In a historic move for global climate action, the International Organization for Standardization (ISO) and the Greenhouse Gas Protocol (GHG Protocol) have announced a strategic partnership to harmonize their standards. This collaboration will create a single, globally recognized framework for greenhouse gas (GHG) emissions accounting and reporting, marking a new era of clarity and consistency in the fight against climate change.
For years, the climate action landscape has been fragmented, with companies navigating separate standards from both organizations. This partnership directly addresses that challenge by combining the technical rigor of the ISO 1406X standards with the practical, widely-adopted GHG Protocol Corporate Standards. The result will be one coherent, co-branded suite of standards that simplifies reporting, increases data credibility, and reduces the burden on all users.
A key focus of the partnership is the development of a joint product carbon footprint (PCF) standard, reflecting the growing industry demand for more granular, supply-chain-specific data to guide effective decarbonization.
This move toward transparent, detailed data aligns perfectly with our core mission at Arbor. We have always championed precise, bottom-up carbon calculations to help companies make measurable progress.
"This is exactly what our product was built for,"
said Ben Grande, Arbor's CTO.
"Unlike most carbon accounting software, we started with product-level measurements, knowing that one day these would be used to accurately measure Scope 3 emissions. This fundamental update to the GHG protocol will drastically reduce reporting risk and improve companies' ability to decarbonize strategically."
The harmonized portfolio represents a major step towards a common global language for emissions accounting, which will accelerate coordinated and effective climate action worldwide.
It is a strategic collaboration to merge existing greenhouse gas (GHG) standards and co-develop new ones. The goal is to create a single, unified global framework for emissions accounting and reporting to support businesses in their decarbonization efforts.
The partnership aims to reduce complexity and fragmentation in the GHG reporting landscape. By creating a common global language for emissions accounting, the organizations will improve the consistency and comparability of climate data, making it easier for businesses to take effective action.
The key benefits include simplifying the GHG accounting process, improving the credibility of reported data, and reducing reporting burdens. This alignment also supports regulatory efforts and enhances investor confidence through a stronger, more coherent verification framework.
Existing standards from both organizations will remain in effect until the new, co-branded standards are published. The transition will be managed through a transparent process designed to ensure compatibility and minimize disruption for all users.

The California Air Resources Board (CARB) has published a preliminary, non-final list of companies it believes may be subject to new climate disclosure laws SB 253 and SB 261. This initial step requires all companies doing business in California to verify their status based on revenue thresholds, regardless of their inclusion on the list.
The California Air Resources Board (CARB) today released a preliminary list of companies it believes may be subject to the state's landmark climate disclosure regulations, for SB 253 and SB 261.
With an estimated 4,160 companies affected, the ripple effect on their global supply chains is massive.
This publication is a significant step in the regulatory process, but CARB has emphasized that it is not a final determination.
To develop this initial list, CARB matched business data from the California Secretary of State (SoS) with a proprietary dataset. Staff noted the SoS data was only active through March 2022 and may be missing companies.
CARB has released FAQs and held public workshops to clarify exemptions, reporting frameworks, and timelines.

CARB is the lead agency for California’s fight against climate change, and oversees all air pollution control efforts in the state to attain and maintain health-based air quality standards.

Just don't do it.
The UK’s advertising watchdog (ASA) has officially banned ads from Nike, Lacoste, and Superdry for misleading green claims.
Here is what happened:
1️⃣ Nike ran a paid ad featuring a tennis polo with the tagline "Sustainable Materials." Nike argued that this referred to their broader collection of products made with recycled materials.
2️⃣ The regulator rejected this defense.
3️⃣ They ruled that the ad implied the specific product had no detrimental effect on the environment, a claim Nike failed to substantiate.
4️⃣ Crucially, the ASA stated that evidence must account for the product's entire life cycle, not just the materials used.
5️⃣ Lacoste and Superdry faced similar bans for using vague terms like "sustainable clothing" and "sustainable style" without providing rigorous proof of environmental benefit.
The standard has shifted.
Simply using recycled polyester is no longer a free pass to claim "sustainability."
You now need to prove that your product is better across its full life cycle.
Arbor provides the audit-grade data required to substantiate these claims.
Our platform calculates the full carbon footprint of your products using a bottom-up methodology that covers the entire life cycle.
Don't guess. Measure.

Arbor wins Best Carbon Accounting Software 2026 and Q4 2025 Product Award, saving clients 1.8M hours in manual reporting time.
Arbor, the industry-leading platform for automated product carbon footprinting (PCF), today announced it has been named "Best Carbon Accounting Software 2026" by the Canadian Business Awards from Corporate Vision.
This recognition coincides with a major operational milestone: Arbor’s platform has now measured over 1 billion kg of CO2e across 122,000+ products, saving enterprise clients an estimated 1.8 million hours of manual reporting time compared to traditional Life Cycle Assessments (LCA).
As regulatory frameworks like the EU CSRD (Corporate Sustainability Reporting Directive) and CBAM intensify, global enterprises are abandoning spreadsheet-based models in favor of Arbor’s audit-grade AI automation.
With the recent ISO-GHG Protocol partnership and SBTi V2 updates, companies are now required to adapt to PCF and LCA-level accuracy for their Scope 3 reporting.
Additionally, index providers like MSCI increasingly rate Scope 3 as a major contributor to company ratings in Climate Indexes, directly linking accurate data to business value.
Arbor’s innovative approach and rapid growth have garnered significant industry recognition, including:
• "Best Carbon Accounting Software 2026" by Canadian Business Awards (Corporate Vision)
• "Q4 2025 Product Award Winner" by Products That Count
• "Top 100 Next Generation Company" by World Future Awards
• "EQ Bank | Equitable Bank Sustainable Finance Award" for innovation in measuring financed emissions
