Environmental payoffs of LPG cooking in India

Over two-thirds of Indians use solid fuels to meet daily cooking energy needs, with associated negative environmental, social, and health impacts. Major national initiatives implemented by the Indian government over the last few decades have included subsidies for cleaner burning fuels like liquid petroleum gas (LPG) and kerosene to encourage a transition to these. However, the extent to which these programs have affected net emissions from the use of these improved fuels has not been adequately studied. Here, we estimate the amount of fuelwood displaced and its net emissions impact due to improved access to LPG for cooking in India between 2001 and 2011 using nationally representative household expenditure surveys and census datasets. We account for a suite of climate-relevant emissions (Kyoto gases and other short-lived climate pollutants) and biomass renewability scenarios (a fully renewable and a conservative non-renewable case). We estimate that the national fuelwood displaced due to increased LPG access between 2001 and 2011 was approximately 7.2 million tons. On aggregate, we estimate a net emissions reduction of 6.73 MtCO2e due to the fuelwood displaced from increased access to LPG, when both Kyoto and non-Kyoto climate-active emissions are accounted for and assuming 0.3 as the fraction of non-renewable biomass (fNRB) harvested. However, if only Kyoto gases are considered, we estimate a smaller net emissions decrease of 0.03 MtCO2e (assuming fully renewable biomass harvesting), or 3.05 MtCO2e (assuming 0.3 as the fNRB). We conclude that the transition to LPG cooking in India reduced pressures on forests and achieved modest climate benefits, though uncertainties regarding the extent of non-renewable biomass harvesting and suite of climate-active emissions included in such an estimation can significantly influence results in any given year and should be considered carefully in any analysis and policy-making

Solar has greater techno-economic resource suitability than wind for replacing coal mining jobs

Coal mining directly employs over 7 million workers and benefits millions more through indirect jobs. However, to meet the 1.5 °C global climate target, coal's share in global energy supply should decline between 73% and 97% by 2050. But what will happen to coal miners as coal jobs disappear ?Answering this question is necessary to ensure a just transition and to ensure that politically powerful coal mining interests do not impede energy transitions. Some suggest that coal miners can transition to renewable jobs. However, prior research has not investigated the potential for renewable jobs to replace 'local' coal mining jobs. Historic analyses of coal industry declines show that coal miners do not migrate when they lose their jobs. By focusing on China, India, the US, and Australia, which represent 70% of global coal production, we investigate: (1) the local solar and wind capacity required in each coal mining area to enable all coal miners to transition to solar/wind jobs; (2) whether there are suitable solar and wind power resources in coal mining areas in order to install solar/wind plants and create those jobs; and (3) the scale of renewables deployment required to transition coal miners in areas suitable for solar/wind power. We find that with the exception of the US, several GWs of solar or wind capacity would be required in each coal mining area to transition all coal miners to solar/wind jobs. Moreover, while solar has more resource suitability than wind in coal mining areas, these resources are not available everywhere. In China, the country with the largest coal mining workforce, only 29% of coal mining areas are suitable for solar power. In all four countries, less than 7% of coal mining areas have suitable wind resources. Further, countries would have to scale-up their current solar capacity significantly to transition coal miners who work in areas suitable for solar development.publishedVersio

Ujjwala at 6 crores: Impact on Cooking Energy Transition and Climate Change

The Pradhan Mantri Ujjawala Yojana (PMUY) has been praised as a landmark initiative that has empowered six crore poor rural women to buy Liquefied Petroleum Gas (LPG) as the primary source for cooking. Having an LPG stove in the kitchen has always been an aspiration, which was unaffordable to many, until the capital cost support became available through PMUY in the form of subsidies and a loan facility. However, public debate over whether the beneficiaries are purchasing enough refill cylinders has emerged. In this article we analyze aggregated LPG refill numbers of PMUY beneficiaries by state, and discuss this within the larger perspective of clean cooking transitions and climate change. The pertinent question that remains to be answered is whether the Indian rural population is making a transition towards cleaner fuels like LPG though the advent of PMUY. Therefore it is essential to understand the refill rates of PMUY beneficiaries. In section 2 we discuss inter-state differences in PMUY refill trends and suggest recommendations for policy. Moreover, it is also necessary to also examine the potential impact of LPG consumption by PMUY beneficiaries on the environment(section 3)

