Global warming and climate change are rapidly being recognised – by governments, industry and consumers worldwide – to be the most serious challenge facing the human race now and into the future. The Emerald Planet Trust has been active in this arena for many years with its current activity focusing through two companies:

Climate Friendly™ is an Australian-based company that helps commercial and residential customers neutralise carbon emissions from their home, business, car, travel or any other activity that uses energy, at the same time as contributing to growing the clean energy industry. The carbon credits purchased on customers' behalf come from accredited and new renewable energy projects, contributing to the growth of the renewable energy industry, the long term solution for global warming.

In 2007, Climate Friendly formed a partnership with WWF-Australia to strengthen our mission to encourage individuals and businesses to become climate neutral.

STWA owns the worldwide manufacturing and marketing rights to revolutionary ZEFS and CAT-MATE devices that, after fitting to internal combustion motors, reduce carbon monoxide (CO); hydrocarbons (THC), nitrous oxide (NOX) and other toxic exhaust emissions.
STWA patented/patent pending devices are specifically engineered to minimize environmental pollution, to enhance fuel system performance and to increase engine efficiency. Variations of these devices can be attached to the internal combustion engines or exhaust systems in most automobiles, motorcycles, off-road vehicles, generators and other stationary implements.
