Frequently Asked Questions

Coffset FAQ

How does Coffset ensure the quality of its carbon offset projects?

Coffset meticulously selects projects that are certified under internationally recognized standards like Verra (VCS) or the Gold Standard. These certifications require rigorous third-party validation to ensure the carbon reductions are real, measurable, permanent, and additional—meaning they would not have occurred without the offset funding. Each project in our portfolio is transparently documented for you to review.

What is the difference between calculating my footprint and offsetting it?

Calculating your footprint is the diagnostic stage—it's the process of measuring the CO2 emissions you are responsible for from activities like driving, flying, and home energy use. Offsetting is the action stage—it involves financially supporting verified environmental projects that reduce or remove an equivalent amount of CO2 from the atmosphere, effectively neutralizing your calculated impact.

Can I use Coffset to offset emissions from a specific activity, like a flight?

Absolutely. Coffset is designed for both comprehensive and targeted action. You can use the calculator to estimate emissions from a specific flight, road trip, or other event. The platform then allows you to purchase offsets specifically for that calculated amount, providing a focused way to mitigate the impact of individual high-emission activities.

What kind of projects does my contribution support?

Your contributions support a diverse portfolio of verified carbon reduction projects. This includes nature-based solutions like reforestation (e.g., TIST Program in Uganda) and mangrove restoration (e.g., Delta Blue Carbon), as well as technology-based initiatives like capturing methane from landfills to generate clean electricity (e.g., Fuzhou Hongmiaoling) and investing in frontier carbon removal technologies.