Meeting well-below 2°C target would increase energy sector jobs globally

To limit global warming to well-below 2°C (WB2C), fossil fuels must be replaced by low-carbon energy sources. Support for this transition is often dampened by the impact on fossil fuel jobs. Previous work shows that pro-climate polices could increase employment by 20 million net energy jobs, but these studies rely on Organisation for Economic Co-operation and Development (OECD) jobs data, assumptions about jobs in non-OECD countries, and a single baseline assumption. Here we combine a global dataset of job intensities across 11 energy technologies and five job categories in 50 countries with an integrated assessment model under three shared socioeconomic pathways. We estimate direct energy jobs under a WB2C scenario and current policy scenarios. We find that, by 2050, energy sector jobs would grow from today's 18 million to 26 million under a WB2C scenario compared with 21 million under the current policy scenario. Fossil fuel extraction jobs would rapidly decline, but losses will be compensated by gains in solar and wind jobs, particularly in the manufacturing sector (totaling 7.7 million in 2050)

Green jobs and just transition: Employment implications of Europe's Net Zero pathway

The European Green Deal promises a “just and inclusive transition” to net-zero emissions by 2050, but employment implications remain poorly quantified. We address how Europe's net-zero transition affects energy sector employment and whether current policies ensure a just transition for affected workers. While the net-zero transition creates substantial net employment gains, we argue that significant mismatches in skills, geography, and timing require more targeted policy interventions than currently provided. Using the WITCH integrated assessment model coupled with global employment factors, we estimate changes across five job categories and eleven energy technologies for EU member states under current policies and the Net Zero emission target by 2050. Results show Europe's energy jobs increase substantially by 2050: from 1.3 million today to over 2 million under current policies and 2.5–3 million under Net Zero. Renewable energy accounts for 80 % of total energy jobs by 2050 under Net Zero, with solar PV representing three-quarters of job growth due to high labor intensity, while wind contributes 15 %. However, 300,000 jobs are lost in the coal and oil sectors under Net Zero (versus 100,000 under current policies), concentrated in Poland, Germany, and the Czech Republic. We also analyze the EU Just Transition Fund allocations to assess policy alignment and find a policy emphasis on addressing fossil fuel phase-out impacts rather than facilitating workforce transition to renewable energy. While coal-dependent countries receive substantial funding, critical gaps exist in skills development programs necessary for renewable energy expansion

A decentralized approach to model national and global food and land use systems

The achievement of several sustainable development goals and the Paris Climate Agreement depends on rapid progress towards sustainable food and land systems in all countries. We have built a flexible, collaborative modeling framework to foster the development of national pathways by local research teams and their integration up to global scale. Local researchers independently customize national models to explore mid-century pathways of the food and land use system transformation in collaboration with stakeholders. An online platform connects the national models, iteratively balances global exports and imports, and aggregates results to the global level. Our results show that actions toward greater sustainability in countries could sum up to 1 Mha net forest gain per year, 950 Mha net gain in the land where natural processes predominate, and an increased CO2 sink of 3.7 GtCO2e yr−1 over the period 2020-2050 compared to current trends, while average food consumption per capita remains above the adequate food requirements in all countries. We show examples of how the global linkage impacts national results and how different assumptions in national pathways impact global results. This modeling setup acknowledges the broad heterogeneity of socio-ecological contexts and the fact that people who live in these different contexts should be empowered to design the future they want. But it also demonstrates to local decision-makers the interconnectedness of our food and land use system and the urgent need for more collaboration to converge local and global priorities.Fil: Mosnier, Aline.

Culture, tradition, and taboo: understanding the social shaping of fuel choices and cooking practices in Nigeria

Wood fuel remains the most widely used domestic fuel amongst resource poor groups in many low-income countries, despite the environmental and health problems associated with exposure to wood smoke. Studies on household air pollution concentrate predominately on socio-economic and behavioural factors and health with little emphasis on socio-cultural factors. The study contributes to the understanding of household air pollution (HAP) and wood fuel harvesting for domestic activities in low-income countries from a cultural perspective that draws on householders’ wood fuel selection and cooking practices in Ado Ekiti, Nigeria. In this paper, we explore how cultural norms influence households’ cooking practices, energy choices and perceptions of the causes of ill health and misfortune. The research draws on household surveys, participant observation and semi-structured interviews with householders of four different ethnic origins in nineteen villages. Key findings reveal low levels of awareness of HAP-related illness coupled with high levels of attachment to traditional biomass-fuelled cooking systems for a range of cultural and pragmatic reasons. It is argued that ‘ethnic-specific’ traditional norms and taboos provide a more important influence on fuel choice, wood fuel harvesting and cooking practices than the lived realities of exposure to household air pollution
