80% Reduction in Current Levels of Building Sector Emissions by 2050
The general scientific consensus is that in order to maintain global carbon
dioxide levels at less than twice pre-industrial levels, carbon dioxide emissions
would need to be reduced by 80% below the levels of the year 2000 by
CO2 concentrations in excess of 500 ppm are feared to give rise to
unmanageable global warming. "Unmanageable" means global warming
cannot be mitigated or adapted to and, as John Holdren, Director of the White
House Office of Science and Technology Policy, has said, the only alternative
is to suffer.
To put the magnitude of this challenge in perspective, in spite of
projected floor space increases of 150%, total building sector emissions in 2050
will need to be only 20% of their current levels.
