This series is designed to make available to a wider readership selected studies on environmental issues related to climate change, country environmental performance, environmental-economic modelling, environmental innovation, environmental taxes and green investment. Now released: "Exploring potential data sources for estimating private climate finance".
The paper reviews a number of commercial and public data sources to examine their potential for increasing coverage and understanding of the volume and characteristics of private climate finance beyond renewable energy projects. Such information is needed to assess progress towards the global transition to low-carbon, climate-resilient economies.
This paper presents a framework to include feedbacks from climate impacts on the economy in integrated assessment models. The proposed framework uses a production function approach, which links climate impacts to key variables and parameters used in the specification of economic activity. The paper pays particular attention to the challenges of distinguishing between damages and the costs of adapting to climate change.
This document provides a detailed technical description of the ENV-Linkages model. The OECD ENV-Linkages Computable General Equilibrium (CGE) model is an economic model that describes how economic activities are inter-linked across several macroeconomic sectors and regions. It links economic activity to environmental pressure, specifically to emissions of greenhouse gases (GHGs).
In its 2012 edition of the World Energy Outlook, the International Energy Agency (IEA) produced an Efficient World Scenario to assess how implementing only economically viable energy efficiency measures would affect energy markets, investment and greenhouse emissions (GHG). Using the OECD ENV-Linkages macro-economic model, this report simulates the economic and environmental impacts which the IEA Efficient World Scenario implies.
Risk finance is essential for new ventures to commercialise new ideas and grow, especially in emerging sectors. Yet very little is known about the drivers and characteristics of risk finance in the green sector. This paper aims to fill this gap by providing a detailed description of risk finance in the green sector across 29 countries and identifying the role that policies might have in shaping high-growth investments.
This case study describes the approach taken to reduce NOx emissions from combustion plants, the challenges encountered and the social, environmental and economic impacts. It concludes by discussing the wider lessons that are raised for other governments seeking to develop similar policy responses.
Colombia has made progress towards eliminating fuel and diesel subsidies and reducing discretionary spaces allowing for artificially low fuel prices, but challenges remain. This paper discusses the political economy of fuel subsidies in the country to understand why reform has been so slow.
This paper examines how institutional investors can access green infrastructure, the extent to which this is currently happening, and the barriers to scaling up these investment flows. Based on four case studies, broader lessons are drawn for governments on the policy settings which may support investment in green infrastructure by institutional investors.
This paper reviews the political economy of the Canadian province of British Columbia (BC) tax in three periods: its origins, its survival in the face of political backlash, and its longer-term prospects. The BC launched North America’s first revenue-neutral carbon tax reform. The tax, applied to all combustion sources of fossil fuels, was introduced at a rate of CAD 10 per tonne of CO2.
