How Energy API Empowers ESG Teams with Advanced Carbon Accounting Tools

Introduction

In today's rapidly evolving energy landscape, organizations are increasingly focused on Environmental, Social, and Governance (ESG) criteria. Accurate carbon accounting is essential for these teams to measure their environmental impact and make informed decisions. However, accessing reliable energy market data can be a daunting task. Many developers and data engineers face the challenge of scraping data from various government portals, each with its own format and update schedule. This not only consumes valuable time but also introduces the risk of errors and inconsistencies.

This is where Energy API comes into play. By providing a unified REST API that aggregates wholesale energy market data from trusted sources, Energy API empowers ESG teams with advanced carbon accounting tools. With a single, normalized JSON interface, developers can access a wealth of data without the pain of dealing with incompatible formats or unreliable sources.

Why Energy API

Energy API stands out in the crowded field of energy data providers for several reasons:

• Unified Data Access: Instead of navigating multiple sources like OMIE, ENTSO-E, and EIA, developers can access all necessary data through one API. This significantly reduces the time spent on data integration and allows teams to focus on analysis and decision-making.
• Comprehensive Coverage: With over 39 symbols across six commodity categories—electricity, natural gas, crude oil, coal, carbon allowances, and grid carbon intensity—Energy API provides a holistic view of the energy market. This breadth of data is crucial for ESG teams looking to assess their carbon footprint accurately.
• Consistent JSON Schema: Every endpoint returns data in a consistent JSON format, which simplifies the development process. Developers can ship features in hours rather than weeks, as they do not need to spend time transforming data from different formats.
• Real-Time and Historical Data: Energy API offers both real-time and historical data, enabling teams to perform trend analysis and make informed predictions about future energy prices and carbon emissions.

Quick Start

Getting started with Energy API is straightforward. The base URL for accessing the API is:

https://energy-api.com/api/v1

To make your first request, you will need to include your API key as a query parameter. Here’s an example of how to fetch the latest prices for Brent Crude and TTF Gas:

curl -G https://energy-api.com/api/v1/latest \
--data-urlencode "symbols=BRENT_CRUDE,TTF_GAS" \
--data-urlencode "api_key=YOUR_API_KEY"

The expected JSON response will look like this:

{
"success": true,
"date": "2026-06-11",
"base": "MIXED",
"rates": {
"BRENT_CRUDE": 74.82,
"TTF_GAS": 38.15
},
"dates": {

"TTF_GAS": "2026-06-11"
},
"currencies": {
"BRENT_CRUDE": "USD",
"TTF_GAS": "EUR"
}
}

In this response, the key fields are:

• success: Indicates whether the request was successful.
• date: The date of the data retrieved.
• rates: Contains the latest prices for the requested symbols.
• currencies: Specifies the currency for each symbol.

Core Endpoints

Energy API offers a variety of endpoints that cater to different data needs. Here are four core endpoints relevant to ESG teams:
