Foster a collaborative network of climate, DLT, and other emerging technology organizations (i.e. universities, NGOs, government, startups, corporations, multilateral development banks, etc.) that can create a center of gravity around the role of DLT and open source software to address challenges in the global climate action, policy and digital accounting space. A focus point of the SIG would be to turn this network into action under a common open source project that defines shared protocols, standards, and platform tools for a globally integrated climate accounting system to be operationalized. This open climate project can act as a shared initiative where participants can contribute value to and share explorations in the use of DLT alongside other emerging technologies such as IoT (Internet of Things), big data, and machine learning to address the challenge of keeping a transparent climate accounting system towards the climate targets set in the 2015 Paris Agreement.

• Compilation of completed, ongoing, and proposed future activities related to blockchain for climate action & accounting
• Directory of organizations and initiatives involved with blockchain and the climate space (map of organization location, contact person, description, website, etc.)
• Consolidate the architecture of an integrated system, involving multiple blockchain mechanisms connected through shared protocols, allowing contractual automation in the link between finance and climate value flow based on the agreed physical parameter of the Earth system
• Identify Hyperledger tools and frameworks to develop and maintain a single record-keeping ledger with global consensus (i.e. a ‘ledger of ledger’ where all parties agree)
• Propose and define shared protocols and standards to allow interoperability across the climate accounting system and integrated platforms
• Compilation of best practices, lessons learned, and recommendations to stakeholders (policymakers, technology developers, etc.)
• Supporting events (e.g. at blockchain and climate conferences such as COP) and related activities for collaboration among members and stakeholders.
• Propose, discuss and define a longer-term strategic vision of an open innovation consortium that can help steward, fund, and maintain an open source climate action and accounting project and system

Global climate accounting occurs in a diverse set of digital tools and registry platforms that are individually centralized and collectively dispersed and unlinked. This is often due to the great diversity and proliferation of climate actions and climate accounting as well as the lack of trust between actors, resisting to share data that exposes them to scrutiny. Hence, a common framework and toolsets to seamlessly integrate climate action & accounting is a crucial component for a successful Paris Agreement and SDG13 (Climate Action), as well as emerging initiatives such as the FSB TCFD (Task Force for on Climate-Related Disclosurerelated Financial Disclosures). Leveraging blockchain by the participating network (countries, companies, and individuals) will be the key technology in the pursuit of helping maintain a decentralized “ledger of ledgers” and common platform.

Engaging and connecting the wider Hyperledger community with the growing communities that have developed in the climate-blockchain intersections (e.g. Climate Chain Coalition, Climate Ledger Initiative, etc.) will help identify potential challenges and advance opportunities to support Hyperledger-related solutions towards an integrated climate action and accounting mechanism.

The scope of the SIG is defined by the terms "climate action" and "climate accounting", defined in the introduction as encompassing and complementary concepts and illustrated below. The SIG can further be organized in working groups around 5 climate domains: Earth system state, World system registries, Climate action certification, Networked climate markets, Climate finance.

Whilst this special interest group will consider the role of supply chains in climate accounting, these will be considered generally but not in-depth so as to not overlap with more supply chain specific groups at Hyperledger. Furthermore, this interest group involves all matters of climate change but does not encompasses encompass other aspects of sustainability (e.g. biodiversity, non-greenhouse gas pollutants, socioeconomic socio-economic inequalities, etc.).

Particularly, the CA2-SIG will coordinate directly with stakeholders interested in using digital solutions for climate action and accounting, including other climate and blockchain initiatives such as (but not limited to) , the International Association for Trusted Blockchain Applications (INATBA), and the Climate Ledger Initiative.

The UN Climate Change Secretariat recognizes the potential of digital solutions for Climate Action, and in 2017 helped launch the Climate Chain Coalition (CCC) as an open global multi-stakeholder initiative to support collaboration among members and stakeholders. The initiative aims to advance the use of blockchain (distributed ledger technology) and related digital solutions (e.g. IoT, big data) to help mobilize climate finance and support climate policy, including enhancing MRV (measurement, reporting, and verification) to track and to scale up climate actions for mitigation and adaptation (e.g. technologies, projects, programs, markets), and to build trust among stakeholders. Demonstrating the global interest in blockchain for Climate Action, the CCC continues to grow at a rate of 2 new organizations per week and now has approximately 180 members across 45 countries.
