List Custom Emission Groups

Retrieve all custom emission groups for your organization with pagination support. This endpoint returns groups without their associated emission factors.

To get groups with their emission factors included, use the Organization Data endpoint instead.

Example

curl "https://api.dcycle.io/api/v1/custom_emission_groups?page=1&size=50" \
  -H "Authorization: Bearer ${DCYCLE_API_KEY}" \
  -H "x-organization-id: ${DCYCLE_ORG_ID}" \
  -H "x-user-id: ${DCYCLE_USER_ID}"

import requests
import os

headers = {
    "Authorization": f"Bearer {os.getenv('DCYCLE_API_KEY')}",
    "x-organization-id": os.getenv("DCYCLE_ORG_ID"),
    "x-user-id": os.getenv("DCYCLE_USER_ID")
}

response = requests.get(

    headers=headers,
    params={"page": 1, "size": 50}
)

print(f"Total groups: {data['total']}")

for group in data['items']:
    print(f"- {group['name']} ({group['category']})")

const axios = require('axios');

  console.log(`Total groups: ${data.total}`);

  data.items.forEach(group => {
    console.log(`- ${group.name} (${group.category})`);
  });
})
.catch(error => console.error(error));

Use Cases

List All Groups

Get overview of all custom emission groups:

groups = requests.get(
    "https://api.dcycle.io/api/v1/custom_emission_groups",
    headers=headers,
    params={"page": 1, "size": 100}
).json()

print(f"Found {groups['total']} custom emission groups:\n")

for group in groups['items']:
    ghg_type_name = {1: 'Fossil', 2: 'Biogenic', 3: 'Mixed'}[group['ghg_type']]
    print(f"[{group['category'].upper()}] {group['name']}")
    print(f"  GHG Type: {ghg_type_name}")
    print(f"  ID: {group['id']}\n")

Filter by Category

List only groups of a specific category:

all_groups = requests.get(
    "https://api.dcycle.io/api/v1/custom_emission_groups",
    headers=headers,
    params={"page": 1, "size": 100}
).json()

# Filter for purchases only
purchase_groups = [g for g in all_groups['items'] if g['category'] == 'purchases']

print(f"Purchase groups: {len(purchase_groups)}")
for group in purchase_groups:
    print(f"- {group['name']}")

For server-side category filtering, use the List by Category endpoint instead.

Display in UI

Create a dropdown selector for groups:

async function loadGroupSelector(category) {
  const response = await axios.get(
    'https://api.dcycle.io/api/v1/custom_emission_groups',
    {
      headers,
      params: { page: 1, size: 100 }
    }
  );

  const groups = response.data.items
    .filter(g => g.category === category)
    .map(g => ({
      value: g.id,
      label: g.name,
      description: g.description
    }));

  return groups;
}

// Usage
const purchaseGroups = await loadGroupSelector('purchases');

Pagination Example

Handle large numbers of groups:

def get_all_groups(headers):
    all_groups = []
    page = 1

    while True:
        response = requests.get(
            "https://api.dcycle.io/api/v1/custom_emission_groups",
            headers=headers,
            params={"page": page, "size": 100}
        ).json()

        all_groups.extend(response['items'])

        # Check if we've retrieved all groups
        if len(all_groups) >= response['total']:
            break

        page += 1

    return all_groups

groups = get_all_groups(headers)
print(f"Retrieved {len(groups)} groups across all pages")
