To celebrate Earth Day we’ve compiled a list of architects and designers… who are doing pioneering work, ranging from exploring timber construction to designers thinking radically about circularity and scientists developing new low-carbon materials:

Andrew Waugh, co-founder of Waugh Thistleton Architects – a vocal advocate for building more sustainably and an outspoken critic of existing UK regulations relating to environmental construction. As part of his role in the Architects Declare pressure group, Waugh co-authored a recent report setting out ways to reduce carbon emissions associated with the built environment.

Marco Vermeulen, founder of Studio Marco Vermeulen – a Dutch architect and founder of his namesake design office Studio Marco Vermeulen. Vermeulen is known for his use of timber and raw materials to create sustainable buildings as well as his research into sustainable forestry and how it can be used to form a circular approach to construction.

Michael Green, founder of Michael Green Architecture – a Canadian architect at the forefront of mass timber innovation in North America and the world. He has authored two books on the subject and delivered a TED Talk titled “Why we should build wooden skyscrapers”.
