In this paper, we argue that the intellectual property (IP) management of publicly developed technology serves insufficiently the imperatives of climate change mitigation, which are understood to demand most efficient dissemination of environmentally sound technology (EST), and its development. Firstly, we outline some of the criticism of IPR for climate change mitigation. Then we explain the crucial role of public funding for EST by discussing economic theory of innovation based on the writings of Joseph Schumpeter and Mariana Mazzucato, and focus on the way in which the intellectual property rights (IPRs) of publicly funded EST have been managed in the most important areas of state innovation: public procurement for innovation (PPFI), the EU Pilot Horizon 2020 and university research. We outline the perceived problems with IP management of EST and where possible try to outline changes which could, in our view, provide a viable alternative to often proposed changes to the global IP regime in regard to climate change.

The chemical manufacturing industry is one of the main contributors to the Malaysian economy and has been reported to have sustainability issues which may affect the sustainability of the nation if proper green practices have not been taken by the industry. This paper aims to study the effects of sustainable procurement on corporate sustainability performance with the moderating role of organisation age. Drawing data from 130 Malaysian chemical manufacturing organisations, the model studies the moderating role of organisation age on sustainable procurement and the corporate sustainability performance of the organisations. Partial least square (PLS) analysis is used in this study in order to analyse the data and the multistage sampling technique has also been used in this study. The results show that there is a positive relationship between sustainable procurement and corporate sustainability performance and organisation age does not moderate the effect of sustainable procurement on corporate sustainability performance.

The manufacturing sector faces sustainability issues which lead to negative consequences to the economic, environment and social sustainability performance of the sector. Cleaner production and resource efficiency which involve the use of green technology is one of the important green practices in achieving corporate sustainability performance. The objective of this study is to examine the effects of cleaner production and resource efficiency on corporate sustainability performance with the moderating role of organisational size. Drawing data from 130 Malaysian chemical manufacturing organisations, the model studies the moderating role of organisation size on cleaner production and resource efficiency and corporate sustainable performance of the organisations. The data are analysed using partial least square (PLS) analysis. The results suggest that cleaner production and resource efficiency are positively related to corporate sustainability performance. The findings also indicate that organisation size moderates the effect of cleaner production and resource efficiency on corporate sustainability performance.

Malaysia aims to reduce CO2 emissions intensity by up to 45% by 2030 based on its 2005 levels. This paper presents an analysis on optimal CO2 emissions reduction in Malaysian road transport sector using a linear programming CO2 minimisation model. Sensitivity analysis was also applied to investigate the effects of mitigation measures such as low carbon fuels, fuel efficiency improvement, travel demand management, and integrated mitigation strategies on CO2 emissions. The results demonstrated that the optimal CO2 emissions in the road transport sector could be reduced by only 2.8% (1.14 Mtons CO2) in a year. However, a reduction of up to 40% (16.44 Mtons CO2) could be achieved if integrated mitigation measures were implemented. Moving forward, Malaysia should intensify the ongoing efforts and promote fuel efficiency and green investment to achieve the intended CO2 emissions reduction.

This study aims to measure the corporate environmental reporting (CER) practices of Malaysian environmentally sensitive public listed companies based on measurement approach named strategically-framed environmental disclosure index. The content analysis technique based on a measurement index related to firm's environmental strategies has been employed. The CER practices of 209 Malaysian environmentally sensitive public listed companies are examined for the years 2010 and 2014. Results suggest that there are three types of firm behaviour in CER in response to institutional pressures: 1) 'negative deviance' (i.e., non-compliance environmental strategies leading to no quality environmental disclosures); 2) 'conformance' (i.e., compliance environmental strategies leading to low quality environmental disclosures); 3) 'positive deviance' (beyond-compliance or proactive environmental strategies leading to high quality environmental disclosures). This index shed light whether the environmental, social and governance (ESG) practice in Malaysian and global context as a deviance or normative behaviour. Moreover, this study identified whether mandatory reporting requirement force firm to actually improve environmental performance concurrently with pro-environmental policies or just as their greenwashing mechanism.

Several epidemiological studies have found associations between turbidity in drinking water supplies and acute gastrointestinal illness, although these results have been controversial. This project sought to critically evaluate these epidemiological studies through a workshop of multidisciplinary subject matter experts. Pre- and post-workshop surveys were conducted to assess any changes in opinion occurring after the one-day workshop where issues identified in the literature review were discussed. Changes were mostly small, non-significant shifts toward less favourable views of the studies. The only significant change was a shift weak agreement to weak disagreement with the statement that more should be done to ensure US drinking water quality. Responses to questions differed significantly by affiliation, discipline, and by role in the study. The survey results indicate that the workshop did not produce consensus among the participants. The survey provided a means of documenting differences in opinions expressed by all workshop attendees.

This study aims to investigate total coliform (TC) and thermotolerant coliform (TTC) removal efficiency of the waste stabilisation ponds (WSPs) system in Central India through the dispersed flow regime. To accomplish this, coliform (TC and TTC) die-off coefficient (Kb) was estimated for each pond (anaerobic, facultative and maturation) by the dispersed flow regime. Maximum Kb value was observed for the maturation pond (Kb, 5.8) in comparison to the facultative (Kb, 5.6) and anaerobic ponds (Kb, 1.8) and satisfactory correlate with the pond's depth (R2, 0.99) and hydraulic detention time (HDT) (R2, 0.73). On comparing coliform (TC and TTC) removal efficiency of different ponds in different seasons (viz; post monsoon, winter and summer), it was observed that total and thermotolerant coliform load increased in the post monsoon season. This was attributed to differences in the prevalence of infection and fecal excretion levels and due to the mixing of runaway water with raw sewage during the monsoon, which increased the bacterial load. Applying the dispersed flow model to assay coliform removal efficiency of WSPs system, we concluded that shallow ponds with a higher hydraulic detention time have good removal efficiency compared to deep ponds with lower hydraulic detention time.

This paper presents a consumption-based method accounting for greenhouse gas emissions at regional level based on a multi-region input-output model. The method is based on regional consumption and includes imports and exports of emissions, factual emission developments, green investments as well as low carbon development policies. We comparatively analyse three regional case studies in Denmark and show how regional initiatives implemented to reduce emissions are translated into easy to access input-output parameter changes and how the method transparently assesses the impact of various long-term regional climate plans on emissions. For the comparative analysis we further develop a carbon regional index (CRI), which delineates five key dimensions that define past, current and planned regional and embedded emissions. The method can form a basis for regional climate policies, promote the export of solutions from one region to another and enable policy-makers to observe good practices and test them at regional level before potential implementation on a larger scale.

Determination of safe and optimal routes for biomedical waste (BMW) collection and transportation using a fleet of vehicles is a complex issue. The issue gets significant, when the vehicles that outset from multiple depots, collects the BMW from hospitals scattered around a region and carry the waste to multiple disposal sites. The present paper deals with the development of a modified ACS-based approach to determine the optimal and safest route for BMW collection and transportation for such situation. The major objectives considered for route selection of vehicles, are the risk associated with the collection and transportation of BMW; total scheduling time of vehicles and number of vehicles. In this approach, clusters of the hospital nodes are constituted based on their distance from the nearest depot and late time window associated with the hospital node. Thereafter, the routes are scheduled and optimised using modified multi-objective ant colony system (MOACS). The computed results are validated abreast with benchmark solutions, demonstrating effectiveness of the proposed approach. Its applicability is elucidated using an illustrative example based on realistic data.
