The world can enjoy higher standards of living and more travel, while drastically cutting emissions to avoid dangerous climate change but only with sweeping changes to our infrastructure, the natural world and agriculture, a new analysis has found. <\/p>\n
The UK government analysis also assumes that billions of people will remain in dire poverty at mid-century, despite efforts to lift them to greater prosperity, as the population rises to an estimated nine billion people. <\/p>\n
Dealing with greenhouse gas emissions will require a transformation of electricity generation, including an expansion of renewable energy and nuclear power, as well as more public transport and changes to the built environment, according to the key findings of the Global Calculator, an online software tool developed by the Department of Energy and Climate Change (Decc), with partners. <\/p>\n
The calculator is intended to show the likely outcomes of a variety of choices that policymakers and the public can make to tackle global warming, such as investing in nuclear, insulating houses, making electrical appliances more efficient and using electric vehicles. <\/p>\n
Some of the findings are likely to be controversial. The analysis suggests that to cope with the food demands of a rising population, much more land will need to be brought under cultivation, which could have harmful side effects on biodiversity, and genetically modified crops may be needed to boost yields. <\/p>\n
Far more intensive agriculture will be necessary, with the amount of beef raised in confined systems vast cattle warehouses in which the animals rarely or never see grass accounting for as much as 15% of the global herd by mid-century. Consumers must also switch away from eating beef to poultry and vegetables. <\/p>\n
The analysis also found that deforestation must be halted and the extent of forested land increased by between 5% and 15% by 2050 a mammoth task, given the failure of efforts so far to halt forest destruction. <\/p>\n
However, the analysis depends on several key factors. For instance, within the emissions limits required to hold global warming to less than 2C above pre-industrial levels, in theory it ought to be possible for everyone in the world to travel 12,400 KM a year, up from an average of 8,300 KM a year at present. <\/p>\n
Currently, people in the US travel an average of 16,000 KM a year, and in the EU about 10,000 KM, while the average Indian travels 6,000 KM and Chinese less than 2,000 KM a year. So the increases in air travel in the developed world seen in recent years, thanks to the proliferation of cheap flights, will have to be severely limited in future to stay within these levels. <\/p>\n
Similarly, nutrition that fulfills our daily needs, of 2,100 calories a day, is possible for the entire planet, but is unlikely to reach everyone without a transformation in global equity. According to the models used to develop the calculator, billions of people are likely to remain in poverty at mid-century, and they are unlikely to benefit much in the form of the better nutrition, better housing or increases in travel which are theoretically possible. <\/p>\n
