Colgate, LinkedIn and #EveryDropCount campaign

Once again LinkedIn improve his popularity and show that their social media website is used by most known and the the largest companies today. This time I will write Colgate-Palmolive company which use LinkedIn for their promotion and advertisement.

When I start to check their last updates I was surprised when I saw they way of advertising and promotion.
In one post their promote their campaign and encourage consumers to save water by turning off the faucet while brushing their teeth.

I think that this is the best way of promoting one company, because they show their care about community and environment. What do you think?

They also invite all members of their site to visit https://lnkd.in/ejk8JN7 and take the pledge to make every drop of water count! On this link members should select number of people in their household and program will automatically account the number of gallons of water that are saved every day. 
They call their campaign #EveryDropCounts.

 I'm interested to hear whether you as new managers and entrepreneurs will use something like this campaign to promote your business?
