The "most affordable" solution to climate change

The building, transport and power sectors in the G8 countries, together with five leading developing countries (Brazil, China, India, Mexico and South Africa) have the biggest potential for saving energy.

In fact, they could increase energy efficiency by a total of 20% by 2020, according to a report commissioned by WWF.

"There is no one silver bullet to stop dangerous climate change, but energy efficiency is the largest and most affordable solution available to avert the current crisis," says Hans Verolme, Director of WWF's Global Climate Change Programme.

He claims that endorsing these targets is technically and economically feasible for all countries. The report estimates the efficiency potential for each sector by the year 2030 as:

• the transport sector: 25-50%
• the building sector: 30-45%
• the power sector: 4-45%, depending on the country.

Recommended measures include standard setting, labelling for energy efficiency, fiscal instruments such as subsidies or tax credits, and a CO2 or energy tax.

Increased energy conservation would result in cost savings, an increase in energy security, and provide new business opportunities and increased employment.
