Promising climate progress from net-zero ambitions to the Paris Agreement goal
Open AccessIsabela Schmidt Tagomori, Fabio A Diuana et al.ARTICLENature Climate Change2026
Climate targets require strong commitments from countries to be achieved. Using a multi-model analysis, we show that current net-zero pledges bring the world closer to a well-below 2 °C pathway, but an emission gap remains. Increasing ambition will be crucial: expanding the global coverage of net-zero pledges and speeding up action increases consistency with the Paris Agreement (1.5–2.0 °C range in model mean). However, reaching the 1.5 °C goal w…

Feasibility of peak temperature targets in light of institutional constraints
Open AccessChristoph Bertram, Elina Brutschin et al.ARTICLENature Climate Change2024
Despite faster-than-expected progress in clean energy technology deployment, global annual CO 2 emissions have increased from 2020 to 2023. The feasibility of limiting warming to 1.5 °C is therefore questioned. Here we present a model intercomparison study that accounts for emissions trends until 2023 and compares cost-effective scenarios to alternative scenarios with institutional, geophysical and technological feasibility constraints and enable…
How climate change is impacting the Brazilian agricultural sector: Evidence from a systematic literature review
Open AccessAna Carolina Oliveira Fiorini, Gerd Brantes Angelkorte et al.ARTICLEEnvironmental Research Letters2024
Climate change is one of the biggest threats to global food security, with observed impacts already affecting agriculture. This study aims to systematize and analyze the observed biophysical impacts and their evolution in agriculture in Brazil. For this, we carry out a systematic literature review that includes 1844 articles in the first stage, and 53 articles with synthesized information retrieved. Temperature and precipitation are the most stud…

Sustainable aviation fuels must control induced land use change: An integrated assessment modelling exercise for Brazil
Open AccessAna Carolina Oliveira Fiorini, Gerd Brantes Angelkorte et al.ARTICLEEnvironmental Research Letters2022
Bio-sustainable aviation fuels (bio-SAFs) are an important pillar of the aviation sector decarbonisation strategy in the mid-term. Here we assess the induced Land-Use Change (LUC) implications of producing bio-SAFs in Brazil under different assumptions of forest conservation governance. We evaluate four bio-SAF routes via two main pathways: the Alcohol-to-Jet (ATJ) and the Hydroprocessed Esters and Fatty Acids (HEFA) syntheses. We chose the most …

Exploring the possibility space: Taking stock of the diverse capabilities and gaps in integrated assessment models
Open AccessIlkka Keppo, Isabela Butnar et al.ARTICLEEnvironmental Research Letters2021
Integrated assessment models (IAMs) have emerged as key tools for building and assessing long term climate mitigation scenarios. Due to their central role in the recent IPCC assessments, and international climate policy analyses more generally, and the high uncertainties related to future projections, IAMs have been critically assessed by scholars from different fields receiving various critiques ranging from adequacy of their methods to how thei…

Implications of various effort-sharing approaches for national carbon budgets and emission pathways
Open AccessNicole J van den Berg, Heleen Van Soest et al.ARTICLEClimatic Change2020
The bottom-up approach of the Nationally Determined Contributions (NDCs) in the Paris Agreement has led countries to self-determine their greenhouse gas (GHG) emission reduction targets. The planned ‘ratcheting-up’ process, which aims to ensure that the NDCs comply with the overall goal of limiting global average temperature increase to well below 2 °C or even 1.5 °C, will most likely include some evaluation of ‘fairness’ of these reduction targe…
Taking stock of national climate policies to evaluate implementation of the Paris Agreement
Open AccessMark Roelfsema, Heleen Van Soest et al.ARTICLENature Communications2020
Many countries have implemented national climate policies to accomplish pledged Nationally Determined Contributions and to contribute to the temperature objectives of the Paris Agreement on climate change. In 2023, the global stocktake will assess the combined effort of countries. Here, based on a public policy database and a multi-model scenario analysis, we show that implementation of current policies leaves a median emission gap of 22.4 to 28.…
The power of light: Socio-economic and environmental implications of a rural electrification program in Brazil
Open AccessPaula Bezerra, Paula Borges da Silveira Bezerra et al.ARTICLEEnvironmental Research Letters2017
Universal access to electricity is deemed critical for improving living standards and indispensable for eradicating poverty and achieving sustainable development. In 2003, the ‘Luz para Todos’ (LpT—Light for All) program was launched aiming to universalize access to electricity in Brazil. The program focused on rural and isolated areas, also targeting to bring development to those regions along with electrification. This paper evaluates the resul…
