  12. FACTS • Energy Efficiency • Comfort

  13. FACTS • Development and Food Consumption USA Meat Consumption/Capita/Year Brazil China UK India More Meat More Energy + More Water + More Land GNI / Capita / Year

  14. FACTS • Cost of Living • Arithmetic average of prices in four commodity sub-indices (food, non-food agro items, metals, and energy)

  15. FACTS • Carrying Capacity of Biosphere (Overloading!) • Effects on natural cycles (Sustainability!) The Environment Crisis !

  16. FACTS • Climate Change and GHG Emissions • Drivers of CC is anthropogenic substances and processes that alter the Earth’s energy budget • Main substances affecting the Earth’s energy budget is GHGs • GHG emissions continue accelerate despite reduction efforts - due to fossil fuel combustion industrial processes • The current trajectory of global annual and cumulative emissions of GHGs is inconsistent with widely discussed goals of limiting global warming at 1.5 to 2 C above the pre-industrial level • Main drivers of GHG emissions are growth in economic output and population, outpacing emission reductions from improvements in energy intensity • Future development pathways and energy sector will be shaped by climate change than resource depletion.

  17. MAJOR FINDINGS • Main drivers of GHG emissions are growth in economic output and population. Increased use of coal relative to many other energy sources has reversed a long‐ standing pattern of gradual de-carbonization of the world’s energy supply Growth in Economic output is the major driver of GHG emissions The decline of energy intensity of economic output has had an offsetting effect on global emissions arisen from growth in population Source: IPCC AR5, 2014
