Making Climate Data Accessible Through APIs

The availability of environmental data via APIs (Application Programming Interfaces) is transforming how companies make sustainability decisions. APIs act as digital interfaces that make complex climate data accessible and usable. This enables companies of any size to access CO₂ emissions data, biodiversity information, and ESG metrics—without having to develop their own data infrastructure. But how do these interfaces actually work, and how can they be used in practice?

How Climate APIs Work

Climate APIs function like automated data pipelines, collecting information from various sources—including meteorological stations, satellites, and radar systems—and standardizing it into a unified format. This not only reduces the effort of manual data entry but also significantly improves data quality. Using standardized protocols such as REST and JSON, APIs communicate with servers and often deliver data in JSON or XML format. A major advantage is the reusability of these interfaces: they make integration into existing systems easier and optimize the use of transferred data. For a deeper dive into how APIs are shaping climate tech, see The Role of APIs in Climate Finance.

Practical Examples of API Usage

The practical application of climate APIs shows how companies can use this technology for sustainable goals. A notable example is the Carbon Measurement API, which launched in September 2024. This API helps banks support small and medium-sized enterprises (SMEs) in transitioning to net zero emissions. It enables green lending by providing a carbon accounting tool that seamlessly integrates into existing banking systems. A leading UK bank has partnered to offer its 19 million business customers carbon accounting and decarbonization services.

George Sandilands, VP of Carbon Accounting at Sage, describes the initiative’s goals as follows:

"Sage is on a mission to support businesses on their journey to sustainability. By fostering a more sustainable business environment and offering tailored green finance products, banks can better serve their SME customers. They now have the tools needed for accurate carbon reporting. This helps drive a greener economy and, in turn, reduces their financed emissions."

Beyond this, climate APIs offer numerous other possibilities: from real-time emissions monitoring and increasing supply chain transparency to regulatory compliance. Companies can retrieve specific data for certain regions or timeframes and convert it into manageable datasets. This is especially advantageous for smaller businesses, enabling them to make informed sustainability decisions. For more on practical API applications, see McKinsey's report on APIs and sustainability.

Common Challenges in Developing Green Micro-SaaS

Developing sustainable Micro-SaaS solutions comes with some unique hurdles. These can involve both technical and operational aspects and affect how effectively such tools can be used for climate protection. Here are three key challenges that need to be addressed.

Ensuring Data Accuracy and Reliability

One of the biggest issues is the lack of standardized methods for sustainability reporting. Without uniform frameworks, it’s difficult to compare data and ensure transparency. Many companies publish data that isn’t precise enough to measure real progress in sustainability performance. Reports often focus more on compliance than on actual impact. The International Sustainability Standards Board (ISSB) is working to harmonize global sustainability reporting standards, which may help address these challenges. Learn about ISSB.

A promising approach is Life Cycle Sustainability Assessment (LCSA). This method considers environmental, social, and economic aspects throughout the entire product lifecycle. With the introduction of the CSRD, the situation in the EU is expected to improve: instead of 11,700 companies, around 49,000 will soon be required to disclose non-financial information in their reports. However, to improve the quality and comparability of this data, joint efforts from companies, policymakers, and researchers are needed.

Optimizing the Energy Efficiency of AI Systems

Another challenge is the high energy consumption of AI models. The computing power required for AI is currently doubling about every 100 days. Current forecasts suggest that by 2028, the electricity consumption of AI systems could exceed Iceland’s total energy use in 2021. IEA on AI energy demand.

“It is essential that we align the progress of AI with the imperatives of sustainability.” – Beena Ammanath, Board Member, Centre for Trustworthy Technology

However, there are ways to reduce energy consumption. Shifting AI workloads to periods of lower energy demand—such as at night or during cooler seasons—can yield savings of 12–15%. The choice of programming language also matters: compiled languages like Go, Rust, or C/C++ are often more energy-efficient than interpreted languages like Python or JavaScript. Profiling tools can also help identify and optimize resource-intensive code sections. Nature on AI's carbon footprint.

Meeting Certification and Compliance Requirements

In addition to technical optimization, Green Micro-SaaS providers must also comply with strict regulatory requirements. The EU AI Act, for example, demands transparency and adherence to copyright laws for AI systems. High-impact systems must meet additional requirements, including model evaluations, risk assessments, incident reporting, cybersecurity measures, and energy efficiency reports. EU AI Act details.

Further EU regulations set specific standards: the EU Data Act governs fair access to IoT data, while the Cyber Resilience Act establishes cybersecurity standards across the EU. The CSRD requires large companies to provide detailed sustainability reports, and the EU Green Claims Directive sets clear criteria for environmental claims. Read more about the Green Claims Directive.

A successful compliance management example is Inventure, a financial services provider that received ISO27001 certification in 2023. The company also complies with GDPR, NIS2, anti-money laundering, and KYC regulations and is supervised by financial authorities in Finland, Sweden, and Norway.

“The ISO27001 certificate is proof of the quality of Greenstep’s policies, procedures, and processes.” – Anne Kulla, Partner & Head of Compliance
