What was the problem?
What was the problem?
Sustainable tourism is crucial for preserving our planet, yet travellers often find it difficult to identify and choose eco-friendly options. This app not only empowers users to make sustainable travel choices but also embodies its own mission by minimising its environmental footprint through energy-efficient UI/UX design.

What is carbon offsetting
Carbon offsetting works by compensating for greenhouse gas emissions produced by activities like travel, manufacturing, or energy use by funding projects that reduce or remove equivalent emissions elsewhere.
Verified Carbon Standard (VCS)
Prices for VCS carbon credits vary widely depending on the project type, location, and demand, typically ranging from $5 to $15 per credit.
Gold Standard
The price per Gold Standard credit is generally higher due to its focus on co-benefits, averaging between $10 and $20 per credit.
Climate Action Reserve
Prices for credits under this standard typically range from $2 to $8 per credit, influenced by project type and location.
