Hosted by the Ellen MacArthur Foundation and WRAP, the Circularity & Zero Waste Stage will convene policymakers, practitioners, investors and innovators to showcase circular models and sustainable waste management practices already moving from principle to implementation.
The expanded programme of partner events and roundtables will dive deep into key opportunities of the transition.
Hosted by Climate Action and the London Climate Action Week Secretariat, this exclusive evening convenes 350 UK and international climate leaders to celebrate the 8th edition of London Climate Action Week and the UK’s global leadership on climate, with a curated programme of speakers and cultural performances.
The solutions already exist. We must tune out those who seek to gain from our continued inaction and mobilise the positive driving forces in the UK, across Europe, and around the world.
Returning for its 8th year at London Climate Action Week, the Climate Innovation Forum convened a curated audience of over 3,250 of the world’s most influential leaders from government, business, policy and finance, to connect, collaborate, and accelerate climate action and implementation.
The day featured a range of panels covering digitalisation, nature financing, and the global momentum at the midpoint between COPs, culminating in an inspirational talk from Former US Vice President and Nobel Prize Laureate Al Gore. The main policy theme that surfaced throughout the event was the shift from negotiation to implementation.
