Use Cases

​
Annual Report

Generate the complete annual report for audits: 
def generate_annual_report(client, year):
    """Generate annual ISO 14083 report"""
    start_date = f"{year}-01-01"
    end_date = f"{year}-12-31"

    report = get_report(client, start_date, end_date)

    # Save report
    filename = f"report_{client}_{year}_ISO14083.json"
    with open(filename, 'w') as f:
        json.dump(report, f, indent=2)

    return report

# Example
annual_report = generate_annual_report("Correos Express", 2024)
print(f"Annual emissions: {annual_report['summary']['total_co2e']/1000:.2f} tons CO2e")

​
Monthly Comparison

Compare emissions month by month: 
import calendar

def monthly_comparison(client, year):
    """Compare emissions by month"""
    monthly_data = []

    for month in range(1, 13):
        # Calculate last day of month
        last_day = calendar.monthrange(year, month)[1]

        start_date = f"{year}-{month:02d}-01"
        end_date = f"{year}-{month:02d}-{last_day}"

        report = get_report(client, start_date, end_date)

        monthly_data.append({
            "month": calendar.month_name[month],
            "co2e": report['summary']['total_co2e'],
            "shipments": report['summary']['total_shipments']
        })

    return monthly_data

# Usage
comparison = monthly_comparison("Correos Express", 2024)
for month_data in comparison:
    print(f"{month_data['month']}: {month_data['co2e']:.2f} kg CO2e ({month_data['shipments']} shipments)")

​
Sustainability Dashboard

Extract KPIs for a dashboard: 
def get_sustainability_kpis(client, start_date, end_date):
    """Extract key KPIs for dashboard"""
    report = get_report(client, start_date, end_date)

    kpis = {
        "total_emissions_tons": report['summary']['total_co2e'] / 1000,
        "avg_emissions_per_shipment": report['summary']['avg_co2e_per_shipment'],
        "total_shipments": report['summary']['total_shipments'],
        "total_distance_km": report['summary']['total_distance'],
        "most_used_transport": max(
            report['by_transport_type'],
            key=lambda x: x['shipments']
        )['toc'],
        "greenest_transport": min(
            report['by_transport_type'],
            key=lambda x: x['co2e'] / x['shipments']
        )['toc']
    }

    return kpis

Common Errors

​
404 Not Found - Client Not Found

{
  "detail": "No data found for client 'Correos Express'",
  "code": "CLIENT_NOT_FOUND"
}
Cause: The client name doesn’t exist or has a typo Solution:

{
  "detail": "Invalid date format. Use YYYY-MM-DD",
  "code": "INVALID_DATE_FORMAT"
}
Solution: Use the YYYY-MM-DD format (for example: "2024-11-20")

​
400 Bad Request - Date Range Too Large

{
  "detail": "Date range cannot exceed 1 year",
  "code": "DATE_RANGE_TOO_LARGE"
}
Solution: Divide the period into smaller ranges (maximum 1 year per request)
