The Carbon Footprint Of Meat

By | | No Comments

Most people know and accept that meat has a huge carbon footprint.

The land required to harvest red meat is 28 times more than that of pork or chicken. Red meat also needs 10 times the amount of water, and results in more climate-warming emissions by a factor of 5. It’s also worth noting for context that over 90% of our water footprint is created by food production.

Are you a heavy meat eater, or a vegan? This graph courtesy of Vox breaks it down:

less meat less emissions

This recent article from Climate Progress collates multiple sources to illustrate the problem, and this image shows the carbon footprint of one hamburger.

Carbon footprint of one hamburger

“Research published in the journal Proceedings of the National Academy of Sciences has found that livestock emissions are on the rise and that beef cattle are responsible for far more GHGs than other animals, including chicken and pork.

Meat production’s heavy environmental toll is not new, but the scale is surprising: The study found that beef requires 28 times more land to produce than pork or chicken, 11 times more water, and results in five times more GHG emissions.”

“The big story is just how dramatically impactful beef is compared to all the others,” Prof. Gidon Eshel, at Bard College in New York state, told the Guardian.

“I would strongly hope that governments stay out of people’s diet, but at the same time there are many government policies that favor of the current diet in which animals feature too prominently. Remove the artificial support given to the livestock industry and rising prices will do the rest. In that way you are having less government intervention in people’s diet and not more.”

Destroy Carbon! Buy Carbon Permits For £6.47

By | | No Comments

Let’s all help destroy carbon! In a good way of course.

In Europe, big polluters need pollution permits. These EU permits provide a legal limit on CO2 emissions. However there are too many permits, meaning there’s little incentive to reduce pollution and the millions of tonnes of extra CO2.

Sandbag’s Carbon Destruction initiative gives us the power to change this.

The permit price is now around €6 per tonne, and you can ‘buy to cancel’ permits via the Sandbag website for £6.47 (They make no profit on sales, and only cover admin costs).

The basic idea is that we buy the cancellation of an EU permit to stop companies purchasing the right to emit this carbon.

UK quietly slashes millions of tonnes of emissions

By | | No Comments

Sandbag recently released this article reviewing emissions targets and what action has been taken in the UK. They look at what is really going on in emissions trading and encourage lobbying to ensure fewer permits are handed out. They also buy up the permits already on the market, and destroy them.

“With little fanfare, the UK government cancelled 36 million tonnes of carbon pollution rights in May. These carbon allowances relate to the UK’s carbon budgets and cover emissions outside the ETS that could otherwise have been banked forward into future budgets. With the stroke of a pen this eliminates more greenhouse gas emissions than the country’s two largest coal-fired power stations emit each year. At Sandbag we’re hopeful that this act, plus cancellation of HFC carbon credits in the Netherlands, on the Shenzhen carbon market, and others, sets a precedent for the cancellation of enormous surplus of allowances on the EU ETS.”

Here comes the sun – Solar Energy

By | | No Comments

Top Documentary Films have posted this video on their site focussing on solar energy.

“If it were up to the sun, we would have no energy problem. Every half hour on the Earth’s surface, there is more than enough light to provide energy needs for the whole world in a year. We don’t have an energy problem, we have a conversion problem. If we are able to harvest sunlight in smart way, then we can prevent a global energy crisis.

That sounds nice but that does not mean it will succeed, at least that is what many different bodies want us to believe. It’s too expensive, takes too much space, too much material, it costs more energy than it brings, and it is still not efficient enough. While all these doubts play a role for solar energy in the distant future, it is still a marginal player in the global energy game. Back-light takes the edge off these myths and shows that a solar economy is much closer than we think. Next year, there are already rolling Giga Watts of solar cells on the conveyor belt. The industry has mastered the technology and the machines.

