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:
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.
