For many years, small farmers in developing countries have been blamed for deforestation because of the way that they make breakfast. While in developed countries nearly everyone cooks with fossil fuels, or with electricity generated by fossil fuels or hydroelectricity, in developing countries firewood still predominates, especially among the poorest people in rural areas. But is this really an important driver of deforestation—and thus a major contributor to global warming? A new study—the most in-depth and comprehensive look at the subject yet—says no.

Today we’re releasing an important report on what the world’s largest emitters of greenhouse gases could do to reduce the global warming pollution released by their land sectors—that is, their agriculture and forests. It’s called Halfway There? What the Land Sector Can Contribute to Closing the Emissions Gap.

You hear the phrase “we’re number one!” from Americans fairly often, usually in relation to sports or politics. Now new research from the Union of Concerned Scientists shows that there’s another domain where it applies. It’s not as an assertion of superiority, and probably never will lead to a chant at the Olympics, the World Cup or even the UN climate negotiations. Rather, it’s in terms of our potential to use our land sector – that is, agriculture and forests – to reduce our global warming pollution and avoid the worst consequences of climate change.

The new annual data on Amazon deforestation in Brazil has just come out, and it’s good news. For the latest year—August 2013 through July 2014—the annual total was 4,848 square kilometers. That’s 18 percent less than in the previous year, and the second-lowest figure ever. Read More

Thinking about trees often makes you think about your grandchildren. Both start small, can live for many decades, and will grow old in a world very different from ours today. And they’re connected. I expect that my granddaughter Esme, who just turned 1 ½, will probably live in a house made of wood, will write on paper, and perhaps will keep her house warm in the winter, as my wife and I do, with a wood stove. Have we thought about what trees that wood will come from? Read More

As I rode on the train back to Washington today, The Hershey Company announced its strengthened commitment to zero deforestation for all the palm oil it uses. This is another of the welcome corporate statements, over the last several months and indeed the last few days, that have recognized business’ responsibilities to reduce the damage that they cause to the climate.

I’m in New York City for the United Nations Climate Summit, and it’s an important week for tropical forests and the global climate. Read More

From time to time we take a look at things we published several years ago, to see whether they’re still up to date. We often need to decide whether to reprint them as is, revise them first, or simply decide to stop using them. This requires figuring out whether the information they contain is still valid, or has become somewhat obsolete in light of new science and recent political developments. Read More

I’m now in Bonn at the United Nations climate negotiations, where the big news is that in the last week the world’s two biggest emitters – China and the United States – have announced important actions to cut their carbon pollution, especially from the coal that they burn. These steps are welcome, but they are plans, not accomplishments, and they come late compared to other countries that have already acted to reduce their carbon dioxide emissions.
Ironically, most of these successes are in tropical developing countries, where countries’ reductions in rates of deforestation and in some cases their reforestation of cleared land have cut their net emissions of global warming pollution. Their actions have already accomplished more for the climate than the actions of many developed nations have.
