Local Air Pollution and Global Climate Change

A Cost-Benefit Analysis

MaximumCurrent Feasible

Legislation Reductions

calculations based on:1]RAINS/Milieubalans(MNP,2005)2] 2% growth yr-1 of GDP

Dutch share of expenditures on LAP and GCC may shift dramatically

Results CBA on LAP & GCC

• Discounted LAP benefits significantly exceed those of GCC

• LAP policies alone lead to modest CO2 emission reductions, but magnify when combined with GCC policies

• LAP expenditures in EU decline from GCC policy expenditures

LAP = Local Air PollutionGCC = Global Climate ChangeCBA = Cost Benefit Analysis

MERGE model (Manne&Richels) + LAP

• Top-down economy + bottom-up energy• Intertemporal maximization of discounted utility

– Abatement "where", "when“, and "what" flexibility

• 9 regions, Pareto-efficient solutions for 2010-2150• Market and much larger non-market damages

(human health, biodiversity)

+ LAP:Restrict to primary energy related particulate matter +

precautionary assumption– 6% attributive risk of premature deaths from long-term

exposure– Value of Statistical Life at Median values (1 million euro)

LAP = Local Air PollutionGCC = Global Climate ChangeCBA = Cost Benefit Analysis

Discounted LAP benefits significantly larger than GCC benefits (ratio >> 1!!!!)

Temperature in 2150 = 4.8 0Celsius compared pre-industrial levelBaseline: Premature Deaths to PM2.5 = 108 million over 2000-2150 period

Yes, ratio betweenLAP and GCC benefits fallls in the range of 2-31

Co-benefits from LAP to GCC magnify when implementing climate policies (synergy!!!)

CO2 Emissions:

End-of-pipe abatement costs:

LAP = Local Air PollutionGCC = Global Climate ChangeCBA = Cost Benefit Analysis

Results CBA on LAP & GCC

• Discounted LAP benefits = 2-31 * GCC benefits

• LAP policies alone lead to modest CO2 emission reductions, but magnify when combined with GCC policies

• LAP expenditures in EU decline from GCC policies

• Caveat: this analysis restricts to primary PM

LAP = Local Air PollutionGCC = Global Climate ChangeCBA = Cost Benefit Analysis

Preliminary Policy conclusions

• No delay with GCC policies, but

• integrate them into LAP strategies (it is the robust option)

• Increase research to reduce uncertainty of GCC

LAP = Local Air PollutionGCC = Global Climate ChangeCBA = Cost Benefit Analysis

Further and related work

• This work: – Paper will be finalized by mid-June

• Further work: – extend LAP to include

1] Secondary aerosols (and increase the PM concentrations)

2] SO2, NOx, and NH3 emissions and abatement cost curves

• Related work: – on MNP web-site entitled “Sustainable energy: trade-offs

and synergies between energy security, competitiveness, and environment”
