Sophie Tipper, passionate about environmental policy since middle school, joined the Colorado Youth Advisory Council (COYAC) in July 2023. Noticing youth were absent from state environmental task forces, she and Ashna Shah developed a policy memo recommending youth advisors for the Colorado Department of Public Health's Environmental Justice Board. This led to drafting SB25-055, a bill requiring two youth members on the board. Despite a sponsor's election defeat, Tipper secured new support, and the bill was introduced to the Colorado legislature in January 2025.

SB25-055 subsequently passed and was signed into law by Governor Jared Polis in May. Tipper, now drafting a plastic pollution bill, believes youth advocacy empowers young people to drive real policy change. She hopes to inspire similar youth-led environmental initiatives nationwide.

Political and economic shocks present opportunities for market transformation. In this episode, Jonquil Hackenberg (Ellen MacArthur Foundation) and Lindsay Hooper (Cambridge Institute for Sustainability Leadership) discuss how businesses can collaborate to drive system-wide change.

They explore catalysing market interventions, designing out competitive disadvantages, and building pre-competitive coalitions. Harnessing business and private sector power is crucial for real transformation towards a circular economy, which eliminates waste and regenerates nature.

To build a competitive and resilient future, the fashion industry must embrace circular business models. A new film from The Fashion ReModel, an Ellen MacArthur Foundation project, highlights real-world examples from Arc’teryx, H&M Group, and Tapestry (Coach), demonstrating how to make money without making more clothes.

These models—including rental, resale, repair, and remaking—offer economic resilience by reducing exposure to supply chain disruptions and price volatility. Businesses can embed these strategies into their core operations. The Ellen MacArthur Foundation, an international charity promoting a circular economy, encourages action.

The global food system generates 20-30% of greenhouse gas emissions, largely from production. Conventional rice production, a staple for over half the world, alone generates emissions equivalent to global aviation. The System of Rice Intensification (SRI) offers an agroecological solution.

SRI employs simple interventions to significantly reduce water use, methane, and chemicals, while boosting yields and cutting labor. Currently 4% of rice production, scaling SRI to 25% could reduce emissions equivalent to India's total output.

The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for climate change assessment. Established in 1988 by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO), its mission is to provide a clear scientific view on climate change and its potential environmental and socio-economic impacts. The UN General Assembly endorsed its formation.

The IPCC's Fifth Assessment Report, "Climate Change 2014: Impacts, Adaptation, and Vulnerability," was published on March 31, 2014.