Radical German government measures have proved that it is possible. Villagers have completely installed solar power on empty lands. Power stations contribute to the network and where they are deserved. Many countries follow the German example: The Americans have their Grand Solar Plan and the French President Sarkozy is talking about a solar plan with the countries bordering the Mediterranean Sea. According to the Spanish electricity producers, oil companies will be left out. So what energy crisis? The sun is coming!”

What percentage of the investment required for our 2030 energy needs will be in renewables?

By | | No Comments

This week has seen several articles like this one from The Climate Group exploring what $ investment amount is currently required to meet our energy needs in 2030. Most importantly, citing what percentage of that figure will be invested in renewables.

Global Power Generation BNEF

It’s been proposed that two thirds of the near $8 Trillion required (that’s eight with twelve zeros) will go on renewables. That is still too conservative! If you reverse the figures that’s still a very uncool $2.5Tn spent on the wrong side of the fence.

More must, and in reality, will be invested in renewables.


* The political landscape is sliding aggressively towards climate policies that will affect real change where it’s most required. This proposed ruling from the EPA in the USA is a prime example.

* We can crack the energy storage conundrum. It’s highly likely with current breakthroughs and smart-grids. Plus if Graphene lives up to its promises, then expect step jumps in storage and transmission technologies in the very near future.

* Will coal be around and viable by 2030? Why invest in obsolescence?

* The cost of renewables has already hit marketable levels. This article from the Huffington Post highlights key elements from solar.

It won’t be long before ‘alternative’ energy is simply labelled – Energy.

#Interface at #Consense – The sustainable building trade fair

By | | No Comments

Consense - The sustainable building trade fairConsense – The international trade fair and congress for sustainable building, investment, operations and maintenance exhibited over the last few days in Stuttgart.

It’s a chance to meet the leaders from across the world of sustainability. The joint offer of trade fair and congress makes Consense a cross-sector knowledge platform. Companies present the latest materials, products and construction systems. Experts discuss current issues regarding sustainable building, investment, operation and maintenance.

Interface had a stand with a novel way of getting our message across! What better way to take the transparency message to our customers and opinion leaders than having the EPD results of various products inside real ice? This is EPDs on the rocks!

Consense Sustainable Building Ice 2 Consense Sustainable Building Ice Consense Interface Sustainable Building Ice Consense Sustainable Building Ice 1

Of course the message of transparency is all very well on its own but much stronger when accompanied by a real world product to prove performance.  So we previewed Microsfera, our product with the lowest carbon footprint in the market (by far) – 3kgCO2/m2 cradle to gate.

The embodied impact of cement

By | | No Comments

Corporate Sustainable Development Report 2013

The publication of Holcim’s sustainability report has made me think about the high embodied impacts that cement brings. Some progress is under way but it is not enough.

Here are the numbers:

Cement production is highly energy intensive. The energy to make one tonne of clinker was 3466MJ in 2013, a reduction from 4500MJ in 1990. But production has increased significantly. For example Holcim’s cement production has increased by almost 120% since 1990 and even energy from coal and pet coke has increased by 25% despite a 14% use of waste as an alternative fuel. So cement growth for Holcim is pushing for 25% growth in coal and pet coke.

The most worrying part is that Holcim is actually the best in the industry (lowest carbon intensity) with net emissions of 572kg of CO2 per tonne of cement.

They aim to reduce that by 25% by 2015 and are on track.

The cement industry could be much more ambitious. It’s easy to point fingers when we have achieved a 90% absolute reduction but that’s not my point. They have instant options, for example – they could reduce the reliance on clinker by using slag from blade furnaces and other alternative materials.

Outside of the industry there is a compelling argument to reduce the demand for cement. Buildings can be designed so that they use less cement and still deliver decent thermal mass and high insulating values. This offers huge opportunities and much more scope for innovation. Architects, urban planners and infrastructure developers have the biggest leverage.

That obviously cannibalises the cement industry but it also offers opportunity to a new business model that sells less tonnes and more value. Innovations at product level that lead to premium products and services will have to be the key driver to decarbonise the cement industry.
