Today, most of the world’s population lives in urban areas. Cities are responsible for the major share of total global energy consumption and account for most of the world’s buildings. They thus offer great potential for low-carbon transport, energy-efficient buildings and reduced electricity consumption. A great deal can be achieved here across a small area, for high levels of consumption offer major opportunities. Cities will thus play a key role in determining whether the global temperature rise can be kept below 2° C. Many are already committed to climate action. A key role for cities 25% saving on electricity bills Cape Town – solar water heater programme The South African city is promoting the installation of solar water heaters. It aims to have 200,000 in operation by 2017, greatly reducing costs to the consumer. 2014 WORLD POPULATION: ≈ 7.2 BILLION Stockholm - low-carbon growth Sweden’s capital shows that economic growth does not necessarily mean higher emissions. Stockholm cut its CO2 emissions by 35 per cent between 1993 and 2010, while the economy grew by 41 per cent. Hangzhou – pedal power The Chinese city of Hangzhou, which has a population of more than three million, has launched a large- scale bicycle hire scheme: 78,000 bikes are available at 2,000 hire stations and new ones are being added all the time. 400,000 people use the scheme every day. No charge is made if the bicycle is borrowed for less than an hour. Rural population 46% Urban population 54% 2050 WORLD POPULATION: ≈ 9.2 BILLION The urban population is growing, while the rural population is shrinking in relative terms. This trend is likely to drive up energy-related CO2 emissions: urban areas are already responsible for 70 per cent of these emissions. Rural population 34% Urban population 66% 199319972001 20052009
