GTL speakers Assessing the Economic Impacts of Environmental Policies May 2021

On 17 May, OECD Chief Economist Laurence Boone presented evidence from a decade of OECD research and analysis, which looks at the relationship between environmental policies and economic outcomes such as employment, investment, trade and productivity. Over the years, governments have gradually adopted more rigorous environmental policies to tackle challenges associated with pressing environmental issues, such as climate change, air pollution, waste management or biodiversity loss. The ambition of these policies is, however, often tempered by their perceived negative effects on the economy.

In a world characterised by the rise in global value chains and capital flows, do differences in the stringency of environmental policies across countries alter firms’ competitiveness and cost jobs? Does taking the lead trigger a first-mover advantage? What are the differentiated impacts across firms, industries and regions? And are these policies effective in reducing emissions from industry?

We explored these questions in the context of the Covid-19 crisis and green recovery with insights on designing environmental policies to ensure the largest benefits and compensate workers and industries that may lose out. The presentation was followed by a panel discussion with guest speakers:

On 25 March 2021, Shunta Yamaguchi and Rob Dellink of the OECD Environment Directorate presented the role of international trade in the transition to a resource efficient and circular economy. The presentation highlighted findings from a series of recent OECD reports, including: The Consequences of a more resource efficient and circular economy for international trade patterns and International trade and circular economy: Policy alignment.

A circular economy aims to transform the current linear economy into a circular model to reduce consumption of finite material resources by recovering materials from waste streams for recycling or reuse, using products longer, and exploiting the potential of the sharing and services economy. Circular economy policies and initiatives largely take place domestically at the national or regional level. However, they have important interlinkages with international trade.

International trade plays an important role in circular supply chains in materials and products, end-of-life value chains in waste and scrap, secondary raw materials and second-hand goods. In this light, how can trade contribute to a more resource efficient and circular economy? How would the circular economy transition have an impact on global trade patterns? And in what ways can we secure coherence in these two policy areas?
