Frequently Asked Questions

Coffset FAQ

What is a carbon footprint and how is it calculated?

A carbon footprint is the total amount of greenhouse gases, primarily carbon dioxide (CO2), that are generated by an individual's, family's, or organization's actions. Coffset calculates this by using established emission factors. You provide data through a simple questionnaire about key areas like your home energy consumption, transportation habits (car, flights, public transit), and general lifestyle. The calculator applies scientific conversion rates to this data to estimate your total annual emissions in tonnes of CO2 equivalent.

How can I be sure my offset contribution is making a real difference?

Coffset ensures impact by exclusively supporting carbon reduction projects that are verified under rigorous international standards, such as the Verified Carbon Standard (VCS) or the Gold Standard. These certifications require projects to prove they are "additional" (would not have happened without carbon credit revenue), permanent, and accurately measured. Each contribution you make is tied to a specific, certified project, and you receive a verifiable certificate as proof, guaranteeing your funds drive real, quantifiable environmental benefits.

What kinds of projects does Coffset support?

Coffset funds a diverse portfolio of verified projects that actively remove or prevent greenhouse gases from entering the atmosphere. Examples include reforestation and forest conservation initiatives that absorb CO2, landfill gas capture projects that destroy potent methane emissions, and renewable energy installations like wind or solar farms that displace fossil fuel power. Many projects also deliver co-benefits like protecting biodiversity, improving air quality, and supporting local communities.

Is offsetting with Coffset a substitute for reducing my own emissions?

No, offsetting is a complementary action, not a substitute. The most effective climate strategy follows a clear hierarchy: first reduce your emissions wherever possible (e.g., using less energy, choosing sustainable transport), then offset the emissions that are currently unavoidable. Coffset is designed to help with the latter. The platform also provides insights from your footprint calculation that can help you identify areas for personal reduction, making it a tool for both compensation and education.

Zovo FAQ
