Greenhouse gas emissions attributable to products—from food to sneakers to appliances—make up more than 75% of global emissions. -The Carbon Catalogue
Our data, which is publicly availably on nature.com, contains product carbon footprints (PCFs) for various companies. PCFs are the greenhouse gas emissions attributable to a given product, measured in CO2 (carbon dioxide equivalent).
This data is stored in a PostgreSQL database containing one table, prouduct_emissions, which looks at PCFs by product as well as the stage of production these emissions occured in. Here's a snapshot of what product_emissions contains in each column:
product_emissions
product_emissions| field | data_type |
|---|---|
| id | VARCHAR |
| year | INT |
| product_name | VARCHAR |
| company | VARCHAR |
| country | VARCHAR |
| industry_group | VARCHAR |
| weight_kg | NUMERIC |
| carbon_footprint_pcf | NUMERIC |
| upstream_percent_total_pcf | VARCHAR |
| operations_percent_total_pcf | VARCHAR |
| downstream_percent_total_pcf | VARCHAR |
You'll use this data to examine the carbon footprint of each industry in the dataset!
SELECT industry_group AS industry_group,
COUNT(Industry_group) AS count_industry,
ROUND(SUM(carbon_footprint_pcf),1) AS total_industry_footprint
FROM product_emissions
WHERE year = 2017
GROUP BY 1
ORDER BY 3 DESC
