Sky is teaming up with WWF for a project to help save one billion Amazon rainforest trees from destruction.
Rainforests are one of the richest stores of carbon on earth and every minute an area larger than three football pitches of Amazon forest is lost.Such destruction is releasing more greenhouse gases into the atmosphere than the entire global transport sector.
So halting deforestation would seem like one of the most obvious ways to tackle climate change.
But protecting the world's forests has so far proved difficult.
In many parts of the world, the wood from the trees is worth far more dead than alive and international efforts to change this balance have had limited success.
Now, as momentum builds in the weeks before December's climate negotiations in Copenhagen, there are some signs of progress.
Brazil's President Lula Da Silva has suggested that his country may aim to cut deforestation by 80% over the next 10 years.
The UK has announced it will give £100m to a global fund to tackle poverty and deforestation.
Sky wants to do its bit too. Every £10 donated to the Rainforest Rescue site will help to protect around 500 trees - Sky will match every donation made, up to the value of £2m.
The aim is for the Brazilian state of Acre to act as a role model for conservation in Brazil and the project will help local communities to look after their forests.
Each year, around 22 million tons of CO2 are created by deforestation in this state alone.
Rainforests are the most diverse ecosystems on earth but they are rapidly diminishing.
Colin Butfield, head of Campaigns at WWF told Sky News Online: "We've lost over half the forests on the planet, to give you an idea of the speeds they're going, we lose about the size of 36 football pitches every minute - so that's pretty fast."
Tropical forests are home to more than half the world's known species of plants and animals and destroying them is contributing to climate change on a massive scale.
They also play a critical role in regulating our climate and in sustaining the local water cycle.
