Question 1

How long does the carbon footprint quiz take?

Accepted Answer

Nine tap-only questions, about a minute. You get your estimated annual footprint in tonnes of CO2e, compared against the world average and the 2030 target.

Question 2

How much does it cost to offset my footprint with mangroves?

Accepted Answer

Each mangrove costs $1 a month. The quiz sizes a monthly plan to your own footprint, so most plans are a few dollars a month. You can cancel anytime from your Stripe receipt email.

Question 3

How do I know the trees are really planted?

Accepted Answer

Every planting is filmed by the planter, GPS tagged and AI tree-counted, and verified plantings can be watched on the live globe at world.treegens.app. The quiz results page plays real before and after footage from a verified planting.

Question 4

What happens if a tree dies?

Accepted Answer

Every tree is guaranteed through the Treegens replanting program: any tree that fails is replanted, and extra trees are planted as a survival buffer, so your plan stays covered.

Question 5

Does using AI tools increase my carbon footprint?

Accepted Answer

Far less than headlines suggest. At roughly 1 gram of CO2e per query, even daily AI use adds under 1 percent to a typical personal footprint. The quiz counts it honestly alongside travel, diet, home energy and shopping.
