Carbon APIs: connecting you and your customers to high-impact climate projects through easy-to-use technology

January 6, 2022


Addressing business carbon emissions by supporting impactful climate projects is a great way for companies to mitigate their unavoidable carbon footprint. One way to do so while also engaging customers is through the use of a carbon management API, which allows companies to measure, understand, and offset their carbon emissions and offer high-performance climate tech directly to their customers as well.

What is an API?

Here’s the technical part: an API, or application programming interface, is a set of rules and protocols that allows different software systems to communicate with each other. An API acts as an intermediary between different systems, allowing them to exchange data and functionality.

What does that mean? Let’s use an example from CHOOOSE to explain. Imagine a global airline which wants to offer its customers the ability to offset the carbon emissions associated with a flight. CHOOOSE builds technology that helps global businesses understand and address their emissions and that of their customers.

CHOOOSE’s API connects the airline’s systems with CHOOOSE carbon technology which calculates emissions and connects users with a wide range of climate projects, including carbon removal, community projects, and Sustainable Aviation Fuel. The airline can then use the API to purchase offsets and track the progress of its sustainability goals and impact achieved through a dedicated platform.

Who uses carbon offset APIs?

There are a variety of organizations that may be interested in using carbon offsetting APIs, including:

  1. Transportation and logistic companies such as shipping companies may want to use climate technology to track and offset the carbon emissions from their fleet, or offer it to its customers through a corporate program.
  2. Airlines can benefit from climate tech API by addressing their own emissions and also engaging their customers to address the emissions of their flights.
  3. Hospitality companies such as travel agencies and hotels can use climate technology to track and address the emissions from their operations while supporting sustainability in the tourism sector.

Using a carbon offset API is a convenient and effective way for companies to offset their carbon emissions and reduce their environmental impact. It allows them to easily calculate and offset their carbon emissions through a simple and convenient interface, without having to spend time and resources on calculating emissions, researching and selecting the highest quality offset projects, or manually tracking progress toward company-wide carbon reduction goals.

What projects can you support through a carbon API?

There are a variety of carbon offset projects available through a carbon offset API, including projects that focus on renewable energy, energy efficiency, sustainable aviation fuel, and reforestation. By funding these projects, companies and individuals can offset their carbon emissions and contribute to the fight against climate change.
