  • Fresh insight on the War on the Planet

    Track changes provides fresh voices on and ways of seeing. I have been listening to the discourse for decades almost till I’m despairing and immune to the horror of fossil fuel war on our planet and us. But the people speaking here offer knowledgeable, rational understanding in language that speaks directly to everyone.

Talking Points

Recent interactions between the hosts and their guests.

The climate change dejargonator: With Mark Tilly
Q: Who buys carbon credits and difference between voluntary and compliance markets?
Buyers range from energy companies to governments and institutions; voluntary markets are driven by targets and sustainability goals, while compliance markets are mandated by law to meet emissions targets, with prices influenced by supply, demand, and policy signals.
The climate change dejargonator: With Mark Tilly
Q: What are carbon credits and are they the same as carbon offsets?
A carbon credit represents one tonne of CO2e avoided or removed and can be used for offsetting, but credits have broader uses beyond offsets depending on the system; offsets describe the action of compensating emissions rather than the credit itself.
The climate change dejargonator: With Mark Tilly
Q: What is a carbon market?
A carbon market is a marketplace where carbon credits or allowances are bought and sold, but unlike physical commodities, these assets represent emissions reductions or rights rather than tangible goods.
President José Ramos-Horta: Development in a time of climate change and disruption
Q: Could you tell me about Timor-Leste's goals for the Bayu-Undan gas field and the Greater Sunrise gas field, and how they fit with development and climate commitments?
Greater Sunrise is seen as a relatively cleaner non-renewable energy source that supports national security and people's well-being; while non-renewable, it is essential to finance development in the near term, with a commitment to protect oceans and pursue a broader transition aided by international partnerships and eventual revenue for sustainable investments.
Cheaper, cleaner energy and net zero: The Productivity Commission view
Q: What are the most central recommendations for keeping costs low while speeding the transition?
The podcast highlights early signaling and consistency in policy actions, prioritizing energy market reforms (especially the NEM) and streamlined environmental approvals, while leveraging cost-effective technologies and maintaining a focus on least-cost options and broad societal benefits.
