Climate Impact Portfolio

When you offset carbon with Sustainable Travel International, we maximize your impact by distributing each dollar across our mixed portfolio of climate projects. Though the particular projects in our portfolio vary from one quarter to the next, your offset purchase will always support a mix of high quality forestry, energy, blue/teal carbon, and innovative tech projects.

Our Project Types

Our Climate Impact Portfolio is comprised of four types of carbon offset projects, all of which play an essential role in the fight against climate change by avoiding or removing carbon emissions.

Monkeys in the trees in the Amazon rainforest


Forestry projects protect, restore, and improve sustainable management of forest ecosystems. Safeguarding these critical habitats plays a vital role in carbon sequestration, while conserving biodiversity and the life-sustaining benefits that forests provide.

Wind farms generating clean, renewable energy


Energy projects decrease carbon pollution from energy use by reducing reliance on fossil fuels. Clean energy projects fund renewable energy infrastructure, while efficiency projects support the application of new technologies or practices that lessen energy use.

Blue & Teal Carbon

Blue and teal carbon projects protect coastal and freshwater ecosystems that store substantial amounts of carbon. Along with sequestering carbon, these ecosystems protect communities from harmful climate impacts, provide habitats for marine life, and support the blue economy.

Innovative Tech

Innovative tech projects offer novel solutions to the climate crisis. For instance, solutions like soil carbon sequestration and direct air capture use inventive methods to remove CO2 from the air. These emerging climate technologies require additional financial support to bring them to scale.
