Sustainable Purchasing

Ready to make more informed, sustainable purchasing decisions for your office? Contact rachel_martinez@harvard.edu to request the Sustainable Office Worksheet, a resource designed by the Harvard Office for Sustainability to help purchasers follow best practices.


GENERAL TIPS

Practice Patience

Be mindful about the harms of an immediacy economy (e.g., next-day deliveries may have a higher emissions footprint than a 2-day order).

Right-Size Orders

Avoid excess by right-sizing orders of office materials and food for events.

BPI Compostable

Choose Reusable & Compostable

Choose BPI-certified compostable products when reusables are not a viable option.

Consider health in the supply chain

Give preference to companies that have healthier and safer labor practices.

Prioritize durability

Purchase for quality and long-term durability, not quantity.

Reduce unnecessary packaging

Buy in bulk when needed to reduce unnecessary packaging.

New Perspectives in Ornithology

Harvard Museums of Science and Culture

Ornithology—the science of birds—is experiencing a renaissance. Today, a new generation of tools is transforming how we study birds—from global citizen-science platforms such as eBird to satellite remote sensing and drone-based fieldwork. New Perspectives in Ornithology: 21st Century Dispatches across the World of Birds (Oxford University Press, 2026) reveals how these technologies are reshaping our understanding of bird life and the challenges birds face in a rapidly changing world. Volume editors Scott Edwards and Michael Reed will introduce the book’s key themes including bird ecology, evolution, behavior, citizen science, and conservation. Book contributors Jingmai O’Connor and Elizabeth Derryberry will then address how fossils are enhancing our understanding of bird evolution and how novel studies of bird songs are providing insights into how birds communicate and respond to environmental change.
