This week’s brief highlights continued expansion across Net Zero Compare, with 2 new or updated policies, 21 software products, and 106 industry events added. Featured policy developments such as the Marrakech Partnership for Global Climate Action and California Assembly Bill AB 2446 show how climate action is advancing through both global collaboration frameworks and more specific regulatory approaches to embodied carbon in construction.

The latest software additions also reflect growing demand for better emissions data, lifecycle insight, and sustainability management across sectors. greenStruct focuses on carbon accounting for construction projects and building materials, while GreenScope supports broader carbon accounting and ESG monitoring workflows. Together, they point to a wider market need for tools that can improve data quality, support audit-ready reporting, and help organizations move from climate ambition to measurable implementation.

In this issue, we cover policy signals shaping global climate collaboration and low-carbon construction, introduce tools for carbon accounting and ESG monitoring, highlight upcoming events on ESG strategy, green ports, and packaging regulation, share community perspectives on carbon accounting bottlenecks, and spotlight Orbify’s role in using geospatial intelligence to support environmental monitoring and climate decision-making.

This week, we added 2 new or updated policies to our website, including:

What happened
The Marrakech Partnership for Global Climate Action is a UNFCCC-linked initiative that supports cooperation between governments and non-state actors to accelerate climate action. It helps mobilize businesses, cities, regions, investors, civil society, and other stakeholders around practical implementation of the Paris Agreement, with a focus on sectoral transformation, resilience, mitigation, and stronger collaboration across the climate action ecosystem.

Who is affected
Businesses, cities, regional governments, investors, civil society organizations, NGOs, international institutions, climate coalitions, sector initiatives, and policymakers working on climate mitigation, adaptation, resilience, finance, and net-zero transition planning.

Why it matters
The partnership is important because climate action increasingly depends on coordination beyond national governments. It helps connect policy ambition with implementation by encouraging sector-level action, voluntary commitments, collaboration, and progress tracking across non-state actors. For organizations, it provides a broader framework for aligning climate strategies with global climate goals, strengthening accountability, and contributing to real-economy decarbonization.

What to monitor next
Monitor updates from UN Climate Change, the High-Level Champions, sectoral climate action pathways, COP-related announcements, and new commitments from businesses, cities, regions, and investors. Also watch how the partnership supports implementation of national climate plans, climate finance, adaptation priorities, and credible net-zero transition efforts.

What happened
California Assembly Bill AB 2446 requires the California Air Resources Board to develop a framework for measuring and reducing the average carbon intensity of materials used in new building construction. The law focuses on embodied carbon in construction materials, particularly emissions linked to material production, and supports the use of lifecycle assessment, environmental product declarations, and carbon-intensity data to guide lower-carbon building decisions.

Who is affected
Building developers, construction companies, architects, engineers, material manufacturers, public agencies, local authorities, sustainability teams, procurement teams, and organizations involved in designing, financing, regulating, or supplying materials for new buildings in California.

Why it matters
AB 2446 is important because embodied carbon is a major part of the climate impact of buildings, especially as operational energy efficiency improves. By requiring a framework to measure and reduce the carbon intensity of construction materials, the law pushes the building sector toward better material transparency, lower-carbon procurement, and more consistent use of lifecycle data in construction planning. CARB describes the policy objective as supporting reductions in embodied carbon from building materials, with a target of a 40% net reduction in greenhouse gas emissions by the end of 2035.

What to monitor next
Monitor CARB’s implementation framework, future embodied carbon thresholds, links with Buy Clean California requirements, updates to building codes, and the role of EPDs and LCAs in project approvals and procurement. Also watch how AB 2446 interacts with AB 43, which allows California to consider an embodied-carbon trading system as part of its implementation.

This week, we added 21 new software products to our website, including:

Category: Carbon Accounting
Target Market: Architects, engineers, construction companies, developers, sustainability teams, material suppliers, and organizations seeking to measure, compare, and reduce the carbon impact of buildings and construction materials.
Recent Context: The construction sector is facing growing pressure to address embodied carbon, improve material transparency, and use lifecycle data in building design and procurement. As regulations and market expectations around low-carbon construction increase, tools that help teams assess emissions at the material and project level are becoming more important.

GreenStruct is a platform designed to support carbon accounting and sustainability analysis for construction projects. The software helps users assess the environmental impact of building materials, compare lower-carbon options, and integrate emissions considerations into design and procurement decisions.

Category: Carbon Accounting and ESG Monitoring
Target Market: Companies, sustainability teams, ESG managers, finance teams, compliance professionals, and organizations seeking to measure emissions, monitor sustainability performance, and prepare climate-related reporting.
Recent Context: Organizations are facing growing pressure to improve the quality of emissions data, align sustainability reporting with evolving disclosure expectations, and move from manual spreadsheets toward more structured carbon and ESG management systems. There is rising demand for platforms that help teams centralize data, track progress, and support more credible climate action.

GreenScope is a platform designed to help organizations manage carbon accounting and ESG monitoring workflows. The software supports emissions data collection, sustainability performance tracking, reporting preparation, and decision-making around reduction opportunities.

Reddit users in r/carbonaccounting are discussing whether the biggest bottleneck in carbon accounting is methodology or data management. The discussion points strongly toward the operational side of the process: collecting reliable activity data from different teams, maintaining audit trails, managing emission factor sources and versions, handling Scope 3 supplier data, and keeping inventories consistent across reporting years. Several participants note that emissions calculations become relatively straightforward once data sources and emission factors are consistent, while coordinating inputs across departments, regions, and suppliers remains much harder. The conversation also highlights the limits of relying on spreadsheets as carbon accounting matures. Spreadsheets may work for an initial footprint, but become harder to manage when companies need collaboration, traceability, historical comparisons, and verification readiness. The broader takeaway is that carbon accounting is increasingly a data governance challenge, requiring clear ownership, structured workflows, supplier engagement, version control, and audit-ready documentation, not only emissions calculation methodology.
