Smallholders and countryside enthusiasts will be flocking to Builth Wells for the annual Spring weekend where the spotlight is on smallholding. There will sections for all sorts of subjects, not least how to reduce your carbon footprint.

More than 25,000 people are expected to visit this year's Green Horizons 2008. It is a development of the pilot event held at the 2007 Festival and will comprise over 60 trade and demonstration stands providing practical solutions for the reduction of carbon emissions and their impact on the environment. The average personal carbon dioxide emission for an individual in the developed world is over nine metric tonnes and, as more people become aware of the effects on the environment of global warming, exhibitions such as this one take on a greater significance.

"Climate change is one of the most important issues facing the world today and each of us needs to examine ways in which we can make our own personal worlds less damaging to the environment," said Barrie Jones, Company Secretary of the Royal Welsh Agricultural Society. "Through Green Horizons 2008 we hope visitors will find out more about sustainable green products and services that can help them save energy, make better use of natural resources, and reduce their carbon footprint."

The exhibition space will be divided into themed zones with an emphasis on practical solutions that visitors can apply in their own lives. Exhibitors will include suppliers and installers of renewable energy equipment such as waterless toilet systems, greener building products, bio-fuels and woodland management, organic food and produce, and organic and Fair-trade clothing or household goods.

The Green Arena zone will feature a programme of talks, seminars, ask the expert' sessions and demonstrations by skilled sector workers. There will also be a programme of activities and entertainment especially for children.

The event will be staged in Exhibition Hall 3.
