The 10 hottest years on record have all occurred since 1998.
Moreover, sea levels have risen in a way consistent with the warming – since 1961 at an average of 1.8 millimetres per year, and since 1993 at 3.1 millimetres per year.
The contribution of Europe, North America or Australia to GHGs is about 3 times higher than that of China, 10 times higher than that of India, and up to 100 times higher than that of Africa.
According to International Energy Agency, about ¼ of the world’s population do not have access to electricity; 83 per cent of which are inhabitants of rural areas. Only 12 per cent of sub-Saharan African rural population have access to electricity.
The estimated increase of global energy consumption is over 40 per cent between 2006 and 2030, 70 per cent of which will come from developing countries.
Newer energy efficient bulbs last up to 5 times longer and are over twice as efficient as compact fluorescent bulbs. Most of the energy used by incandescent bulbs escapes as heat, and only 5 per cent of it is turned into light.
The world’s standby products use up to 10 per cent of household energy consumption. They are estimated to cause 1 per cent of global CO2 emissions.
In a single flight from Germany to the Caribbean, around 4 tonnes of CO2 per passenger are produced. It is more than 4 times the average annual emissions of a person living in India.
Tourism is responsible for 5 per cent of global CO2 emissions. Moreover, these emissions might triple by 2035 if no action is taken. For example, long haul travels constitute 2.7 per cent of all tourist trips but they contribute 17 per cent to global tourism emissions, whereas coach and rail trips constitute 34 per cent of all trips, and they only account for 13 per cent of emissions.
The water footprint of a cotton T-shirt is 2,050 litres, a pair of leather shoes – 8,000 litres, and of a sheet of A4 paper – 10 litres.
To prevent the 2°C temperature rise by 2050, addressing this issue now would be cheaper. Using 2 per cent of the GDP, which is the total value of all goods and services produced in one country during a year, now is a better solution than spending 20 per cent of GDP later.
It is estimated that over a quarter of the world’s population has access to the internet. However, it ranges from nearly 80 per cent in North America to 10 per cent in Africa.
In 2000, 2 per cent of Africans had a mobile phone, but nearly 30 per cent had one in 2009. 66 per cent of the world’s mobile phones are in developing countries.
In the next 10 years, sales of electronic products around the world, particularly in Africa and Latin America are estimated to rise sharply. By 2020, in South Africa and China, e-waste from old computers will have jumped by 200 to 400 per cent from 2007 levels and by 500 per cent in India.
Information communication technologies (ICT) are accountable for 2 per cent of global CO2e emissions, 40 per cent of which is due to PC’s and monitors.
