A biosolar roof is one that has installed both vegetation and solar panels on the top of a building. Does the presence of one obstruct the other, or do they in fact enhance each other? The answer is the latter, explain Peter Irga, Fraser Torpy, Eamonn Wooster, Charles Sturt, Robert Fleck at the University of Technology Sydney and Jack Rojahn at the University of Canberra who summarise their study. The vegetation cools the panels closer to their … [Read more...]
Event summary: “Bioenergy after REDIII – sustainable, climate neutral fuels for industry, transport and negative emissions”
Sara Stefanini provides a written summary of our panel discussion held on Wednesday 4th October 2023. It’s a full summary of the 75 minute discussion, and begins conveniently with a summary of the highlights. Under the recently revised Renewable Energy Directive (REDIII) bioenergy can be counted towards the renewable energy targets – provided that it meets strict sustainability criteria. Bioenergy already accounts for 60% of the EU’s renewable … [Read more...]
All estimates of the ‘cost’ of climate action should include the savings and benefits
Too many climate mitigation scenarios calculate the cost of that transition without measuring the savings and benefits, explain Alexandre Köberle and Joeri Rogelj at Imperial College London, Toon Vandyck at the EC's Joint Research Centre, and Celine Guivarch at the Centre International de Recherche sur l’Environnement et le Developpement, writing for Carbon Brief. This leads to a pessimistic view of the challenges ahead, and public aversion to … [Read more...]
Wind and Solar expansion is a threat to biodiversity. But by how much?
Wind and solar take up space, so a massive expansion will have an effect on biodiversity. But how much? Sebastian Dunnett at Hammersmith and Fulham Council in London, writing for Carbon Brief, summarises his co-authored paper that takes the latest data on wind and solar and its multiple impacts (a few are good, surprisingly) on the environment. The conclusion is that the consequences of land overlap need not be as severe as feared, provided … [Read more...]
Land Use and Forestry: existing LULUCF rules allow EU’s carbon sink to decrease. Change them
The EU’s current Regulations for Land Use, Land Use Change and Forestry (LULUCF) allow the region’s carbon sink to decrease, explains Ulriikka Aarnio at CAN Europe. It’s due to exclusions and a lack of transparency and proper accounting for emissions. As a result, the EU’s carbon sink has already decreased significantly in the last few years, extracting only 265 Mt of CO2 in 2019. Different activities both emit and absorb carbon. 2019 saw 135 Mt … [Read more...]
