The science is clear, we must cut greenhouse gas emissions in half by 2030 to avoid the worst climate outcomes.  Our corporations must not only commit to meeting their share of greenhouse gas emission reductions but also to achieving the world's emission reductions as a whole.  We need their support or the world will be a much different place.

If corporations commit to helping the world achieve the necessary greenhouse gas emission reductions for the next six years, they can contribute political and financial support to the solutions and help to move the conversation from denial to getting the job done.  And if the top corporations in every field -- especially finance where their reach is greater than just their own field -- do so, many others will follow.
