The government needs to tackle incoherent policy making if it is to meet its net zero target.
This report highlights a series of decisions where ministers seem to have undermined their own climate objectives, including on the Cumbria coal mine, roadbuilding, cutting air passenger duty on domestic flights, and boosting UK oil and gas production.
Several organisations have called for a “net zero test” to ensure ministerial decisions are compatible with the long-term climate commitment. But this report, which examines the experience of using policy tests in other areas like equality, argues that while such a test could be helpful it would not be sufficient to prevent ministers rationalising away decisions that seem to undermine wider government objectives.
It recommends how the government could develop a useable and useful net zero test – starting on a voluntary basis to aid to policy development and, if it proves useful, becoming a statutory duty over time. But it also argues that the government should follow up its proposals on “embedding net zero” across Whitehall departments, and calls on ministers to urgently publish the emissions reductions they expect to achieve through particular policies. This will be vital to proper scrutiny and keeping departments on track.
The report also calls on the government to:
- ensure that any policy decision with a significant impact on its ability to stick to the net zero pathway is subject to collective cabinet committee decision making
- produce assessments alongside budgets and spending reviews of the impact on its ability to deliver the net zero target
- consider creating a new independent function or body charged with forecasting the emissions impact of policies and other changes in the economy. This could sit between the OBR and the Climate Change Committee, following a model used in Denmark.
