UK research shows that without active mitigation against the current level of emissions, the world's temperature will rise by 4 degrees by the end of the century compared to the pre-industrial level. That would mean 23% of China’s population deprived of the dry season glacier melt, making water scarcity far more severe than it is even today. It would mean a decrease in rice yield of up to 30% would be likely. Sea levels could rise by 0.9 metres.
The UK, starting from the Industrial Revolution, pursued rapid development. It was only later that we turned to sustainable development. China, now the world's biggest emitter, is working on both in parallel. This is to be praised.
Developed countries recognise their historic responsibility and need to take the lead in combating climate change. The UK was the first country to introduce legally-binding carbon budgets. These commit us to carbon savings of 34% by 2020 and at least 80% by 2050 against a 1990 baseline. The UK's per capita emissions, now 10 tonnes per annum, may fall below China's, now 6 tonnes per annum but rising, by around 2016. Our policies and work to combat climate change in the UK are transforming how we generate power and use it in our homes, businesses, transport and public services, and are creating new jobs and industries for a low carbon economy.
Unlike Europe, most of the homes, offices, power stations and infrastructure that will exist in China in 2030 have not yet been built. This means China's capacity for green growth and innovation is potentially enormous.
China has adopted a stretching target between 2006-10 to improve energy intensity by 20%. By 2020 it plans for 15% of its total energy mix to come from renewables and nuclear. Its solar, wind, hydro and nuclear industries are developing rapidly. Forest cover is to be 20% by 2010 and 23% by 2020 (from just 9% in 1949). In 2008 President Hu committed China to a low carbon economy. China's leaders see the harmful economic effects of climate change. China's middle class, now about 80 million, want a better city environment. In July this year, China agreed at an international meeting that it would take action between 2005 and 2020 to ensure a meaningful deviation from business as usual in its emissions and committed to the goal of limiting global temperature increases to no more than 2 degrees from pre-industrial levels.
