WHY BRING SERVICES INTO ‘THE CLOUD’

16. THANK YOU

17. • Is “Green” purely a marketing message
– Do we think Green credentials are important to our
customers?
– Do people currently using Green credentials in the
sales process?
– Can Green have a positive financial impact
– Do we believe CRC “tax” initiatives will become more
onerous on UK business in the future?

assurance?
