Sustainable transport advocate Kirsten Corson tells Ross Inglis that the war on Iran both exposes our dependence on imported oils and offers an opportunity to move away from them.

Wondering how well we are doing with cutting emissions? London-based climate communicator John Lang runs the ruler over NZ's performance and offers Ross Inglis a take on the maturity of the climate debate here, why institutions matter more when governments duck their climate responsibilities, and quick answers to three top climate whataboutisms.

The outgoing chair of major NZ insurer Tower says climate change is costing lives and money but there are bigger fish to fry before we cut emissions. Ross Inglis asks him to explain.

 What does October's energy policy announcement mean for the future of NZ's electricity market and the climate? Law professor Barry Barton steps Ross Inglis through a package big on fossil fuels and very quiet about renewables. 

Earlier this year New Zealand's first and largest big storage battery began selling into the grid; there are signs that it is already softening prices. So, are we on the cusp of a low-emissions electricity transformation? Climate and energy modeller Dr Jen Purdie tells Ross Inglis that we are...to a point.

Every year the fashion industry produces over 24 billion shoes made largely of synthetics, with little regard for the materials sourced, the wellbeing of the people involved or impact after disposal. Orba shoes are different. Designed in NZ, made from entirely natural materials every part of every shoe Orba makes for the next 100 years will be gone before any synthetic sneakers discarded yesterday. Orba is also included in this year’s Next List - the definitive list of the most sustainable products and businesses as judged by the Sustainable Business Network. Vincent was joined by Gillian Boucher, sustainability manager, and Scott Anderson operations manager. https://orbashoes.eco/

Auckland builder Paul Webster-Young is turning a new home for his sister into a case study for construction that sends less waste to landfill and costs less over time. The key, he tells Ross Inglis, is careful selection of materials and a new kind of collaboration with architects.

New Zealand's houses have come a long way since the '70s but there's plenty we can do to make them more sustainable. Auckland architect Mike Hartley is designing for less building waste and that, he tells Ross Inglis, starts by talking with the builder.

The annual Climate Change and Business Conference is the biggest corporate meet-up on the climate agenda, attracting delegates from industry, politics and NGOs as well as overseas high-noters. This year’s event featured Lord Adair Turner, of UK Energy Transmissions Commission, Wang Xiaolong, the China ambassador to NZ and Cynthia Houniuhi, who led an historic delegation of Pacific youth to the International Court of Justice (ICJ) this year. Alec Tang of KPMG and Joanna Silver of Westpac were both at the conference and joined Vincent to discuss their reactions.

What would a journalist from outside New Zealand find if they ran the ruler over our current climate policies? Australian writer Royce Kurmelovs has done just that, and he tells Ross Inglis that the answer can be rendered in two words: quiet quitting.

Why is it so hard to invest in nature - not for extraction but for nature itself? We invest in human health. Why don’t we invest in nature health? Well, increasingly we are trying. Nature Based Solutions are embedded in our National Emissions Reduction Plan and in the Climate Adaption Plan - but adoption and action are slow. Just ask anyone trying raise money for conservation, predator control or green infrastructure. Investing in nature is not happening fast enough or at scale. Robin Mitchell is the founder of advisory firm Nature Positive. He is an international biodiversity management expert who advises governments, corporates and finance industry on nature climate strategies.

If you reckon our national strategy for reducing emissions is short on ambition, Jessica Palairet agrees. Jessica heads Lawyers for Climate Action which, together with the Environmental Law Initiative, is taking the government to the High Court for a judicial review of the plan. She tells Ross Inglis what's wrong with the plan and how the law can help fix it.
