What does it mean for corporate emission reduction target setting?

What is the SDA methodology? The Sectoral Decarbonisation Approach (SDA) is a freely available methodology that allows companies to set emission reduction targets in line with a 2ºC decarbonisation scenario. It is based on the 2ºC scenario (2DS) developed by the International Energy Agency (IEA) as part of its publication, Energy Technology Perspectives 2014 (IEA, 2014).

About the SDA methodology:

1. What

was the development process?

2. How does it work?
3. What are the limitations / areas for

development?

4. What about other methodologies?

SDA Methodology – Areas for further development

Areas for further development

Regional differentiation
E.g. Annex 1 vs. Non-Annex 1
Inclusion of structural parameters in key sectors
E.g. Primary vs. Secondary Aluminium
Scope 3 – Science-Based Target Setting
More in-depth analysis for additional sectors
Inclusion of LULUCF-related emissions
Inclusion of non-CO2 gases
