How Can Carbon Markets Limit Climate Change?
Description
Carbon markets are advancing on a global level, following the first country-to-country trades at COP27. The Energy Podcast investigates how carbon pricing works and examines what role it can play in the race to reduce greenhouse gas emissions.
Presented by Julia Streets. Featuring Dr Hasan Muslemani from the Oxford Institute of Energy Studies, Andrea Bonzanni from the International Emissions Trading Association and Shell’s senior carbon pricing policy advisor, Dr Malek Al-Chalabi. With additional contribution by Stephen Kansuk, Head of Environment and Climate Change at the United Nations in Ghana.
The Energy Podcast is a Fresh Air Production for Shell, produced by Annie Day and Sarah Moore, and edited by Molly Lynch and Sophie Curtis.

Andrea Bonzanni: Emissions must be reduced globally irrespective of where they take place. The atmosphere is one at the end of the day. Article VI allows reducing emissions where it’s more efficient.
Dr Hasan Muslemani: We have solutions that are being praised as the holy grail of net- zero… The issue is that we need all the solutions that we can get because in the fight against climate change, we are really in a race against time.
Julia Streets: The cost of climate change. It's a phrase commonly used by governments, companies, and campaigners across the world when discussing the need to limit global warming to well below two degrees Celsius. Quantifying the exact cost of far- reaching effects of climate change is not an easy task. But putting a price on emissions is viewed by many as an effective means to help drive down levels of CO2 in the atmosphere. The idea is simple. Putting a price on carbon emissions creates a financial incentive to reduce them.
Carbon markets have existed for decades. There are many carbon pricing systems around the world, but at present, it is estimated that only a quarter of emissions are priced. That could soon change. At last year's COP27 climate conference in Egypt, the first country- to- country carbon trades took place. Could this pave the way for further uptake of carbon trading and what impact could that have in the fight against global warming?
Hello, I'm Julia Streets, and today on The Energy Podcast: How can carbon markets limit climate change?
MUSIC ENDS
With me to discuss this are Andrea Bonzanni, who's the international policy director at the International Emissions Trading Association, who you may well remember from a previous episode of The Energy Podcast. He is joined by Dr. Hasan Muslemani, who is the head of Carbon Management Research at the Oxford Institute for Energy Studies. And our third guest is Dr. Malek Al- Chalabi, who is a senior carbon pricing policy advisor at Shell.
Hasan, perhaps I could start with you. For the benefit of the audience, would you just mind explaining what we mean when we talk about carbon markets?
02:18
Dr. Hasan Muslemani: The fundamental concept behind a carbon market is really to put a price on carbon, or in other words, to quantify the cost of damages that emissions will cost our society over time. To do this, we have, at the heart of carbon markets, what is called carbon accounting or greenhouse gas accounting. This represents a set of standards and methods that help us quantify but also verify the impact that each business creates on the environment, and this impact is reported in terms of tons of CO2 emitted.
Now, something that I really want to emphasize here is that today, we speak of carbon markets, but we need to differentiate between two different types of markets. The first is what we call a compliance market, which is a market that is heavily regulated and corresponds to a specific region or jurisdiction, and where companies within that jurisdiction have to take part in the market. The other one is a voluntary one. This is a lot less regulated and where participation is voluntary, as the name implies. The voluntary carbon market is based on the concept of offsetting. That is where a company wishes to mitigate or neutralize its own emissions. So, it goes out and invests in projects which are reducing equivalent amounts of emissions elsewhere in the world.

Julia Streets: Can you talk to us a little bit about how they work in practice in everyday terms?
03:36
Dr. Hasan Muslemani: Starting on the compliance markets, and the objective is really to put a price on carbon, there's two different ways to do this. The first one is carbon taxation, which should be a simple concept. We have countries like Norway and Denmark, which would impose a specific tax on every ton of CO2 that a company would produce within those countries. The key here, really, is for that carbon tax to be high enough to incentivize businesses to change behavior or to move to greener production. This is essentially a stick form of regulation where businesses have to lower their emissions or face an additional cost.
The other mechanism, which is a cap and trade mechanism, which is the more familiar one, and in this system we have an authority, say, the European Commission, which sets a cap on how much emissions can be generated as a whole within the continent, within Europe, and then allocates a number of allowances or carbon credits to European countries and companies for them to trade amongst each other. Here, each carbon credit or allowance is representative of one ton of CO2.
This allocation process, what I want to note, is done using the historical emissions of each one of these companies. This is a process that we call grandfathering. The overall cap is reduced each year in order to meet a certain European climate target in the future. The way this works is where companies that have lowered their emissions below their targets, now they have surplus of allowances, which they can go into the market and sell to companies that did not do so well and will require to buy credits. So, this mechanism really is sort of a carrot but also a stick sort of regulation.

Julia Streets: Thank you for explaining how they work. I suppose my next question, is how effective are they proving to be?
05:19
Dr. Hasan Muslemani: The longest running and actually the biggest ETS in the world, that is the EU ETS or emission trading scheme. This has started in 2008 and has gone through different phases over the years. But I do want to mention that it has suffered from a number of setbacks over those years. To give an overview, the carbon price at the beginning was around 30 euros per ton, but that price has crashed to less than 5 euros around the financial crisis of '09. This was most likely because of two main reasons. The first one is that companies had to report their emissions in such a regulated manner that they have not done before, and so they might have overestimated how much emissions they emit and hence how much allowances they eventually received from the system. But also, because of the financial crisis itself, it meant that business offices aren't lit, emissions aren't as high as usual, so they did not need to surrender as much allowances at the end of the compliance phase, which eventually meant there's an oversupply of credits in the market, and so the price has crashed.
The good news is the EU ETS has gone through sort of a recovery mode over the past 10 years, and today the price has not only recovered but reached the level which is believed to incentivize most sectors to lower emissions, and that level is around 100 euros per ton.

Julia Streets: It's been so helpful to get a sense of progress, thinking about the dynamics of the market since launch, and also to think about the market share.
Andrea, let me bring you in here because this is about the world's attempts to limit global warming to well below two degrees Celsius, in line with the Paris Agreement. Are we likely to see the growth of carbon markets in pursuit of this great ambition?
07:03
Andrea Bonzanni: Well, we know that meeting the goals of the Paris Agreement requires a radical transformation of many areas of our economies and our lives, and for the reason outlined by Hasan, carbon markets and carbon pricing in general are one of the tools that governments are increasingly considering. Carbon markets are spreading from a core of rich runs economies such as the EU, California, South Korea, and New Zealand, to middle- income and emerging countries. This year, we had Mexico and Indonesia launching their emission trading systems, and the two schemes are expected to expa
