Politikens roll för näringslivets klimatomställning
- 2024
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Efter Parisavtalet 2015 har synen på politikens roll i klimatomställningen gradvis förändrats. Klimatfrågan betraktas numera som en viktig del av samhällsutvecklingen snarare än som ett isolerat problem. En central fråga i den nya klimatpolitiken är: hur kan samhällsutvecklingens inriktning påverkas så att ekonomin fortsätter utvecklas samtidigt som klimatmålet om nettonollutsläpp till 2050 nås? För att klara av en klimatomställning inom utsatt tid krävs strukturella förändringar av ekonomin. I denna rapport diskuteras politikens roll i att möjliggöra för näringslivet att ställa om, med utgångspunkt i forskning och lärdomar från historiska strukturomvandlingar. Författarna granskar vilka åtgärder och områden som klimatpolitiken behöver fokusera på för att Sverige, liksom övriga Europa, ska kunna uppnå det globala klimatmålet att begränsa temperaturökningen.

- RATIONALE: Chronic obstructive pulmonary disease (COPD) includes respiratory symptoms and chronic airflow limitation (CAL). In some cases, emphysema and impaired diffusing capacity for carbon monoxide (DLCO) are present, but characteristics and symptoms vary with smoking exposure.OBJECTIVES: To study the prevalence of CAL, emphysema and impaired DLCO in relation to smoking and respiratory symptoms in a middle-aged population.METHODS: We investigated 28,746 randomly invited individuals (52% women) aged 50-64 years across six Swedish sites. We performed spirometry, DLCO, high-resolution computed tomography (HRCT) and asked for smoking habits and respiratory symptoms. CAL was defined as post-bronchodilator forced expiratory volume in 1 second divided by forced expiratory volume (FEV1/FVC)<0.7.RESULTS: The overall prevalence was for CAL 8.8%, for impaired DLCO (DLCOCONCLUSIONS: In this large population-based study of middle-aged people, CAL and impaired DLCO were associated with common respiratory symptoms. Self-reported asthma was not associated with CAL in never-smokers. Our findings suggest that CAL in never-smokers signifies a separate clinical phenotype that may be monitored and, possibly, treated differently from smoking-related COPD.

Early transfusion patterns improve the Molecular International Prognostic Scoring System (IPSS-M) prediction in myelodysplastic syndromes
- 2024

Tidskriftsartikel (refereegranskat)abstract
- Background The Molecular International Prognostic Scoring System (IPSS-M) is the new gold standard for diagnostic outcome prediction in patients with myelodysplastic syndromes (MDS). This study was designed to assess the additive prognostic impact of dynamic transfusion parameters during early follow-up. Methods We retrieved complete transfusion data from 677 adult Swedish MDS patients included in the IPSS-M cohort. Time-dependent erythrocyte transfusion dependency (E-TD) was added to IPSS-M features and analyzed regarding overall survival and leukemic transformation (acute myeloid leukemia). A multistate Markov model was applied to assess the prognostic value of early changes in transfusion patterns. Results Specific clinical and genetic features were predicted for diagnostic and time-dependent transfusion patterns. Importantly, transfusion state both at diagnosis and within the first year strongly predicts outcomes in both lower (LR) and higher-risk (HR) MDSs. In multivariable analysis, 8-month landmark E-TD predicted shorter survival independently of IPSS-M (p < 0.001). A predictive model based on IPSS-M and 8-month landmark E-TD performed significantly better than a model including only IPSS-M. Similar trends were observed in an independent validation cohort (n = 218). Early transfusion patterns impacted both future transfusion requirements and outcomes in a multistate Markov model. Conclusion The transfusion requirement is a robust and available clinical parameter incorporating the effects of first-line management. In MDS, it provides dynamic risk information independently of diagnostic IPSS-M and, in particular, clinical guidance to LR MDS patients eligible for potentially curative therapeutic intervention.

