What is CERO?• Developed for an energy sector with large complexity:
a) travel behaviour needs to be modelled explicitly to get a bottom-up perspective of key players
b) need for tailor-made cost-benefit assessments of alternative travel policies
c) Applicable for benchmarking to spread good examples
• Engages a broad range of experts and researchers:– Statisticians– Economists– Behaviourists– Travel managers– Technical implementers
• Developed in a doctoral thesis at KTH: ”Mobility Management and Climate Change Policies”
Developed with empirical support from large organizations
Macro economic effects from 10% traffic reductions in Stockholm county
(Robèrt och Jonsson, 2006)
-750 MSEK accident costs -360 MSEK emission costs -570 MSEK in vehicle time costs
( = 1,68 Billion SEK/year)
Large organizations are important actors
Decision-makers Individuals
• Can facilitate market-oriented traffic planning
• Can utilize positive ”group mentality”
• Motivated to spread good examples
Why climate targets and travel strategies?
Travel costs and emissions walk hand i hand- Short-term cost cut potential: 200 000-500 000 Euro/1000 employees and year
- “Indirect values” of showing best practiceIT-sector, energy sector, transport sector, public authorities…
- Corporate Social Responsibility (CSR)
CERO is based on backcasting
Travel policiesMapping Target
Why backcasting?
• If we know the target, why not use it?
• Avoid “path-dependency”, focusing on current obstacles and constraints
• We might well approach a paradigmatic shift where traditional forecasting is insufficient
Target description
“X% CO2 reductions in consistency with travel cost reductions and employee acceptance”

Transforming the backcasting target
Why transforming the emission target?
• Facilitates efficiency rankings, cost-benefit analyses and follow-ups between alternative policies
• Reduces the level of “fuzziness” regarding potential emission impacts
• Helps strategic planning by keeping track on factors that might change over time (u1, u2, N, s, Y…)
Modules of tailor made 1% CO2-reductions (commute trips)
• 31 car commuters switch to public transport
• Train tickets to 4 commuters with longest commute distance
• Encourage 38 car commuters to renewable fuel cars
• Allow telecommuting at least once a month
• Offer eco-driving to at least ¼ of staff
• Encourage at least 191 car commuters with commute distance 0,5-6km to cycle
• Replace 7% of business trips by car to public transport Annual cost reduction 1,1 Mkr
• Replace 4% of business trips by car to virtual meetings Annual cost reduction 2,3 Mkr
• Replace all business trips with private car to car sharingCosts unchanged
• Replace 2% of aviation trips abroad to virtual meetings Cost reduction 540.000 kr
• Replace 3% av domestic aviation to trainCost reduction 215.000 kr

Climate compensation as a last step…
+ Could increase profitability from emission reductions
- Could pacify good local initiatives and ideas
