Transports and fuels
Reducing our dependency in fossil fuels
Without new energy policies, energy demand and consequent CO2 emissions are projected to increase. Global primary energy demand by industry is projected to rise by 40% by 2030 from 2007 levels. This would put global energy-related CO2 emissions at 40.2 gigatonnes (Gt) in 2030, with an annual growth rate of 1.5% (IEA, 2009a). Such a trajectory puts the world on track for a long-term concentration of greenhouse gases in the atmosphere of over 1000 ppm of CO2 equivalent and a longer-term average temperature increase of 6 °C. This is clearly unsustainable, environmentally, socially and economically. Co-ordinated action will be needed in all energy sectors, particularly in the transport sector.
The transport sector is a huge consumer of energy (accounting for 19% of global final energy consumption in 2007) and will account for 97% of the increase in world primary oil use between 2007 and 2030. The consequent energy security and greenhouse gas emission implications of oil-dominated road transportation mean that reducing the fuel used in this sector is one of the highest priorities for all countries.
Sweden's take on sustainability in transports
These areas are trending right now in Sweden:
- City hybrid buses
- Eco driving
- Electrifying vehicles
- Biogas fueled buses and cars
- Bicycle logistics
Sweden is a world leader in water purification and bio-waste treatment.
We have solutions that increase quality drinking water supply, put less strain on groundwater sources and reduce eutrophication. Generating biogas from sewage sludge uses zero fossil fuel. Sewage treatment facilities are today the biggest biogas producers in Sweden. And as much as 50 percent of the biogas produced goes to vehicles…
Biogas is an increasing fuel of choice for Stockholm's buses and the capital has introduced a large fleet of biogas buses. To facilitate refueling, one of the bus depots has been equipped with its own filling station – with gas directly from the local waste treatment plant. The buses are known as the Stockholm green fleet.
Traffic is the main source of hazardous emissions, noise and a major source of greenhouse gas emissions in Stockholm. The city has responded to the green transport challenge by introducing the Clean Vehicles in Stockholm program, which aims to catalyze a market breakthrough for clean vehicles. After 13 years, the results are impressive. Twenty percent of cars sold in Stockholm in 2007 were clean vehicles, a figure that had risen to 35 percent just a year later. All inner-city buses operate on biogas or ethanol. The trend remains positive.
