Tyndall Talks is the Tyndall Centre's series of podcasts where we untangle the questions and discussions on climate science and climate policy.
La economía circular: Como se puede aplicar en el ámbito de América del Sur
Este es el primer episodio del podcast en español y vamos a conversar sobre que es la economía circular, como se puede aplicar en el ámbito de América del Sur y como puede influir en la lucha contra el cambio climático
Nuestros invitados en este episodio son Edmundo Munoz y Nicolas Labra, ambos expertos en economía circular. Dr Edmundo Muñoz es Ingeniero Ambiental y Doctor en Ingeniería de la Universidad de La Frontera, Temuco, Chile. Actualmente es profesor asociado e investigador de la Universidad Andrés Bello en Santiago de Chile. Su línea de investigación principal es en análisis del ciclo de vida, metodología que ha utilizado para evaluar estrategias de mitigación de impactos ambientales de actividades antrópicas con especial énfasis en cambio climático. Nicolás Labra es un investigador en temas de economía circular y gestión de residuos con foco en el sector informal del Sur Global. En el contexto de su doctorado en el Centro Tyndall Manchester, está investigando la forma en que el sector informal o recicladores de base gestionan los residuos electrónicos y evaluando alternativas para su integración en base al análisis ambiental y social de ciclo de vida.
What is a circular economy?
Our episode is about circular economy and renewable energy. According to the Circularity Gap Report of 2019, an annual report produced for the yearly World Economic Forum in Davos, “The world can maximise chances of avoiding dangerous climate change by moving to a circular economy, thereby allowing societies to meet the goals of the Paris Agreement on Climate Action.” The role of circular economy in achieving net zero has been acknowledged by many countries. The World Resources Institute notes that one-third of nationally determined contributions – climate action plans by each country to cut emissions and adapt to climate impacts – updated and submitted in 2021, largely across Europe and some other G20 countries, include mention of a circular economy. But what is a circular economy and how can it help as a solution to climate change? What role does renewable energy play in a circular economy?
Our guests for this episode are Christopher, Velma, and Jingyi – PhD students at Tyndall Manchester whose research focuses on renewable energy and circular economy.
Beyond private jets and cruise ships: The problem with aviation and shipping emissions
Our episode today is about aviation and shipping emissions. Aviation emissions have become a hot topic recently, thanks to the revelation that celebrities like Kylie Jenner and Taylor Swift have been using their private jets even for short trips – apparently as short as a three minute flight! This has caused some uproar, especially as climate researchers and activists have been pushing for a reduction of emissions in the aviation sector. Over the years, with cheaper tickets available to the public for air travel, aviation emissions have skyrocketed. According to data from Oxford University, flying accounts for 2.5% of the world’s emissions. The UK Research Institute released a study that shows aviation could consume ⅙ of the remaining temperature budget to limit warming to 1.5C. Similarly, the shipping industry is responsible for around 940 million tonnes of CO2 annually, which is at least 2.5% of the world’s total CO2 emissions. Why is aviation and shipping problematic and what solutions can we implement to solve this problem?
Our guest are James and Asha, post-doc researchers at the University of Manchester whose research focus is on aviation and shipping.
Greenhouse Gas Removal: What is it and can we really do it?
This episode is about the real world feasibility and consequences of two greenhouse gas removal approaches: first, large-scale afforestation, and second, biomass energy with carbon capture and storage (BECCS). They both play the largest roles of any greenhouse gas removal approaches in future low emission scenarios that keep global mean temperature increase to below 1.5 °C and 2 °C.
We have three guests for this episode Nem Vaughan, Clair Gough and Diarmaid Clery from the FAB-GGR team or the Feasibility of Afforestation and Biomass Energy with Carbon Capture and Storage for Greenhouse Gas Removal.
Clair is senior research fellow at the University of Manchester where she has worked for many years on carbon capture storage, looking at everything from the social and political aspects to its role in decarbonising industry and removing carbon dioxide.
Diarmaid is a research associate at the University of Manchester, and previously worked at the University of East Anglia. His background is in engineering, working on technical aspects of biomass energy with carbon capture and storage (BECCS), but now working on more social aspects of greenhouse gas removal, and industrial decarbonisation.
Nem is an associate professor at the University of East Anglia where she works on greenhouse gas removal methods, from an earth system perspective through to public and policy.
Why Tracking Adaptation is Important
Adapting to climate change means taking action to prepare for and adjust to current and predicted effects of climate change. Adaptation plays an important role in managing past, present and future climate risk and impacts. However, there is an ‘adaptation gap’ where the distance between existing adaptation efforts versus adaptation needs is widening. Tracking national adaptation plans is deemed critical to support future decision-making and drive future actions.
Our guest today is Katie Jenkins. Katie has created an Adaptation Inventory of adaptation actions happening based on official records of adaptation projects being implemented by both public and private sector here in the UK.
Energy justice amidst increasing energy prices in the UK
Our episode this month is about energy justice. The energy price crisis in the UK and beyond, means many more households will find themselves in fuel poverty - meaning they find it unaffordable to heat their homes to a safe and healthy level. In 2019, 3.5 million households in the UK were considered fuel poor and this is likely to have increased significantly as a result of the pandemic and energy crisis. How do we address this from a justice perspective? Our guests for this episode is Sarah Becker and Prof. Aimee Ambrose.
