The European commission

The talk with present the key results of the IPCC Working Group III 5th assessment report. Concluding four years of intense scientific collaboration by hundreds of authors from around the world, the report responds to the request of the world's governments for a comprehensive, objective and policy neutral assessment of the current scientific knowledge on mitigating climate change. The report has been extensively reviewed by experts and governments to ensure quality and comprehensiveness.

Climate change 2014 - Mitigation of climate change

For base year 2010, anthropogenic activities created ~210 (190 to 230) TgN of reactive nitrogen Nr from N2. This human-caused creation of reactive nitrogen in 2010 is at least 2 times larger than the rate of natural terrestrial creation of ~58 TgN (50 to 100 TgN yr−1) (Table 6.9, Section 1a). Note that the estimate of natural terrestrial biological fixation (58 TgN yr−1) is lower than former estimates (100 TgN yr−1, Galloway et al., 2004), but the ranges overlap, 50 to 100 TgN yr−1 vs. 90 to 120 TgN yr−1, respectively). Of this created reactive nitrogen, NOx and NH3 emissions from anthropogenic sources are about fourfold greater than natural emissions (Table 6.9, Section 1b). A greater portion of the NH3 emissions is deposited to the continents rather than to the oceans, relative to the deposition of NOy, due to the longer atmospheric residence time of the latter. These deposition estimates are lower limits, as they do not include organic nitrogen species. New model and measurement information (Kanakidou et al., 2012) suggests that incomplete inclusion of emissions and atmospheric chemistry of reduced and oxidized organic nitrogen components in current models may lead to systematic underestimates of total global reactive nitrogen deposition by up to 35% (Table 6.9, Section 1c). Discharge of reactive nitrogen to the coastal oceans is ~45 TgN yr−1 (Table 6.9, Section 1d). Denitrification converts Nr back to atmospheric N2. The current estimate for the production of atmospheric N2 is 110 TgN yr−1 (Bouwman et al., 2013).

Renewable Power-to-Gas: A technological and economic review

Purpose



– A dense urban structure cuts down traffic emissions. It also promotes waste heat use and storage possibilities as a form of district heating. However, quality elements associated with detached houses, such as tranquillity and self-expression possibilities, may be lost. Better building quality and alternatives to private car use can enable these elements in smaller spaces, which is assessed here. The paper aims to discuss these issues. 




Design/methodology/approach



– A technology set for an imaginary high-quality (HQ) apartment house is discussed by assessing increased embedded energy of the building structure, due to the HQ measures. HQ solutions include visual barriers, increased sound insulation, roof terraces, large windows, apartment adaptability, bike sheds, electrical cargo bikes and advanced energy solutions. 




Findings



– The increased construction and heating energy use in HQ buildings can be offset if car use is reduced by 10-15 per cent. There is a greater possibility of achieving this reduction if HQ housing can make urban densification more readily acceptable by demonstrating, that good quality housing can exist both in smaller building lots as well as in smaller apartments. 




Originality/value



– The quality issue brings a novel perspective to estimating the environmental impacts of built environment solutions. The approach here is quite simple, but the issue can be discussed more. That is, how much total resource input can be decreased, if the target is not to produce square metres but rather the necessary elements to have a good quality of life.

A concept to combine the different housing alternative advantages

Possible bottlenecks in clean energy transitions: Overview and modelled effects – Case Finland

The demand for data services, predominantly provided by data centers, has grown rapidly in the last decade as global internet traffic has increased. To provide data services, data centers consume vast amounts of electricity, making them a significant prospect to reduce carbon emissions in the power sector. Thus, efforts to de-carbonize and integrate renewables into the energy supply of data centers will be essential to curb carbon emissions of these facilities in the future. For this purpose, both utilization of waste heat and wide-scale implementation of local renewable energy sources in data centers are needed. In this paper, we show how a solar PV system could be integrated into a forthcoming data center in Finland, with options for battery storage and prosumer grid utilization. We also evaluate the cost-effectiveness of this approach in a Nordic climate with various levels of self-production.
