Can 365 Years of Climate History Help Prevent Crises in East Africa?

For a long time, a majority of African countries have not been proactively mitigating the negative impact of drought and flood events.

What You Can’t See Can Hurt You: Improving the Air We Breathe Indoors

Air quality is no longer something we can judge by our senses alone, especially indoors. Volatile organic compounds (VOCs), particulates, carbon monoxide, and radon are among the chief culprits for poor indoor air quality, along with dust, mold, and bacteria. Building design, interior design, and building maintenance are key factors influencing your “micro-climate” – that is, the space in which you live and work, and specifically, the air you breathe. Optimizing your micro-climate involves smart design, purchasing, and an understanding of the air around you.

Domtar Sustainability: Pulling Our Weight

Unlike their counterparts in Pulp and Paper, our logistics colleagues in Personal Care don’t have a weight problem. Quite the opposite, they struggle to put it on.

Optimizing transportation efficiency is the objective for both of our divisions. They both strive to get the most product in a trailer. One is weight constrained. The other has a space issue.

The reason for the difference is that personal care products are lightweight. It is easy to fill a trailer and be well within the regulated weight limit. The challenge for our logistics colleagues in Personal Care is how to max out the allowable weight limit.
