Analyzing population and employment sizes at the local finer geographic scale of transit station areas offers valuable insights for cities in terms of developing better decision-making skills to support transit-oriented development. Commonly, the station area population and employment have been derived from census tract or even block data. Unfortunately, such detailed census data are hardly available and difficult to access in cities of developing countries. To address this problem, this paper explores an alternative technique in remote estimation of population and employment by using building floor space derived from an official administrative geographic information system (GIS) dataset. Based on the assumption that building floor space is a proxy to a number of residents and workers, we investigate to what extent they can be used for estimating the station area population and employment. To assess the model, we employ five station areas with heterogeneous environments in Tokyo as our empirical case study. The estimated population and employment are validated with the actual population and employment as reported in the census. The results indicate that building floor space, together with the city level aggregate information of building morphology, the density coefficient, demographic attributes, and real estate statistics, are able to generate a reasonable estimation.

CASBEE-City tool determines the city’s Built Environment Efficiency (BEE) by calculating the improvement of Quality of Life (Q) over human activities’ Environmental Load (L) within the city’s hypothetical boundary. A total of 58 variables (57 Q indicators and one variable for L) are used in the worldwide version of CASBEE-City which were grounded using ISO 37120:2014 Sustainable Development of Communities and 17 Sustainable Development Goals (SDGs) by the United Nations (UN). This paper examines the application of CASBEE-City for Malaysian cities using the case of Johor Bahru City and identifies assessment indicators which are customised based on the data availability, reliability and suitability through focus group discussions (FGDs) which involved 36 respondents (researchers, urban planners and stakeholders). This paper reveals Johor Bahru with moderate score B+ in 2010 and 2025. Consensus were also achieved from the 36 FGD respondents for the practicability and future potential of CASBEE-City and BEE framework in Johor Bahru.

This paper outlines the lessons learnt through the multidisciplinary ‘Science-to-Action’ approach to formulating, mainstreaming and implementing the Low Carbon Society Blueprint for Iskandar Malaysia 2025 (LCSBP-IM2025). Iskandar Malaysia (IM) is a rapidly developing urban region in southern Peninsular Malaysia that was institutionalised in 2006 with a view to spurring Malaysia’s economic growth up to 2025. In pursuing rapid economic growth to become a developed, high-income nation by 2020, Malaysia is conscious of its global responsibility in environmental protection and global climate change mitigation, hence the country’s commitment to reducing its carbon emission intensity of GDP by up to 40 % by 2020 based on the 2005 level. Being a premier economic region in Malaysia, IM seeks to develop a low carbon society (LCS) and lead the way to cutting its carbon emission intensity by up to 58 % by 2025 based on the 2005 level through the implementation of the LCSBP-IM2025. The LCSBP-IM2025 is the outcome of an internationally funded joint research under the SATREPS programme that brings together Universiti Teknologi Malaysia (UTM), Kyoto University, Japan’s National Institute for Environmental Studies (NIES), Okayama University and the Iskandar Regional Development Authority (IRDA), in a unique ‘academia-policymaker’ partnership, towards crafting an LCS pathway to guide and sustainably manage the projected rapid development in IM up to 2025. To that end, a multidisciplinary research team that comprises the above research institutions and IRDA, led by UTM, has been set up. A methodology has been developed to formulate IM’s future LCS scenarios, propose LCS actions to achieve the LCS scenarios, quantify the GHG emission reduction potential of the proposed LCS actions and continuously engage local stakeholders in a series of focus group discussions (FGDs). The project has been a great success from its official commencement in July 2011, which saw the LCSBP-IM2025 being launched at UNFCCC’s COP 18 in Doha in November 2012 and officially endorsed by the Malaysian Prime Minister in December the same year. In November 2013, the Iskandar Malaysia Actions for a Low Carbon Future was launched, outlining ten priority projects selected from the LCSBP-IM2025’s 281 programmes for implementation in IM in 2013–2015; the projects are now at various stages of implementation, yielding real impacts on IM’s progression towards its LCS goal. The project offers valuable lessons especially in advancing scientific research on LCS into policymaking and, importantly, into real actions (hence, Science to Action). These include the importance of having strong highest-level government support, aligning LCS actions to higher-level development priorities, taking policymakers on-board the research team, continuously actively engaging local communities and stakeholders through FGDs and overcoming science-policy and disciplinary gaps that emerged. What is clearly evidenced by the LCSBP-IM2025’s success is that developing countries, with good synergy between highly committed local research institutions and policymakers, subject to adequate international funding and technological assistance from developed nations, are capable of crafting and putting in place implementable LCS policies that eventually contribute to mitigating global climate change through real cuts in GHG emissions while still achieving a desired level of economic growth.
