New Feature: Carbon Footprint Tracking for Transactions

We're excited to announce a new field in our enrichment API: co2_category. This feature helps users understand the environmental impact of their spending, enabling a new generation of sustainability-focused financial applications.

Why Carbon Tracking Matters

Climate change is one of the biggest challenges of our time, and consumers increasingly want to understand their personal impact. Studies show that:

• 73% of consumers are willing to change their habits to reduce environmental impact
• Personal spending accounts for over 60% of global greenhouse gas emissions
• Banking apps with sustainability features see 2x higher engagement

By adding carbon footprint data to transactions, you can help users make more informed decisions about their spending.

How It Works

Every transaction enriched through our API now includes a co2_category field with one of five values:

Example Response

{
  "merchant_name": "Shell",
  "category": "Gas & Fuel",
  "co2_category": "very_high",
  "is_chain": true,
  "confidence": 0.97
}

Use Cases

Here are some ways our customers are using carbon tracking (see more in our use cases page):

1. Carbon Footprint Dashboards

Show users their monthly carbon impact with visual breakdowns by category. Help them understand which spending habits have the biggest environmental impact.

2. Sustainability Challenges

Gamify sustainability by challenging users to reduce high-carbon spending. Offer rewards or badges for hitting targets.

3. Carbon Offsetting

Calculate the estimated CO2 from spending and offer users the option to offset through tree planting or renewable energy projects.

4. ESG Reporting

For corporate expense cards, aggregate carbon data across the organization for sustainability reporting and ESG compliance.

Building a Carbon Tracker

Check out our code examples for a complete implementation of a carbon footprint calculator using our API.

// Calculate carbon impact score
const CO2_WEIGHTS = {
  'very_low': 0.1,
  'low': 0.3,
  'medium': 0.5,
  'high': 0.8,
  'very_high': 1.0
};

const carbonScore = transactions.reduce((score, tx) => {
  return score + CO2_WEIGHTS[tx.co2_category];
}, 0) / transactions.length;

No Extra Cost

The co2_category field is included in all API responses at no additional cost. It's part of our affordable from $0.01 per request pricing.
