Carbon offsets overview
There are many reasons to buy carbon offsets. You might want to zero out your emissions from your recent vacation, or maybe you drive to work every day and want to offset emissions from your commute instead of investing in an electric vehicle.
However, not all offsets are the same, and companies offering carbon offsets can differ in their criteria and options. What kind of program will your funds go towards? Will it fund renewable energy projects, planting trees, or use some other method? Before purchasing an offset, it’s important to research how it will be implemented to counteract greenhouse gas emissions.
The best carbon offsets are verified by a third party to ensure that the companies offering offsets are implementing the environmental projects you are paying for and have legitimate offset programs. If an offset is verified, information about the verifiers is generally easy to find on the offset company’s website. Common verifiers include the American Carbon Registry, Climate Action Reserve, and Verified Carbon Standard.
