Compare with: adaptation: the process of adjustment to actual or expected climate and its effects, geoengineering: the deliberate large-scale manipulation of the planetary environment to counteract anthropogenic climate change. Why do we need to consider mitigation: may not be able to adapt to rapid climate change, adaptation to all climate change might be too expensive. What causes changes in emissions: the kaya identity, total co2 emissions = ci ei gpp. Ci = carbon intensity (emissions/energy: ei = energy intensity (energy/gdp, gp = per-capita gdp (gdp/population, p = population, the kaya identity was developed by japanese energy economist yoichi kaya. It identifies which economic and social factors are driving increases in carbon dioxide emissions. O to de(cid:272)(cid:396)ease e(cid:373)issio(cid:374)s (cid:449)e (cid:374)eed: more rapid improvements in energy intensity, more rapid improvements in carbon intensity, more carbon-free energy.
