Consumers can have a major impact on the world's efforts to reduce global warming, a major report has concluded.
The research is led by Professor Mohan Munasinghe, Director General of The University of Manchester's Sustainable Consumption Institute.
It estimates that if consumers are responsible for 75% of emissions and that if the developed world reduces its emissions in line with government targets, this action could lead to a 50% reduction in emissions by 2050.
The report also and calls for stimulation of consumer demand for low-carbon products and services, using a range of tools such as tax incentives, public procurement decisions and targeted marketing.
Munasinghe said: "Consumption transcends national boundaries. Businesses serve consumers, operate globally and can work quickly.
"So the opportunity is there for consumers working with, helped by businesses, to lead a green revolution that will help governments achieve more ambitious emissions reduction targets and report shows how this can be achieved.
"In the UK alone, a conservative estimate is that 60% of emissions are influenced directly or indirectly by consumers.
"But we stress say, that though consumers are fundamental to the solution, although they are often seen as part of the problem. for the same reasons they are also fundamental to the solution."
Professor Munasinghe shared the 2007 Nobel Prize for Peace with former US Vice President Al Gore and others, is Vice Chair of the United Nations Intergovernmental Panel on Climate Change (IPCC-AR4), which is the world's leading scientific body on climate change. The IPCC shared the 2007 Nobel Peace Prize with former US Vice President Al Gore.
He added: "Consumption is directly linked to greenhouse gas emissions through fossil fuel power sources, the use of carbon-based materials in manufacturing and large greenhouse gas emissions from agriculture.
"Business and Government must empower consumers by removing the many individual barriers they face when trying to make low-carbon choices.
"If we consider the countries in which goods and services are consumed, and allocate emissions accordingly, the findings are striking.
"For example, nearly 20% of China's emissions are produced on behalf of other countries. Conversely, emissions from the US would be 8% higher when counted by consumption.
"We need new and innovative solutions, because with conventional mitigation methods, people in developed countries are unlikely to accept the sort of reductions in their standards of living that would be needed to deliver emissions reductions on the required scale of 80% by 2050. Similarly, people in developing countries will not be prepared to forego the benefits of economic development in the name of mitigating climate change."
