Global hot spot maps link consumers with impacts

A new model creates global hot spot maps to illuminate how what we buy pollutes the planet and where. The idea is to help governments, industries and individuals target areas for cleanup.

Food waste recycling not always the best idea

With Norway as a case study, a first-ever effort to quantify the benefits of recycling food waste versus preventing it shows prevention is the best policy. But Norway continues to invest significant funds in biogas facilities for food waste recycling.

ABC — anything but coal

Policymakers, industry and government officials will have to invest US $2.5 trillion for electricity generation over the next 20 years. A new report presents the environmental costs and benefits linked to different renewable energy sources, and makes one thing abundantly clear: anything is better than coal.

Climate: a challenging type of justice

What makes a fair climate agreement? The fight for justice has been one of the biggest problems in all international climate discussions. The summit in Paris will likely be no exception.

Two tickets to Paris to talk about carbon cuts

NTNU was given only two admission tickets to the UN climate talks in Paris later this month. The tickets will be used in part by two researchers from the university’s Industrial Ecology Programme to give a workshop about carbon accounting.

Check your climate impact

Ducky will help you find out how much your car trip or yesterday’s dinner has affected the environment. The app creators hope that competing against yourself and your friends will contribute to reducing CO2 emissions.

Timing is everything for renewable energy use

There’s no time to waste in shifting to renewable energy sources if we are to avoid dangerous climate change. That’s especially true when it comes to bioenergy, which causes a temporary increase in CO2 levels that is later removed as replacement biostocks grow.

Fish farming gobbles up phosphorus

Fish farming is the largest source of phosphorus emissions in Norway, generating about 9,000 tonnes a year. Finding ways to reuse the waste from the fish farming industry could cut consumption of this important and increasingly scarce resource.

Recycling aluminium, one can at a time

Producing pure aluminium from ore accounts for as much as 1 per cent of all greenhouse gas emissions worldwide. Recycling is the best way to reduce that carbon footprint – but manufacturers and recycling companies will have to plan carefully to avoid problems with impurities that accumulate in recycled aluminium over time.

Carving up the global carbon pie in a new way

When negotiators come to Paris this December to discuss a binding and universal agreement on controlling climate change, they have to know how much each country contributes to the greenhouse gas emissions problem. A new method offers the best hope yet for accurately accounting for these emissions by providing the right incentives and assigning fair responsibilities.

Low-carbon electricity future is clean and feasible

The countries of the world wrapped up preliminary climate talks in Lima, Peru this weekend with an agreement on how the UN’s 194 countries will tackle climate change. The agreement comes in advance of major negotiations scheduled for Paris next year to designed to curb the world’s production of greenhouse gases. In a publication from earlier this year, researchers at NTNU’s Industrial Ecology Programme report that the low-carbon future that would result from curbing greenhouse gas emissions is both feasible from a practical standpoint, and will also substantially reduce air pollution.

Hope for the climate, hope for clean air

Climate talks in New York this week have offered a glimmer of hope that the world’s political leaders finally understand the need to act to curb global warming. An NTNU researcher says that these actions will have a beneficial side effect: cleaner air in some of the most polluted places on the planet.

Cool climate – clean planet

Ever-rising greenhouse gas emissions and the potential need to deploy untested and expensive climate engineering technologies are just two of the many bits of bad news in the Intergovernmental Panel on Climate Change’s new report on “Mitigation of Climate Change”, released on 13 April.

A global challenge

Three climate researchers talk about the latest report from Intergovernmental panel on climate change (IPCC). In English, French and Italian.

One of 830 scientists behind the climate report

When the Intergovernmental Panel on Climate Change releases its new report on “Mitigation of Climate Change” on 13 April, NTNU Professor Edgar Hertwich’s contribution as one of the lead authors of the Energy Systems chapter will amount to exactly 5 pages.
