GHG Management Hierarchy updated for net-zero

In December, IEMA published an update to its widely used GHG Management Hierarchy.

The Hierarchy was first published in 2009, with a focus on tackling significant and 'at-source' carbon emissions and avoiding jumping straight to a carbon offset solution. The updated hierarchy and briefing paper maintains this focus, but also recognises that the climate emergency now requires an escalation of action (across all hierarchy levels and varying with context).

The briefing includes new diagrams and descriptions, and considers the use of ambitious targets such as net-zero. Approaches, information sources and principles for practice are outlined. Informed by direct practice review and complementing a range of wider developments, the 2020 briefing and Hierarchy update is available now to support net-zero transition planning.
