Understanding the nuances of Green Premiums

Bill Gates’ book, “How to Avoid a Climate Disaster”, brings us closer to some inconvenient truths, the ones that tell us that achieving Net Zero comes with enormous costs.

Bill Gates’ book, “How to Avoid a Climate Disaster”, brings us closer to some inconvenient truths, the ones that tell us that achieving Net Zero comes with enormous costs. He starts by defining the concept of Green Premiums, the ones that differentiate a green product with a product that creates externalities. Gates defines Green Premiums as, “the difference in cost between a product that involves emitting carbon and an alternative that doesn’t?”

Taking his famous Green Premiums on Jet Fuels, the average retail price for a gallon of jet fuel in the United States over the past few years has been around $2.22, while advanced biofuels for jets cost around $5.35 per gallon. The Green Premium is the difference between the two, which is $3.13, or an increase of more than 140 percent.

Since airlines would not be willing to pay more than twice as much to fuel their planes—and many customers would balk at the resulting increase in air fares—the Green Premium on biofuels suggests that we need to find ways to either make them cheaper or make jet fuel more expensive. Or a combination of the two.

Or take his more famous example of the Electricity and the usefulness of the concept of Green Premiums, one study suggested that decarbonizing Europe’s power grid by 90 to 95 percent would cause rates to go up roughly 14 euros per month for a typical household in the European Union. In the United States, it would cost an extra $18 a month for the average home. While that is still a substantial premium, especially for low-income people, it’s encouraging that Europeans and Americans may be able to generate most of their electricity carbon-free for the cost of a few cups of coffee each month.

Once we know what’s driving a given Green Premium, it acts like a roadmap—it tells us the route we need to take to get to zero. In the case of electricity, one step is to keep deploying renewables where they make sense. Another is to invest more in developing technologies like long-term electricity storage, carbon capture, and advanced nuclear. And we need to modernize and expand the grids that deliver clean electricity from where it’s generated to where it’s needed—often a distance of thousands of miles.

But alas, Gates assumed that a decarbonizing the grid would be as simple as adding clean energy of Solar and Wind, etc., to the Grid, which would mean extremely unstable forms of energy generation would be added to create a semblance of stability that comes from the Grid. Obviously this would need making the Grid run on storage systems, only a minuscule of which is currently on the Grid and the costs of adding such storage systems would come at enormous costs. Surely his reference of $18 per household or Euro 14 per household have come of under-estimation of the enormity of tasks ahead.

Or take his more infamous example of the Cement. Consider the process of making cement. It’s responsible for releasing carbon dioxide in two ways: when fossil fuels are burned to generate heat for cement production, and during the chemical reactions involved in the manufacturing process.

We don’t yet know how to make cement without releasing this carbon. The best we can do is to capture it once it has been released and stash it away permanently, a process that adds between 75 percent and 140 percent to the cost of cement. Few construction firms would be up for absorbing such a price increase in any competitive market.

Green Premiums in manufacturing is tricky and this is noted by Bill and the book is replete with examples of innovations in various areas of manufacturing that attempts to progressively reduce the carbon footprint in the product creation. The journey of sustainability is actually many pronged, it does not need to replace only the high energy fossil fuel footprints alone that is used for production of the product in question; this is where Bill’s model is wrong.

Take Cement for example, if there was a way to replace all old concrete in buildings progressively to be recycled into concrete or to find replacement of concrete with more sustainable materials, the green premium calculations on Cement will be very different. Europe has already initiated recycled concrete from old buildings.

Aluminum holds a very striking example in Europe. In the late 1990s, Europe actually used 4 Million tons of primary Aluminum (that gets produced from bauxite ore in the earth’s crust needing 14 tons of CO2 emission per ton of Aluminum output) to produce value added products, now that is down to 1 million. The recycling of beverage cans, packaging, automotive and other applications have facilitated this shift.

The aluminum Green premium is actually negative, as there is always a spread available between an aluminum scrap and the primary metal over all the costs of conversion that allows recycled aluminum to prevail as a green resource. Thus recycling a product with a high carbon footprint allows a different route to the final output, one that may not create the same externalities, emissions et al.

Thus the focus on Net Zero must make allowance for these shifts in the manufacturing processes based on recycling as a crucial step. This is where the communities of people must converge to create solutions.

Holcim UK has released a report titled ‘Making Sustainable Construction a Reality,’ outlining its five-fold commitment to a greener future. The company aims to focus on decarbonisation, circular economy principles, smarter building methods, community engagement, and integrating nature. Based on a survey of 2,000 people, only 41 per cent felt urban spaces in the UK are sustainably built. A significant majority (82 per cent) advocated for more green spaces, 69 per cent called for government leadership in sustainability, and 54 per cent saw businesses as key players. Additionally, 80 per cent of respondents stressed the need for greater transparency from companies regarding their environmental practices.

The Global Cement and Concrete Association (GCCA) has launched the Low Carbon Ratings (LCR) system for cement and concrete, a new global rating based on products’ carbon footprints. The system uses a clear AA to G scale to help customers prioritise sustainability in material selection across construction sectors worldwide. The GCCA says that the LCR system is designed to be easily recognisable, with a simple visual graphic that indicates a product’s rating and provides consistency and comparability to other products.

FLSmidth has inaugurated a €21 million mill liner manufacturing plant in Casablanca, covering 11,250m² with a production capacity of 6,500 tonnes annually. The LEED-certified facility significantly reduces carbon emissions by up to 56 per cent and fully recycles water used in the manufacturing process. Up to 250 jobs will be created in the Valparaíso region. Mikko Keto, CEO, highlighted the plant as a symbol of FLSmidth’s commitment to sustainable mining and community engagement in South America. Earlier in 2024, the Denmark-based company announced plans to sell its cement division to sharpen its focus on mining operations.
