How the pope is saving Earth
Pope Benedict XVI, like many world leaders, has spoken passionately about the urgent need to protect the planet from climate catastrophe. But unlike his fellow heads of state, the pontiff has actually created a carbon-neutral economy -- and done it cheaply and quickly.
The Vatican announced last year that it would restore 37 acres of forest in Hungary that had been cut down in the Middle Ages. Those growing trees will absorb enough carbon dioxide to offset all the pollution from the fossil fuels used to power Vatican City.
The reason this "Vatican model" succeeded while other countries struggle to achieve even modest emissions reductions is because of the unique qualities of forest conservation and restoration. Compared with other methods of reducing climate-changing pollution, such as switching to wind, solar or geothermal power, it's fast and relatively cheap. That's true on a small, Vatican City scale as well as a massive American scale.
It's particularly true when it comes to the carbon-rich tropical forests that act as the Earth's lungs, breathing in carbon dioxide and breathing out oxygen. These forests are being logged and burned at a terrifying pace by big agricultural, biofuels and mining companies. Between August 2007 and April 2008, for instance, big ag and its cohorts destroyed a whopping 2,300 square miles of the Amazon, releasing 300 million tons of CO2 into the air in the process. Compounding that disaster, the treeless land generally loses its capacity to absorb the greenhouse gases produced by the world's fossil fuel consumption.
The good news is that stopping that destruction -- by purchasing the land outright or paying landowners and others to conserve it -- is a bargain. Because of the low cost of tropical land, protecting these forests can cost as little as $1 per ton of CO2 saved and almost never more than $10 a ton. (For comparison, cleanups based primarily on energy now trade for more than $40 a ton on European markets.)
As a result, the World Bank and others estimate that global deforestation could be completely halted for the relatively tiny sum of $11 billion to $15 billion a year. That one move alone would eliminate 20% of total global warming pollution.
Despite the urgency of the problem -- and the ease of the solution -- forest conservation has, until recently, been the forgotten stepchild of climate legislation. For many years, policymakers (particularly in Europe) were nervous that polluters would abuse the system by using low-cost overseas forest conservation projects as an excuse to avoid cleaning up industrial pollution at home.
