Ron- Your assertion is ambiguous: do you mean 6% emission reduction per year, or 6% GHG level reduction per year?
6% annual emission reduction could be easily accomplished with WW III or a major recession, even with today's economic regime. Achieving a 6% annual reduction would not leave us with a known safe GHG level though. CO2 is 40% higher than the highest humans have ever survived long-term. That was 300 ppm. Any level above that (especially 40% above it) is playing Russian roulette with our children--which is, or should be, considered immoral in our society. Reducing GHG (CO2 equivalent) levels faster than 6% per year could be done with accelerated atmospheric methane oxidation, at low cost (see my book).
