Carbon Model: Capital Purchases b2b - how is CO2e allocated? #420

Closed chrisgovier closed 3 years ago

chrisgovier commented 4 years ago

When allocating CO2 from Capital Purchases (such as a Business installing Solar Panels), you are able to allocate the CO2e of purchase in one go, or discount over time. How is this included in the model? WRT bloom this could alter the suggestions of how to 'reduce' impact of operations. @martincollignon

Describe the solution you'd like A small 1-page document that states the assumptions used to make the model, and how it affects the outcome. There is not an industry best practice, for retail or hospitality therefore as long as the logic is stated it should be okay.

Describe alternatives you've considered CapEx for Businesses should be weighted at 30/30/30 for Y1-3 years after purchasing carbon-reducing/mitigating technologies.

This is an example of a Cost-Effective Analysis for Carbon Sequestration: https://www.mdpi.com/1996-1073/12/3/542/pdf Additional context Following on from @martincollignon discussion on 22/06/2020

Hi @chrisgovier ,

For now we are not having applying any discounting factor. It is a standard practice though. I will close this issue here as it doesn't affect the carbon models, but it will apply on top. It is something we will consider in Bloom in the future!

Best,

Olivier
