My research project
A framework for Measurement and Management of Corporate SustainabilityThe aim of this research is to measure corporate sustainability performance and management, with related themes of Corporate Social Responsibility (CSR), employee engagement and the net zero transition. The project has two phases. Phase one assesses and compares sustainability performance of companies in a developed economy (the UK) and in a developing economy (Sri Lanka) using a holistic new sustainability framework developed and tested through this research. This includes four case studies of companies in the tea sector with deep insights into sustainability strategy and management, CSR and employee engagement. Phase two includes the measurement of sustainability in 40 companies of varying sizes, from various industry sectors to further demonstrate the use of the framework in SMEs and listed companies.
The 7E model developed for sustainability performance measurement, considers economic, environmental and social impacts which includes seven pillars of measurement. The study applies this model to measure economic sustainability, emissions and materials management , energy consumption, waste, circular economy approaches, social impacts and governance. The outputs include a practical framework that can assess the impact of production activities, improve knowledge of sustainability towards making potential savings, benchmark and share best practice for implementing sustainability into profitable product strategy, comparison of CSR approaches and actions towards decarbonisation.
Participating companies are provided with insights and analysis to support their sustainability planning and business strategy.
The findings have been presented at international conferences and in two publications, with a third publication in progress.

Research projects
A UKERC Whole Systems Networking Fund (WSNF) project. Energy modelling plays a vital role in the transition to a net zero economy and contributes to energy security, with models underpinning decision-making across policy, industry and civil society.
The energy sector remains one of the least gender diverse and women are significantly underrepresented in the energy modelling research area. This project built a network with multiple resources to encourage persons from different disciplines and sectors to join energy modelling research and practice.
The project will bring together academic researchers, companies along the energy supply chain, policymakers in both central and local government, NGOs and practitioners.
The outputs include:
- An online Energy Modelling Network with international members, to build connections for future discussions among the peer community.
- An online platform with open learning resources (e.g. reports, publications, presentations) on multiple energy models and fundamental training.
- Workshops with bespoke mentorship from professional energy modelling practitioners and a long-term mentorship scheme beyond the lifetime of this project.
Two workshops have been completed and resources shared with the Network. Further engagements are planned with the network community.
The Sustainable Business Project is a PhD at the Centre for Environment & Sustainability, University of Surrey led by Nayanee Silva, supervised by Dr Walter Wehrmeyer and Professor Richard Murphy.
Phase 1 of the study has been completed with four detailed case studies of business sustainability which demonstrate a new 7-part sustainability framework (7E Model). Phase 1 results have been presented at two international conferences.
Phase 2 is currently underway. This will include a range of companies from various industry sectors in the UK and Asia. SMEs and large, listed companies are included using surveyed data and secondary data.
Participating organisations will receive a benchmark score of their sustainability performance using the new 7E Model framework developed for this project.
The Employee Engagement survey assesses attitudes to work, community engagement and wellbeing. The results of this survey provide insights into employee behaviour using statistical analysis to help understand employee attitudes and characteristics which are unique to each organisation.

Managing organisational sustainability is complex, with multiple aspects including decarbonisation, sustainable finance, management of material flows and waste, to reduce harmful impacts and integrate sustainable approaches into business strategy. To improve sustainability, organisations must measure and manage the impacts of operations on the environment and society. This empirical study featuring case studies in the UK and Sri Lanka, examines the economic, environmental and social activities of company operations in the tea sector to evaluate and compare sustainability performance. The Triple Bottom Line (TBL) approach is expanded through a holistic sustainability framework proposed in this study, to support organisational sustainability measurement. We propose a ‘7E’ sustainability model that measures activities across seven operational areas of the organisation to create an overall sustainability score for benchmarking that aids sustainability improvements with an interconnected approach. The model supports organisations to identify savings, explore greener materials and energy choices through detailed insights and allows for ranking and comparison of companies using a sustainability index. A mixed methods approach is used to provide an analysis that offers granularity and comparability for sustainability strategy. Best practices from case studies, insights arising from the analysis of company surveys, interviews and employee surveys provide useful information on sustainability performance and decarbonisation progress. This research demonstrates the use of the 7E model as a practical tool for managers and organisations to improve sustainability management.
Managing corporate sustainability involves consideration of the economic, environmentaland social impacts of business activities on communities and society. Successful corporatesustainability strategy and sustainable operations must include an engaged and commit-ted workforce. It has been seen that employees are increasingly seeking more purpose atwork, with an awareness of environmental and social issues. Research has shown thatemployees engaged in corporate sustainability practices perceive their work as meaning-ful contributions to business performance. This empirical study explored sustainabilityperformance in the tea industry, measured with a holistic sustainability framework andinvestigated the linkages between corporate social responsibility (CSR), employee engage-ment, and corporate contributions towards sustainability. The operations of participatingorganisations measured via a ‘7E’ model to benchmark sustainability performance, werecompared with how employee engagement is influenced by CSR and wellbeing aspects.Data was collected from company sustainability surveys and surveys of 1146 employeesin the tea industry. The results were analysed using a cluster model to assess employeeattitudes to CSR and corporate sustainability practices towards sustainable development.The findings show that companies with strong company sustainability performance anddeveloped social sustainability with CSR activities, have employees with higher partici-pation at work and outreach engagement. Dimension reduction and the two-step clustermethod was used to classify employee responses, showing the most engaged employeesexhibited ‘shared values’ characteristics aligned with corporate engagement and socialoutreach. These results contribute to research on sustainability management from corpo-rate and employee perspectives, with insights for sustainable development through CSRand sustainable business operations.
