The year 2024 will be a critical one for accelerating our progress towards a net-zero future. It’s crucial now that we sustain momentum, galvanise concerted action, and ensure the upholding of commitments and accountability of governments and leaders to deliver against key climate pacts.

Staying tuned to the big events and conferences taking place across the year in the realm of climate and sustainability, helps us keep abreast of news and global progress in the net zero transition, on both a business and individual level.

In 2024, there’s a plethora of UN summits, including the Biodiversity COP16, Climate COP29, the 6th UN Environment Assembly, the 12th World Urban Forum, and the UN Summit of the Future, to name a few.

Further to these, several energy conferences and expos are scheduled throughout the year; as well as youth climate activist events, and smaller-scale summits for business leaders and industry experts to showcase schemes and innovations for addressing challenges within our densely populated urban areas.
