Carbonhound & Blue Sky Climate Reporting Services
California’s new climate laws, SB 253 (emissions reporting) and SB 261 (climate-related risk disclosure), have many businesses asking: Where do we begin?
To help answer that question, Carbonhound is working alongside Blue Sky Climate Reporting Services, a California-based climate reporting consultancy with global reach. While we operate independently, we share a vision: to make climate compliance more accessible, credible, and practical.
A Simplified Path Towards California Climate Compliance
SB 253 and SB 261 raise expectations for transparency. Companies will now need to:
- Measure and disclose their carbon emissions.
- Publicly report on climate-related financial risks.
Carbonhound streamlines data collection and emissions calculations by connecting to primary data sources, from utility bills to logistics systems, and automating Scope 1, 2, and 3 carbon accounting. We eliminate the need for manual spreadsheets, helping businesses quickly understand their carbon footprint and start managing it more effectively.
Blue Sky Climate offers a two-pronged service model:
- For companies needing support with climate risk disclosures, Blue Sky Climate provides advisory services aligned with SB 261, CDP, ISSB S2, and other global standards.
- For companies where no advisory work has been done, Blue Sky Climate independently verifies GHG emissions data using internationally recognized assurance standards like ISO 14064-3 and ISAE 3410. This includes a thorough review of emissions calculations, methodologies, and supporting evidence, resulting in an assurance certificate that strengthens stakeholder trust and regulatory readiness.
How We Complement Each Other
By using the independent services of Carbonhound and Blue Sky Climate in tandem, companies can:
- Navigate SB 253 and SB 261 efficiently by combining automation with expert verification.
- Improve emissions data accuracy and credibility.
- Enhance stakeholder confidence through third-party assurance.
- Build internal capacity via joint webinars, expert Q&As, and short-form eLearning.

Climate reporting requirements are expanding rapidly, but the process shouldn’t be a barrier to action. With Carbonhound’s automation and Blue Sky Climate’s independent assurance services, businesses can move forward with confidence, without excess complexity or cost.
