We exceed our ecological footprint: In 2001, the South West residents' ecological footprint was 27.4 million gha (global hectares) or 5.56 gha per person. The earth-share is 1.9 gha per person. How we use and share the one planet we have. ecological footprint

“ Warming of more than 1 0 C above today’s level will make the Earth warmer than it has been in a million years”. Dr. James Hansen, NASA GISS
“ Business-as-usual, with fossil fuel CO 2 emissions continuing to increase will mean an additional warming of 2 0 C to 3 0 C this century and will make the Earth a different planet.” Dr. James Hansen, NASA GISS
“ At 2 0 C to 3 0 C the new equililibrium sea level is approximately 25 meters (80 feet) higher than today. Real world data suggest sea level changes in centuries rather than milenia.” Dr. James Hansen, NASA GISS
“ Action must be prompt, otherwise CO2- producing infrastructure will be built within a decade that will make it impractical to keep further warming under 1 0 C ”. Dr. James Hansen, NASA GISS

Thanks to a great crash programme in 2010 , a point of self reliance in energy is achieved through a 50% reduction in energy consumption and a massive scaling up of renewables to provide the remaining 50% Rob Hopkins, Transition Handbook
In 2014 , the Local Passiv Haus became the standard for all domestic building.
Use of local bio materials
No space heating input – other than solar and occupants body heat
In excess of 80% materials sourced locally
Rob Hopkins, Transition Handbook
Education in 2008 was woefully adequate, given the scale of tranistion to come. A new ciricumulm was approved in 2012 firmly based on foundations of sustainability and resilience building By 2018 universities were no longer to attract from wide geographical areas, following a rethink, they are now incubator centers for local business and skills Rob Hopkins, Transition Handbook
Beyond Zero Energy for ‘free’? Data centers could heat 70,000 homes The energy we waste using bottled water would be enough to power 190,000 homes. Passiv Haus Cement waste
