average global temperatures rising 4 °C or more
the potential increases in temperatures due to rising gas concentrations seem higher
the physical impacts of a warming planet are appearing at a faster rate than expected.
atmospheric greenhouse gases to under 10 gigatons of CO2 -equivalent per year, compared with the current 45 gigatons(one billion tons).
leading industrialized nations are due to meet in December this year in
if they agree to cut their emissions by at least 80 per cent by 2050 compared with 1990, this will be an essential step towards meeting the challenge
The key to these major reductions in emissions - use of low-carbon technologies use of low-carbon technologies. use of low-carbon technologies.
investments in low-carbon technologies could provide sustainable and well-founded economic growth
“Investments that improve energy efficiency will also yield benefits when power and heating prices increase again during economic recovery.”
It can provide job opportunities in the short run global economic downturn could distract us from the bigger task of tackling climate change medium-term target of around 0.1 per cent of world GDP, or about $50 billion per year.
public funding for energy research and development should be doubled now from its present global level of about $10 billion per year
well-functioning global carbon market would drive these stimulate new breakthrough technologies that will lead to major cuts in emissions beyond 2030
technology needs to spread through international and public-private collaborations
scaling-up of technologies such as second-generation biofuels - which do not directly affect food production within the next 15 years
needs support for the development
by creating carbon markets in which the price of emitting carbon reflects the potential impact of those emissions, and by introducing energy-efficiency standards to incentivise innovation,
“This requires policies and measures that remove barriers and provide incentives for technological development over three timescales.”
progress needs to be accelerated costing about 2 per cent of global GDP each year Such reductions
