Urban policies which include energy and environmental objectives are seen as potentially effective instruments in the quest for urban sustainability. Recent consensus is that the modern city region forms an important focal point for assessment and implementation of energy strategies, facilitating practical solutions to local problems as well as providing beneficial additions to national policies. Reducing the carbon intensity of economies both prevents environmental degradation and supports the regional economy in the medium to long term. The authors look at the construction of a CO2 inventory for the Greater Manchester region, an urban conurbation set for economic growth after recent restructuring and diversification. The authors argue that, by providing an indication of the localised carbon flows specific to the region, it is possible to target problem areas, prioritise carbon-reduction strategies, and recommend policies that will case the transition to a more sustainable urban settlement. The increased focus on finding ‘local’ solutions to the reduction of carbon intensity has coincided with privatisation of much of the energy industry. The newly competitive energy market conflicts with the shift to local-scale evaluations and has resulted in energy details at the regional level becoming increasingly harder to obtain. The problems experienced in the construction of this inventory will be common to other cities in the United Kingdom and will have to be addressed if the ‘local’ approach is to be as effective as is hoped.

The perceived threat of 'enhanced' global warming has become a widespread public concern since the late 1980s, with the balance of informed opinion urging world-wide collaboration on combating the causes of global warming. The increasingly globalised status of the majority of late twentieth century economies ensures that remedial action will ultimately require a degree of international cooperation. Although the formulation of environmentally friendly energy policies, including carbon reduction strategies, can be framed at international and national levels, recent trends are for CO2 reduction measures to be instigated by regional, or local, authorities.This paper focuses on the city-region of Greater Manchester, U.K., and reviews both existing and potential energy supply options for reducing regional CO2 emissions, highlighting the benefits and obstacles facing carbon reduction measures implemented at a 'local' scale1. Mitigation action at this level is considered desirable as remedial measures have most chance of success when accompanied by the supportive involvement of local people.

In recent decades, climate change, mostly caused by CO2 emissions, has become a critical issue of concern to people worldwide. It is necessary for countries all around the world to reduce carbon emissions. China, as the world’s largest carbon emitter, is under great pressure to implement carbon-reduction strategies. Technological progress plays a crucial role in balancing environmental and economic development. The main objective of this work is to empirically compare the effects of government and enterprise research and development (R and D) on carbon-emission reduction using the panel data of 30 Chinese provinces from 2009 to 2016. The effects of both government and enterprise R and D investment on carbon intensity are compared in detail through a linear model and a threshold-regression model. Linear-regression results shows that both government and enterprise R and D decrease carbon intensity, while enterprise investment tends to be more instant. Further threshold-regression results indicate that the effects of government and enterprise R and D on carbon intensity are different in different urbanization stages. Guiding enterprises to invest in R and D in medium-developing areas, and increasing government support and subsidies for R and D activities in underdeveloped areas should be an important goal of the government policies.

Greater Manchester, an urban conurbation in the UK, was the birthplace of the industrial revolution. Recent restructuring and the potential for increases in economic growth place a requirement on the city to consider its future energy strategies if it is to keep its CO2 emissions to responsible levels. Reducing the carbon intensity of economies is an essential element of combating the threat of global warming, and although the problem is global in nature, effective remedial action has to be instigated at a variety of spatial scales. Inventories that are based at the city level allow the intensity and distribution of local carbon flows to be calculated and therefore have considerable potential in many planning and decision making processes. The CO2 inventory constructed for this paper is the first stage of prioritising carbon reduction strategies for Greater Manchester, providing an indication of carbon flows specific to the region. The inventory has been developed from the knowledge and experience of other city-scale energy studies which have taken place to date, and although the methodology has been developed for application to the Greater Manchester region the approach can be replicated for other urban areas.

Sustainable manufacturing is increasingly being recognized as the direction for technological innovation and implementation in industry. However, to measure and guide technology conceptualization, development, and deployment decisions, a quantifying indicator that is easy to understand is required. The carbon footprint (CFP) is found to be an effective indicator, as its value reflects essential elements of sustainability in manufacturing: materials, energy, and waste treatment. The existing standards provide a general framework to guide CFP quantification but lack explicit formulas for easy adoption. This paper presents an algorithmic approach that aims to granularize the emission source to streamline CFP quantification. This approach pinpoints the direct and indirect contributions and the respective task owners, decentralizes the responsibilities in data collection, and ascertains the degree of control to set realistic targets for CFP reductions. A case study is carried out in a manufacturer of sheet metal parts. Results show that indirect emissions from materials, energy, and transport collectively contribute 27% of product CFP.With the algorithmic approach, carbon reduction strategies can be formulated by setting priorities and realistic targets and then delegating to the task owners the reduction of the CFP of their respective areas. The current work establishes a base that can help companies to adopt CFP quantification and formulate carbon reduction strategies.

China will strive to achieve carbon peak by 2030 and carbon neutralization by 2060 cooperating with the system dominated by carbon intensity control and supplemented by total carbon emission control. This paper analyzes the environmental efficiency index of China; the empirical results show that the average growth rate is 4.5% from 2006 to 2017. A further decomposition of changes on scale efficiency and pure technical efficiency indicates that the pure technical efficiency maintains a long-term growth, and scale efficiency shows a fluctuant tendency. The abovementioned changes show that various methods in China such as industrial structure adjustment and promotion of the development of high and new technologies have obtained a certain effect. From the perspectives of regional differences, the average changes of environmental efficiency in eastern, central, and western regions as well as most of provinces and cities are all on the increase. On the space layout, a trend has been presented that the average changes in central regions exceed those in eastern regions, while the average changes in western regions are comparatively lower than those in eastern regions.

Public participation in governance is regarded as a key element in enhancing urban sustainability. While there is a wealth of participation efforts in Indian cities, there are inadequate processes for regular, inclusive, egalitarian, informed and well-structured democratic participation that provide a real say to citizens in public decision-making. ‘Deliberative democracy’ has emerged as one way to improve effective public participation in decision-making, though it is mostly prevalent in developed countries. An action research initiative was implemented over several years in Pune, India. It used mixed methods to introduce and assess the applicability to the Indian urban context of high-quality public deliberations. This article presents a case study of a deliberative democracy initiative, framing the transformative public involvement needed to address sustainability problems. It also shows how the integration of the mixed methods approach in the action research to design and facilitate deliberative participation processes, helped to broaden and deepen understanding, and enhanced the transformative capacity of the research design.

An explicit spatial carbon emission map is of great significance for reducing carbon emissions through urban planning. Previous studies have proved that, at the city scale, the vector carbon emission maps can provide more accurate spatial carbon emission estimates than gridded maps. To draw a vector carbon emission map, the spatial allocation of greenhouse gas (GHG) inventory is crucial. However, the previous methods did not consider different carbon sources and their influencing factors. This study proposes a point-line-area (P-L-A) classified allocation method for drawing a vector carbon emission map. The method has been applied in Changxing, a representative small city in China. The results show that the carbon emission map can help identify the key carbon reduction regions. The emission map of Changxing shows that high-intensity areas are concentrated in four industrial towns (accounting for about 80%) and the central city. The results also reflect the different carbon emission intensity of detailed land-use types. By comparison with other research methods, the accuracy of this method was proved. The method establishes the relationship between the GHG inventory and the basic spatial objects to conduct a vector carbon emission map, which can better serve the government to formulate carbon reduction strategies and provide support for low-carbon planning.
