Earth Talk: Cap and trade strategies to reduce carbon emissions

Roddy Scheer

Cap and trade, whereby big polluters must pay to emit greenhouse gases against a capped total amount that is reduced over time—has been in effect across the European Union (EU) since 2005. This so-called Emissions Trading System (ETS) requires 11,000 of the largest electric and industrial facilities in 28 European countries to participate.

Earth Talk: Synthetic Biology

Roddy Scheer

Synthetic biology (or “synbio”) refers to the design and fabrication of novel biological parts, devices and systems that do not otherwise occur in nature. Many see it as an extreme version of genetic engineering (GE). But unlike GE, whereby genetic information with certain desirable traits is inserted from one organism into another, synbio uses computers and chemicals to create entirely new organisms.
