Expert viewpoints

One of the challenges in tackling a long-term fundamental issue like climate change is to ensure that the approach taken is “fair” between current and future generations. To help us think about this we commissioned Frontier Economics on a pro bono basis to provide a framework for analysing the issue of intergenerational equity.

This Viewpoint summarises the key messages from that work as we see them, provides some of our own reflections building on the Frontier report and highlights where further work is required.


The last year has seen a significant amount of CMA activity in the water and energy sectors.  This Viewpoint explores the differences in the appeals regime in these sectors, the basis for the recent appeals and their implications for purposeful regulation.  To address the challenges of net-zero and to facilitate the purposeful agenda, the appeals regime needs reform. 

To help reduce the focus on legal processes, and increase transparency and trust, this paper makes three suggestions for how the regime could be improved in terms of: cost of capital; social and environmental initiatives; and major investments and efficiency.


Sulphur Hexafluoride (SF6) is a man-made greenhouse gas with a warming potential 23,000 times that of carbon-dioxide. Long-lived and potent, it is widely used as an effective insulator in electricity substation switch-gear and circuit breakers. Equipment containing SF6 is found at every network voltage. Also in wind-turbine circuit breakers.
