Planting Trees Won't Save the World

One trillion trees.

At the World Economic Forum last month, President Trump drew applause when he announced the United States would join the forum’s initiative to plant one trillion trees to fight climate change. More applause for the decision followed at his State of the Union speech.

The trillion-tree idea won wide attention last summer after a study published in the journal Science concluded that planting so many trees was “the most effective climate change solution to date.”

If only it were true. But it isn’t. Planting trees would slow down the planet’s warming, but the only thing that will save us and future generations from paying a huge price in dollars, lives and damage to nature is rapid and substantial reductions in carbon emissions from fossil fuels, to net zero by 2050.

Even a 16-year-old can tell you that.

Focusing on trees as the big solution to climate change is a dangerous diversion. Worse still, it takes attention away from those responsible for the carbon emissions that are pushing us toward disaster. For example, in the Netherlands, you can pay Shell an additional 1 euro cent for each liter of regular gasoline you put in your tank, to plant trees to offset the carbon emissions from your driving. That’s clearly no more than disaster fractionally delayed. The only way to stop this planet from overheating is through political, economic, technological and social solutions that end the use of fossil fuels.
