# Green Earth > Green Earth is a publicly traded nature-restoration company that helps businesses measure, reduce, compensate for, and report on their environmental footprint through high-quality, independently verified nature-based carbon projects. Green Earth develops its own large-scale nature-based projects — reforestation, afforestation, agroforestry, and energy-efficient cookstoves — all offering multiple environmental and socio-economic benefits alongside carbon sequestration. Its carbon credits are verified by leading standards such as Verra's Verified Carbon Standard (VCS) and the Gold Standard, with each credit representing one tonne of CO2 reduced or removed. Its business carbon footprint calculator — CO2 Expert — follows international guidelines including the GHG Protocol, ISO 14064, and ISO 14068-1, and offers expert carbon footprint validation. The customer journey runs in four steps: measure your footprint, implement reduction strategies, compensate for what remains with high-integrity carbon credits, and report transparently. The free online CO2 Expert tool supports both footprint measurement and direct purchasing of carbon credits. ## Carbon footprint - [Carbon footprint measurement](https://www.green.earth/carbon-footprint-calculator): How a business can calculate its full carbon footprint, including Scope 1, 2, and 3 emissions, with the Co2 Expert tool — from measurement through to reduction and reporting. ## Carbon credits - [Carbon credits](https://www.green.earth/buy-carbon-credits): Green Earth's global portfolio of certified carbon projects on its carbon marketplace with carbon credits verified by Verra and the Gold Standard, that help companies reach net zero and offset emissions. ## Projects - [Nature-based carbon projects](https://www.green.earth/projects): Green Earth's portfolio of nature restoration, livelihood improvement, and sustainable projects, like reforestation, agroforestry, and energy-efficient cookstove initiatives. ## Optional - [About Green Earth](https://www.green.earth/about-us): Company background — Green Earth's mission, board of directors, and its carbon, biodiversity, and plastic solutions. - [Green Earth stock market listing](https://www.green.earth/about-us/our-stock-market-listing): Green Earth Group N.V. is publicly traded on Euronext Amsterdam under ticker EARTH (ISIN NL0009169515) — how to buy shares through major brokers and where to track the live price.
