This deliverable analyses transformation opportunities, barriers and policy options in about 10 countries for each of the four sectors energy-intensive industries, transport, buildings, and agriculture, forestry and other land use (AFOLU). The analysis shows that while there generally is the potential to achieve sufficient emission reductions to achieve the objectives of the Paris Agreement, mobilisation of this potential is impeded by strong barriers across all sectors. In addition, existing policies are nowhere nearly strong enough to overcome these barriers and mobilise mitigation opportunities. The sector reports contain options to strengthen policies for each target country as well as cross-country comparisons of results.
