CLIMATE investor forum
Driven by the demand for companies and countries to decarbonise and meet net zero goals, a whole new global climate solutions industry is rapidly evolving. The mission of the Climate Investor Forum, founded by Peter Castellas, CEO, Climate Zeitgiest - is to catalyse and facilitate investment in business solutions that address climate change. Now in strategic partnership, Climate Zeitgeist and Quest Events, are united in this shared mission.
With Quest Event's proven track record delivering over a dozen leading sustainability and energy forums, and Climate Zeitgeist’s deep strategic investment networks, our joint venture offers a powerful and complementary platform to catalyse climate action and drive meaningful outcomes for all stakeholders.
Climate Zeitgeist is at the forefront of this global movement. We work in collaboration with investors, funds, financiers and companies with decarbonisation solutions looking to scale and corporates seeking to integrate technologies, products and services to deliver their net zero strategies.
