The Earth's oceans absorb most of the heat which is retained.

It is now recognised by many organisations that employing (and training if / as necessary) local peo-

ple is not only humane but also helps the local economy, often keeping communities alive which

might otherwise wither.

2050 is the correct answer.

There is an issue with the dates for many organisational targets. They are far too pessimistic to be

genuinely effective in dealing with sustainability issues. Even if you didn't know DHL's target date,

you may know that many large companies and governments don't quite feel the urgency of the

'emergency'. There are many opinion-leaders who feel that a sense of urgency needs to be injected.

GHG is an abbreviation for 'greenhouse gas'.

Greenhouse gases create a 'greenhouse effect' on the planet- ie warming it.

Other question on the subject of GHG appear in these tests.

Transport.

Think about it: vehicle engine noise, sirens, rail, overhead aircraft. With engine noise often being a

constant buzz.

True.

Environmental issues are part of CSR, but only part of it. There are other parts eg social / people as-

pects.

True.

EIAs can be direct, indirect or cumulative.

The most appropriate answer is: A socially responsible buying approach would require not only minimum wage, but in some circum- stances greater than minimum wage as this may not be sufficient to support an employee to live de- cently. This question is inspired by a recent visit to a country where there is a statutory minimum wage, but it is so low that most people would be unable to provide shelter and food based on that income. The wage to which I refer is less than $1 per hour.

Cube.

Indicating that people, unless made consciously aware, tend to under-use the dimension of height,

using depth and breadth readily. For illustrations, check aerial photographs of many US cities

(sprawl), or check the inside of your fridge. In warehousing and storage, such an approach can be a

very costly error - so 'maximise use of the cube'.

'Hydro' means 'water'.

As a child in Scotland, I remember visiting a hydro-electric power station, where a dam had been

built across a river, with the dammed water used to generate electric power.

As a slightly older child, I used to routinely watch a BBC2 test television broadcast which was all

about the building of the Kariba dam for a similar purpose, with huge environmental and social con-

sequences. Many other such dams have been build since, including, for example, the Aswan dam.

Often such projects attract criticism because of the effects on the environment as well as on people.
