I am happy to tell David Nixon (News Analysis July 17) that the RIBA has been anything but waiting for the government to tell it what to do on climate change: the opposite in fact, with some impact

However, at a time when there are sometimes several conferences in the same week on this subject, rather than hold another we shall push on with our four-part climate change strategy adopted in 2006: we’ll campaign for an effective international treaty; exchange information with members, clients, co-consultants and schools of architecture; improve our own corporate carbon footprint, and stage widely-admired lectures.

The International Dialogues: Architecture and Climate Change series of lectures and events was launched in early 2007 by Nobel Laureate Wangari Maathai, who has since been followed by many distinguished contributors including David King and Nicholas Stern.

The programme exists as a forum to engage the architecture and construction industries with leading environmental thinkers and activists to enable discussion and action on issues including globalisation, energy sustainability and international development.

Ruth Reed has invited me, and I have enthusiastically agreed, to continue to lead the RIBA’s Combating Climate Change programme in my year as immediate past president.
