We use a two-period model to investigate intertemporal effects of cost reductions in climate change mitigation technologies for the power sector. The effect of cost reductions for CCS depends on how carbon taxes are set. If there is no carbon tax in period 1, but an optimally set carbon tax in...

If governments cannot commit to future carbon tax rates, investments in greenhouse gas mitigation will be based on uncertain and/or wrong predictions about these tax rates. Predictions about future carbon tax rates are also important for decisions made by owners of nonrenewable carbon resources....

Global warming and the carbon cycle are a dynamic system with positive feedbacks. Fossil fuels are exhaustible resources. These two facts mean that innovation in clean energy technology, rather than mitigating global warming, can lead to a permanently higher temperature path. This paper explores...

This study uses a unique dataset of investment flows to analyse the role of two categories of public interventions (finance and policies) in mobilising flows of private climate finance worldwide and in the more specific context of flows to and in developing countries. The objectives are...

In order to help address climate finance-related information needs under the UNFCCC, this paper explores the extent to which currently-available secondary data make it possible to estimate private finance mobilised by developed countries for climate action in developing countries. This is done...

This paper explores the role of state-owned enterprises (SOEs) in the low-carbon transition in OECD and G20 countries. It tracks GHG emissions and energy investments by SOEs and analyses the impact of SOEs on investments in renewable electricity. A descriptive analysis of SOEs’ role in the...

The rapid and deep emissions reductions needed to keep global warming to 1.5°C rely critically on an immense scaling-up of investment in clean energy technologies. The cost of capital plays a key role in determining investment decisions and, when elevated, can pose a significant barrier to...

By reducing the demand for fossil fuels, climate policy can reduce scarcity rents for fossil resource owners. As mitigation policies ultimately aim to limit emissions, a new scarcity for “space” in the atmosphere to deposit emissions is created. The associated scarcity rent, or climate rent...
