Action is needed…
Climate change by degrees
Probably unavoidable(>350 ppm CO2)
Emissions peak 2015 (400ppm CO2)
Emissions peak 2030 (450ppm CO2)
Emissions peak 2050 (550ppm CO2)
Emissions peak > 2050(>650ppm CO2)

At the moment, we are using 30% more than the Earth can
sustainably provide.Source: Global Footprint Network / Best Foot Forward
Rising to 100% by 2050 (unless we act).

Key challenges for organisations
A Case Study:
• business travel vs. video-conferencing
Client: GLA• Home-working (webcam) • Use of professional VC equipment• Compared with mixed mode business
travel
Current commuting; CO2/mode
average footprint:
422kgCO2/person
Homeworking vs. commuting(kgCO2/year)
Current business travel; CO2/mode
average footprint:
42kgCO2/person
video-conferencing vs. business travel(kgCO2/trip)
Carbon ‘break even’ point by mode (total staff business travel km/yr and VC)
Other opportunities…
• Modal switch
• Technology
• Demand management
Fortunately, there are tools to help you…

Questions/challengesWhat CO2 reductions do you think would be
‘fair’ for your operations?
What are the business implications of operating in a more resource-constrained world?
Could you reduce supply chain CO2 per unit of output by 80% by 2050?
How do you plan to sustainably manage growth?
What combination of demand management, technology & efficiency improvements will work best for you?
How can you minimise the cost per tonne of CO2 avoided?
