With Carbon Down, you can take effective individual action to address climate change, and will have the tools to enact wider change.

We help you understand, reduce, and offset your carbon emissions. With a short carbon footprint calculator, we help you understand your CO2 emissions. By taking personal action, these can be reduced. You can go green with our offerings of gold standard carbon offsets for your unavoidable carbon emissions. By supporting our vetted projects, you can protect forests, plant trees, fund renewable energy, etc., while removing your carbon emissions from the atmosphere.

Carbon Down was founded to remind people that we have the ability to enact tremendous change in a crisis we all care about: climate change. We can choose not to resign to the status quo, but rather to fight against it, because we believe in a better future for ourselves, for our society, for our children, and for our planet. While we all contribute to the climate crisis, we also play an integral role to the climate solution.

Getting Started:

- Download Carbon Down to put the power to end climate change in your pocket.
- Use an easy, carbon footprint calculator to calculate your emissions.
- Choose a carbon offset project that most closely aligns with environmental issues you want to support to offset your emissions.
- Scale your climate impact by inviting friends & family to grow our reach.

Frequently Asked Questions:

1. What is a Carbon Offset / Carbon Credit?
Carbon credits, also known as Verified Emission Reductions (VERs), are certified carbon offsets validating that one metric tonne (1000kg or 2204.6 pounds) of CO2 has been offset, meaning one tonne of carbon dioxide has been taken out of the atmosphere and stored long term, or that one metric tonne of carbon dioxide has been prevented from being emitted into the atmosphere.

2. Where does my money go when I purchase Carbon Offsets?
All funds spent to offset your emissions goes directly to the projects that offset your emissions. We use a secure 3rd party, Stripe, to handle your financial information, which charges a little over $0.30 per transaction. The rest of your money goes to our Project Developers, who offset your carbon.
