The objective of this brainstorm session is to explore how we can improve the quality and the impact of the revisited 2050 Roadmap, set the agenda for revising it, increase ownership of it and analyze the methodological basis of the 2050 Roadmap.
The effort to define rules for international emissions trading faces the strong desire of nation states to develop their own climate policies, which collides with the need for tradable units in one country to be equivalent to tradable units in another country. To overcome this dilemma Georg Zachmann proposes a club of carbon-buying countries that would regulate only imported mitigation outcomes.
China, the European Union (EU) and the United States (US) are responsible for the majority of global emissions of greenhouse gases, and produce about half of global GDP. Hence, their climate policies not only determine the success of global efforts to curb future emissions of greenhouse gases, but also affect policy developments in other countries. The aim of this report is to assist policy-makers, climate change negotiators and analysts to understand the domestic constraints and opportunities facing each jurisdiction, and to identify areas of common interest or concern between the three jurisdictions.

Decarbonisation and digitalisation are reshaping the European energy system, which will become more decentralised and interconnected with other sectors. Cities have the opportunity to be the key drivers of decarbonisation, but this will require the implementation of a new bottom-up governance system. This paper outlines a four-step mechanism in order to achieve decarbonisation at city level.
As the European Commission releases its new energy package, “Clean Energy for all Europeans”, our authors argue that cities are the key to success. They propose a new governance mechanism where cities develop and implement ambitious City Climate Plans – with direct monitoring and financial support from the EU.
Energy taxes contribute significantly to public budgets in the EU, but with the aim to reduce greenhouse emissions, the EU will have to fully decarbonise its energy system. However, taxing green energy poses a significant challenge, which could result in a tax revenue gap. Before this becomes a reality, European governments must start looking for alternative sources of public finance.
Cooperation in the energy sector could increase economic prosperity and political stability in North Africa and also generate economic opportunities for Europe. We propose a European public fund that would reduce the political risk for private sector investors in low-carbon energy in North Africa.
