2b:null 2c:["$","title",null,{"children":"Climate Trace: Shipping Data | Earthrise | Observable"}] 31:T962,# Climate Trace: Shipping Data ## Metadata 2.41GB .csv file `asset-shipping.csv` ```bash ❯ wc -l asset-shipping.csv 11643105 asset-shipping.csv ``` 11,643,105 lines in the .csv and 27 columns for each row. ```bash ❯ csvcut -n asset-shipping.csv 1: start_date 2: end_date 3: asset_identifier 4: asset_name 5: iso3_country 6: location 7: type 8: capacity 9: capacity_factor 10: activity 11: CO2_emissions_factor 12: CH4_emissions_factor 13: N2O_emissions_factor 14: other_gas_emissions_factor 15: CO2_emissions 16: CH4_emissions 17: N2O_emissions 18: other_gas_emissions 19: total_CO2e_100yrGWP 20: total_CO2e_20yrGWP 21: other1 22: other2 23: other3 24: other4 25: other5 26: other6 27: other7 ``` We can convert this to a sqlite database for further analysis with datasette. Because our data is so large, we need to create a `settings.json`[^1] that lets queries take longer and return more rows. ```sql select distinct asset_identifier from [asset-shipping] ``` Which returns 48,112 unique ships. ## Data Analysis ### Which ship has the most emissions? ```sql SELECT asset_name, asset_identifier, iso3_country, SUM(CO2_emissions) AS CO2_emissions FROM [asset-shipping] GROUP BY asset_identifier ORDER BY CO2_emissions DESC LIMIT 10; ``` **Name**: Orient **Identifier**: 9061617 **Country**: RUS **CO2_emissions**: 69420075.10475922 ### Where does that ship travel? First we grab all the data we have available for that unique_identifier: ```sql select rowid, start_date, end_date, asset_identifier, asset_name, iso3_country, location, type, capacity, capacity_factor, activity, CO2_emissions_factor, CH4_emissions_factor, N2O_emissions_factor, other_gas_emissions_factor, CO2_emissions, CH4_emissions, N2O_emissions, other_gas_emissions, total_CO2e_100yrGWP, total_CO2e_20yrGWP, other1, other2, other3, other4, other5, other6, other7 from [asset-shipping] where "asset_identifier" = 9061617 ``` Each row has a `location` that looks like `Point((132.011448333333 43.0765933333333))` which is a latitude and longitude. We will need to combine these points into lines to see a ship's path. # Ship History & Emissions Visualization So lets turn our data and our newly-created aggregations into visualizations we can look at. Our goal is to find some recommendations for how to integrate this shipping data into a global map of emissions. 32:T62c,bubbleMap = { const container = yield htl.html`
