Selecting appropriate greenhouse gas (GHG) emissions intensity metrics when evaluating the net impact of decarbonization solutions is critical. Learn how factors such as geographical location, electricity source, time of use, and more influence the choice of metric.

Transition planning is complex because it requires meeting increasing electricity demand with lower carbon intensity electricity sources while maintaining reliability and affordability. 

T&D capacity and curtailment primarily affect volumes, as opposed to net unit impact. In the example of a renewable energy source displacing a fossil fuel energy source, GHG impact should focus on where the solution and incumbent are different, including in downstream inefficiencies.

Until the grid reaches net zero, there's room for GHG impact if, for example, the intervention displaces fossil generation or has systemic effects (like accelerating coal retirement). Broader impacts may warrant adjustment factors in impact quantification. 

Electricity generation sources, like wind, solar, hydropower, geothermal, and fossil fuels (like coal and natural gas), and nuclear energy, differ in both how emissions are generated and how reliably they supply power. Read more for an overview of how these major generation sources compare, based on the geography of the US.

There are broadly 3 steps to creating and using electricity: generation, transmission, and distribution. This FAQ provides an overview of electricity generation, transmission, and distribution.

Frame’s growing library of emissions impact assessment case studies showcase our methodology in action. 

Through Investor Profiles, investors share their impact assessment approaches in a consistent way. While investors conform to Frame’s definition for GHG impact, we welcome them to share approaches to other forms of assessment that are not within Frame’s current scope of analysis, such as on other environmental, social, and governance topics.

Wondering how GHG impact is different from GHG footprinting? This article gives a comparison at a glance. 

A scope of analysis clearly defines what is and is not the focus of analysis. This worksheet helps investors clarify their own scopes as they communicate with investors and LPs regarding their methodologies.
