How Harvard is Going Fossil-Fuel Free

Jaclyn Olsen, Associate Director of Harvard’s Office for Sustainability, and Erin Craig, Vice President of 3 Degrees, a climate solutions firm hired by Harvard, discuss the University’s goal to be fossil-fuel neutral by 2026 and fossil-fuel free by 2050. Jaclyn and Erin discuss Harvard’s carbon footprint, its efforts to reduce emissions and realize health benefits, and its emerging strategy on carbon offsets.


Strengthening Carbon Offsets: The Oxford Offsetting Principles

Myles Allen, Professor of Geosystem Science at the University of Oxford and Director of the Oxford Net Zero initiative, discusses the controversy over carbon offsets and how the Oxford Offsetting Principles can help organizations reduce risk and improve transparency in their use of carbon offsets to support their net zero goals. Myles also talks about what the University of Oxford is doing to address its own emissions, and shares the advice he gives his students interested in embarking on climate change careers.

Playing With Fire: Russia, Ukraine And The Geopolitics Of Energy

The past several weeks have shaken the world order and given us a lot to process all at once. The IPCC released its latest report the same day the U.S. Supreme Court heard the most environmentally significant case in a decade, all while Russia’s invasion of Ukraine is dominating headlines and policy agendas.


Climate change is at a ‘political tipping point’ – Al Gore on the Radio Davos podcast

By Robin Pomeroy

Former US vice president Al Gore has been pushing for climate action for decades and maintains optimism, despite the fact that greenhouse gas emissions have continued to rise while the science says they need to be cut to zero by 2050.


Volts podcast: Rebecca Dell on decarbonizing heavy industry

By David Roberts

For most of the carbon-intensive sectors of the economy — electricity, transportation, buildings — we have a pretty good sense of how to eliminate carbon emissions. None of those sectors will be easy to decarbonize. Every one is an enormous practical challenge. But in each case, the basic path to zero is clear, and it mostly involves switching out fossil-fueled machines with machines that generate or run on clean electricity.


Could small nuclear reactors help protect the climate?

By YCC Team Photo: Idaho National Laboratory

As the U.S. transitions from fossil fuels, utilities must ramp up the amount of clean energy on the grid. Wind, solar, and nuclear power do not emit carbon pollution. But the amount of energy produced by wind and solar fluctuates, and large nuclear reactors are expensive and time-consuming to build.

Sustainable World Radio – Ecology and Permaculture Podcast

Sustainable World Radio’s motto is “Working With and Learning From Nature,” reflecting its focus on developing and discovering positive solutions to the challenges our environment faces. Founded on the principles of permaculture, episodes vary from those with a how-to approach (how to create compost, how to create a perennial garden) with interviews with permaculture experts. A companion podcast from Jill Cloutier, The Plant Report: Every Plant Has a Story, reflects the host’s exuberant love and abundant knowledge of plants from around the world, most of them familiar to most listeners but ripe for rediscovery.


A Sustainable Mind

A Sustainable Mind’s goal is to include the voices of women, young people, people of color, and others not regularly involved in conversations about sustainability. New episodes are sporadic and haven’t appeared since March 2021, but previous ones include interviews with an Australian surfer leading efforts to remove ocean plastic, with fellow podcaster Kamea Chayne of Green Dreamer, with a co-founder of zero-waste hair salons, and with a sustainability communications professional at the Marine Stewardship Council.
