UK, China Collaborate on Low Carbon Cities
By Sunny Lewis
BEIJING, China, November 25, 2015 (Maximpact News) – Researchers from universities in China and the United Kingdom are putting their heads together to reduce carbon emissions from cities in both countries.
Four newly funded research projects aim to develop an overall understanding of current buildings, mobility and energy services to help urban planners lower climate-changing carbon dioxide (CO2) emissions while keeping residents comfortable and moving efficiently.
One new project is directed towards integrating low carbon vehicles, such as electric cars, into urban planning.
The other three will tackle existing buildings to provide energy efficient lighting, heating and cooling, as well as indoor environmental quality.
Meeting the pressing carbon emission reduction targets expected to emerge from the upcoming Paris climate talks will require a major shift in the performance of buildings, say scientists in both countries.
The projects were announced as Chinese President Xi Jinping visited the UK October 20-23.
The UK will spend over £3 million from the Engineering and Physical Sciences Research Council (EPSRC), and China will contribute equivalent financial resources from the National Natural Science Foundation of China (NSFC).
EPSRC’s chief executive Professor Philip Nelson, a Fellow of The Royal Academy of Engineering, said, “The aim of this UK-China research collaboration will be to reduce worldwide CO2 [carbon dioxide] production and ensure energy security and affordability.
“The projects build on the strength of our internationally renowned research and will benefit both the UK and Chinese economies,” said Nelson.
Professor Che Chengwei, deputy director general of NSFC’s Department of Engineering and Material Sciences, said, “NSFC has been working closely with EPSRC for several years to address challenges related to achieving a low-carbon economy.”
“This latest programme, with a focus on future urban environments, will build substantially stronger links between Chinese and UK research communities in relevant areas,” said Che. “It will also brighten the future bilateral collaboration between both countries.”

The four funded projects are:
- Low Carbon Transitions of Fleet Operations in Metropolitan Sites to be researched at Newcastle University (NCL), Imperial College London, and Southeast University (SEU)
Low carbon vehicle fleets for personal mobility and freight could contribute to reducing the climate impact of urban transport and improve local traffic and air quality conditions.
But uncertainties remain on the demand for fleet services and effective fleet operations, especially for electric vehicles, where interaction with the power grid becomes a critical issue.
A range of new business models for the operation of urban freight and fleet services are emerging, enabled by new information and communications technologies.
This will provide an integrated planning and deployment strategy for multi-purpose low carbon fleets. It will devise operational business models for maximum economic viability and environmental effectiveness.
- City-Wide Analysis to Propel Cities towards Resource Efficiency and Better Wellbeing, to be researched at University of Southampton and Xi’an University of Architecture & Technology
This project is focused on two cities – Xi’an, China and Portsmouth, UK, both known for their cultural heritage and their population density.
On the southern coast of England, Portsmouth, population 205,000, is the densest city in the UK. Landlocked Xi’an in central China has a population of 5.56 million.
Both cities have published ambitious plans for reducing city-wide carbon emissions but both have lots of aging buildings and infrastructure. The project focuses on the likely impact of building refurbishments on human wellbeing and on carbon emissions.
The researchers will gather real energy use information through sensor deployments and surveys of building residents to identify low disruption and scaled-up retrofit methods.
They will model neighborhood and district retrofits and systems integration, including building refurbishment, district energy and micro-generation to improve buildings for their users.
They are expected to identify smart solutions that will reduce energy consumption and meet mobility needs while pursuing carbon reduction targets.
- The Total Performance of Low Carbon Buildings in China and the UK, to be researched by University College London (UCL) and Tsinghua University
The potential unintended consequences of the inter-linked issues of energy and indoor environmental quality (IEQ) present a complex challenge that is gaining increasing importance in the UK and in China, these researchers say.
They will address the total performance of buildings to reduce the energy demand and carbon emissions while safeguarding productivity and health.
This project will address the policies and regulatory regimes that relate to energy/IEQ, the assessment techniques used and the ways that buildings are utilized.
An initial monitoring campaign in both countries will compare the same types of buildings in the two contexts and how energy/IEQ performance varies between building type and country.
Researchers will assemble a unique database relating to the interlinked performance gaps. They can then develop semi-automated building assessment methods, technologies and tools to determine the most cost-effective route to remedy the underlying root causes of energy/IEQ under performance.
A second stream of work will address the unintended consequences of decarbonizing the built environment, research already taking place at the University College London.
- Low carbon climate-responsive Heating and Cooling of Cities, to be researched by the University of Cambridge, University of Reading and Chongqing University
This project focuses on delivering economic and energy-efficient heating and cooling to city areas of different population densities and climates.
It confronts ways of offering greater winter and summer comfort within China’s Hot Summer/Cold Winter climate zone while mitigating vast amounts of carbon emitted by burning fossil fuels for heating and cooling.
It concentrates on recovering value from the existing building stock of some 3.4 billion square meters, where more than half a billion people live and work.
The cross-disciplinary team of engineers, building scientists, atmospheric scientists, architects and behavioral researchers in China and UK will measure real performance in new and existing buildings in Chinese cities.
They will investigate the use of passive and active systems within integrated design and re-engineering to improve living conditions and comfort levels in the buildings.
The researchers will compare their findings with existing UK research examining the current and future environmental conditions within the whole National Health Service (NHS) Hospital Estate in England to find practical economic opportunities for improvement while saving carbon at the rate required by ambitious NHS targets.
They will propose detailed practical and economic low and very low carbon options for re-engineering the dominant building types and test them in the current climate with its extreme events.
To ease China’s adaptation, recently published research “Air Pollution in China: Mapping of Concentrations and Sources” shows that China’s carbon emissions have been substantially over-estimated by international agencies for more than 10 years
From 2000-2013 China produced 2.9 gigatonnes less carbon than previous estimates of its cumulative emissions.
The findings suggest that overestimates of China’s emissions during this period may be larger than China’s estimated total forest sink – a natural carbon store – in 1990-2007 (2.66 gigatonnes of carbon) or China’s land carbon sink in 2000-2009 (2.6 gigatonnes of carbon).
Published in August in the journal “Nature,” the revised estimates of China’s carbon emissions were produced by an international team of researchers, led by Harvard University, the University of East Anglia, the Chinese Academy of Sciences and Tsinghua University, in collaboration with 15 other international research institutions.
Low Carbon Cities forms part of the Low Carbon Innovation programme, a £20 million three-year investment announced in March 2014.
Facilitated by Research Councils UK (RCUK) China, the first team established outside Europe by the UK Research Councils, this programme builds on five years of collaborative energy research funded jointly by China and the UK.
To date, RCUK China has provided over £160 million in co-funded programmes, supporting 78 UK-China research projects that have involved more than 60 universities and 50 industry partners in both countries.
