Reality check: Six questions about carbon offsets

As more and more airlines, travel-related companies and websites offer carbon offsets to neutralize the impact of our day-to-day activities on the climate, people are faced with the seemingly daunting task of figuring out what offset projects are doing the most to reduce greenhouse gas (GHG) emissions, the gases that are causing climate change. There are a wide variety of projects to choose from, including composting organic waste, changing forestry and farming practices and preventing emissions of industrial gases.

The key is to make sure that the emission reductions are real. So how do you do that? Here are six questions you should ask before you buy.
1. Where is it registered?
2. What makes it additional?
3. Where is it located?
4. What kind of project is it?
5. What vintage is the offset?
6. Are the greenhouse gas reductions permanent?
