The agreement signed late last month may be the beginning of a new era of collaboration on climate change as the three North American countries signed an agreement to push cleantech and fight climate change.
Good news everyone ! According to the International Energy Agency, global carbon emissions related to the energy sector ” stalled ” last year. This took place in a time of global economic growth (+3% globally).
To the UNEP : “The waste of a staggering 1.3 billion tonnes of food per year is not only causing major economic losses but also wreaking significant harm on the natural resources that humanity relies upon to feed itself. “
1.3 billion tonnes of food ! This has profound repercussions on our world as it emits up to 3.3 gigatonnes of carbon dioxide per year. If food waste were a country, it would be the world’s third largest, just behind the United States and China.
This also amounts to a staggering loss of no less than $750 billion – around 550 billion euros – as a third of the food produced globally goes to the bin uneaten.
As I noted last week, the prestigious International Energy Agency reported that despite some emission reductions from the United States and Europe, the world keeps on spewing more and more gigatonnes of greenhouse gases.
Luckily, the IEA proposes in its latest report four energy policies that would cut by eight percent the 2020 emissions compared to a business as usual scenario. This would amount to 3.1 Gt CO2 equivalent.
While these actions are not exactly what the worlds need to keep its climate as cool as it should be, they could be done at no net economic cost.
Oooops ! According to Cleantechies, a 1.5°C temperature rise ” could unleash more than 1,000 gigatons of carbon and methane currently trapped beneath Siberian permafrost and accelerate global climate change. “ 1.5°C is considered as the low level of potential climate warming to date. This is even more worrying as such quantities of greenhouse gases … Read more
According to a new study by the Institute of Mechanical Engineers “Between 30 and 50 percent of all the food that’s produced on the planet is lost and wasted without ever reaching human stomachs.”
Treehugger wrote a compelling article on how this is such a huge and awful waste as there are still hundred of million people around the world that are starving as I write those lines. This problem as many other implications.
Indeed, all this wasted food leads to methane emissions, the excessive production to more carbon dioxide and to less water in our water tables.
Within my current involvement with the local JCI, I have been collecting information about biodegradable waste and composting. This is a question of importance as more than 30 percent of French waste could be biodegradable.
Meanwhile, recyclable waste – paper, cartons, glasses – represent just one percent more and are sorted out and recycled. I thus believe food leftovers, fruits and vegetable peelings, coffee and tea waste belong to a special bin.
This would have a lot of advantages as we will see in today’s post and I hope this will be as common as sorting out recyclables in a decade.
Here is a smelly question : why are we putting together what Nature separates ? This is the question asked by a Swedish researcher about toilets. Putting urine and feces together is not a good idea as it is simply a waste of resources.
Moreover, flushing with liters and liters of perfectly drinkable water is a bad idea as water scarcity is already striking around the world and will spread as climate gets warmer.
Now here come scientists from Singapore with an idea that could revolutionize the way we dispose from our bodily waste.
Are we finally getting things right on climate change ? Not completely, but what happened last week may be a good omen for the Rio +20 conference. As I noted in a post published yesterday on Cleantechies : ” Further to the Camp David meeting last week, G8 leaders agreed to act on climate change … Read more
This is not as good as it should be as carbon dioxide is not tackled, but this new initiative might help us in mitigating climate change in the short to medium term and improves health of million of people.
According to various sources, the United States, China as well as other countries are willing to cut emissions of various short-lived greenhouse gases such as methane, soot (black carbon) and hydroflurocarbons (HFCs)
Of course, the fact that the main greenhouse gas is not included is a major problem, but the fact that the NASA recommendation are being followed is still good news.
What if we could in the same time slow down climate change, increase health and boost agriculture ? Is this too good to be true ? No, as to a NASA scientist we could do just that by focusing on both methane and soot (black carbon).
Out of the 400 ideas that were studied, these 14 were chosen as they have a direct and immediate impact on people’s lives. None of these methods are concerning carbon dioxide, which also have to be tackled in the meantime.
One of the main ways is switching to cleaner burning cookstoves. I have previously tackled this topic here and explained how this could save two million people per year.
I don’t talk about food often here. However, with so many starving people around the world, I should talk more about agricultural advances as feeding nine billion people by 2050 will be the biggest challenge ever faced.
