 AESOP – An Ethical and Social Responsibility Portfolio

With a grant from the Engineering and Physical Sciences Research Council APRES has developed an industry-academia joint venture called AESOP, which stands for An Ethical and Social responsibility Portfolio for construction professionals.

AESOP broadens the focus of responsible sourcing to include people and labour-related issues, including employment and payment practices in the UK and overseas. An article on stamping out slavery here illustrates the sort of issues being addressed.

The AESOP programme runs a series of events and conferences, in addition to publishing the UK Manifesto for Ethical Sourcing in Construction and an Ethical Design Guide, aimed at contractors, specifiers and designers – see details on both below.

UK Manifesto for Ethical Sourcing in Construction

The UK Manifesto for Ethical Sourcing in Construction, created in an industry application of a “hackathon”, was published in 2015.

The manifesto broadens the industry’s area of accountability beyond responsible sourcing and procurement, which deals mainly with environmental and sustainability issues, into the fair and ethical treatment of labour and sub-contractors. Its 35 co-authors include clients, contractors, designers, manufacturers, suppliers and industry organisations.

Derived from the world of Silicon Valley software development, the “hackathon” model was adapted by APRES for this purpose (an article, ‘Industry urged to build ethically’, gives more details). The manifesto marks the start of a long-term campaign to align industry values with those of corporates and activist communities worldwide.

Ethical Sourcing: A Designer’s Guide

The guide offers a broad community of practitioners from architectural and engineering disciplines, the opportunity to appreciate the wide-ranging challenges and possible trade-offs with ethical sourcing. The Guide does not seek to provide a utopian answer to the pitfalls of supply chain risks, but rather to present the very real challenges in a more accessible manner in order to inform and steer design choices and specifications.
