There are two types of offsets; tree-planting programs and energy efficiency programs.
Trees remove carbon from the atmosphere and can benefit conservation and wildlife. Some things to consider:
- Ensure the trees are native trees to assist with conservation efforts
- Will the trees be logged after a certain time for commercial purposes?
- How are the trees protected from bushfires or illegal logging?
- How are the emission reductions calculated?
- Is the program independently accredited?
Energy efficiency programs can reduce future greenhouse emissions but do not actually absorb the carbon you have produced. Some things to consider:
- Is the program well set up so the energy reductions are real and ongoing? (eg giving out free compact fluorescent globes doesn't mean they'll be used)
- Should I be investing in this program or is it something that should be happening anyway? (eg are you paying for a large company to reduce their emissions when they really should be doing this themselves)
- Is the program independently accredited?
