Jason Clay: How big brands can help save biodiversity

Convince just 100 key companies to go sustainable, and WWF's Jason Clay says global markets will shift to protect the planet our consumption has already outgrown. Hear how his extraordinary roundtables are getting big brand rivals to agree on green practices first -- before their products duke it out on store shelves.

Jason Clay is a WWF vice-president who works with big corporations to transform the global markets they operate in, so we can produce more with less land, less water and less pollution.

Scientists create 'dry water

The substance resembles powdered sugar and could revolutionise the way chemicals are used.

Each particle of dry water contains a water droplet surrounded by a sandy silica coating. In fact, 95 per cent of dry water is ''wet'' water.

Scientists believe dry water could be used to combat global warming by soaking up and trapping the greenhouse gas carbon dioxide.

Tests show that it is more than three times better at absorbing carbon dioxide than ordinary water.

Dry water may also prove useful for storing methane and expanding the energy source potential of the natural gas.

Dr Ben Carter, from the University of Liverpool, presented his research on dry water at the 240th National Meeting of the American Chemical Society in Boston.

He said: ''There's nothing else quite like it. Hopefully, we may see dry water making waves in the future.''

Water CO2 calculator for UK homes goes online

A website that helps people to work out how much CO2 is being emitted to heat water in their homes has gone online.

Produced by the Energy Saving Trust (EST), it also suggests ways that users can save water and energy, as well as cutting their carbon footprint.

The Trust says CO2 from energy used to heat water in UK homes accounts for 5% of the nation's total carbon emissions.

Yet, it adds, water use is the "forgotten energy saving opportunity" by homes, businesses and policymakers.

The EST produced the calculator as an interactive, "easy to understand" tool for people to make the link between water efficiency and energy efficiency, explained Andrew Tucker, EST's water strategy manager.

Energy used in the UK water sector accounts for about 6% of the nation's total CO2 emissions, 89% of which is a result of homes and businesses heating the water.

Figures from the Trust estimate that heating water accounts for about 30% of the average household's energy bills.

Sperm whale faeces offset CO2 emissions

In a somewhat unusual research project, scientists have found that sperm whale faeces may help oceans absorb carbon dioxide from the air.

Australian researchers calculate that Southern Ocean sperm whales release about 50 tonnes of iron each year.

This stimulates the growth of tiny marine plants - phytoplankton - which absorb CO2 during photosynthesis.

They note in the Royal Society journal Proceedings B that in the end, this also provides more food for the whales.

Phytoplankton are the basis of the marine food web in this part of the world, and the growth of these tiny plants is limited by the amount of nutrients available, including iron.

Rich countries accused of carbon 'cheating'

Some rich countries are seeking new rules under the UN climate convention that campaigners say would allow them to gain credit for "business as usual".

Russia, Australia, Canada and some EU countries are among the accused.

The rules relate to land-use change, which can either release or absorb carbon, depending mainly on whether forests are planted or chopped down.

Rich countries, apart from the US, could account for about 5% of their annual emissions through this loophole.

The US is not involved in these negotiations because the proposals fall under the Kyoto Protocol, of which it - alone among developed countries - is not a part.
