Indicator 77. Availability and implementation of a transparent and detailed deep decarbonization strategy, consistent with the 2°C – or below – global carbon budget, and with GHG emission targets for 2020, 2030 and 2050.

Rationale and definition:

Keeping global warming within 2°C or less requires that countries prepare national deep decarbonization strategies to 2050, covering all sources of GHG emissions including from energy, industry, agriculture, forest, transport, building, and other sectors. These strategies should be transparent and detail how countries intend to achieve deep emissions cuts (including for energy- related emissions), how to reduce energy consumption, decarbonize the power sector, and electrify energy uses (in particular in the transport and building sectors). They should include targets to reduce GHG emissions by 2020, 2030 and 2050. This indicator also proposes to measure the implementation of such a strategy.


Opportunities for disaggregation to be reviewed.

Comments and limitations:

To be reviewed.

Preliminary assessment of current data availability by Friends of the Chair:
