News from Carbon Standards International

Good day ,

There’s been plenty of exciting activity at Carbon Standards International in recent weeks – explore our latest highlights, insights, and new team members!

Publication of the Global Construction C-Sink Standard

The Global Construction C-Sink Standard verifies buildings and structures that incorporate carbon-storing materials (C-sink materials) derived from biomass.

Developed in collaboration with the Ithaka Institute for Carbon Strategies and OPENLY, the Construction C-Sink Standard can be broadly applied across the construction sector. All buildings that include biomass-based materials such as hemp, straw, biochar, and others can be certified as carbon sinks (C-sinks).

The first Carbon Sink according to the Global Construction C-Sink Standard has already been issued.

Visit from Taiwan

In recent days, a delegation from TCHAR Taiwan visited us in Switzerland to further strengthen our collaboration in carbon management. Their program included meetings in Frick, visits to Sonnenerde (Austria) and Energy Ocean (Switzerland), and a mountain hike above Kandersteg.

Calibration of Measurement Equipments for Global C-Sink Standards

On our website, you will now find a new category called “Principles and Requirements” under General Documents.

Here, we will publish documents that are relevant to all of our standards.
The first document in this category deals with the calibration of measurement equipments.

Monitoring data is used to calculate the size of a C-sink and the emissions produced during C-sink establishment. Some of this data is collected by the operators themselves using measuring equipments. It is essential that these measuring equipments are calibrated to ensure that they function correctly and that carbon sinks are calculated accurately. During on-site audits, the VVBs will verify that calibration of all measuring equipment was performed and documented.

Kind regards,

Your Team of Carbon Standards International AG
