What is a Deep Decarbonization Pathway?

0

A Deep Decarbonization Pathway (DDP) is term that describes a non-exclusive energy and economic transition scenario that meets a specific geography’s deep decarbonization target, typically an 80-95% reduction in annual carbon emissions by 2050 from the baseline 1990 level (see What is “Deep Decarbonization”? above).

USDDPP has created, and continues to update and explore, at least four DDPs at the national level, each of which emphasizes different investments, technologies and societal decisions. At the local, state or regional level, regulators, agencies and local stakeholders work together to create geographic-specific strategies that support the national target and are consistent with one or more viable national DPPs.

Each DDP must be based transparently on practical and realistic assumptions openly available for inspection and critique, and on viable technologies that either exist or can be reasonably assumed to exist in the appropriate time scale.
