This box weighs a ton. What's inside?

Last year at this time, rice cost 330 a ton.

At this low price, companies have little incentive to cut back on their CO2 emissions and little faith that a market based incentive will return.

Recent market transactions on the European Climate Exchange place the value of carbon somewhere between 10 and 100 per ton.

Moreover, compared to natural gas and crude oil, coal is much cheaper per ton of CO2 released.

The idea is that power plants and other large fossil fuel users should capture the CO2 and pump it into permanent underground storage sites, such as old oil fields.

This will cost, say, 30 per ton of CO2 that is stored, so businesses will need an incentive to do it.

For example, say that the EU decides to put up a diamond studded wind turbine at the Berlaymont headquarters, which will save one ton of CO2 each year.

Permits that used to sell for more than 30 per ton before the crisis now trade for under 10.

Green and Galiana propose limiting carbon pricing initially to a low tax (say, 5.00 a ton) to finance energy research and development.

We put a ton of virus up this guy's nose. So I mean, we wanted it to work. He really had a cold.

African farmers produce roughly one ton of grain per hectare, compared with more than four tons per hectare in China, where farmers use fertilizers heavily.

First, a carbon price in the range of 20 25 per ton of CO2 by 2020 is key to mobilizing climate finance at this level.

What this means is that we should be prepared to pay an awful lot to stop global warming, but anything more than 7 a ton would be economically indefensible.

If large emitting countries were to impose carbon prices of 30 per ton of CO2, they could generate fiscal revenues amounting to about 1 of their GDP.

Some countries, like Norway and Sweden, long ago introduced a tax on CO2 emissions to reflect a social cost of 100 per ton, or even higher.

Perhaps it is time to try another approach a commitment by each country to raise the price of emissions (whether through a carbon tax or emissions caps) to an agreed level, say, 80 per ton. Countries could use the revenues as an alternative to other taxes it makes much more sense to tax bad things than good things.

Because each barrel of oil emits roughly 0.3 tons of CO2, a carbon tax of, say, 40 per ton of CO2 implies an oil tax of just 12 per barrel.

If these countries earmarked just 2 per ton of CO2 for global financing organizations like the new Green Climate Fund and the regional development banks, they would transfer around 36 billion per year.

Perhaps it is time to try another approach a commitment by each country to raise the price of emissions (whether through a carbon tax or emissions caps) to an agreed level, say, 80 per ton.

Only Europe has tried to make a serious shift away from carbon emissions, creating a system that requires each industrial emitter to obtain a permit for each ton of CO2 emissions.

Inside I rejoice, as she is so much easier to dress than, say, Britney Spears, Christina Aguilera, who has recently gained about a ton (please, understand I am exaggerating), or the very young Selena Gomez.

If we feed our food waste which is the current government favorite way of getting rid of food waste, to anaerobic digestion, which turns food waste into gas to produce electricity, you save a paltry 448 kilograms of carbon dioxide per ton of food waste. It's much better to feed it to pigs.

In other words, brave Ukranian polizei removed our servers without any legal basis, and now they will probably extort money (or a tonne of salted pork fat?) from us for the return of our own equipment, and if that doesn't work they will sell it.

In a cap and trade system, the government sets total allowable national emissions of CO2 per year and requires any firm that causes CO2 emissions to have a permit per ton of CO2 emitted.

It would be smarter to act cautiously by implementing a low carbon tax of about 0.5 per ton about 0.5 US cent per gallon of gas or 0.1 euro cent per litre of petrol and increase it gradually through the century.