Contribution of carbon pricing to meeting a mid-century net zero target
- 2024

Ingår i: Climate Policy. - : Informa UK Limited. - 1469-3062 .- 1752-7457. ; :1, s. 1-12

Tidskriftsartikel (refereegranskat)abstract
- A mid-century net zero target creates a challenge for reducing the emissions of emissions-intensive, trade-exposed sectors with high cost mitigation options. These sectors include aluminium, cement, chemicals, iron and steel, lime, pulp and paper and petroleum refining. Available studies agree that decarbonization of these sectors is possible by mid-century if more ambitious policies are implemented soon. Existing carbon pricing policies have had limited impact on the emissions of these sectors because their marginal abatement costs almost always exceed the tax rate or allowance price. But emissions trading systems with free allowance allocations to emissions-intensive, trade-exposed sectors have minimized the adverse economic impacts and associated leakage. Internationally coordinated policies are unlikely, so implementing more ambitious policies creates a risk of leakage. This paper presents policy packages a country can implement to accelerate emission reduction by these sectors with minimal risk of leakage. To comply with international trade law the policy packages differ for producers whose goods compete with imports in the domestic market and producers whose goods are exported. Carbon pricing is a critical component of each package due its ability to minimize the risk of adverse economic impacts on domestic industry, support innovation and generate revenue. The revenue can be used to assist groups adversely impacted by the domestic price and production changes due to carbon pricing and to build public support for the policies. Key policy insights A country with a mid-century net zero GHG emission target likely will need to implement more ambitious mitigation policies soon for emission-intensive sectors such as aluminium, cement, chemicals, iron and steel, lime, pulp and paper and petroleum refining. More ambitious mitigation policies are likely to vary by country and be implemented at different times, creating a risk of leakage due to industrial production shifts to other jurisdictions. More ambitious mitigation policy packages, compatible with international trade law, that a country can implement to reduce emissions from these sectors with minimal risk of leakage are available but differ for producers whose goods compete with imports in the domestic market and those whose goods are exported. Carbon pricing is a critical component of each package due its ability to minimize the risk of adverse economic impacts on domestic producers, support innovation and generate revenue.

Högskolepedagogisk debatt : Rättssäker examination och artificiell intelligens
- 2024
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Det föreliggande temanumret har fått titeln Rättssäker examination och artificiell intelligens (AI). Vad som impliceras är någon form av relation mellan de båda fenomenen. Lärosäten är hårt pressade att reda ut vilken den relationen egentligen är. Det finns inga givna svar så det är bäddat för att vi skall bli den sortens kunskapsorganisationer vi är menade att vara – sökande, prestigelösa och öppna för debatt om hur AI-applikationer inom i stort sett hela vår verksamhet kan användas på ett försvarbart sätt.

Towards carbon neutrality : Transition pathways for the Chinese ethylene industry
- 2024

Ingår i: Renewable and Sustainable Energy Reviews. - 1364-0321. ; 199

Tidskriftsartikel (refereegranskat)abstract
- Ethylene is one of the most important products in the emissions-intensive petrochemical industry. Decarbonizing the ethylene industry is thus important for achieving global carbon neutrality. This study is the first to explore future long-term zero-emissions production pathways for the ethylene industry in China, the world's biggest ethylene producer. An optimization model was built in the context of China's carbon neutrality target of 2060. Four scenarios were developed where the policy ambitions for climate mitigation and for plastic management including waste were varied. Based on this, authors assessed the cumulative total emissions, technology options, future geographical location of ethylene production, and policy challenges associated with each scenario. This is also the first time that scope 3 emissions from waste incineration are included, motivated by the short lifetime of most ethylene products. Results show the cumulative CO2 emissions for the scenarios differ considerably, ranging from 4.3 to 7.8 Gt, even if carbon neutrality by 2060 is achieved in all scenarios. The results suggest that ambitious plastic focused policies can result in lower costs and less cumulative emissions compared to ambitious climate focused policies. The results demonstrate the importance of adopting CCS for waste incineration. This reduces cumulative CO2 emissions by up to 2 Gt. However, reduced overall demand and increased recycling rates should be priority options due to CCS challenges. Results suggest Chinese ethylene industry should adopt a mixed portfolio of production technologies, where the share of emission-intensive coal-based methanol-to-olefins is limited. These findings on decarbonization pathways can contribute to achieving the Paris agreement.
