Climate Change Doug Wilson Corporate Affairs Manager

Scientists believe that global warming is real. Human beings seem to be responsible. The 10 warmest years on record have occurred since 1995. Last winter was the warmest winter ever recorded in the UK. Weather experts predicted that 2007 would be the hottest year yet. It is now 0.7 °C hotter than pre-industrial times. Sounds small, but it was only 4°C cooler during the last ice age. If the planet get a couple of degrees hotter, who knows what might happen. What is Climate Change?

Scientists believe that global warming is real.

Human beings seem to be responsible.

The 10 warmest years on record have occurred since 1995.

Last winter was the warmest winter ever recorded in the UK.

Weather experts predicted that 2007 would be the hottest year yet.

It is now 0.7 °C hotter than pre-industrial times.

Sounds small, but it was only 4°C cooler during the last ice age. If the planet get a couple of degrees hotter, who knows what might happen.

What is climate change? Gases collect in the atmosphere and cause it to trap more of the sun’s warmth. These gases are often referred to as ‘greenhouse gases’. The term ‘carbon’ is sometimes used as shorthand as most of the gases contain carbon molecules. The main culprit is Carbon Dioxide (CO 2 ) which is caused by burning fossil fuels (coal, gas and oil) and deforestation. Methane (CH 4 ) is emitted by landfill sites, rice paddies and in many agricultural processes e.g. raising livestock. HFCs are synthetic gases invented to replace CFCs – they are used in refrigerators.

What is Tesco doing? Measuring our impact: The global Tesco business emits 4.1 million tonnes of “carbon” (greenhouse gases) every year. This is our “carbon footprint” Business Travel Group split of emissions by source for 2006/07 57% 25% 11% 6% 1% Grid Electricity Diesel Natural Gas Refrigerant

50% cut in emissions from existing buildings by 2020 50% cut in carbon footprint of all new stores built by 2020 50% cut in CO2 created per case of goods delivered by 2012 What is Tesco doing? Setting targets:

50% cut in emissions from existing buildings by 2020

50% cut in carbon footprint of all new stores built by 2020

50% cut in CO2 created per case of goods delivered by 2012
