Climate Change and Environmental Risks

Title

A Financial Approach to Environmental Risk

Summary:

There is increasing public pressure on governments to commit to credible plans to reduce greenhouse gas emissions through carbon taxes, cap and trade or other regulatory systems. The responses of governments to climate change will have large impacts on the economy and on the profitability of key industries. Consequently, the financial sector has an interest in encouraging the adoption of the most cost effective policies in order to minimize any negative impacts on economic growth.

This research exploits recent advancements in stochastic optimization, namely in multi-period Mean Variance (M-V) portfolio allocation theory, to develop a robust method to determine an investment strategy (climate change mitigation) to achieve a targeted level of real GDP per capita at a future specified time, at minimum risk. By using a GDP target, this method avoids having to choose an arbitrary discount rate and reflects the desired to leave future generations a reasonable standard of living. An efficient frontier showing various possible target levels for real GDP per capital and their associated risk will be produced, providing a clear illustration of the risk-return trade-off for climate change policies.
