A lot.

Governments changed.

Economies changed.

Markets crashed.

New technologies changed industries and societies.

But what hasn't changed

is IBM's commitment to transparent environmental reporting.

It is an area that just doesn't take a day off.

You have to be constantly improving.

Today, every company issues an environmental report.

But it wasn't always that way.

In the 1990's, we were one of the few multinational companies to do

a comprehensive environmental report.

But at the time, I think we recognized

it really forces companies to take action.

And that very beginning of

corporate environmental reporting from 30 years ago

has taken off like wildfire.

Today, every generation of our hardware

needs to be more efficient than the previous generation.

Buildings account for about 40% of the world's energy use.

So if we can use data analytics

we can make a lot of progress

in reducing the energy use of those buildings.

Reporting our environmental impacts,

it's not just about feeling good about ourselves.

It's about our values.

You shouldn't be embarassed to disclose how your operations are impacting the environment.

We're very fact-driven.

We try to understand the problem, and IBM's impact,

and what we can do to change our operations.

What matters most in the end

is conserving energy,

actually consuming renewable electricity,

and truly avoiding, eliminating, or reducing emissions.

We have the solution, we have the desire, and

whether it's clients, the government, or in private sector,

they have the needs.

We just need to match those things together.
