What are negative emissions?

Most proposals to limit global temperature rises to well below 2° Celsius rely on ‘negative emissions’ – the removal of carbon from the atmosphere.

This can be done naturally, such as by protecting and restoring degraded forests so they become carbon sinks. Some also claim that it can be done through geo-engineering, for instance by burning bioenergy, capturing the carbon released, and pumping it into underground geological reservoirs. This is known as Bioenergy, Carbon, Capture and Storage (BECCS).

Fern believes there are three main risks in relying on geo-engineering projects:

  1. They are used as an excuse to keep burning fossil fuels despite unproven benefits
  2. They will have unacceptable ecological and social impacts if used at an industrial scale
  3. They cannot ensure stored carbon is not released through human or natural forces, including climate change

For more information see the outcomes of a meeting Fern hosted on negative emissions.

Double Jeopardy: coal's threat to forests

Coal is the single biggest contributor to man-made climate change, while deforestation accounts for up to one-sixth of CO2 emissions. So when forests are torn down to make way for coal mines the danger to the planet intensifies.

Comment on the COP21 - a forest perspective

Forests barely feature in the draft text, but runaway climate change could devastate the forests which more than a billion people directly rely on for their survival. Forests also play a crucial role in regulating the climate. Whichever way you look at it, the outcome of the Paris agreement is also an outcome for forests.
 
Kate Dooley  is in Paris, tracking the developments in the UN climate summit. She has written this overview of the talks from a forests perspective for Fern. Check back later in the  week for  further perspectives from Kate and other contributors.

Coal’s hidden ‘double whammy’: global map reveals 12 million hectares of forest at risk

A new report released at the United Nations climate change conference in Paris reveals that a forest area larger than Portugal is at risk from coal mining worldwide, with forests in Australia, Canada, Indonesia, India, Colombia and the United States particularly vulnerable.

The report, which provides the first global map of where forests are being destroyed for coal mines, argues that granting land rights to forest communities can keep forests standing and coal in the ground
