Collectively, the studies make it clear that the INDCs will substantially bend the global
emissions trajectory below our current path, but still don't go far enough to limit warming to below 2 °C and avoid some of the worst climate impacts.
Collectively, the studies make it clear that the INDCs make a substantial contribution to bending the global

As a self - proclaimed «climate leader» the UK government has a critical role to play in closing the «
emissions gap» — the gap between the current global
trajectory of greenhouse gas
emissions and the actions necessary to limit warming to 1.5 ˚C and «well
below» 2 ˚C (and hence reduce the risks of disaster), they write.
This is the difference between countries» pledged commitments to reduce
emissions of heat - trapping greenhouse gases after 2020 and scientifically calculated
trajectories giving good odds of keeping global warming
below the threshold for danger countries pledged to try to avoid in climate talks in 2010 (to «hold the increase in global average temperature
below 2 °C above pre-industrial levels»).
20The modeled
trajectory attempts to impose lower carbon reductions in the early compliance years, within the constraints of maintaining the 10 - year average interim
emission performance goals, and not require any state to reduce its annual
emission performance goal
below its final 2030 target in any compliance year.
As shown in the chart
below, the LEAP model shows a «business as usual» forecast in red, the previous forecast before using LEAP in orange, historical
emissions in Oregon in blue, and the needed
trajectory to meet the 2050 goal in yellow.
If the overall cap for any year is set
below the level of
emissions last year, on a downward
trajectory compatible with stabilizing concentrations at a safe level, reserving some credits for new entrants would force other firms to bid for fewer permits, raising prices and increasing the number of mitigation activities that are worth undertaking.
In a recent post, I made the optimistic argument that, despite all the obstacles thrown up by rightwing denialism, the world is on track to reduce CO2
emissions to zero by 2050, on a
trajectory that would hold atmospheric concentrations of greenhouse gases
below 450 ppm.
The science - based targets approach is in line with the latest Intergovernmental Panel on Climate Change report which calls for a global
emission trajectory to keep global warming
below 2 degrees Celsius.
This means the Commission now has 12 months to devise a strategy for aligning the EU's
emissions trajectory to 2050 with the Paris Agreement, and hence that the process has been set in train that could ultimately at some point in the next three to five years lead to an EU - ETS cap aligned with the objective of restricting the increase in the average global temperature to «well
below 2 °C».
GHG
emission trajectories that are consistent with the goal of keeping global warming
below 1.5 or 2ºC, translate into a global carbon budget that represents a de-facto
emissions cap for the whole economy.
He parameterizes peak global CO2
emissions date, and, assuming a ceiling temperature of 2 C over pre-industrial, identifies different CO2
emissions trajectories required to keep temperature at /
below the 2 C ceiling.
