Investing in changes of technology can bring ecological and social benefits in addition to CO₂ emissions reductions. A good example is the replacement of traditional open wood fires with high-efficiency cooking stoves.

This not only reduces CO₂ emissions but improves air quality, reduces de-forestation and cuts domestic fuel bills.

Innovative methods for renewable energy generation, such as hydro power, are now being integrated worldwide. One source, wind generated energy, is the fastest growing energy sector in the world. Yet the required technologies are still relatively expensive.

Revenue from carbon offsets can make such renewable energy projects viable that would not otherwise have happened.

Major energy savings can be achieved through the replacement of inefficient and conventional light bulbs with high efficiency alternatives.

Emission reductions projects, established around the world, overcome the initial barriers of cost and knowledge about energy efficiency. Using CFLs cost savings are achieved in the long run and bulbs will last up to ten times longer.
