Generally the costs of
reducing GHG emissions by saving energy are lower than by switching to alternative energy sources, in particular biofuels.
These standards will result in significant
GHG emissions reductions and fuel efficiency improvements across all of these vehicle types.
Thirty years from now, wind power might be cutting global
GHG emissions by 10 %.
Comprehensive studies that account for both direct and indirect emissions estimate that over 50 % of
global GHG emissions come from raising livestock.
«The energy sector is the largest and fastest growing contributor to climate change globally — 35 % of all
human GHG emissions come from this sector,» the call says.
Certainly, CO2 and other
anthropogenic GHG emissions are a potent driver of warming, with water serving in a feedback role due to its short atmospheric lifetime.
Not only are such investments critical to securing long - term productivity and competitiveness, research clearly shows a strong relationship between technological adoption and
lower GHG emissions.
The project reduces
GHG emissions associated with the consumption of biomass for wood fuel traditionally used to boil drinking water.
Our 2007 work, and the work in our new paper make it clear that without
GHG emissions mitigation, there is no sustainable future for polar bears or other ice dependent creatures.
The raw resource extraction, manufacturing, transportation, construction, usage, and end - of - life stages of building products each generate
significant GHG emissions.
CI takes into account the full
lifecycle GHG emissions associated with a fuel: all of the steps of producing, transporting, and consuming a fuel.
Corn is among the most intensive uses of fertilizer and represents a significant opportunity for nitrogen use efficiencies that could reduce
GHG emissions while maintaining or improving yields.
Addressing GHG emissions is clearly an important first step in ensuring the burden of climate change is not amplified in the future.
These prices do not include the cost of a backup for wind and solar require, or the costs in terms of human health or
rising GHG emissions from fossil fuels.
As this figure shows, even without accounting for the
actual GHG emissions since 1990, the warming projections are consistent with the observations, within the margin of uncertainty.
GHG emissions inventories are used by policy makers to understand sources of emissions, to develop strategies to reduce GHGs, and to track progress.
The pipeline itself is meaningless, what matters, from a climate perspective, are all the
additional GHG emissions that would be caused, directly and indirectly, by tar sand development.
The bottom line is that while achieving the
necessary GHG emissions reductions and stabilization wedges will be difficult, it is possible.
Whereas widespread agreement on a gold standard remains elusive, the present study shows that the principal
GHG emissions calculation methods produce consistent rankings within specific route - structure classes.
Also, if rapidly
declining GHG emissions are achieved, changes of solar forcing will become relatively more important.
The company also commits to reduce supply
chain GHG emissions ** by 29 % over the same time - period.
