Per capita carbon emissions are an important concept in international negotiations of climate policies and also in future projections of aggregate carbon emissions. This paper argues that the convergence studies on per capita carbon emissions in the literature are theoretically biased because...

Achieving a low-greenhouse gas (GHG) development requires making finance flows consistent with this objective. In order to measure progress to date as well as inform future public action in this area, this paper calls for further efforts to track gross primary investments flows in new...

Denmark’s green growth strategy focuses on moving the energy system away from fossil fuels and investing in green technologies, while limiting greenhouse gas (GHG) emissions. On the whole, current policies should allow Denmark to reach near-term climate change targets, but may not be...

Amidst other national and global climate protection initiatives, the new EU Commission under the leadership of Ursula von der Leyen is facing the challenge of concretely following through on previous announcements regarding an ambitious climate policy. Specifically, action must be taken to raise...

Countries have pledged to stabilize global warming at a 1.5 to 2°C increase. Either target requires reaching net zero emissions before the end of the century, which implies a major transformation of the economic system. This paper reviews the literature on how policymakers can design climate...

Climate change not only impacts production and market consumption, but also the relative scarcity of non-market goods, such as environmental amenities. We study fundamental drivers of the resulting relative price changes, their potential magnitude, and their implications for climate policy in...

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 UK has pledged to cut greenhouse gases 68 percent below 1990 levels by 2030, to be emissions neutral by 2050, and to phase out internal combustion engine vehicles by 2030. Much progress has been made, but fully achieving these ambitious objectives with the current policy framework will be...

To mitigate climate change, some governments opt for instruments focused on investment, like performance standards or feebates, instead of carbon prices. We compare these policies in a Ramsey model with clean and polluting capital, irreversible investment and a climate constraint. Alternative...

There is a lot we know about climate change, but there is also a lot we don't know. Even if we knew how much CO2 will be emitted over the coming decades, we wouldn't know how much temperatures will rise as a result. And even if we could predict the extent of warming that will occur, we can say...
