Advancing Knowledge in Environmental Sustainability
Singapore Environment Institute (SEI) is the training and knowledge division of the National Environment Agency (NEA). Within NEA, SEI distils and documents the knowledge residing with experienced staff, as well as knowledge from other relevant sources, for transfer to the next generation of officers via its training programmes. The Institute also develops and up-skills the local industry’s manpower capabilities, thereby adding value to Singapore’s environmental arena. SEI’s public lectures feature renowned environmental speakers who catalyse thought leadership and foster communities of best practices. SEI’s collaborations with, and strong support from industry, academic and government organisations, are instrumental to its goal of ‘Advancing Knowledge in Environmental Sustainability’.

EnvisionIssue8ENVISION Issue 8: Creating Sustainable City Life, from Blueprint to Reality
ENVISION Issue 8 looks at creating sustainable city life, from blueprint to reality. In particular, it features the Sustainable Singapore Blueprint 2015 (SSB), which maps out a national vision for Singapore to become a liveable and endearing home, a vibrant and sustainable city, and an active and gracious community. Working in partnership with our stakeholders, NEA plays a key role in Singapore’s efforts to realise our SSB vision, for instance, through  pollution control measures to improve Singapore’s air quality, encouraging the practice of the 3Rs of reduce, reuse and recycle, and in public engagement to foster community ownership of the environment. This issue also highlights international trends for a more sustainable way of doing business, and explores technological innovations in waste management, resource reclamation, carbon capture and alternative energy. Beyond policy and technology, Issue 8 delves into the cultural factors that influence environmental behaviour. Different perspectives are explored, such as the engagement of our youths and the inculcation of environmental values among our citizenry, as these bottom-up activations would make an enormous difference to our environmental outcomes in the years ahead.

Envision7ENVISION Issue 7: Threats and Opportunities
This issue explores the many environmental threats and opportunities we face in everyday life and business. One such environmental threat in our urban setting is of course dengue, for which there are a variety of community efforts and scientific initiatives underway to help curb the spread of this disease. Our activities are also shaped and impacted by natural phenomena, from daily weather to long term climate shifts. Besides potential threats, we explore the many opportunities for government and businesses to embrace environmentally-friendly activities. For example, various approaches to recycling food waste, industrial and electronic materials are all worth a closer look. Issue 7 also examines how a move towards a more resource-conscious economy can be of benefit to industry.

Issue6sENVISION Issue 6: Strengthening the Green Economy
Recent years have seen interconnected environmental and economic predicaments shift the discourse on growth and its implications. Concepts like green economy have emerged and received political and business traction. But how much of these are merely green visions versus reality? ENVISION Issue 6 features many case studies of technology, best practices, systems, and policies that are taking shape in this avenue. Renewable energy technologies are gaining ground, and governments and businesses are transforming their value chains and cutting energy consumption. Singapore too, is making inroads in areas like energy efficiency and green buildings. There is increasing interest in the so-called ‘circular economy’ which aims to loop in linear industries that currently wreak environmental destruction through their externalities. On a planet with seven billion people, major transformations are not an overnight affair. However, the developments we see in ENVISION Issue 6, alongside many others globally, may signal paradigm shifts in the ways our economies work. As Dr Martin Shaw put it, “A lot of opportunity is going to arrive in the next 20 years disguised as loss.” Whether it is through a green economy or something entirely new that emerges from such beginnings, those who are prepared will prosper.

With growing environmental threats and challenges to major global cities, governments and communities are increasingly working together to help find solutions. One aspect of this involves tapping the expertise of the “crowd” to spur unconventional, rapid and innovative solutions.  With governments and industry allowing public access to environmental data and involving them in consultative design processes, the opportunity for synergy emerges.  Practitioners of all backgrounds are increasingly empowered by leveraging phenomena such as big data, new sensing and analytics systems, as well as technology applications.  The fifth issue of ENVISION includes features on environmental data analytics, the latest technology, new tools being developed for industry and within government, how crowdsourcing is helping to change environmental outcomes, a guide to environmental apps, as well as inspiring environmental case studies from Singapore and beyond.
