This project's mission is to make climate investing actionable. It includes both open source software and a free book to help you identify relative value trades, optimize portfolios, and structure benchmarks for climate aligned investing.

The Software

The software is a multi-factor equity returns model which adds a climate factor, or Brown Minus Green, to the popular Fama French and Carhart models. See the short video

This additional Brown Minus Green (BMG) return factor could be used for a variety of climate investing applications, including:

Setting It Up

Install the required python modules (use pip3 instead of pip according to your python installation):

pip install -r requirements.txt

Initialize the Database using:

python3 scripts/setup_db.py -R -d

Trying It Out

Let's get the historical stock prices and returns of the MSCI World Index and its constituent sectors:

python scripts/get_stocks.py -f data/msci_etf_sector_mapping.csv 
python scripts/get_stocks.py -f data/msci_constituent_details.csv

Now let's calculate the risk factor loadings for these stocks using 60 months of monthly data at a time:

python scripts/get_regressions.py -d -f data/msci_etf_sector_mapping.csv -s 2010-01-01 -e 2021-01-31 --frequency MONTHLY -n DEFAULT -i 60 -b
python scripts/get_regressions.py -d -f data/msci_constituent_details.csv -s 2010-01-01 -e 2021-01-31 --frequency MONTHLY -n DEFAULT -i 60 -b

Next, let's create a daily version of the BMG climate risk series based on the difference between the stocks XOP (brown) and SMOG (green):

python scripts/bmg_series.py -n XOP-SMOG -b XOP -g SMOG -s 2018-01-01 -e 2022-02-01 --frequency DAILY

Finally, let's calculate the risk factor loadings for stocks using 2 years of daily data. This will take a long time:

python3 scripts/get_regressions.py -d -f data/msci_etf_sector_mapping.csv -s 2018-01-01 -e 2021-01-31 --frequency DAILY -i 730 -n XOP-SMOG -b
python3 scripts/get_regressions.py -d -f data/msci_constituent_details.csv -s 2018-01-01 -e 2021-01-31 --frequency DAILY -i 703 -n XOP-SMOG -b
