The paper collects comprehensive and detailed data on what 40 OECD and G20 economies do with the revenues from carbon taxes, emissions trading systems, and excise taxes on energy use. It notes that constraints – which can take the form of political commitments or legal earmarks – on revenue...

The risks of carbon leakage associated with climate policies in the agricultural sector remains under-researched. Studies to date suggest that carbon pricing policies implemented by a single country, or small group of countries, reduce global emissions but also affect the international...

Carbon leakage arises when emission reductions in countries applying a carbon tax are offset, partially or completely, by emission increases in countries that do not apply the tax or any other greenhouse gas (GHG) mitigation policies. Analysis using the MAGNET computable general equilibrium...

This paper presents the potential benefits and challenges of enhanced international co-ordination on carbon pricing and outlines the different types and levels of co-ordination that are available for national and sub-national governments. These levels include, inter alia, facilitating new...

There are major gaps in the measurement of the adoption and stringency of countries’ climate actions and policies, notably in a manner coherent across countries, time, sectors and instrument types. The climate actions and policies measurement framework (CAPMF) aims to fill this gap. It is a...

We propose and implement a procedure to optimally hedge climate change risk. First, we construct climate risk indices through textual analysis of newspapers. Second, we present a new approach to compute factor mimicking portfolios to build climate risk hedge portfolios. The new mimicking...

Dynamic programming is the essential tool in dynamic economic analysis. Problems such as portfolio allocation for individuals and optimal economic growth are typical examples. Numerical methods typically approximate the value function. Recent work has focused on making numerical methods more...

We propose a new methodology to build portfolios that hedge the economic and financial risks from climate change. Our quantity-based approach exploits information on how mutual fund managers trade in response to idiosyncratic changes in their climate risk beliefs. We exploit two types of...

Public financial institutions (PFIs) are well-positioned to act as a key leverage point for governments’ efforts to mobilise private investment in low-carbon projects and infrastructure. The study identifies the tools, instruments and approaches used by five PFIs to directly support and...
