Our Methodology

How we determine climate impact

Data that measures a company's impact on climate change has been around for years — it just wasn't available in a way that's easy for you to use.


GreenPortfolio plugs this information into its proprietary calculation to score public companies and banks for climate impact.

Our methodology focuses on three categories

How the GreenPortfolio Score is unique

Climate First Approach

Our calculation focuses on understanding if a company is helping or hurting the planet, unlike ESG ratings which focus on risk mitigation instead of impact.


We provide you with the reasoning behind our score, along with explanations of any assumptions or estimates made along the way.


We’re not just covering investments. We also rate the banks and financial providers themselves so you can understand the impact of your savings account or credit card fees.


We map our scoring to your investments and accounts and generate your personal climate impact score.
