In developing and emerging economies, slowing the rate of growth of using conventional transport modes with relatively high ‐ carbon emissions for passenger and freight transport by providing affordable, lowcarbon options could play an important role in achieving
global mitigation targets.

The underlying principle guiding international negotiations continues to work towards agreeing a long term
global target to limit warming to 2 °C — and working backwards to divide up and distribute
mitigation burdens in meeting that
target.
As temperatures rise due to
global warming, she believes that study findings present health care professionals with an opportunity for
targeted interventions and policy makers with the need to develop
mitigation strategies to protect those most vulnerable to heat.
A large ensemble of Earth system model simulations, constrained by geological and historical observations of past climate change, demonstrates our self ‐ adjusting
mitigation approach for a range of climate stabilization
targets ranging from 1.5 to 4.5 °C, and generates AMP scenarios up to year 2300 for surface warming, carbon emissions, atmospheric CO2,
global mean sea level, and surface ocean acidification.
To avoid the most dangerous consequences of anthropogenic climate change, the Paris Agreement provides a clear and agreed climate
mitigation target of stabilizing
global surface warming to under 2.0 °C above preindustrial, and preferably closer to 1.5 °C.
«Combined with information on vulnerability and exposure, it serves as a scientific basis for assessment of
global risk from extreme weather, the discussion of
mitigation targets, and liability considerations,» the researchers concluded.
By committing to
targets for emissions cuts and financing for developing countries for
mitigation, forest protection and adaptation, G8 countries can build trust and confidence and lead the way on
global climate action - both for the MEF as well as for the UN negotiations which will culminate in Copenhagen in December.
Stern is referring to an eventual
target of a
global figure of one tonne emissions average per person per year, a reduction of 80 % by developed countries by 2050, and assumes all countries will join in with varying degrees of carbon
mitigation (this was before the Copenhagen summit).
[In 2001, scientists at Princeton's Carbon
Mitigation Initiative became famous for proposing a set of «climate stabilization wedges» — efficiency, wind, solar, etc. — to bring emissions down beneath
global targets.]
Scale makes a difference, and in the context of a true
global emergency transition, domestic reductions within wealthy countries, even difficult reductions, would become extremely difficult to pass up as the pressures of stringency increase and
mitigation opportunities in the South become as costly as those at home, as they eventually would under any even plausibly adequate
target.
First, the emissions
mitigation targets that the nations have tabled (but will as a technical matter only submit formally by January 31, 2010) will not get us on the path to the accord's stated objective of avoiding a
global temperature rise of more than 2 degrees Celsius, unless they are miraculously strengthened over the next 5 weeks.
In most models that show the world reducing emissions enough to hit the 2 °C climate
target, «solar energy emerges only as a minor
mitigation option» — around 5 to 17 percent of
global electricity supply in one representative study used by the Intergovernmental Panel on Climate Change (IPCC).
The issue, the study notes, is that «how much
mitigation is needed in agriculture to meet a
global target versus how much is feasible remains poorly understood.»
How much of a problem is delayed participation by developing countries in terms of raising the overall burden of
global mitigation costs, and what does this imply for appropriate near - term emissions pricing goals for the United States, if eventual
targets for
global stabilization are still to be met?
Economists and climate scientists have developed a number of models to estimate
global emissions prices that are consistent with ultimately stabilizing atmospheric CO2 concentrations at these
target levels and minimizing the
global burden of
mitigation costs over time.
For example, the management of any
global biodiversity conservation goal through the
mitigation hierarchy could follow a similar framework to the United Nations» management of carbon emissions, with nation states setting their own national goals and
targets that then sum to achieve overarching planetary goals.
However, the researchers point out that using solar geoengineering to hold
global warming to 1.5 C would not have the same environmental effect as reaching the
target using
mitigation.
And yet, those who want stringent climate
mitigation say the Paris
targets are only approximately one - third of what is needed to allegedly keep
global warming in check.
The rapid growth of carbon footprints in wealthy countries led to concerns about carbon leakage — where climate
mitigation policies in one country lead to increases in CO2 emissions elsewhere — and industrial competitiveness, because international
mitigation targets were slated to apply to developed countries and not the
Global South.
Let's see how the pledges of the big three stack up against
global mitigation curves calculated for 66 % chances of staying below 2 and 3 degree C
targets:
Although emissions reduction
targets are at the core of the Paris Agreement, the Paris Agreement also includes a
Global Stocktake Process for evaluating global progress towards the goals of the agreement and for identifying new mitigation opportunities and, over time, strengthening the nationally determined contributions (
