At the 2022 Web Summit, Dr. Leemon Baird joined a panel titled "Is crypto that doesn’t hurt the environment possible?" This thought-provoking question was the focal point of this panel, which led me to ponder the ecological consequences of various distributed ledger technologies (DLTs) and their applications.

When discussing energy consumption and carbon emissions, people tend to immediately think of the carbon footprints left by vehicles and factories. However, it's crucial to also take into account the energy usage of proof-of-work (PoW) DLTs and their use cases such as cryptocurrencies like Bitcoin. These digital currencies require extensive computing resources and generate a significant amount of carbon emissions. In fact, the energy consumption of Bitcoin alone is equivalent to that of the entire Netherlands.

Hedera's carbon-negative network presents a sustainable option in the world of DLTs. Utilizing a proof-of-stake consensus mechanism greatly reduces carbon emissions. In addition, the network actively addresses climate change through various initiatives including developing sustainability tools, supporting green projects, and making donations to organizations working on climate trade.

Hedera's carbon-negative network not only offers a sustainable option in the world of DLTs, but also boasts superior performance compared to other blockchain alternatives.

An updated study by the UCL Centre for Blockchain Technologies found that Hedera has the fastest transaction speed, the highest number of transactions per second, and the lowest energy consumption when compared to leading blockchain networks such as Algorand, Cardano, Ethereum, and Solana. This is not just a claim, but factual proof that Hedera's network is an ideal choice for businesses looking to adopt a reliable, efficient, and environmentally friendly blockchain solution.

In addition to its sustainable DLT, Hedera and the HBAR Foundation have also developed an open-source solution called Guardian. This framework includes a Policy Engine that allows for the creation of digital monitoring, reporting, and verification (MRV) systems for environmental, social, and governance (ESG) assets such as carbon emissions, carbon offsets, and renewable energy certificates (RECs). The Guardian provides auditable, traceable, and reproducible records that document the emission process and life cycle of carbon credits, enabling a policy-driven approach to defining projects such as carbon removal.

Hedera takes proactive measures to promote sustainability, including regularly purchasing carbon offsets and actively engaging in global forums like COP27 and Davos 2023 to raise awareness about the benefits of its technology and build bridges with world leaders and organizations to promote sustainable practices. Hedera sets an example for other DLT players to prioritize sustainability in their operations and goals.

Hedera Sustainability Use Cases

Hedera's commitment to sustainability goes beyond just theory and promises. The network has been implemented in various industries to drive real results in sustainability. Here are a few examples of companies that are using the Hedera technology to improve their environmental and social impact:

Avery Dennison (
