7 Sustainable Holiday Gift Ideas
December 14, 2016 08:39 PM - Bill Roth

Tis the season, and we all are buying gifts. The question is how to do so without saddling friends and families with returns, throwaway gift paper or mounds of fattening desserts.

Here are seven gift ideas that show you care for not only the person receiving the gift, but also for people and planet.

1. Make a donation

This is my favorite gift. I give to a charity that I think aligns with the gift recipient’s passions. Does she love dogs? A gift in her name to the humane society always results in a truly genuine positive response. What family is not touched by health issues like heart disease or cancer? A gift to the Heart Association or Cancer Society is a thoughtful and meaningful way of saying you care. Looking for a charity? I use Charity Navigator to find credible nonprofits. The site also has top 10 lists that cover a diverse range of charities.

Thanksgiving Dinner's Carbon Footprint: A State-by-State Comparison
November 23, 2016 07:29 AM - Carnegie Mellon University

The environmental impact of your Thanksgiving dinner depends on where the meal is prepared.

Carnegie Mellon University researchers calculated the carbon footprint of a typical Thanksgiving feast – roasted turkey stuffed with sausage and apples, green bean casserole and pumpkin pie – for each state. The team based their calculations on the way the meal is cooked (gas versus electric range), the specific state’s predominant power source and how the food is produced in each area.

They found that dinners cooked in Maine and Vermont, states that rely mostly on renewable energy, emit the lowest amounts of carbon dioxide, a greenhouse gas that is tied to climate change. States that use coal power, such as Wyoming, West Virginia and Kentucky, have the highest carbon dioxide emissions.
