The Principles for Responsible Investment Initiative (PRI) has appointed the agency to provide strategic comms advice following a six-way pitch process.
PRI aims to foster the development of a more sustainable global financial system by highlighting the relevance of ESG (environmental, social and corporate governance) factors for the world's asset managers and pension funds, as well as encouraging the adoption of these issues into investment decisions.
Since PRI's creation less than seven years ago, more than 1,000 investment bodies managing around US$30 trillion have become signatories to PRI's six principles.
Lansons will report to head of comms Matthew McAdam to advise PRI on a global basis. The brief includes supporting PRI's participation in the Rio+20 conference on sustainable development next month.
The Lansons team is led by chief executive Tony Langham and associate director Charlotte Collins-White.
The principles were devised by the global investment community in 2005 after the then UN Secretary-General Kofi Annan invited a group of the world's largest institutional investors to help develop new standards.
