Unilateral measures and global emissions mitigation

In this paper we discuss global climate change mitigation that builds on existing unilateral actions to deliver ever deepening emission cuts over time. A wide array of unilateral environmental measures have been documented. We discuss the rationale for such measures and argue that unilateral initiatives have the potential to generate positive spillover e¤ects both within and across countries. Using a simple dynamic model of learning, we show how global negotiations can accelerate convergence to a global low emissions regime by building on and strengthening the positive spillovers inherent in unilateral initiatives

Unilateral Measures and Emissions Mitigation

We discuss global climate mitigation that builds on existing unilateral measures to cut emissions. We document and discuss the rationale for such unilateral measures argue that such measures have the potential to generate positive spillover effects both within and across countries. In a simple dynamic model of learning we show that while single countries on their own may never get to the point of switching completely to low emission activities, a learning process with positive spillovers across nations is more likely to deliver a global switch to low emissions. We discuss the key features of a new global Intellectual Property (IP) regime that builds on the positive spillovers inherent in unilateral initiatives and accelerates global convergence to low emissions.
