The decision to formally acknowledge the role that architects have in causing climate change and alleviating it was made at a council meeting of the RIBA.
"The climate emergency is the biggest challenge facing our planet and our profession," said RIBA president Ben Derbyshire.
"But to have a significant impact we need to do more than make symbolic statements – we need to turn warm words into impactful actions."
Architects must "transform" their practice
The five year plan aims to make sustainable practices standard within the British architecture industry, improve government policy by lobbying and reduce the RIBA's own carbon footprint.
The RIBA also pledged to support the UK government's drive to make the country carbon neutral by 2050.
"We architects need to transform the way we practice and along with our fellow professionals around the world, make changes that will impact at a global level," added Derbyshire.

Climate justice movement Extinction Rebellion blockaded central London, prompting mass arrests, for ten days in April 2019. The UK parliament subsequently declared a climate emergency.
